What the brand claims
In the brand’s own words, quoted as written.
“Clinically tested to deliver thicker, fuller, and stronger lashes in just four weeks, Wonder'serum is a salon-inspired revitalising serum formulated with a nutrient-rich blend of vitamins, proteins, and peptides. Infused with bamboo extract and castor oil, it helps strengthen lashes, reduce breakage, and protect against fallout when applied daily along the lash line or sparse brows.”
