I do like Mimi Von Snatch, she gives good advice and is real with her routine. I also like her skin tone.
About a year and a half ago, I decided to lighten my skin ( I was already quite fair but I was always unsure about going all the way) and Mimi von snatch and May skincare on youtube were the people I used to kinda lead my skincare routine. Also, I did get a lady mixologist but the difference this time was before she mixed/whilst mixing we had a sit down to analyse my skin type and we worked with products that have worked for me in the past to create a mix and that was when I began seeing a massive difference in my skin tone. Another thing was the mix was not a strong mix and this paired with a routine of exfoliation and also taking rest days, one would never ever believe that I was never as light as this 2 years ago.
Another thing I also know is that yes, gluta IV works but it works slowly and over a long period of time. This I know because the lady who mixed my lotions explained and broke it down to me. She explained that yes, the IV takes but almost all the light-skinned girls who use IV also follow up with supplements, strong skin-lightening products, spa sessions, full body scrubs etc and that's when they usually go from one shade to like 4 shades lighter. She told me it costs a fortune to go down that route, the results can be very drastic but they work really well.
I don't want drastic, I want steady hence the lotion route and rest days in between. This is about all I know.
All those influencers definitely do a lot more than we know.
