I've used this at night for 30 days. I didn't do a before/after, but I can honestly say that when my kid took a picture of me the other day, it looked like he added a filter. Literally my skin looks RIDICULOUSLY better. I'm 40. I grew up a beach baby and live in Las Vegas now... I'm in the sun daily. I swear on 37 Bibles that this stuff has easily taken off 10 years from my face. Literally.I use probably 1/2 - 3/4 of the dropper, definitely not just a couple drops. It could be because it is SO dry here. After applying this, I use black seed oil to moisturize. That's my sum total of skin care. I'm sold for life.
