What is Vitamin C Serum & Why Should You Use It?
Vitamin C serum is a potent antioxidant formulated to brighten skin, fade hyper pigmentation, and boost collagen. Unlike moisturizers, serums contain higher concentrations of active ingredients, allowing deeper penetration.
Key Benefits of Vitamin C Serum
✔ Brightens Skin – Reduces dullness for a **healthy glow**
✔ Fades Dark Spots – Targets melasma, sunspots, and acne scars
✔ Anti-Aging Powerhouse – Stimulates collagen, reducing fine lines
✔ Sun Damage Protection – Neutralizes free radicals from UV exposure
✔ Reduces Inflammation – Helps with acne and redness
(Pro Tip: Look for L-ascorbic acid (15-20%) for maximum potency, or gentler derivatives like SAP or MAP for sensitive skin.)
