What is microneedling?

Microneedling, also known as collagen induction therapy, is a popular skincare treatment that involves using a device with tiny needles to create micro-injuries in the skin. These micro-injuries stimulate the body’s natural healing process, leading to increased collagen and elastin production, which helps to improve the overall appearance of the skin.

The process of microneedling begins with a numbing cream being applied to the skin to minimize any discomfort during the treatment. The device used in microneedling is then passed over the skin, creating tiny punctures in the outer layer of the skin. These micro-injuries trigger the body’s natural healing response, leading to the production of new collagen and elastin fibers.

Microneedling can be used to address a variety of skin concerns, including fine lines and wrinkles, acne scars, hyperpigmentation, and uneven skin texture. The treatment is suitable for all skin types and can be performed on the face, neck, and other areas of the body.

After a microneedling treatment, it is common for the skin to be red and slightly swollen for a few days. However, this should subside quickly, and most people are able to resume their normal activities within a day or two. Results from microneedling treatments are typically seen within a few weeks, with continued improvement over time as the skin continues to produce new collagen and elastin.

Overall, microneedling is a safe and effective treatment for improving the appearance of the skin and addressing common skincare concerns.

Safety notes and related reading

This article is informational and is not medical advice. Microneedling can irritate skin and may increase the risk of infection, pigmentation changes, or delayed healing when used too aggressively or on unsuitable skin. Do not microneedle active acne, infected skin, rashes, sunburn, open wounds, or areas that have not recovered from a previous treatment.

If your goal involves acne scars, hair loss, melasma, hyperpigmentation, stretch marks, or any medical skin concern, ask a licensed professional before using an at-home device. Use sterile compatible cartridges, avoid reusing cartridges, keep pressure conservative, and pause if skin becomes hot, swollen, painful, or increasingly red.
