To revitalise the skin and always keep it fresh and
radiant has always been the goal of medical professionals and the cosmetic
industry. Retinoic Acid was the first chemical substance that obtained successful
results in skin revitalisation, although its
use was limited, because of its irritability on the more sensitive skins.
Glycolic Acid is currently the most popular chemical agent used by Dermatologists
and Plastic Surgeons, because of its ease of use, and the normality of the
skin during the treatment. These two substances have been shown to be very
efficient in the treatment of skin that has been damaged to a lower degree,
and can improve the more severely damaged photoaged skin. Generally, the more
severe skin lesions are deep in the epidermis and because of this, require
a more aggressive, and severe treatment, so that they can be effectively eliminated.
Different chemical peeling systems (Jessner Solution, Resorcine, and Liquid
TCA), Mechanical Peeling (Dermoabrasion) and Physical Peelings (CO2 and Erbium
YAG Lasers) were all developed to work deeply in the skin and remove more
complex epidermal lesions. Because of the complexity of these more aggressive
treatments, only a few medical professionals have been trained to work with
these peelings that cause large exfoliation. In an attempt to simplify the
peelings, which have the capacity to promote efficient epidermolysis, we are
using formulations containing Trichloroacetic Acid 30% (TCA) in the form of
a chelated lotion (a process that limits the penetration of the TCA into the
dermal layer, avoiding unnecessary necroses in this layer of the skin) The
resulting peeling is efficient and causes less localised inflammation. This
peeling requires that the medical professionals be properly trained. (Fig:1,
