Teens can start using active ingredients when there's a specific skin concern—not just to follow trends. This usually happens around age 12–14, when puberty-related skin issues (like acne, oiliness, or blackheads) start showing up.
General guidelines for actives by concern:
✅ For acne-prone or oily skin:
-
Salicylic acid (BHA) – age 12+
Great for unclogging pores and treating blackheads. -
Benzoyl peroxide (2.5–5%) – age 13+
Helps kill acne-causing bacteria. Start low to avoid irritation. -
Adapalene (Differin) – age 13–14+
A gentle retinoid that can be used if acne persists (often over-the-counter now in some countries).
✅ For dull or uneven skin tone:
-
Niacinamide (2–5%) – age 13+
Balances oil, soothes redness, and supports the skin barrier.
✅ For sensitive, red, or irritated skin:
-
Azelaic acid (10%) – age 14+
Can help with acne, redness, and post-acne marks.
Important precautions:
-
Always start with one active at a time.
-
Introduce it slowly—2–3 times a week, then build up.
-
Moisturize and use sunscreen daily, especially with exfoliants or retinoids.
-
See a dermatologist for moderate-to-severe acne or if unsure.
Avoid for now:
-
High-strength retinoids, AHAs, peels, or anti-aging actives like vitamin C (unless recommended).
-
Layering too many actives—it can damage the skin barrier.
