Ce sérum est très apprécié pour sa capacité à illuminer et à unifier les peaux ternes, améliorant l'aspect général et lissant les ridules. Sa texture fluide et légère pénètre rapidement, ce qui en fait un excellent complément aux routines de soin, en particulier pour les peaux grasses ou sensibles, sans provoquer d'irritation. Cependant, le sérum dégage une odeur forte et distincte que certains qualifient de métallique ou de semblable à celle du café, bien qu'elle s'estompe généralement vite. Les utilisateurs doivent également noter qu'il doit être conservé au réfrigérateur pour éviter l'oxydation et préserver son efficacité.
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
