This medium depth peel has minimal to zero downtime due to it's biphasic technology. It bypasses the top layer of the skin going straight into the dermis to work from the inside out. Biphasic technology has two phases. These two phases are called Lipophilic and hydrophilic. Lipophilic which is the blue layer you see in the bottle, stabilizes, hydrates and moisturizes. Hydrophilic is the yellow layer that contains the 35% TCA that revitalizes and neutralizes free radicals. Together they give drastic transformations without excessive peeling or downtime.  To have optimal results this peel should be done in a series of 4. It can be done 7-10 days apart without causing any harm to the skin.
