It's an exellent product.My dermatologíst recommended it to me because I had a breakout of pimples.To get rid of the blemishes,I've only Been using it for two days ,but my skin already feels Softer and brighter.

Es excelente por su eficacia y suavidad para la piel porque no me ha causado irritación ni rojez, es un serum ligero y de rápida absorción y no deja la sensación pegajosa y ha sido bueno para mí que tengo la piel grasosa

I’ve been using the Sesderma Reti-Age Antiaging Serum for several weeks and I’m really impressed. The texture is lightweight, absorbs quickly, and doesn’t leave a sticky feeling. My skin feels firmer, hydrated, and looks healthier overall. It didn’t cause any irritation, even when used at night, and the scent is very mild and pleasant. I love how my skin looks in the morning—smoother, brighter, and more refreshed. I would definitely continue using this serum as part of my anti-aging routine.
