Ingredients higher up in an ingredient list are typically present in a larger amount. This ingredient is also called ethanol or ethyl alcohol. It is denatured, meaning made undrinkable for cosmetic use. In formulas, it: Is it bad for your skin? The answer comes down to concentration. Patch and wash studies have found highly concentrated alcohol-based hand rubs (60-100%) cause less barrier disruption than washing with a basic detergent like SLS. The only measurable effect in these studies was a temporary dip in skin hydration. Concentrations below 12-15% in leave-on cosmetics is generally well-tolerated. Concentrations above start to see increased transepidermal water loss (TEWL) and reduced hydration. In concentrations about 58%, it creates temporary channels in your skin's lipid layers to become more permeable and allow other ingredients to slip through easily. This ingredient can be up to 80% of the formula in alcohol-based perfumes. Overall, this ingredient is probably harmless if found lower down an ingredients list but worth side-eyeing if it's high up (especially if your barrier is already struggling). Alcohol can worsen dry skin, eczema, and oily skin, especially at higher concentrations. This is because it can increase transepidermal water loss and decrease hydration to disrupt the skin barrier. According to the National Rosacea Society based in the US, you should be mindful of products with these alcohols in the top half of ingredients. True allergic contact dermatitis to ethanol is uncommon, but be sure to patch test if you have dry or sensitive skin. Azelaic acid is a multitasker ingredient that helps treat acne, pigmentation, and irritation. It is a great option for sensitive skin. What makes it special? OTC Azelaic acid is usually available in concentrations from 10-15% and anything over requires a prescription. Here's what each tier does best: Unlike other acids, azelaic acid will not make your skin more photosensitive/sun sensitive. Though this ingredient is naturally occurring in grains like wheat, rye, and barley, it is usually synthetically created for cosmetics to ensure stability and effectiveness. Calcium Ascorbate is the calcium salt of L-ascorbic acid (Vitamin C). It is a water-loving form of vitamin C that's often discussed as being more formulation friendly and gentler than pure ascorbic acid (because ascorbic acid oxidizes easily in water-based products). In skincare, it is mainly used as an antioxidant and skin conditioning ingredient. Vitamin C is commonly used to support brighter and more even looking skin. There's some topical research suggesting calcium absorbate can be used in emulsions and may be helpful in skin hydration outcomes, but the best benefits of vitamin C are established for ascorbic acid.
