If you want to repair sun damage, well the best thing is not to sustain that sun damage in the first place. However, if it’s already too late, which happens to the best of us, you can do something to reverse that sun damage to some degree. You won’t reverse any wrinkles that have already developed. However, you will be able to reverse some sun damage, which is more serious in the long run to be honest, and you can prevent more premature wrinkles from developing in general terms. This you can do by first of all using antioxidants and second of all using moisturizers. You won’t prevent actual aging in general, just premature aging, and frankly you won’t actually help yourself in other ways to reduce wrinkles that have already occurred. However, moisturized and antioxidant hit skin is brighter skin, more luminous skin, smoother skin, and otherwise less sun damaged skin. So while we would definitely prefer that you not sustain the skin damage in the first place, there are certainly ways to reverse it and otherwise deal with it in general terms. It is more of a matter of being prepared than anything else.
