The nurse is teaching a group of adolescents about care for acne vulgaris. Which interventions will the nurse include in the teaching session? Select all that apply.

Rationale: A. Washing the skin gently twice a day helps remove excess oil and dirt without irritating the skin. B. Vigorous scrubbing and harsh astringents can irritate the skin and worsen acne. C. Picking or squeezing acne lesions can lead to scarring and infection and should be avoided. D. Tretinoin should be applied sparingly as it can cause irritation; liberal application increases the risk of skin dryness and redness. E. Tetracycline antibiotics increase sensitivity to sunlight, so sun avoidance and use of sunscreen are important to prevent burns.
