Important Facts You Should Know About
Alpha Hydroxy Acids
and Reviva's Glycolics Acid

In skin clinics, Glycolic Acid has proven to be the most effective of the various alpha hydroxy acids (which include lactic acid, citric acid, malic acid and tartaric acid). Glycolic, derived from sugar cane, has the smallest molecular size --- which means it penetrates the skin more effectively to induce exfoliation (dead cell removal) and cell renewal.

At Reviva, our AHA products feature the unique polymer form of glycolic acid --- far different than those in the mass market. The polymer is "strands" of glycolic. These glycolic strands enter the skin's own natural polymer structure where their acidity is gradually released by a slow breaking down of the polymer chain. The glycolic polymer is not only more readily absorbed by skin, it has time-release action!

The polymer is one major quality difference; but there are more. For example, a very popular brand features a 70% solution of glycolic acid. This means that the glycolic is diluted (30% less strength). The glycolic extract used in our #381 GLYCOLIC ACID RENAISSANCE CREAM is full-strength glycolic crystals ... 100% glycolic extract...not diluted!

The percentage of glycolic acid in a product is important. But the pH (acidity measurement level) of the finished product is just as important. Our special glycolic line is formulated at a pH of 3-4. Above 4.5 pH, the glycolic acid would be too weak to do much good. To avoid stinging or irritation, some glycolic creams on the market have a pH of 5 or higher. But, some stinging is normal if the product is working and has the proper acid balance. Our glycolics are acidic enough to have effect ... and added anti-irritant ingredients to help avoid any more than a very brief stinging feel.

The difference between
Reviva GLYCOLIC ACID CREAM
and our LIGHT SKIN PEEL

There are generally 14-16 layers of dead cells on most skins. Glycolic acid can remove approximately 4 layers of these dead, dulling cells --- but it could take 5-6 weeks or more. LIGHT SKIN PEEL, the all-natural exfoliant that has been used in professional skin clinics for over 20 years, removes just one layer of dead cells---but does this immediately, in one 5-minute treatment. Even with one layer of dead skin removed, you can see clearer, softer, smoother skin.

LIGHT SKIN PEEL: perfect for home use once a week ... Glycolics for everyday.
