Skin Benefits

Helps lift away excess sebum and sunscreen residue for a thorough cleanse while leaving skin feeling soft, though those prone to breakouts may find it congesting due to its higher comedogenic potential.

Uses In Skincare & Cosmetics

Common in bar soaps, foaming face washes, and shaving soaps; also appears in cream cleansers for richer cleansing textures.

Comedogenic Rating

Myristic Acid has a comedogenic rating of 4. It has a higher likelihood of clogging pores and may not be suitable for acne-prone skin.

Safety

Generally safe in cosmetics, with low irritation risk for most users. Notable comedogenic risk for blemish-prone skin, particularly in leave-on products; patch test if sensitive. No widely recognized regulatory restrictions for typical use levels.

Is Myristic Acid a Good Ingredient?

It's effective for boosting cleanse and lather, but its high comedogenic rating (around 4) means it can congest pores, especially in acne-prone skin, which is why it rates Fair. It's best suited to rinse-off formats, since leave-ons raise breakout risk.
