Yes, the Skin Roller gives the same effect and results regardless of gender, pigment or age. Our treatments are only to be used on persons over 18 years of age.
The needles contain 8,23% nickel and 0,23% titanium. If the needle would contain less than this, the needle wouldn’t be durable enough. If you disinfect the roller before and after every use, the needle shouldn’t cause any allergy. If you are very sensitive to nickel, you might get a reaction. The needles are covered with silver, so the skin won't be in direct contact with the nickel.
Regardless of this, we advise you to withhold from use if you are unsure.
