LUMI C SERUM

A Brightening Antioxidant Serum for Clear, Even & Radiant Skin

The Cosmetii Lumi C Serum 15% is a lightweight, barrier-supportive antioxidant treatment designed to brighten the skin, improve tone and protect against environmental damage.

Formulated with Sodium Ascorbyl Phosphate (a stable, acne-safe form of Vitamin C) and Australian native fruit extracts, this serum works to support collagen production, reduce inflammation and promote a clearer, more radiant complexion.

Unlike traditional Vitamin C serums that can be irritating or unstable, this formula delivers gentle, consistent results, making it suitable for even sensitive or breakout-prone skin.

The result is skin that appears brighter, more even and visibly healthier over time.

WHAT IT DOES

The Lumi C Serum is designed to brighten, protect and refine the skin.

It helps to:

• Improve overall skin tone and brightness
• Support collagen production and skin firmness
• Reduce the appearance of pigmentation and uneven tone
• Calm inflammation and redness
• Protect against environmental stress and free radical damage
• Support clearer, healthier-looking skin

WHY THIS FORM OF VITAMIN C IS DIFFERENT

Not all Vitamin C is created equal.

This formula uses Sodium Ascorbyl Phosphate, which is:

✔ More stable than traditional Vitamin C
✔ Less irritating on the skin
✔ Suitable for acne-prone and sensitive skin
✔ Proven to support both brightening and breakouts

This allows for consistent results without compromising the skin barrier.
