It moisturized and brightened my skin! I haven't noticed any tightening. Because it is gentle on the skin, no peeling occurred. When applying Vitamin C to your skin, remember to use sunblock or sunscreen as well because Vitamin C makes your skin more sensitive to the sun. AND IT IS SUITABLE FOR ALL SKIN TYPES! However, if you have sensitive skin, limit your use to once per day.
Because Hello Glow AHA Bright Booster Serum contains active ingredients, there is a high possibility you will experience purging.
Purging was an issue for me for the first 1-3 weeks. But, no more zits appeared on my skin after that!
