The Science of Stability: Our LUSTRA 10% Vitamin C Serum is a Game-Changer

Vitamin C is a gold-standard ingredient in skincare, but it comes with a significant challenge: instability. Traditional L-Ascorbic Acid serums are notoriously prone to oxidation, turning brown and losing their effectiveness. The LUSTRA 10% Whitening Vitamin C Serum was engineered to solve this exact problem.

The Problem with Traditional Serums

• Oxidation: They lose potency quickly, meaning you're not getting the benefits you paid for.
• Irritation: They require a very low, acidic pH to remain semi-stable, which often causes stinging and sensitivity.

The LUSTRA Solution: In-Skin Bio-Conversion

Our formula's star is 10% Sodium Ascorbyl Phosphate (SAP), a superior Vitamin C derivative that remains perfectly stable in the bottle.

Here's how it delivers its power precisely where it's needed:

1. Application: The stable SAP penetrates the skin's epidermis.
2. Bio-Conversion: Your skin's natural enzymes convert the stable SAP into biologically active L-Ascorbic Acid directly within the skin.

This ensures you receive maximum antioxidant, brightening, and collagen-boosting benefits with every single use, from the first drop to the last.

Key Benefits:

• Potency That Lasts: Guaranteed efficacy throughout the life of the product.
• Superior Gentleness: Formulated at a skin-friendly pH (7.50-8.50), making it suitable for all skin types, including sensitive skin.
• Elegant Formulation: A lightweight, non-sticky water-gel that layers beautifully under moisturizer and sunscreen.
