Thalgo Source Marine Intense Moisture Quenching Serum 30ml

The first universal radiance serum by Thalgo that targets the loss of luminosity at its source. Lumisource works to reactivate the natural detoxification process while Skin-Protect delays the production of oxidised proteins that cause a dull complexion. This genius formulation delivers pure radiance and a unique glow to the complexion.
