There is no exact dupe for Caudalie Instant Firming Retinol Alternative Serum. The nearest formula is La Roche-Posay Pure Vitamin C Face Serum (59% match), which shares 4 of the original's 8 key ingredients (including Acetyl dipeptide-1 cetyl ester, Adenosine and Hydrolyzed hyaluronic acid).
Match % combines shared ingredients, the first five ingredients, shared actives and hero ingredients, irritancy (lower counts in the alternative's favour), texture and body area. Only products in the same routine step are compared.
