To prevent pimples from acne vulgaris, keep your skin clean by washing your face twice daily with a gentle cleanser, use oil-free (non-comedogenic) moisturizer and sunscreen, and avoid touching or picking your face. Limit oily foods, manage stress, and keep hair and pillowcases clean. If you?re prone to acne, using products with salicylic acid or benzoyl peroxide can help prevent breakouts, and regular care works better than short-term treatments.

Blemishes and marks after acne are common and usually include dark spots (post-inflammatory pigmentation) or mild scars from acne vulgaris. Use a gentle face wash, apply a sunscreen daily, and consider creams with ingredients like niacinamide, vitamin C, or retinoids to gradually lighten marks and improve skin texture. Avoid picking pimples, keep skin moisturized, and if marks are deep or persistent, consult a dermatologist for treatments like chemical peels or laser therapy.

To manage back and facial acne from acne vulgaris, use a gentle face/body wash with salicylic acid or benzoyl peroxide, bathe after sweating, and wear loose, breathable clothing to reduce oil and friction on the back. Apply oil-free moisturizer and avoid picking pimples to prevent marks. For the face, keep a simple routine with a mild cleanser, sunscreen, and, if needed, a topical retinoid at night. If acne is severe, painful, or persistent, consult a dermatologist for stronger treatments.
