How safe is the Glov at home microneedling system?

In general, in persons without any particular active skin issues, home microneedling with 0.5mm needles is generally safe. However, this kind of gentle microneedling would typically be of little to no value for treating most wrinkles, folds and scars.
I have been performing in-office, manual microneedling for over 23 years. (Note: I have said manual microneedling; there is no need for the added expense and risks of RF microneedling). Performed using local anesthetic, employing 1.5-2-0mm needles (depending upon the problem(s) being treated), and accompanied by the application of appropriate to problems Rx strength medications, this kind of microneedling when performed to the depth of creating numerous small punctate sites of bleeding, can be used to enhance the penetration of the medications and can likewise stimulate new collagen and elastic fiber production to really treat various kinds of aesthetic skin problems. Home use microneedling, on the other hand, is more busy work than true therapy. You would be wise to consult with a board certified cosmetic dermatologist who can help to determine whether your problem(s) are even best treated by appropriate professional mcroneedling or require other treatments instead of in addition. Hope this helps and best of luck.

It’s completely understandable to be cautious—microneedling, even at home, sounds intense when you hear about “needles” penetrating your skin. The needles in devices like the GloV are extremely tiny, usually around 0.25–0.5 mm. At this length, they mainly affect the very top layer of the skin (the stratum corneum and a bit of the epidermis) without reaching the deeper layers where major blood vessels or nerves are.

For most healthy skin, using a device of this size is generally low-risk, especially if you follow the instructions carefully. The purpose is to create tiny, controlled micro-channels that help with product absorption and stimulate mild collagen production—not to cause injury.

That said, there are a few things to keep in mind:

Hygiene is critical: Even tiny needles can introduce bacteria if the device or your skin isn’t clean. Always sanitize the tool and wash your hands before use.

Avoid active acne or open wounds: Microneedling over inflamed or broken skin can worsen irritation and increase infection risk.

Be gentle: Pressing too hard or using it too frequently can cause irritation or prolonged redness.

Pre-existing skin conditions: If you have eczema, rosacea, or very sensitive skin, you may be more prone to irritation.

At 0.5 mm, you’re not doing deep dermal needling—so it’s unlikely to cause serious damage—but you can trigger temporary redness, mild flaking, or sensitivity.

It’s all about careful, clean, and measured use. If you want, I can outline a safe at-home microneedling routine that minimizes risks while maximizing benefits.
