W-hat is TCA? 

Today we are talking about TCA. TCA or trichloroacetic acid is commonly found in chemical peels. TCA comes in all sorts of concentrations from 5%-70%, this will determine the depth of the chemical peel. Most med-spas administer superficial to medium depth peels. Above 50% is a deep chemical peel and needs to be performed by a doctor in a surgical setting.  

Here at Mercy Grace, we have two different chemical peels that contain TCA. The first one is the Sensi Peel by PCA skin that contains 6% TCA and is considered a medium-depth peel. Great for first time chemical peels and those with sensitive skin. The next one we have is the Ultra Peel by PCA skin that contains 10% and is also considered a medium-depth peel. Excellent for reducing hyperpigmentation. We also have PRX, but this is very unique as it technically not a chemical peel but a bio-stimulator because it bypasses the top layer of the skin.

H-ow does TCA work? 

TCA breaks down keratin, which is a protein naturally found in the skin. Superficial and medium depth peels help break down this keratin on the top layer of the skin, called the epidermis and the top of the papillary dermis (deeper skin). By breaking down the keratin this helps reduce hyperpigmentation, improve the texture of the skin, reduce acne, reduce fine lines and wrinkles and help increase skin elasticity and hydration.  

Y- “WHY” is it important for you? 

Things like hyperpigmentation can be difficult and stubborn to treat. But chemical peels with TCA are a great solution! Chemical peels can be done as a single treatment for a skin refresh or done in a series for a more dramatic transformation. Downtime is minimal with the peels we offer at Mercy Grace. Typically flaking/peeling starts 48-72 hours after treatment and can last anywhere from 5-10 days. Not everyone peels but with our chemical peels, peeling does not equal results. The ingredients are still penetrating to help lighten the pigment, reduce the acne and reduce fine lines and wrinkles, what is peeling is dead skin cells. When you do dermaplaning before a chemical peel you tend to have less peeling because the dermaplaning helps remove the dead skin cells and allows the chemical peel to penetrate deeper. We give patients a post kit with products to use for the week or so following their peel. It is important to keep the skin hydrated and avoid sun/heat for the best results.
