Dermapen-branded devices are sold exclusively to medical and skin-care professionals, but knock-offs and electric microneedling products manufactured by other companies are surprisingly easy to purchase online. Should you ever use one? In short, no.Â
âMotorized microneedling pens for home-use introduce the significant potential for many complications, such as scarring, infection, and contact dermatitis,â says Dr. Chesnut.
Besides the potential for skin damage from user error, hygiene concerns should hold you back. While doctors use a brand new, sterile needle cartridge for each Dermapen treatment, home devices tend to come with only one or two sets of needle tips that youâre responsible for adequately sanitizingâunless you continually shell out for replacements.Â
Without proper sterilization, reused needles can spread bacteria across the skin and even introduce it below the surface. This can worsen acne and cause infection and inflammation.
If youâre still keen on microneedling at home, a derma roller is a safer bet. These home devices typically have shorter needles than those youâd find in a doctorâs office, so they create only superficial woundsâimpacting just the outer layer of the skin.Â
According to the FDAâs regulatory considerations, this is an important safety distinction. In the agencyâs draft guidance for microneedling devices, the tools are classified for regulation according to the depth of penetration.
Derma rollers that affect just the outermost layer and intend to give skin a smoother, more luminous look fall outside FDA regulations, but any designed to impact the epidermis or dermis for the following uses are subject to FDA enforcement action.
- Treating scars (e.g., acne scars, atrophic scars, hypertrophic scars, burn scars)
- Treating wrinkles and deep facial lines
- Treating cellulite and stretch marks
- Treating dermatoses
- Treating acne
- Treating alopecia (hair loss)
- Stimulating collagen production
- Stimulating angiogenesis (blood vessel growth)
- Promoting wound healing
To achieve results along those lines, youâll want to be treated with an in-office device.
