Ratings

Overall Rating

Fair

Comedogenic Risk

High

High likelihood of clogging pores, generally avoided in acne-prone routines.

Is Myristyl Myristate a Good Ingredient?

It creates a rich, occlusive feel that benefits very dry areas, but its high comedogenic rating means a notable risk of clogged pores, which limits its suitability for acne-prone skin and keeps it at Fair.

Skin Benefits

Provides a velvety afterfeel and softens rough, flaky areas; it's best for very dry zones, since it can congest pores for acne-prone skin.

Uses in Skincare & Cosmetics

Used in occlusive night moisturizers, heavy body balms, and solid makeup formats such as primers or foundation compacts to improve slip and payoff.

Safety

Low likelihood of irritation, but it is highly comedogenic and may worsen breakouts or closed comedones, especially with frequent use. Patch testing is advisable for blemish-prone users.
