Cocoa butter is a solid fat pressed from roasted cacao beans, composed mainly of oleic, stearic, and palmitic acid triglycerides that form a semi occlusive film on skin, slowing water loss and softening rough texture.
Cocoa itself contains catechin antioxidants with genuine free radical scavenging activity, but most of these compounds are removed or degraded during the pressing and refining process that yields the purified fat, so the antioxidant claims often marketed for cocoa butter apply more accurately to cocoa extract than to the butter itself.
A well controlled, double blind, placebo controlled trial specifically testing whether cocoa butter lotion prevents stretch marks during pregnancy found no meaningful benefit over placebo, directly contradicting one of its most common marketing claims.

Our team reviews ingredient research and uses up-to-date evidence to rate ingredients based on the categories below.
Best
Ingredients with the most rigorous and convincing evidence. These are the standouts backed by consistent findings across independent, peer reviewed clinical research.. When we call an ingredient Best, it has earned that distinction through genuine, reproducible proof that it improves skin.
Good
Reliable, well tolerated ingredients that do their job without complaint. They may not carry the headline benefits of a Best rated active, but they hydrate, stabilize a formula, or support the ingredients around them in ways that make a real difference in how a product performs and feels.
Average
Ingredients that are perfectly safe and serve a clear function, typically as an emollient, thickener, or filler, but do not offer any meaningful skin benefit beyond that basic job. Not a red flag, just not a reason to choose one product over another.
Bad/Worst
Ingredients with documented potential to irritate skin, disrupt the barrier, or trigger sensitization in some users, often synthetic fragrance, drying forms of alcohol, or certain essential oils. Not automatically a dealbreaker for every skin type, but worth knowing about before you commit to a product.
