Category: Antioxidant / Anti-Aging

What It Is: A lipid-soluble antioxidant naturally produced by the body and found within every cell — where it plays a central role in cellular energy production. As we age, CoQ10 levels in skin decline significantly, reducing the skin's ability to repair itself and resist oxidative damage. Topical Ubiquinone replenishes this deficit directly at the skin level.

How It Works: Neutralizes free radicals at the cellular level, supports mitochondrial function in skin cells, and helps reduce the visible effects of oxidative aging.

Benefits:

• Protects against oxidative cellular damage
• Supports cellular energy and renewal
• Reduces visible signs of aging over time

Category: Brightening / Pigment Correction

What It Is: A clinically validated brightening active that targets hyperpigmentation at its source. Tranexamic Acid works by interrupting the chemical signal between UV-stimulated keratinocytes and melanocytes, effectively reducing melanin overproduction — without the irritation or sensitivity associated with stronger depigmenting agents like hydroquinone.

How It Works: Blocks the signaling pathway that triggers excess melanin production, visibly fading dark spots, post-inflammatory marks, and uneven tone with consistent use.

Benefits:

• Fades dark spots and discoloration
• Evens and clarifies overall skin tone
• Gentle enough for daily and long-term use

Compatibility: Best paired with Niacinamide, Bakuchiol, and daily SPF for full-spectrum brightening support.
