The TCA 20% medium strength peel is perfect for experienced TCA users looking for a deeper peel with heavier peeling and who do not mind up to 2 weeks of downtime. This peel will help firm and tighten sagging skin and will address deeper wrinkles and texture issues. It is highly recommended to first begin building up the skin's tolerance by using the TCA 10% Peel first with good results. TCA 20% is NOT recommended for darker skin tones due to the increased risk of post-inflammatory hyperpigmentation.
