A lightweight, peptide-infused serum that firms, hydrates, and preps skin to better absorb the rest of your routine.

Why It's Special

Skin Concerns: Targets anti-aging, dryness & dehydration, fine lines & wrinkles, loss of firmness, and uneven texture.

Key Features: Brightening, firming & lifting, hydrating, and strengthening.

Clean Formula: Alcohol-free, artificial fragrance-free, paraben-free, and sulfate-free.

Skin Type & Texture: A lightweight serum suitable for all skin types.

A Deeper Look

This multitasking booster is your first step to a revitalized complexion. Infused with six concentrated peptides, sodium hyaluronate, and amino acids, it works to visibly lift sagging areas, smooth uneven texture, and deliver a surge of hydration. More than just a serum, it acts as a powerful prep step, enhancing your skin's ability to absorb and benefit from every product that follows. The result is a noticeably firmer, more radiant, and plump look that feels as good as it appears.

How to Use

After cleansing, apply an appropriate amount to your face as the first step of your routine. Gently pat until absorbed. Follow with your next serum or ampoule.
