Formulating for Sensitive Skin

What is sensitive skin?

Sensitive skin is a lay term rather than a medical diagnosis. It is generally used to describe skin with reduced tolerance to the application of cosmetics and personal care products. In surveys, approximately 50% of women and 40% of men may report having sensitive skin.

The global sensitive skin care market is expected to reach US $80.1 billion by 2030, rising at a CAGR of 8.9% from 2023 – 2030.

Consumer Insights on Skin Sensitivity

As might be expected, consumer perceptions of sensitive skin may differ from dermatologist perceptions. For example, consumers frequently consider acne breakouts after product use to be a manifestation of sensitive skin, whereas to the dermatologist, these breakouts would fall under acnegenic or comedogenic conditions – and respective non-acnegenic and non-comedogenic product solutions.

Tips for Formulating Sensitive Skin Care

Formulating for sensitive skin can be challenging, since there is no agreed upon definition. However, the following highlights key and important points in the formulation of products suitable for sensitive skin.

Less is more: Fewer ingredients are better than more ingredients. Many individuals with sensitive skin may demonstrate irritant or allergic contact dermatitis to a variety of ingredients; therefore, it is less problematic to use simpler formulations with fewer ingredients.

Furthermore, many cosmeceutical and moisturizer formulations are characterized by a complex cocktail of botanical extracts, which can cause allergic contact dermatitis. A diagnosis of which plant-derived material is causing the problem is also challenging since plant materials are composed of many different constituents.

As such, basic formulations with justifications for the purpose of every ingredient work better in sensitive skin populations. Ingredients that are added for market distinction or enhanced aesthetics should be considered carefully.

Re-hydrate the skin: Humectants can hold water within the skin and also attract moisture from the surrounding atmosphere; helping it to stay plump, moist, and resist dehydration. Refined Glycerin known as a great humectant.
Avoid vehicles that rapidly evaporate upon skin contact: Another sensory issue with sensitive skin is the rapid evaporation of materials from the skin surface. While this evokes a pleasant sensation of cooling for many people, individuals with sensitive skin may find it annoying. Furthermore, the rapid evaporation of materials from the skin may evoke flushing and blushing in persons with rosacea.

Many substances that rapidly evaporate from the skin are light-weight alcohols, such as ethanol, sometimes used in toners and after-shave preparations. These types of formulations are generally not appropriate for sensitive skin.

Eliminate common allergens and irritants: It goes without saying that common allergens and irritants should be eliminated from sensitive skin formulations. However, the problem lies in identifying them. Irritants include anything that destroys the skin barrier, removes the intercellular lipids and denatures the proteins. Such ingredients include glycolic acid, lactic acid, urea, etc.

There is also the list of ingredients in dermatologists’ standard patch tests, including PPD, lanolin alcohol, parabens, fragrance mixes, formaldehyde, isothiazolinone, quaternium-15 and others. A quick look at this list might be helpful – although some ingredients are being phased out of cosmetic formulations.

skin friendly pH: One of the characteristics of healthy skin is the presence of what is known as the acid mantle. This entity is so-named because healthy skin has a pH of somewhere between 5.2 and 5.4.

Highly acidic (alpha-hydroxy acid products; pH of around 3.5) and highly alkaline (traditional soaps; pH of around 9.5) should not be marketed to people with skin sensitivities. This also means care when formulating male shaving foams using potassium or sodium hydroxide as they will, by the way they are created, have a pH above 9 which can be irritating.

Ensure ingredient purity: Ingredient purity is essential for sensitive skin formulations. For example, contamination of raw pigment materials with nickel, the most common metal allergen, must be avoided.
Avoid exfoliants: Lastly, exfoliants should be avoided as they can damage the fragile skin barrier in those afflicted by sensitive skin.

Glycerin and sensitive skin

Glycerin is also a good choice for sensitive skin. Because it’s a natural component of skin, it helps to visibly calm redness and inflammation. It’s one of the gentler ingredients you can find in skin care products and can even help alleviate signs of sensitivity over time.

Formulation of Baby Skin Care Products; Dos and Don’ts

The phrase “baby skin” immediately evokes exceptional softness and smoothness; however, for specialists and formulators, behind this delicate appearance lies a complex and sensitive reality. Baby skin has an immature protective barrier (Skin Barrier) that does not yet have sufficient capacity to cope with environmental factors, and its permeability is very high. This is precisely why the standards and criteria for selecting cosmetic and personal care raw materials for baby products have fundamental differences from adult products. A small mistake in selecting these compounds can lead to severe skin irritation. Therefore, safe formulation requires a deep understanding of skin physiology. In this article, we examine the characteristics of baby skin, formulation challenges, and the list of compounds approved by the FDA.

Understanding the Characteristics and Sensitivities of a Baby’s Developing Skin

Baby skin is not merely a smaller version of adult skin; rather, it has specific structural and functional differences that require special care. Below, three main characteristics and the physiological challenges associated with them are examined:

Thinner Stratum Corneum

Compared with adults, babies have a Stratum Corneum that is approximately 30 percent thinner, and the distance between the cells of this layer is also greater.

Physiological Challenges of Baby Skin:

Lower ability to retain moisture
Increased rate of water absorption and loss (which can cause dry skin)
Greater vulnerability to chemicals and high permeability to topical substances, which in some cases increases the likelihood of sensitivity or even toxic effects.

Formation of the Protective Acid Mantle (Acid Mantle)

Sebaceous glands and sweat glands in babies are less active; therefore, the protective acid mantle of the skin has not yet fully formed. This is why baby skin has a neutral pH during the first few days, while adult skin is naturally acidic.

Physiological Challenges of Baby Skin:

Greater possibility of contact with and growth of microorganisms on the skin
Greater vulnerability to infections and skin irritations such as diaper rash
High tendency toward dry skin

Less Melanin

Baby skin contains a very small amount of coloring substances; therefore, it produces much less melanin compared with adults.

Physiological Challenge of Baby Skin:

Lack of natural protection against sunlight

Table Examining the Structural Characteristics of Baby Skin

Structural Characteristic of Baby Skin	Detailed Description	Physiological Challenge and Risks	Formulation Approach
Thin Stratum Corneum	30% thinner than adults with greater distance between cells	High permeability to chemicals and rapid water loss (dryness)	Use of strong emollients and removal of toxic/sensitizing substances
Immature Acid Mantle	Low activity of sebaceous and sweat glands (neutral pH at birth)	Susceptibility to microbial growth, fungal infection, and diaper rash	Precise adjustment of product pH and use of mild antibacterial compounds
Melanin Deficiency	Minimal pigment production by melanocytes	Lack of natural protection against solar UV radiation	Need for physical protection (no use of chemical filters in babies)

How to Select Suitable Chemical Raw Materials for Baby Products?

Avoiding Materials with Potential Risks for Babies:

Naturally, any material that has not been tested on baby skin in terms of its potential to cause sensitivity, allergy, or its level of absorption through the skin should not be used in the formulation of baby products. For example, very strong detergents such as sodium lauryl sulfate, excessive or very strong preservatives, degreasing agents, PEG-containing additives, and fragrances are better avoided in baby products. However, these substances are not inherently dangerous and do not necessarily need to be removed from adult products; rather, it is recommended that these substances themselves and formulations containing them be evaluated and tested before use on baby skin. It should also be noted that although natural preservatives can be beneficial in some baby products, their safety on baby skin has not always been fully evaluated; therefore, caution should also be exercised when using them.

Use of Suitable Emollients and Moisture-Retaining Agents for Babies:

Baby skin requires special care to restore lipids and protect its natural barrier; therefore, moisturizers, moisture-retaining agents, and emollients are ideal options for baby skin care formulations. Dimethicone is particularly considered a safe and highly effective ingredient in this regard. In fact, the U.S. Food and Drug Administration (FDA) has published a monograph that lists substances permitted for drug claims related to skin protection, including:

Dimethicone 1–30%
Glycerin 20–45%
Allantoin 0.5–2%
Petrolatum 30–100%

In general, any emollient that can prevent excessive water evaporation from the skin (TEWL) and maintain skin moisture is suitable, provided that it is not known to be a comedogenic agent (pore-clogging) or a sensitizer.

Important and Noteworthy Points in the Formulation of Baby Care Products

The production of baby care products requires a precise understanding of raw materials and their potential effects on baby skin. The market is highly receptive to products produced based on renewable, natural, or nature-inspired resources. In addition, the product pH should be close to the natural pH of baby skin, and the concentration of active ingredients and preservatives should be adjusted according to safety standards. Conducting specific skin tests for babies before launching the product will ensure the safety and effectiveness of the product.

Safety Tests and Standards

Baby products should be manufactured and tested according to international standards. Conducting clinical and laboratory tests before launch, in addition to ensuring safety, also helps build parents’ trust.

Marketing Trends and Parental Attention

Today, parents are paying more attention than ever to natural resources and safety. Products manufactured with safe and natural ingredients gain greater trust and perform better in the market. This trend has led manufacturers to use vernix-inspired compounds and skin barrier-repairing materials in their formulations.

Conclusion:

Baby skin is not merely a smaller version of adult skin, but rather has a physiological structure with unique characteristics. The 30% thinner Stratum Corneum, immature acid mantle, and low activity of sebaceous glands make this skin highly vulnerable to the penetration of chemicals and moisture loss. Therefore, the art of baby product formulation lies in the intelligent selection of raw materials; removing high-risk compounds such as SLS and strong parabens and replacing them with safe and FDA-approved materials such as Dimethicone, Glycerin, and Petrolatum. Ultimately, success in this market depends on producing products that, in addition to restoring the skin’s protective barrier, are inspired by natural resources and have successfully passed all safety and clinical tests before launch.

Frequently Asked Questions:

1. Why does baby skin dry out faster than adult skin?

Because the Stratum Corneum in babies is 30% thinner and the distance between its cells is greater. This structure causes the rate of water evaporation from the skin surface (TEWL) to increase, resulting in faster moisture loss.

2. Which substances does the FDA consider safe for protecting baby skin?

According to the FDA monograph, substances such as Dimethicone (1 to 30%), Glycerin (20 to 45%), Allantoin (0.5 to 2%), and Petrolatum (30 to 100%) are safe and effective for use in baby skin protection products.

3. Which compounds should not be used in baby product formulations?

The use of strong detergents such as sodium lauryl sulfate (SLS), strong preservatives, harsh degreasing agents, PEG-containing compounds, and allergenic fragrances is not recommended due to the high permeability of baby skin.

Trends Influencing Cosmetic and Personal Care Raw Materials Over the Next 25 Years

Chemical raw materials play a key role in various industries, including the beauty and personal care industry. In the coming years, the chemical raw materials industry will undergo profound transformation. Growing demand for sustainability, the rapid growth of biotechnology, and the development of biopharmaceuticals will fundamentally change the direction of this industry. Today, specialized raw materials are no longer just a part of formulations; they have become tools for creating innovation and competitive advantage.

Sustainability: From Corporate Goals to Product Sustainability:

The World Economic Forum’s “Global Risks 2024” report shows why environmental sustainability has become one of the most important priorities for the chemical raw materials industry. The major risks over the next decade include natural resource shortages, biodiversity loss, and extreme weather events caused by climate change, all of which are related to the environment.

Today, the impact of these challenges can be seen in consumer purchasing decisions. For example, a significant proportion of consumers prefer to purchase more sustainable products from companies that behave responsibly and provide solutions to address climate change. This trend will continue to grow, and therefore the influence of sustainability on business decision-making will increase, playing a much deeper role in shaping the specialized raw materials sector over the coming decades.

Sustainability claims are no longer limited to reducing greenhouse gas emissions, and greater attention will be given to carbon sources, biodegradability, and the end-of-life of products. In addition, the transition from petrochemical raw materials toward bio-based, recycled, and waste-derived materials will continue at a faster pace, and the share of petrochemical raw materials in the raw materials industry is expected to decline significantly over the next 25 years.

The implications of these trends are clear: sustainability is redefining the industry. Companies must review their methods and products throughout the entire supply chain to reduce environmental impacts while meeting the diverse needs of customers and the future market.

Biotechnology:

Biotechnology is already transforming traditional raw material production processes, and this trend is expected to continue over the next 25 years as attention to biotechnological solutions, particularly in pharmaceuticals and personal care products, continues to increase.

Personalization (Personalization):

Personalization will be one of the emerging developments in pharmaceuticals and personal care over the next 25 years. Imagine entering a store and receiving a product specifically tailored to your unique skin needs. This concept, which is still limited and specialized today, could become widely common in developed markets over the coming decades.

Artificial Intelligence (AI):

Artificial intelligence has become an effective tool in the raw materials industry; it accelerates the discovery of new materials, increases production efficiency, and improves demand forecasting. However, data quality remains a determining factor in the effectiveness of this technology.

Sustainable Solutions for Protecting Resources and the Environment:

Improper extraction of raw materials leads to resource shortages, habitat destruction, and biodiversity loss. The transition toward bio-based, recycled, and waste-derived resources is accelerating, and the share of petrochemical raw materials in the cosmetics industry is expected to decline significantly over the next 25 years. Sustainable carbon sources, including plant-based lignin and waste gas capture technologies, are becoming a major focus of the industry.

Challenges and Opportunities for the Raw Materials Industry in the Face of Demographic and Cultural Changes:

Economic growth in developing countries is outpacing that of developed markets, with Asia, the Middle East, and Africa emerging as important sources of future growth for this industry. This growth is largely driven by the expansion of the middle class and urbanization, resulting in greater penetration of personal care products across different cultures and markets around the world. As a result, raw material suppliers are required to consider cultural and ethnic differences in their product portfolios.

The aging population is also an important driver of consumption. According to World Health Organization statistics, by 2050, the proportion of people aged over 60 will reach 22%, compared with only 12% in 2015. Older people in developed markets generally have greater disposable income and fewer responsibilities, and therefore show a greater tendency toward luxury and impulse purchases. In addition, with increasing life expectancy, these consumers are looking for products that provide a greater sense of well-being and a more youthful appearance.

Today, beauty at every stage of life has become synonymous with well-being, self-confidence, and self-esteem. This trend creates an opportunity to provide better products and experiences for the aging population, which represents a growing share of the global population. All of these factors will have a significant impact on the raw materials industry.
