SUMSAE Vitamin C Serum 10.5% Waterless – Airless Pump Brightening & Firming, 30ml

Formulated in Korea and engineered to lock in potency, this serum uses a triple-barrier system to protect active vitamin C without added water. The oil-gel matrix and lipid-coated droplets sit in a propanediol base so the ascorbic acid remains stable until applied, while adenosine, panthenol, and beta-glucan help maintain skin comfort and barrier resilience.

How does the waterless, no-oxidation formula keep vitamin C effective?

The serum removes water and isolates vitamin C inside protective structures, slowing degradation that normally happens when vitamin C contacts air and aqueous solutions. An airless pump and sealed triple-barrier delivery reduce exposure to oxygen and moisture from the first drop to the last.

• 10.5% pure vitamin C in a low-water vehicle to limit hydrolysis.
• Lipid-coated droplets that shield active molecules from oxygen.
• Oil-gel matrix to stabilize consistency and slow breakdown.
• Special airless pump prevents air ingress during use.

What skin changes can I expect and when might they appear?

With consistent application, many users notice reduced dullness and improved skin tone within a few weeks as pigment appears less pronounced and skin reflects light more evenly. The formula is also designed to support a firmer-looking complexion by addressing texture and elasticity cues over time.

• Brighter-looking complexion and reduced dullness with regular use.
• Smoother texture and more even tone visible after several weeks.
• Supportive ingredients like adenosine for appearance of skin firmness.
• Hydration-supporting panthenol and beta-glucan to comfort the skin.

How should I add this serum to my routine safely?

Apply the serum to clean, dry skin once or twice daily depending on tolerance, then follow with moisturizer and sunscreen in the morning. Start with a patch test if you have sensitive skin, and introduce gradually to monitor how your skin responds to an active vitamin C level.

• Use on cleansed face, morning or evening.
• Follow with moisturizer; use SPF during daytime routines.
• Patch test before full-face application if sensitivity is a concern.
• Store upright in a cool, dry place to preserve formula integrity.

What packaging and delivery features ensure freshness?

The product arrives in an airless dispenser and uses a multi-layer protective system that minimizes oxidation and preserves concentration throughout the bottle’s life. The packaging design pairs with the waterless formulation to reduce common causes of degradation for vitamin C serums.

• Airless pump prevents air exposure during every dispense.
• Triple-barrier protection: propanediol base, lipid-coated droplets, oil-gel matrix.
• 30 ml (1.01 fl. oz) size for a concentrated course of use.
• Opaque components help block light that can accelerate breakdown.

Who this is for: SUMSAE Pure Vitamin C Serum suits anyone seeking a targeted brightening and firming boost from a stable, waterless vitamin C formula — especially those who want a long-lasting product protected from oxidation. It’s a good choice for people comfortable introducing a concentrated active into their regimen, and for users wanting supportive ingredients like adenosine, panthenol, and beta-glucan to help maintain skin comfort and barrier resilience.
