The ORA Electric Microneedle Derma Pen System takes the guesswork out of microneedling by producing controlled, precise needle strokes faster than a traditional roller. What makes this pen stand apart from the rest is the adjustable needle head (varying in length from 0.25 mm to 2 mm), and the built-in vibration mechanism that provides deeper needle penetration.The fine needles penetrate skin just enough to create small punctures that send your skin healing signals. This prompts the production of collagen and elastin to produce smoother, firmer, healthier and younger-looking skin. Use the pen on you face or body to reduce the appearance of acne scars, fine lines, wrinkles and stretch marks. You can even use it on your scalp to stimulate hair growth. The Electric Microneedle Pen from ORA provides a 100% pain-free experience with professional results, all from the comfort of your home.ORA Electric Microneedle Derma Pen System includes:Electric Microneedle Derma Pen: features 5 adjustable speed settings2 Replaceable Needle Tips: each with 12 needlesAC Adapter and Wall ChargerTip: ORA recommends using a serum or cream after the needling treatment, as this will enhance the absorption of the skincare product. Some users use the cream or serum prior to the roller treatment. However, the use of creams or serums is not necessary with the rollers—meaning you can use the rollers on their own. The roller dramatically enhances the absorption of your skin care products when you follow up the treatment with your favorite serum or cream.
