O2 Serum
Oxygenate, energize, and glow. O2 Serum — nicknamed the Bubble Serum — delivers a unique oxygenating experience powered by Methyl Perfluoroisobutyl Ether, which helps deliver oxygen into the skin for a visibly energized, radiant appearance. The subtle effervescence on contact signals active penetration at work.
Loaded with humectants, peptides, traditional Korean botanicals, caviar extract, and ginseng, this featherlight serum hydrates, brightens, firms, and soothes — ideal for skin that looks dull, fatigued, or depleted.
Why It Works
- Instantly energizes tired-looking skin — The oxygen infusion in the formula helps awaken the appearance of fatigued skin and revitalize natural radiance.
- Boosts radiance with caviar extract & ginseng — These active ingredients support a more luminous, even-looking complexion.
- Supports the look of firmness with copper peptides — Copper peptides help support a collagen-rich appearance for firmer-looking skin.
- Featherlight texture — Absorbs quickly with no residue.
- Layers easily — Ideal as a prep serum to enhance the layering of subsequent products.
How to Use
Apply 1–2 pumps to clean, dry skin after toner or essence. Gently press into face and neck until absorbed. Use morning and/or evening. Follow with moisturizer or cream. Safe for layering with other active treatments like niacinamide or peptides.
