I've used it up, but I don't feel like it's helped prevent age spots from appearing on its own! In addition to this, I was also using UV protection and taking supplements containing L-cysteine, so I barely had any age spots in the summer of 2024. It might be a good idea to incorporate it as one of my age spot prevention measures. Since I have dry skin, the lotion and this serum alone weren't enough, so I need to use a lotion or cream.
It's a gel with a smooth texture. It spreads easily and isn't sticky. It comes in a pump type, so it's hygienic. It has a high moisturizing effect, so I apply it before going to bed. It's alcohol-free, so it's safe.
Keshimin Keshimin Serum 30ml ¥1,408 (tax included) It's amazing to be able to erase blemishes at such a low price! \Without blemishes, skin would be even better! / (1) Vitamin C derivative* breaks down the source of blemishes. (2) Double support moisturizing care. Alpinia White*1 Hyaluronic acid replenishes moisture deep into the skin*1, giving it a moist, translucent look. *1 Deep into the stratum corneum* L-ascorbic acid 2-glucoside*1 Alpinia Katsumadai Seed Extract (quoted from the official website). I bought this because I'm prone to acne and was concerned about acne scars. I've been using other products from Kobayashi Pharmaceutical and I'm a big fan of theirs, so I was hoping that a skincare product at this price would erase my acne scars... Honestly, I didn't see much effect, so I haven't repurchased this product yet. If you have any recommendations for skincare products that work on acne scars, please let me know. ♀♀ #Kesshimin #Serum #Affordable #Connectingwithpeoplewholikebeauty #Connectingwithpeoplewholikecosmetics #Connectingwithpeoplewholikesskincare
