What it is
An ester created by reacting myristyl alcohol with the fatty acids from cupuaçu (Theobroma grandiflorum) seeds. Cupuaçu is a tropical fruit related to cacao, and its seeds are rich in moisturizing fats.
How it works
It sits on the skin's surface to form a lightweight, non-greasy film that reduces water loss (transepidermal water loss, or TEWL) and leaves skin feeling soft and smooth. It also helps other ingredients spread evenly.
Pros
Lightweight hydration
Provides a silky, non-greasy feel that works well for oily and combination skin types.
Low irritation potential
Rated very low on both irritation and comedogenic scales, making it safe for sensitive and acne-prone skin.
Cons and cautions
Limited research
There are fewer peer-reviewed studies on this specific ester compared to more common emollients like jojoba oil or squalane.
Not for extreme dryness
As a lightweight emollient, it may not provide enough moisture for very dry or compromised skin barriers.
Best for
- Anyone looking for a lightweight moisturizer
- People with oily or combination skin who want hydration without heaviness
Use caution if
- Those with known allergies to cupuaçu or related plants (rare)
