Brighten, calm, and firm in one powerhouse step.

Circadia Serum 71 is a multitasking formula designed to target stubborn pigmentation, refine skin texture, and improve elasticity—all while keeping inflammation in check. This lightweight serum blends 2% tranexamic acid, 5% mandelic acid, and 0.3% azelaic acid to correct and prevent dark spots, breakouts, and redness without compromising sensitive skin.

What makes Serum 71 truly special is its inclusion of Neodermyl®, a next-gen copper peptide known to stimulate the skin’s natural production of collagen and elastin, visibly improving skin firmness and density. Antioxidant-rich and mildly exfoliating, this formula promotes a clear, even-toned glow with zero harshness.

• Visibly brightens and fades discoloration
• Prevents and calms breakouts and inflammation
• Restores firmness by stimulating collagen and elastin
• Gentle exfoliation without irritation

We love pairing Serum 71 with Circadia’s Licorice & Bearberry Brightening Mist for a double dose of pigment-fighting power. It’s also a favorite for those looking to tackle both breakouts and uneven tone without drying out the skin.

After cleansing and toning apply a few drops to face, neck, and chest in the evening, layer with your favorite moisturizer. Always be sure to apply SPF in the AM when using this product.
