Your symptoms suggest moderate acne (pimples) affecting both the face and back. The painful back lesions that sometimes bleed are likely deeper, inflamed acne spots. It is important not to squeeze them, as this may worsen the infection and lead to scarring. Continue using Sebamed Clear Face Cleansing Foam, as it is gentle and suitable for oily and acne-prone skin. You may use a topical treatment such as Faceclin AT gel, which contains Adapalene and Clindamycin. Apply a very thin layer at night on clean, dry skin, starting on alternate nights for 1 to 2 weeks, then increase use if your skin tolerates it. Mild dryness or irritation may occur initially. For back acne, a benzoyl peroxide wash once daily may help reduce bacteria and oil. Use a light non-comedogenic moisturiser and sunscreen during the day. If painful or deep lesions persist, you may need oral medication prescribed by a dermatologist after examination.
