Ingredients higher up in an ingredient list are typically present in a larger amount. You may know this ingredient as argan oil. It has emollient and skin conditioning properties that help soften skin and reinforce the lipid barrier. The fatty acid profile of argan oil is roughly 45-55% oleic acid, 28-36% linoleic acid, 10-15% palmitic acid, and 5-7% stearic acid. It also contains vitamin E, sterols, squalene, and polyphenols like ferulic acid. Two clinical studies in postmenopausal women found that applying argan oil for 60 days significantly improved skin elasticity and moisturization (reduced transepidermal water loss and increased epidermal water content). Since it is high in oleic and linoleic acid, this ingredient may not be fungal acne safe. Both of these fall in the C11-C24 range that Malassezia yeast can metabolize. Bisabolol is a gentle skin conditioner, antioxidant, and soothing ingredient. It's primary claim to fame is soothing and research shows topically applied bisabolol can quiet the chemical messengers that cause your skin to become inflamed, helping to sooth any irritation. A clinical study found that applying 0.5% bisabolol daily for 8 weeks produced an average 9% decrease in skin pigmentation. Researchers found it can also suppress the process that leads to excess melanin production in skin. In vitro studies found that bisabolol combined with propylene glycol significantly increased skin permeability by increasing lipid fluidity in the stratum corneum. You'll likely see use concentrations quite low, usually 0.1-0.2%. Overall, this is a well-tolerated ingredient that works well in formulas designed for sensitive, reactive, or post-procedure skin. Butylene Glycol (or BG) is used within cosmetic products for a few different reasons: Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients. Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness. C12-15 Alkyl Benzoate is a lightweight emollient made by combinig benzoic acid with fatty alcohols that are 12-15 carbons long. In cosmetics, it plays several roles: The Cosmetic Review Expert Panel has concluded the alkyl benzoate group to be safe as used in cosmetics; it wasn't found to be a skin irritant and unlikely to be absorbed due to its low water solubility. This report recorded almost 1000 reported uses with concentrations up to 59% in leave-on products but your cosmetics will typically use 0.5-15% depending on the product. It's often called a "SPF booster": this is because it keeps UV filters properly dissolved and evenly distributed to support a sunscreen's performance. It doesn't actually raise SPF on its own. Overall, this ingredient is well tolerated. This ingredient is fungal acne safe because it is an ester of benzoic acid. Think of this ingredient as two parts stuck tog
