Applying over-the-counter topical anti-aging treatments can be a good way to plump up your skin, but it's the nutrient-based ingredients rather than the topical cosmeceutical treatments that most effectively reduce the appearance of wrinkles. Look for topical anti-aging products that contain retinol (which is vitamin A), peptides or hydroxyacids. These treatments don't protect you from the sun's damaging rays (which can lead to premature aging), so don't forget to apply sunscreen.
Also consider alternative products and old wives' tales, as some may have real benefits. Let's look at witch hazel, for example. Witch hazel has been used for years, anecdotally thought to be good at tightening the skin when applied topically. And as it turns out, there is some truth in the tale -- the herb witch hazel has anti-inflammatory properties, which means it helps boost your body's defense against cell damage.
