How to Use

Simplicity is key. Use this as the very first step in your routine after cleansing.

1. After cleansing your face, dispense 2-3 pumps into your palms.
2. Gently pat the booster onto your entire face and neck until fully absorbed.
3. Follow with your usual serum, moisturizer, and SPF (in the AM).

Expert Tips: Supercharge Your Routine

The 6 Peptide Skin Booster is the ultimate team player. It’s designed to enhance the effects of your other active ingredients.

• Pair with Vitamin C: Use the peptide booster first in the morning to support your skin barrier, then apply your Vitamin C for amplified antioxidant protection and brightening.
• Pair with Retinol: At night, apply the booster before your retinol. The peptides help soothe the skin and support collagen production, making your retinol work more effectively with less irritation.
• Pair with Niacinamide or Hyaluronic Acid: Layer with your favorite serums to double down on pore-refining, brightening, and hydrating benefits.
