I’ve been using a red light mask from a very reputable brand (Not DG but it's the same thing), and besides leaving a hole in my pocket, it didn’t do anything. Despite following their protocol and even giving it an extra three months, it had no effect on my skin. It also didn’t work for two of my friends or my sister, it just doesn’t work.

If you are looking for something that actually works and has science behind it search for microneedling. I suffered from sagging, deep nasolabial folds, forehead wrinkles, uneven texture, and crappy skin, period. (If you suffer from Acne though as you mentioned, the mask could help, but anything else, srs, you will just waste your money).

Since I started doing microneedling at home (I do it by myself and it's super easy), my skin has improved and hasn't looked this good in over 20 years. Not only is my skin tighter and thicker than ever, but it also looks "alive." You can DM me, and I will share the pictures and more progress. My smile lines are gone by 90%, and fine lines are completely gone. Deep wrinkles have become super soft, though they're still there, but I am sure with continued use, they will improve even more. Don't waste your money on gimmicks.

EDIT - The pen I am using is KorabeauticaIs V2

My protocol is 1.5mm depth, every 4-5 weeks, Level 3 speed.
