Dark spots from acne and melasma take time to improve and require consistent care. Using topical creams containing hydroquinone, azelaic acid, or niacinamide may gradually lighten the dark spots, and applying a high SPF sunscreen every day helps prevent them from worsening. A dermatologist can guide you on the safest and most effective treatment for your skin.

The combination of clindamycin (an antibiotic) and adapalene (a retinoid) for acne is commonly found in prescription gels, such as Cligel A Gel, Clindac Ap Gel, Acnicin Gel, and Adaple C Gel. You should consult your doctor to obtain a prescription for the appropriate formulation and strength.

Topical creams containing retinoids or alpha-hydroxy acids may help improve acne scars over time, while dark circles often respond better to products containing ingredients such as vitamin C, niacinamide, or caffeine. You should consult a dermatologist who can assess your skin and recommend safe, effective treatment.

For acute acne on the cheeks, a topical treatment containing ingredients such as salicylic acid, benzoyl peroxide, or retinoids may help reduce inflammation and prevent new lesions. Please consult a dermatologist for the most suitable option. Additionally, wash your face with a gentle cleanser, avoid harsh scrubbing, and do not pick or squeeze pimples, as this can worsen inflammation and cause scarring.

Yes, you can use A-Ret 0.025% Gel (Tretinoin 0.025% w/w) at the age of 19, but it should be used exactly as directed by a dermatologist. It is not a moisturizer, so do not apply it all over the face; instead, use only a thin layer on the affected areas with acne or open pores. The gel should be applied at night on clean, dry skin and left overnight, then washed off in the morning. Always use only a pea-sized amount, avoid sensitive areas such as the eyes and mouth, and apply sunscreen during the day, as tretinoin increases sun sensitivity. Mild dryness or peeling is common initially, but if irritation becomes severe, discontinue use and consult your dermatologist.
