ROUGJ+ Smartfiller Botulinum-Like Effect Serum Soft and velvety serum that, thanks to the presence of argireline in the formula, instantly prevents and reduces wrinkles in the eye contour area. Just a few moments after application, it fills and refines expression lines, relaxing facial features with a tensor effect for up to 6 hours. It can be applied in two ways: as a serum, before your usual moisturizer, to better convey the active ingredients contained in the cream; after make-up to obtain a botulinum-like effect. The light texture is quickly absorbed without leaving a trace, giving the face a more relaxed appearance. How to use: Apply the serum before your usual moisturizer, to better hydrate and convey the active ingredients contained in the cream, or as a final step after make-up, to obtain a botulinum-like effect lasting up to 6 hours.
