By combining the Glycolic and Lactic acids in a single peel you get the superior moisturizing properties of the Glycolic acid without the excessive dryness. It is also significantly stronger than the Glycolic/35 or Lactic/35 used individually.
Lactic acid is most often found in moisturizers due to its moisturizing properties. It is a natural humectant that draws in and holds water within the outer layers of the skin. Alpha hydroxy acids as a whole can increase the skin’s ability to trap water due to an increased production of natural skin moisturizers (hyaluronic acid), but Lactic acid’s extra humectant properties make it ideal for treating dry skin.
Also, because Lactic acid is naturally found in the human body, it is not likely to cause an allergic reaction in those with reactive skin. The glycolic has a smaller molecule and is best at collagen stimulation, because it can penetrate deeper beneath the skin, the lactic is best at improving tone and texture of the skin, as well as helping the skin to hold and retain more moisture because of its humectant properties.
The moisturizing properties of Lactic acid coupled with the exfoliating power of Glycolic acid make our Glycolic/Lactic combination an effective treatment for those with dryer or easily irritated skin. Lactic is typically best for pigmentation and evening tone, while the Glycolic is best for fine lines and general skin rejuvenation. The mixture gives a great combination of benefits.
Yes, the peel is safe for all skin types, but you should do a small test application first. Apply for 30 seconds and rinse off. Wait one day, and if no excessive irritation exists, you’re free to resume. When selecting the test site, remember you don’t want to peel the same area twice, so choose somewhere different than where you would like to initially apply the peel. (For example, don’t test on your face if you want to peel your face).
Our peels are generally very well tolerated, much more so than other peels with a low pH and high percentage of acid. This low application intensity is due to their formulation. Most peel products are formulated with an acetone/alcohol base. This works effectively to dissolve the Glycolic acid, and alcohol has the advantage that it is readily available, and very cheap.
The problem with alcohol is that it is very harsh. Upon application it strips away the outer layers of skin, and sensitizes nerve endings causing a tingling sensation. When combined with a high concentration of Glycolic acid, alcohol increases the application intensity even more. The alcohol and acetone solvents do drive the Glycolic acid more deeply into the skin, but I would not recommend this to be used on the face.
In formulating this product for the face, we wanted to create a peel treatment that would not be irritating to the skin. For this reason we could not use the alcohol which is normally used.
Instead we dissolve the Glycolic acid in a gelled environment of propylene glycol. This is quite a bit more expensive, but it allows us to create something that can be left on the face for a much longer time, without sacrificing acid strength.
