Why it fits
Exfoliating acids call for daily sun protection, so a mineral SPF every morning protects the brighter, more even look this serum works on overnight.

Circadia Serum 71
Circadia Serum 71 is an evening serum for skin that looks uneven, dull or prone to blemishes. It brings together three acids to gently exfoliate and visibly brighten: mandelic acid (5%), tranexamic acid (2%) and azelaic acid (0.3%).
Together they help reduce the look of discoloration, redness and blemishes, for skin that looks clearer and more even. CM-Glucan Forte helps support and comfort the skin barrier, and NeoDermyl® (copper lysinate/prolinate) helps support the look of firmer, denser, more resilient skin.
Because it contains exfoliating acids, wear a daily sunscreen while you use it.
Why we love it
Some skin looks uneven and tired but does not tolerate stronger exfoliants. Serum 71 is our answer for it: three acids working gently every evening, with barrier support built in. Used steadily, with sunscreen every morning, it lets tone look more even without putting your skin through a harsh reset.
Benefits
- Helps reduce the look of discoloration, redness and blemishes
- Gently resurfaces and visibly brightens without irritation
- Helps support a stronger, more resilient skin barrier
- Helps support the look of firmness and density
- Leaves skin looking clearer and more even
