Occlusive acne is also called closed acne. Acne has a small impact on appearance, cannot be squeezed out and is slow to treat. The most common medications used for this disease are topical and oral anti-follicular keratinization medications. If the acne grows scattered and the pain and itching is not obvious, it can be treated with topical medication only, commonly used is vitamin A acid cream or adapalene gel, a course of treatment is more than 2 weeks. If the pimples are partially red or painful, antibiotic creams such as erythromycin ointment or fusidic acid cream may be added. For denser and more widespread acne, oral antikeratotic medications, most commonly retinoids, such as retinoid capsules or isotretinoin softgels, may be added. In addition to medication, you can use red and blue light treatment, which is also very effective for acne. If you have acne, you need to pay attention to your diet, go to bed early, get up early, don’t stay up late, eat less spicy and greasy food, beef, mutton, seafood, and don’t drink alcohol.
