The Performance Duo

The Performance Duo

A limited edition duo developed by dermatologic surgeon, Dr. Antony Nakhla, featuring two high-performance formulas: 

The Resurfacing Tonic (100 mL) 

A high potency chemical exfoliating treatment powered by Lactic and Glycolic Acid that resurfaces the skin’s outer layer and increases skin cell turnover. Clinically proven to improve skin texture, brighten dull skin, reduce the appearance of dark spots, minimize the look of pores, and leave skin feeling purified and more radiant.

The Regenerative Serum (15 mL) 

A patented formula featuring the highest concentration of our proprietary Peptide-rich Plasma® that stimulates the skin’s innate ability to renew, restore, and regenerate and addresses the 10 visible signs of skin aging.  

Paired together, this high potency system resurfaces and prepares skin to receive an infusion of advanced bioidentical ingredients for a firmer, plumper complexion.

Application

Dr. Nakhla recommends testing a small amount of the Resurfacing Tonic prior to applying to the entire face. This treatment may be used twice daily, once daily, or on alternating days based on tolerability. After cleansing, apply liberally onto cotton or into palms and apply to face; massage until absorbed.

Follow with Eighth Day Regenerative Serum. Pour one pipette-length of serum on to fingertip and smooth onto face, neck, and decollete. Avoid eye contact.
