We have had several posts recently on skincare and though I would share this. I recently started using vitamin C serum in the morning and here is what I found out in my research.
This is the one I ended up with. Vitamin C degrades fast, as soon as three months after being exposed to air and the cost of most product is very high so I read a lot. I also found this vlogger that did a test using three different companies.
I am really liking the Timeless skincare and will try some of their other products in the future.
