Amazing and potent
I will fully admit to being nervous about trying this one. 23% Vit C was more than I have used, ever.
There was no need for worry. I’ve been using this nightly, & already seeing wonderful results. I store it in a cool place, follow all directions on the packaging. I was so impressed with the care taken in this packaging & in the detailed directions enclosed. Thank you Cosrx. That gave me comfort.
I feel a slight tingle when I apply this sometimes (more so if I have exfoliated recently), it goes away quickly, & I’m left with a slight warmth on my skin. They truly were able to deliver a high potency Vitamin C serum, that does not have a negative effect on my skin. Much lighter weight than I expected, & absorbs so quickly. I started with just a couple drops, but have worked up to about 5 drops & no oily feeling at all.
