Aditop C Gel makes skin sensitive, so you should avoid spending time in sunlight. If you have to be in sunlight, you should wear sunscreen and wear a hat and clothes that cover the areas treated with Aditop C Gel. You should avoid weather extremes such as wind and cold, as this may irritate your skin. Some skin products, such as harsh soaps, astringents, cosmetics that have strong skin-drying effects, should be avoided. In addition, products containing high levels of alcohol should be avoided, as they may further dry or irritate your skin.
