LHA peel is a 4th generation peel that strengthens and reboots the skin core. The Peel & Fill contains LHA and lipids which allows gentle exfoliations and cause less irritation and other side effects. Unlike other traditional peeling, which was treated with acidic components, LHA peel was developed to be peeling using a neutral component of pH5.5 called LHA, by combining the key ingredients that can help solve various skin problems in an optimized ratio. It is recommended for people with sensitive skin due to low irritations, redness, itchiness and you can get back to normal routine after the treatment.
