Holiday countdown season is officially here, and the latest skincare calendar to land is the Biossance 10 Days of Wonder Advent Calendar 2026. This limited-edition set packs ten days of the brand's squalane-powered bestsellers, mixing travel and full sizes, into a teal book-style box with holographic foil inspired by the Northern Lights. It's up for pre-order now, so here's everything you need to know about the release date, products and price.
Price and Value
The calendar costs $99, while Biossance puts the value of the contents if bought separately at $216, which the brand says is a saving of $117 (54% off). Biossance doesn't publish an item-by-item breakdown for the travel sizes, so that $216 figure is the brand's own.

Why It's Worth Unwrapping
Biossance describes the set as a curated lineup that runs "from powerful hydration to visible plumping," and the brand-reported results back that up:
- Omega Repair Cream: 100% showed improved skin hydration five minutes after use (clinical study, 35 women)
- Copper Peptide Rapid Plumping Serum: 97% noticed improved firmness and elasticity after one week (consumer study, 31 women)
- Ectoin Overnight Rescue: 97% saw reduced irritation and dryness after four weeks (28-day consumer study, 33 women)
- Firm and Lift Dual Serum: 92% agreed it was immediately effective on fine lines (questionnaires, 24 subjects)
- Vitamin C Rose Oil: 91% agreed skin had a healthy radiant glow (21-day consumer study, 32 women)
There are accolades too. The Marine Algae Eye Cream, Omega Repair Cream and Ectoin Overnight Rescue are accepted by the National Eczema Association, which is good news for sensitive skin. Vitamin C Rose Oil is an Allure and Glamour Readers' Choice winner, and the Lip Perfector won Allure Best of Clean Skincare 2025.
How to Use Your Calendar Finds
Build a simple routine as you open each door:
- Cleanse: Work 1–2 pumps of the Amino Aloe cleanser into a lather and massage it onto damp skin for 30 seconds.
- Treat: Shake the Firm and Lift Dual Serum to activate it, or press in a dropper of the Copper Peptide serum.
- Eyes: Use the niacinamide serum's rolling applicator in outward motions, then tap on the Marine Algae Eye Cream with your ring finger.
- Night: Finish with Ectoin Overnight Rescue, which is formulated for nighttime use.
- Glow: Press a few drops of Vitamin C Rose Oil onto clean skin.
Keep the Lip Perfector in your bag. It works on its own or layered over matte lipstick.
