Can a skincare product cause acne even if it is non comedogenic?

Does non comedogenic mean a product cannot cause breakouts?

Non comedogenic means designed not to clog pores. These products are useful choices for acne prone skin because they avoid pore clogging in most people, rather than every person. The label concerns clogged pores, not a diplomatic agreement with every possible breakout. Look for non comedogenic or oil free cleansers, moisturizers and makeup, but judge a product by how your skin responds as well as what the packaging promises.234

Why do I break out from products labeled for acne prone skin?

Pore clogging and irritation are different problems. Fragrances and essential oils can irritate skin, and irritation can trigger acne or make existing acne worse. Acne treatments can also cause dryness, redness and peeling. A product aimed at acne prone skin can therefore be unsuitable for your skin even when its purpose is to help.12

Acne starts when follicles become blocked with oil and dead skin cells; bacteria and inflammation can contribute too. Hormones, family tendency, certain medicines and humidity also influence breakouts. Cosmetics that block follicles can provoke flares, but skincare is one possible contributor, not automatically the defendant whenever a spot appears. Stress can worsen acne, and dirty skin is not its cause.256

How do I test whether skincare is clogging my pores?

1. 1Remove one suspected skincare product from your routine for two weeks. Fewer breakouts during that time suggest the product was contributing.
2. 2Before introducing a new product, apply it to a small area of your face for one week.
3. 3If that area develops itching, burning or breakouts, do not expand application to your whole face.
4. 4If you notice none of those problems, start using the product across your face.

Add or remove only one product at a time, because replacing the whole shelf gives you several suspects and no useful alibi. Changing several products together makes it difficult to identify which one is causing trouble.1

Keep the rest of your routine gentle

Wash gently morning and night with a mild cleanser and warm water. Avoid hot water, scrubbing and repeated washing. Choose a water based, non comedogenic moisturizer, remove makeup before bed, and wear sunscreen daily. Do not squeeze blackheads or whiteheads: damaging the follicle can cause more clogged bumps, infection and scars.234

If a salicylic acid cleanser dries or irritates your skin, use a mild non comedogenic cleanser in the morning and the salicylic acid cleanser before bed. For dryness from an acne treatment, a fragrance free, non comedogenic moisturizer can help. If you take isotretinoin, apply moisturizer while skin is still damp after cleansing and whenever it feels dry.147

How long should I wait, and when should I get help?

The two week removal test is a clue about a product, not a deadline for acne to disappear. With persistent treatment, clogged bumps can start improving in eight to twelve weeks and take months to clear. Starting some acne treatments can temporarily worsen acne; isotretinoin can do this for one to two months. Tell your dermatologist if acne worsens while taking it.37

Get medical help for worsening acne, deep painful cysts, developing scars or acne that causes emotional distress. See a clinician if self care and nonprescription treatment have not helped after several months. Report medication side effects rather than treating a prescription as another product to remove during your skincare test.23
