Dermatologists' Simple Rules for a Stronger Skin Barrier
Rosemont, Ill. – November 02, 2026 -- A routine of just three products, a gentle cleanser, a moisturizer, and a broad-spectrum sunscreen with SPF 30 or higher, is the core of what the American Academy of Dermatology (AAD) recommends for National Healthy Skin Month this November.
A damaged skin barrier lets germs in and moisture out
The skin barrier is the outermost layer of skin. It is the first line of defense against pollution, environmental damage, inflammation, and infection, and it keeps moisture locked in. When it is compromised, germs can get inside and cause infection. Water loss can leave skin dry, flaking, tight, or rough.
A weakened barrier can also worsen eczema, psoriasis, rosacea, and acne. Warning signs include sensitive, reactive skin with redness, discoloration, burning, or stinging when products are applied.
