Este sérum es muy apreciado por su capacidad para iluminar y unificar la piel apagada, mejorando el aspecto general y suavizando las líneas de expresión. Su textura ligera y acuosa se absorbe rápidamente, por lo que es un gran complemento para las rutinas de cuidado de la piel, especialmente para pieles grasas o sensibles, sin causar irritación. Sin embargo, el sérum tiene un olor fuerte y característico que algunos describen como metálico o similar al del café, aunque suele desaparecer rápidamente. Los usuarios también deben tener en cuenta que requiere refrigeración para evitar la oxidación y mantener su eficacia.
Really lovely, good for evening dark spots and creating a glow. You have to keep it in the fridge and it does stink. If your skin can tolerate it, I’d definitely go up to 23%. Best to use at night, as it does react with moisturiser (not in a painful way), meaning you can get orange tide marks.
The COSRX Pure Vitamin C 23% Serum has quickly become one of my favorite brightening serums. It’s strong enough to make a visible difference in dullness, uneven skin tone, and fine lines, yet the formula feels balanced thanks to the addition of vitamin E and hyaluronic acid.I noticed my skin looking fresher and more radiant within a few weeks, and with consistent use, my complexion feels smoother and more even. The texture is lightweight, absorbs well, and doesn’t leave a heavy or sticky finish.If you’re looking for a powerful yet hydrating Vitamin C serum, this one really delivers. Just remember, like with all skincare, patience and consistency are key to seeing lasting results.
This is my 4th bottle and the most gentle vitamin C serum I have ever use. Suitable for sensitive skin. Noticeable effect after using second bottle.
Ok
