Hyper Vitamin C23 Serum
I did not notice any obvious serum action (pigment lightening). Serum is a bit thick substance and also feels sticky
Its my first time using it and in 2 weeks i feel my skin so much brighter and pretty :)
Makes you look very shiny and causes ur moisturizer to melt…
My skin has such a beautiful glow and has helped with fine lines and some acne
Hyper Vitamin C23 Serum
Feels nice on the skin. Haven't used long enough to observe significant change in skin.
Nice product
Lovely so far. Been using it for a few weeks.
Received an already oxidised bottle and gave me new breakouts unfortunately
Having incorporated vitamin C (10%) into my skincare routine for a few years, I was on the hunt for a potent serum with a higher concentration. While Isntree's C23 serum initially provided a lovely glow and was easily absorbed by my skin, I unfortunately experienced a painful breakout with each use and I don't typically struggle with pimples or acne. Despite my hopeful expectations, this particular product didn't work out for me. I'm currently planning to give either Cosrx C23 a shot or opt for a more gentle approach with Jumiso, avoiding high concentrations.
