Ingredients higher up in an ingredient list are typically present in a larger amount. This ingredient is also known as shea butter. It is a plant-derived extract from the nuts of the Africa shea tree and one of the most well-studied emollients. Because it has a high concentration of fatty acids (primarily oleic, stearic, and linoleic) it is able to form a protective barrier on the skin's surface. This helps seal in moisture and prevents transepidermal water loss (TEWL). In vitro research found an increase in skin hydration by 58% and a decrease in TEWL by 37.8% after 24 hours of applying this ingredient (pretty impressive for a single ingredient!). Besides hydration, shea butter also contains triterpenes that have anti-inflammatory potential. In particule, lupeol cinnamate has shown the highest anti-inflammatory activity in vivo. Shea butter also contains vitamins A and E which may contribute to antioxidant activity. While Shea Butter has an SPF rating of about 3-4, it is not a sunscreen replacement. This ingredient may not be fungal acne safe because its fatty acids fall within the C11-C24 range that the Malassezia yeast can metabolize. Carbomer is a synthetic thickening and gelling agent. It's basically the ingredient that gives a lot of serums, gels, creams, and sunscreens their smooth, non-sticky texture. Although legally permitted at very high levels, carbomers are normally used at concentrations below 1%. It also needs to be neutralized to actually thicken, and because it is a large molecule, it doesn't really penetrate the skin barrier. Allergy-wise, the risk is very low. Clinical studies show carbomers have low potential for skin irritation/sensitization even at concentrations up to 100%. A 2024 UK study patch-tested 1,302 patients and found true allergy to the parent group of carbomer to be rare with no confirmed relevant reactions. Cera alba is beeswax, or the wax used by bees to make honeycombs. It is a texture-enhancer and emollient. A study from 2003 found beeswax to be a stronger emollient than ingredients such as petroleum jelly. As an emollient, beeswax helps hydrate the skin by creating a barrier on top. This barrier traps moisture in. Emulsifiers help prevent ingredients from separating. This helps create consistent texture. The structure of beeswax is mainly long-chain alcohols and the esters of fatty acids. There are three types of beeswax: yellow, white, and absolute. Yellow is pure beeswax taken from the honeycomb. White beeswax is created by filtering or bleaching yellow beeswax. Absolute beeswax is created by treating beeswax with alcohol. Beeswax used in cosmetics are purified. Beeswax has been used throughout history and even in prehistoric times. Some common uses for beeswax still used today are making candles, as a waterproofing agent, and polish for leather. Beeswax's wax esters are derived primarily from palmitic and oleic acid (C16 and C18:1). Both of these fall within t
