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.

Comedogenic Rating

Myristyl Myristate has a comedogenic rating of 5. It has a high likelihood of clogging pores and is generally avoided in acne-prone routines.

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.

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.
