Review (3/5): STOP! PLS READ BEFORE PURCHASE!!
I got this party based on the reviews from Amazon and I should have done more researching I looked up a YouTube tutorial and there was a lot more to this than just microderm in your skin and putting serum on there there's a lot of factors to take into consideration
1. You should get the Derma roller that has titanium needles because with time metal does rust and on this product it has metal
2. Don't use anything higher than a .5mm at home. Anything higher causes bleeding and you would need some sort of anesthesia because it punctures the Skin Deep
3. This .25 can be used every two to three days and they say putting makeup on after is not recommended because your pores are open and you should wait at least 24 to 48 hours
These were the most important tips to me but you should totally go on YouTube and look at tutorials before purchasing
Also you should get the most expensive one I should have known better than to buy something cheap my roller squeaks when I roll it on my face not happy but this is the very first day that I tried it and I will post results
