How to solve the enlarged pores that appear after the acne goes down? I have two methods that are recognized and effective in modern medicine, and I recommend them to you here. The first is our mesotherapy, also known as “hydrafacial injection”. This is a kind of injectable skin care treatment, injection with the help of special equipment “water gun”, the need for beauty injections into the dermis layer immediately below the epidermis. I personally feel that after the acne, the enlarged pores are related to the imbalance of oil and water in the skin. When we inject a certain amount of hyaluronic acid into the dermis, the hyaluronic acid will grab water in the skin for hydration, and after the hydration is completed, the water-oil condition of the whole skin will be improved, and the problem of enlarged pores will be corrected to a certain extent. The second method is the invasive laser treatment, where the enlarged pores that appear after we have acne are mixed with the depressed scar formed on the skin. This is relatively tricky to deal with, and we need to use some invasive treatments to do so. For example, carbon dioxide fractional, erbium laser fractional, shine ion beam, Plasmapheresis fractional, etc. When we combine these modalities, we may have better results.
