Why it's a dupe
- Both are cleansers.
We found no close formula dupe for Byphasse Anti-Imperfection Clay Mask. The nearest product, ULTA Detoxifying Charcoal Deep Cleansing Clay Mask, is only a 36% match: it shares 4 of the original's 10 key ingredients (including Kaolin, Stearic acid and Cetearyl alcohol).
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.
