Large open pores are commonly caused by excess oil, acne (pimples), and reduced skin elasticity. Use a gentle cleanser and non-comedogenic products containing salicylic acid or niacinamide to help clear pores and improve skin texture. Also, apply a broad-spectrum sunscreen daily, as sun exposure can reduce skin elasticity and make pores appear larger. If the problem persists, a dermatologist may suggest treatments such as topical retinoids, chemical peels, or laser therapy.

Acne scars can be improved over time with consistent care. Use gentle cleansing, sunscreen daily, and products with ingredients like niacinamide, vitamin C, or retinoids to lighten marks. For deeper scars, consult a dermatologist for treatments to smooth the skin.

Dark pimples on the face and forehead are often caused by acne, clogged pores, excess oil, hormonal changes, or post-inflammatory pigmentation after pimples heal. To treat them, keep your face clean with a gentle cleanser, use non-comedogenic products, and apply acne-fighting ingredients like salicylic acid, benzoyl peroxide, or niacinamide. For stubborn dark marks, consult a dermatologist for treatments.
