While many people think of acne as a problem faced by teenagers, it can follow you into adulthood.Whenever you deal with acne, it can be a frustrating and embarrassing, especially if you can’t find anything that works to treat it.Once you get rid of your acne, though, acne scars can still plague you. However, all hope is not lost. You're not stuck with them!Using a derma roller for acne scars can help reduce your acne problems drastically.If you're not familiar with derma rollers, they're tiny devices covered in needles that you roll over your skin to make tiny holes. That means your body goes a bit mad to repair them, helping to repair your blemishes and scars too.Choosing any new product can be difficult, though. However, we're here to help you so finding the best derma roller for acne scars isn’t a challenge.We'll look over not only the best product, but what makes it the best product so you know exactly what you’re buying. Criteria First, let’s look at the best derma roller size for acne scars.This is an especially important number to know because there are certain needles you shouldn't use on your face. For acne scars, a 0.5 mm to a 1.0 mm length needle is a good idea.Anything lower than this won't produce results and anything higher than this will cause damage and is dangerous to use on your face.However, if a derma roller is for more than just acne scars, that's ideal. It's multiple products in one! FDA approval is also an important feature, as it'll give you peace of mind. It's important to note, however, that you can't use this treatment on open acne or raised scars, rather than scars depressed into the skin. To properly treat these areas, a derma roller shouldn’t have too many needles or needles that are too thick.These can slice your skin rather than working as micro-needling should.
