- SSabrina2 months agoRated 5 out of 5 starsHydrating glow with the prettiest lightweight texture ✨
I’ve genuinely been enjoying this serum both morning and night lately. The texture feels lightweight, silky, and very comfortable on the skin without feeling sticky or heavy at all. It layers beautifully with the rest of my routine and gives my skin a really fresh, healthy-looking glow almost immediately.
One of my favorite things about this serum is how elegant and calming the overall experience feels – from the soft floral scent to the way the formula melts into the skin so smoothly. My skin has been looking more hydrated, more radiant, and overall more refreshed.
I also love how well it works under moisturizer and makeup without pilling. It gives that soft dewy finish while still feeling breathable and gentle on sensitive skin days.
Definitely became one of those products I naturally keep reaching for in my routine

This product felt a little bit harsh on my skin at first. I have very sensitive skin though and the sensitivity went away after continued use.
After continued use this product helps to reduce the look of dark spots and uneven tone to give you a clearer complexion.
Targets dark spots, pigmentation, and post-blemish marks while staying gentle and improving radiance and texture.
I have been using this in tandem with the wrinkle patches for weeks now and I would recommend not using it if your skin is feeling sensitive, but otherwise it does exactly what it says.

I have a little cheat code for good skin ✨ Thanks to attending the Kbeautylayover event last year, I got to try this duo before. And honestly… for any girl dealing with those stupid dark spots, annoying blemish marks, or stubborn pigmentation, this combo is basically a must-have
I start with the ISOI Brightening Serum. It’s not an instant glow product, but it builds that clean, even radiance over time. It absorbs so nicely and helps keep my skin looking clearer and more balanced in the long run and#*****;
