Some home acne treatments for adults include tea tree oil, toothpaste or contact lens solution. Apply a dab of tea tree oil, toothpaste or contact lens solution to blemishes overnight to dry and heal acne rapidly. Wash your face twice a day and use noncomedogenic moisturizer to prevent additional acne.
More home remedies and over-the-counter treatments for acne include steroid creams, retinoids, salicylic acid and benzoyl peroxide. Retinoids prevent pores from clogging up and creating more acne, while steroid creams reduce redness and irritation quickly. Salicylic acid dries up acne and blemishes and makes the top layer of skin peel. Benzoyl peroxide kills acne bacteria within the pores and reduces skin inflammation and oil production.
