Description
Gluvit-S Vitamin C Brightening & Lightening Serum — 30ml
Gluvit-S Vitamin C Brightening & Lightening Serum is a high-potency Vitamin C serum by Asra Derm, formulated with a clinically relevant 20% L-Ascorbic Acid, 0.5% Ferulic Acid, and Prebiotics. This is the Vitamin C-focused member of the Gluvit-S family — distinct from the Gluvit-S Brightening Serum (which centres on Arbutin 2% + Glutathione) and the Gluvit-S Brightening Cream (a richer multi-active formula). This serum delivers powerful antioxidant protection, helps brighten and lighten skin tone, and targets dark spots, fine lines, and dullness. Suitable for morning and evening use.

FAQs
How is Gluvit-S Vitamin C Serum different from Gluvit-S Brightening Serum?
This serum is built around 20% L-Ascorbic Acid (pure Vitamin C) + Ferulic Acid for antioxidant brightening, collagen support, and anti-aging. The Gluvit-S Brightening Serum uses Arbutin 2% + Hyaluronic Acid + Glutathione for tone correction and hydration — a different active profile.
How is it different from Gluvit-S Brightening Cream?
This is a lightweight, high-potency Vitamin C serum applied as drops. The Gluvit-S Brightening Cream is a rich cream texture with a multi-active blend including Retinol, Niacinamide, and Zinc PCA.
Why is 20% L-Ascorbic Acid significant?
20% is a high, clinically relevant concentration of pure Vitamin C. Ferulic Acid in the formula stabilises and boosts the vitamin C's effectiveness and stability.
Why must I use sunscreen with this serum?
Vitamin C increases skin sensitivity to UV radiation. Daily broad-spectrum SPF is essential to protect the skin and preserve results.
Can I use this serum in both morning and evening?
Yes, it is suitable for both AM and PM routines. In the morning, always follow with sunscreen.
Do I need to do a patch test?
Yes, especially if your skin is sensitive or you have not used a high-concentration Vitamin C product before. Apply to a small area first and check for any reaction.
