Ingredients higher up in an ingredient list are typically present in a larger amount. Allantoin is a soothing ingredient known for its protective and moisturizing properties; it's basically a quiet workhorse ingredient you can find in a huge range of cosmetics. Though it can be derived from the comfrey plant, allantoin is produced synthetically for cosmetic products to ensure purity. Research shows it can encourage your skin cells to turn over and renew by stimulating keratinocyte and fibroblast proliferation. It also has mild keratolytic properties to help loosen and shed dead skin cells without being harsh. Studies also suggest allantoin can help calm inflammation by dialing down some of the chemical signals your skin sends out when it is irritated. This ingredient is typically used in the 0.1-0.5% range, and the FDA recognizes it as a skin protectant in OTC products up to 2%. Overall, allantoin is a wonderful addition to most routines; it is stable across a wide pH range (~4-8), works well with other ingredients, and is considered non-sensitizing/non-irritating. Fun fact: Allantoin is naturally occurring in comfrey root, beets, chamomile, and wheat sprouts. Our bodies even produce it as a byproduct of uric acid metabolism. Ceramide NP (formerly known as Ceramide 3) is one of the skin's naturally occurring lipids. Since ceramides are the major lipid components of the skin, they are crucial for maintaining skin barrier and hydration. Ceramide NP most closely mirrors the dominant kind in human skin amongst ceramide subtypes. This ceramide works by slotting into gaps within the stratum corneum's lipid matrix to limit trans-epidermal water loss (TEWL) and shield the skin against external irritants. A study with 312 patients found that using a ceramide-containing routine for 4 weeks reduced the severity of atopic dermatitis by over 61%. Another clinical study in subjects aged 60 and older found that a ceramide body wash and moisturizer improved skin dryness and itchy skin in 15 days. Overall, ceramides are considered non-irritating and safety tests have found little to no observable adverse effects from using this ingredient. Ceramide NP is usually sourced from plants (like soybean or rice bran), or produced synthetically. Dimethicone is a type of synthetic silicone created from natural materials such as quartz. It is also known as polydimethylsiloxane. What it does: Dimethicone comes in different viscosities: Depending on the viscosity, dimethicone has different properties. Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity. This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient. Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur whe
