Caprylic/Capric Triglyceride
Caprylic/Capric Triglyceride (CCT) is one of skincare's most versatile and beneficial ingredients, particularly valued for its ability to support skin barrier function while providing effective moisturization [1]. This gentle emollient, derived from coconut oil through careful processing, works by creating a protective layer on the skin that helps prevent moisture loss while keeping skin soft and supple [2].
For those with dry or sensitive skin (Types 1 and 2), CCT is particularly valuable as research shows it significantly reduces transepidermal water loss (TEWL) and increases skin hydration [1]. This has been demonstrated in clinical studies where a 15% concentration showed marked improvements in skin barrier function [2]. Those with balanced skin (Type 3) will find CCT provides just the right level of moisturization without feeling heavy or greasy. However, if you have oily or oily-sensitive skin (Types 4 and 5), you might want to look for products with lower concentrations of CCT, as its occlusive properties could potentially trap excess oils [2].
What makes CCT particularly interesting is its mild antimicrobial properties, which may help maintain a healthy skin microbiome [3]. While it's generally very well-tolerated, there have been rare documented cases of allergic reactions [4], so as with any skincare ingredient, it's wise to patch test first, especially if you have sensitive skin. The ingredient shows particular promise for those dealing with dry skin conditions, as its barrier-supporting properties help maintain skin hydration levels [2]. This makes it an excellent choice for those looking to improve their skin's moisture retention and overall health, regardless of skin type, though concentration preferences may vary.
