Review: very potent, no smell - This stuff is actually pretty strong as it is 24% vitamin C. I highly recommend using a little bit on the first few times otherwise it may be too much for your skin. I didn't realize the potency of this no wonder on my first day it hurt a little when I applied this on my face. It wasn't painful stinging but I could feel my skin reacting with a little bit of stinging. Make sure to use this stuff with sunscreen (daytime) otherwise your skin may burn from the sensitivity of this vitamin C. I usually put this on at night and in the daytime I make sure to have sunscreen on and try to stay in the shade and out of the sun. I think this is very reasonably priced considering the concentration. It is 20 mL, a small dropper bottle, but you don't need a whole lot so this bottle should last a while. It didn't have any awful smell like some vitamin C products have, I don't think I smelled anything. So far it is too soon to tell if this helps with any of my age spots but for something with this amount of vitamin C concentration I don't see why not. This product is made in Korea. The expiration date is clearly printed on the bottom of the bottle.
Review: Maximum vitamin C without drying or irritation - I’m a longtime user of vitamin c serums and ascorbic acid is my favorite form of it. I feel like it has the best brightening capabilities. This formula is really high potency (23%) and I personally haven’t seen higher. This form and concentration normally leaves the skin feeling a bit dry but this serum seems to have been strategically formulated to counteract that dryness. I experienced no irritation or stinging from this high concentration. In fact my skin felt quite soothed and hydrated. I’m impressed by this formulation. Also, it comes in an opaque bottle to prevent oxidizing. I didn’t see the ingredients listed, so providing them below for those who are curious: Water, Ascorbic Acid (23%), Propanediol, Betaine, 1,2-Hexanediol, Polyglycerin-3, Tromethamine, Ethyl Ascorbyl Ether, Hydroxyethyl Urea, Betula Platyphylla Japonica Juice, Ethylhexylglycerin, Adenosine, Disodium EDTA, Panthenol, Gardenia Florida Fruit Extract, Dextrin, Tocopherol

### ⭐⭐⭐⭐ Very Strong Vitamin C Serum – Not for Beginners
*by K***S on August 13, 2023*

This is a very strong vitamin C serum (23%) & not for beginners. I apply Vitamin C serum almost every day & this one is borderline too much for my skin. It stings a bit & did irritate my skin a bit. This is one you definitely need to work up to & even then, should use only a few times a week, at most. I like that is has no added perfume. It absorbs well. It comes in a dark bottle which is good. Vitamin C is easily damaged by light/heat/air.
