This is the first derma roller I've used and I honestly could not recommend everyone has one in their bag. Its great!
I don't have many acne scars or suffer badly from acne but i have large pores and often oily pores. I've used this since I've purchased it and I definitely have noticed it helping the products sink in more and therefore allowing the products to do their thing 50% better than without it. I use it every 2nd night after the shower, as the steam opens up the pores. I usually use a mixture of serums and moisturisers in conjunction to this product. So please keep that in mind.
The only downside of this product is that its recommended that you should change the head after 15 uses, but ADORE doesn't stock the heads nor could I find it anywhere else. The body of the product is basically hollow plastic as well and the quality besides the needle head is subpar. Once cleaned, the head gets stiff when rolling and you need to use force to push it forward (which you aren't meant/need to do) - I would recommend purchasing the other derma roller on here as its much better quality and is cheaper!
The product itself I would recommend, but not the brand.
