Vitamin C 18% Booster Serum

Pure L-Ascorbic Acid for Radiance, Resilience & Defense

A high-performance Vitamin C serum formulated with 18% pure L-ascorbic acid, the most biologically active and effective form of vitamin C for the skin. This advanced antioxidant treatment is designed to visibly brighten, smooth, and strengthen the skin while defending against environmental stressors that accelerate visible aging.

Lightweight, fast-absorbing, and barrier-supportive, this formula delivers clinical-level performance without unnecessary irritation.

It doesn’t just improve how your skin looks.
It supports how your skin functions.

Why Your Skin Needs Vitamin C Every Day

Your skin is exposed to oxidative stress constantly—from sunlight, pollution, inflammation, and daily environmental triggers. Over time, this damage weakens collagen, slows repair, and accelerates visible aging.

Vitamin C is one of the most essential protective nutrients in skincare.

When used consistently, it helps:

• Support collagen production

• Brighten dull skin

• Improve uneven tone

• Strengthen skin resilience

• Reduce visible signs of aging

• Defend against environmental damage

This is why vitamin C is considered a cornerstone of functional skin restoration, not just cosmetic improvement.

Key Benefits

• Visibly improves skin brightness and radiance

• Helps reduce the appearance of fine lines and wrinkles

• Supports firmer-looking, more elastic skin

• Helps improve uneven tone and discoloration

• Smooths skin texture and refines appearance

• Provides antioxidant defense against pollution and free radicals

• Supports clearer-looking, calmer skin

• Helps strengthen the skin barrier

What Makes This Vitamin C Serum Different

Not all vitamin C is created equal.

Many formulas use vitamin C derivatives that require conversion in the skin and often deliver limited activity.

This formula uses pure L-ascorbic acid—the gold standard form supported by dermatological research.

It is:

• Biologically active immediately

• Highly effective for collagen support

• Proven to brighten and protect skin

• Clinically recognized for antioxidant defense

Why This Formula Works

Vitamin C (L-Ascorbic Acid – 18%)

The most effective form of vitamin C for the skin.

Supports:

• Collagen production

• Skin brightness

• Antioxidant protection

• Improved skin tone

• Barrier resilience

The 18% concentration falls within the clinically effective range for visible results.

Glutathione — The Master Antioxidant

Helps support:

• Skin clarity

• Brightness

• Detoxification processes

• Protection against oxidative stress

Works synergistically with vitamin C to enhance overall skin defense.

Ferulic Acid + Vitamin E — Stability & Performance

This clinically recognized antioxidant combination:

• Enhances vitamin C stability

• Extends antioxidant activity

• Protects against environmental damage

• Supports healthier-looking skin

These ingredients significantly improve the effectiveness of vitamin C.

Vitamin A (Beta-Carotene & Retinyl Palmitate)

Supports:

• Skin renewal

• Texture refinement

• Collagen support

• Smoother appearance

Helps maintain healthy skin turnover.

Mineral & Skin-Support Complex

Zinc, calcium, magnesium, glucosamine, and MSM help:

• Strengthen barrier function

• Support hydration balance

• Improve skin resilience

• Reduce inflammation

• Promote overall skin health

Healthy skin requires structural support—not just surface treatment.

Why L-Ascorbic Acid Matters

Many vitamin C products contain:

• Sodium ascorbyl phosphate

• Magnesium ascorbyl phosphate

• Ascorbyl glucoside

• Vitamin C esters

These forms must convert inside the skin before becoming active.

Conversion is often inefficient.

Pure L-ascorbic acid works immediately.

That difference determines results.

What to Look for in a True Vitamin C Serum

A high-performance formula should include:

✔ L-Ascorbic Acid (10–20%)
✔ Vitamin E + Ferulic Acid
✔ Air-tight, light-protected packaging

This formula meets all three criteria.

Who This Product Is For

This Vitamin C serum is ideal for:

• Dull or tired-looking skin

• Uneven tone or discoloration

• Fine lines and early signs of aging

• Environmentally stressed skin

• Hyperpigmentation or sun damage

• Acne-prone or redness-prone skin

• Sensitive skin (when introduced gradually)

• All skin types seeking antioxidant protection

How to Use

Consistency produces the best results.

How This Fits Into Your Routine
