This thread needs a klaxon!
Here are the listed ingredients:
Aqua, Alcohol Denat, Aloe Barbadensis Extract, Collagen, Glycerin, Butylene Glycol, Canola oil, Cucumis Sativus Extract, Propylene Glycol, Polydextrose, Sodium Lactate, Lactic Acid, Xanthan gum, Glycolic Acid, Methylparaben, Parfum.
Basically the lactic acid and the glycolic acid act as a chemical peel.
The rest is for moisturising, and solution thickening.
