It is an emollient that helps soften skin and reduce transepidermal water loss (TEWL). What sets it apart from heavier emollients is its ultralight, non-greasy feel. Once applied, this ingredient dries down quickly and leaves a dry, silky finish behind. This also helps improve spreadability and texture. This ingredient has an excellent safety-record and is non-irritating. Typical concentrations for cosmetics range from 0.5-62%. Research on Malassezia growth found no growth on fatty acid esters with chain lengths shorter than 12 carbons (it prefers C11-24). Since Coco-Caprylate/Caprate is built on C8 and C10 fatty acids, it is out of the range that Malassezia metabolizes, and therefore safe for fungal acne. Coco-Caprylate is a lightweight emollient made by combining coconut-derived fatty alcohols (caprylic and capric acid). Its primary role in formulas is as a skin-softening emollient with excellent spreadability (it's considered a plant-based alternative to silicone oils like dimethicone). This ingredient is considered safe for use and concentrations range from 0.5-62%. Caprylic and capric fall outside the C11-24 range that Malassezia feeds on, and a 2020 study found caprylic acid disrupted Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%. Sesamum Indicum Seed Oil is the cold-pressed oil from sesame seeds. It is an emollient and skin conditioning agent made up of roughly 82-85% unsaturated fatty acids, mostly linoleic (~41%) and oleic acid (~39%). This pairing gives it barrier-supporting and moisturizing properties. Linoleic acid, an essential omega-6 fatty acid, can be incorporated into complex skin lipids. Topical application has shown barrier repair, anti-inflammatory, and wound-healing effects in cell and animal studies. Beyond fatty acids, sesame oil brings something more distinctive to the table: It contains natural antioxidants sesamol, sesamolin, and gamma-tocopherol. These also give the oil notably high oxidative stability. One of the oil's key lignans, sesamin, has also demonstrated anti-inflammatory activity in preclinical models. A 2023 clinical study found that a single application of sesame seed oil to the forearms of 35 healthy women improved stratum corneum hydration (though it didn't outperform raspberry seed oil). The comedogenic rating of 1-3 depends on the type of sesame oil; unrefined carries a rating of 3 while refined sesame oil drops to a 1. This ingredient may not be safe for fungal acne as it contains fatty acids that can feed Malassezia. Apricot Kernel Oil PEG-6 Esters is an oil. This ingredient is also known as Macadamia Seed Oil. It's an emollient with a fatty acid profile that closely mirrors the skin's own lipid makeup. The palmitoleic acid content is especially notable as it's somewhat rare in plant oils.
