For painful acne, topical benzoyl peroxide, salicylic acid, or prescription retinoids (like adapalene) help reduce inflammation. Retinoids also improve acne marks and uneven skin tone by boosting cell turnover. To target dark spots, freckles, and uneven tone, ingredients like vitamin C, azelaic acid, and niacinamide are highly effective. For dark circles, look for eye creams containing caffeine or hyaluronic acid. Most importantly, daily application of a broad-spectrum sunscreen (SPF 30 or higher) is essential to protect your skin and prevent pigmentation from worsening. Please consult a dermatologist for a personalized plan, especially for painful, deep acne.
