I'm still in my 30s, but when I was in my teens and 20s, tanning was my hobby, and I ended up with a lot of age spots as a result of that time.
I am using this product because I want to do something about it because just having age spots can make my skin look much older.
I use it partially on the stains I'm concerned about, but the stains don't disappear right away.
If you keep using it for a long time, the stain will gradually become lighter, so I use it every day without fail.
I've been using it for about 2 months, but it's gradually become less noticeable.
The key is to continue using it for a long time.
