If you are comfortable with your retinoid routine and are ready for more, MASTER SWITCH Progressive 5% HPR Retinoid Serum is an advanced retinoid serum designed to deliver next level results. 

It’s about the right things:

• 5% HPR Retinoid Complex - more than double HPR retinoid than our NEW BEGINNING serum to power up skin renewal and help smooth fine lines, even skin texture, and boost glow.
• 4D Hyaluronic Acid delivers multi-level hydration to keep skin plump and bouncy
• Bakuchiol + Bisabolol, natural plant extracts to restore skin radiance and soothe the skin barrier
• Tranexamic acid to brighten and protect while supporting a more even skin tone

This all in one, multi benefit serum is designed for those who have already built tolerance to gentler retinoids (like NEW BEGINNING Gentle 2% Retinoid Serum) and are ready to take the next step in skin renewal.
