Biossance Squalane + Copper Peptide Rapid Plumping Serum
The house's headline serum: a copper peptide for the look of firmness, carried in a plumping complex of hyaluronic acid, polyglutamic acid and the brand's own squalane.
The serum the house is known by, and the one bottle that shows the whole design: Copper Tripeptide-1 for the look of firmness, a Rapid Plumping Complex that makes skin look full on contact, and the sugarcane squalane base underneath. At 50 ml, fragrance free and EWG Verified on its listing, it is also the easiest Biossance purchase to justify. If the brand gets one chance on your shelf, this is the bottle that should take it.
The specification
- Size

- Format
- Dropper serum, fragrance free
- Key ingredients
- Copper Tripeptide-1, hyaluronic acid, polyglutamic acid, squalane, ectoin
- Use
- Apply to clean face and neck once or twice daily, alone or under other treatments, as directed on the packaging

Strengths
- Copper Tripeptide-1 leads, with Tetrapeptide-30 and Palmitoyl Hexapeptide-52 also named in the published ingredient list
- The Rapid Plumping Complex of hyaluronic acid, polyglutamic acid and sugarcane squalane gives the firming step immediate, visible hydration
- At 50 ml it is nearly double the standard serum volume, and the formula is fragrance free with an EWG Verified mark on the listing
Limitations
- No copper peptide percentage is printed, so the formula asks to be judged on its design rather than a number
- The botanical extract list is long, which strict minimalists may not want in a treatment step
- A dropper on a 50 ml bottle takes a steady hand to dose without waste
What owners report
In praise
- The bouncy, visibly plumped feel straight after application is the theme owners return to most
- Skin looking firmer and smoother with steady twice daily use, especially on dehydrated skin
- Fragrance free, comfortable wear under moisturizer and makeup
With reservations
- Layering it in the wrong order leads to pilling under later products for some owners
- The large bottle still empties faster than expected when the routine includes neck and chest
- Owners who track percentages wish the copper peptide level were printed
Suits

Skip if
