For oily skin and acne scars, a tailored skincare routine is key. First, use a daily cleanser containing Salicylic Acid to control excess oil and clear pores. At night, apply a thin layer of a topical retinoid like Adapalene gel; this promotes cell turnover to fade scars and prevent new acne. A Niacinamide serum can also help reduce sebum and improve skin texture. Crucially, apply a daily, non-comedogenic, gel-based sunscreen (SPF 30 or higher), as sun exposure darkens scars. For deep, pitted scars, topical creams have limited effects, so I highly recommend consulting a dermatologist for procedures like chemical peels or microneedling.
