Review of the recently used Vitsi serum.
Cosrx The Vitamin C 23 ⭐
Give Whitsea 23%.
Personally used, not allergic. Not burning.
But the face is very fast and oxidizes.
Must keep well from being exposed to light and heat
It should be used up in a month.
Isdin Flavo-C ⭐
The brand claims it's effective, stays on the skin for up to 8 hours.
Use 3 drops at a time. Not as light as water, but not as heavy or sticky.
No problem oxidizing as fast as Cosrx.
But since it's Vit c, it's best to use it up within 2 months.
Personally use Vit C because
- Enhancing the effectiveness of sunscreen.
- Stimulate collagen formation.
And the dark spots don't care much. The focus is more on protecting old skin.
