I would like to start by recommending a daily skincare routine for the problems you are facing. Start with Oil control cleansers with AHA's or BHA's to clear the oil and dirt from your face 2-4 times a day. Use a Vit C serum or day serum in the morning if you are at home and you can add sunscreen on top if you are going to go out and will get exposed to sunlight. Evening, after wash use a toner to neutralize and calm your skin. Before bed, use a coat of moisturizer and additional retinol-based anti-aging serum to finish. If it's a major concern, please contact a dermatologist.
