The question

Is my skin barrier damaged?

What's happening in your skin

The barrier is the outer layer of skin cells held together by lipids, mostly ceramides: bricks and mortar. Over-cleansing, over-exfoliating, and stacking actives dissolve the mortar. Water escapes, irritants get in, and everything you apply stings. Oily skin often responds by producing more oil, so a damaged barrier can be both flaky and greasy at once.

What the research shows

1. Acne-prone skin has barrier dysfunction and reduced ceramides; a ceramide cleanser and moisturizer during acne treatment lowered water loss, dryness, and inflammatory lesion counts.

2. African American skin has been found to have lower ceramide levels, consistent with a high rate of dryness, though a 2022 study at one facial site found no difference.

3. Alkaline cleansers destabilize barrier lipid structure compared with mildly acidic ones.

Our answer

If moisturizer stings, your barrier is damaged, and nothing else will work until it's repaired. Stop all actives, cleanse gently once a day, use a ceramide moisturizer morning and night, sunscreen in the morning, and give it two to eight weeks.
