I got this one for the daily use and loved it. Once it finished I ordered the 7500 one and use it once/twice a week. It helps with skin tone, moisturizing, post acne.
I have done my own research and created a skincare regimen to both combat old hormonal hyper-pigmentation which I've been struggling with for years. Ive been using this products 3 times a week and and have definitely noticed the edges of my dark spots becoming less dark prominent.
Honestly, not overwhelmed by this product. It just feels like a milky serum. I didn't notice any difference in my skin after using it for a few weeks.
