Can squalane cause breakouts?

Look at the whole formula

Squalane is noncomedogenic, meaning it is not expected to clog pores. It can be used on oily or acne prone skin, especially when you want lightweight moisture rather than a thick cream. A bottle with squalane on the front still deserves a look at the rest of its formula, even if the headline ingredient would prefer all the credit. If you have sensitive skin, pay particular attention to fragrance, preservatives and dyes.1

Squalane is not squalene

Squalene occurs naturally in sebum, the oil your skin produces. Squalane is the more stable form used in skincare. Oxidized squalene, particularly squalene peroxide, has been linked to inflammation and the formation of comedones, meaning clogged pores. That is a different substance from the squalane in a facial oil. Acne also involves several factors: producing more skin oil alone is not enough to explain why acne develops.12

How to fit squalane into your routine

1. 1Cleanse gently. For oily skin, wash up to twice daily and after sweating, without scrubbing.
2. 2Apply lighter products, such as a toner or serum, before squalane.
3. 3Layer squalane over those lighter products to help reduce moisture loss. Squalane can serve as a moisturizer rather than automatically becoming an extra step.
4. 4Wear sunscreen outdoors. Squalane's role here is moisturizing.

Oily skin still needs moisturizer after cleansing. Choose products labeled noncomedogenic, and look for a gentle foaming cleanser rather than one intended to dry your skin aggressively. A harsh cleanser can irritate skin and trigger increased oil production.13

What if you break out after using it?

Stop using a product that irritates your skin rather than continuing through the reaction. New spots after starting a squalane product do not identify which ingredient is responsible. For persistent acne or blackheads, a dermatologist can help you work out what needs changing.13

If bumps cluster along your hairline, forehead or the back of your neck, check your hair products too. Oils from shampoos, conditioners and styling products can reach the skin and clog pores. Stop the offending product and wash residue from pillowcases, hats and headbands. Acne caused by hair products can take 4 to 6 weeks to clear after contact stops. If it has not cleared within 6 weeks, see a dermatologist.4
