Guerniss Raw Glutathione Vitamin C Serum 30ml (Bangladesh)

The Guerniss Raw Glutathione + Vitamin C Serum (30ml) is your ultimate "morning glow" specialist. While the other serums in the Raw series focus on hydration (Hyaluronic) or texture (Niacinamide), this one is specifically formulated for intense brightening and environmental protection.

By combining two of the most powerful antioxidants in the skincare world, this serum acts like a shield for your face throughout the day.

The Brightening Duo: Key Ingredients

Glutathione: Known as the "Master Antioxidant," it works to brighten the skin by inhibiting melanin production and reducing the oxidative stress that leads to dullness.

Vitamin C (L-Ascorbic Acid or derivatives): The gold standard for radiance. It helps fade dark spots, boosts collagen production, and protects your skin cells from damage caused by UV rays and pollution.

Main Benefits

Instant Radiance: Gives the skin a noticeable "lit-from-within" glow shortly after application.

Sun Damage Defense: When worn under sunscreen, Vitamin C actually makes your SPF more effective at fighting free radicals.

Fades Dark Spots: Highly effective at lightening post-acne marks (PIH) and sun-induced freckles.

Anti-Aging: Stimulates collagen to help keep skin firm and reduce the appearance of fine lines.

How to Use for Maximum Brightening

Morning Priority: While it can be used at night, this serum is best used in the morning (AM) to take advantage of its protective antioxidant properties.

Cleanse & Tone: Apply 2–3 drops to a clean, dry face.

Wait for Absorption: Let it sink in for about 30 seconds before layering other products.

The "Must-Have" Finish: Always follow with Sunscreen. Vitamin C and Sunscreen are best friends; they work together to prevent new dark spots from forming.

Pro-Tips for Vitamin C

Storage Matters: Vitamin C can "oxidize" (turn orange/brown and lose its power) when exposed to air and light. Keep the bottle tightly closed in a cool, dark place.

Avoid the "Clash": Do not use this in the same application as the Glycolic Acid or Salicylic Acid serums you mentioned earlier. Use the acids at night and this Vitamin C serum in the morning to avoid irritating your skin.
