Effaclar Duo (+) — Reddit Reviews
Updated August 29, 2026
Salicylic acid spot treatment clearing cystic acne quickly; can irritate and dry skin.
What the community says
This gel uses salicylic acid and niacinamide to attack active acne and prevent new cysts. Users with stubborn spots or cystic acne often notice quick results, though it can irritate sensitive or dry skin and damage the barrier if overused. It's best for spot treatment, not full-face daily use.
