Hyaluronic Acid: Applied Vs. Injected

When it comes to replenishing the skin with lost moisture, hands down, the best choice is hyaluronic acid, which is naturally produced by the body.

Many skincare companies are incorporating hyaluronic acid into daily-use products as a way of increasing moisture, and some companies even claim results that rival those of dermal fillers. However, when applied topically, hyaluronic acid is unable to penetrate the epidermis. It can trap some moisture on the surface, but it must be combined with an oil, glycerin or another complementary ingredient to be effective.

Hyaluronic acid in fillers has a large molecular weight, and when injected, it binds 1,000 times its weight in water. Many doctors feel injections are the way to go for long-term results, because when it's applied topically, hyaluronic acid's benefits last for only a few hours.
