Sérum anti-age

The Mlle Agathe serum's hero active is snail secretion filtrate, which ISANA completely lacks; ISANA is instead a Q10/plant-oil moisturizing serum with only minor overlap (tocopherol, citric acid).

This is an oil- and botanical-based 'multi-oil' serum with no snail secretion filtrate, so it misses the source's signature active despite sharing common base ingredients like tocopherol and lactic acid.

Like the other Swiss Toniq product, this is a plant-oil/botanical hydration serum lacking snail secretion filtrate, the defining active of the source product.

Tula's formula centers on vitamin C derivatives, tranexamic acid, and probiotics for brightening, with no snail secretion filtrate to match the source's core active.

This is a caffeine/peptide eye gel with no snail secretion filtrate and minimal ingredient overlap beyond a trace of tocopherol.
