Microneedling does not treat acne. If done, it can cause acne to flare up more severely and increase the risk of skin infection.
Dr. Tran Nguyen Anh Thu, a specialist in Dermatology - Cosmetic Dermatology, Tam Anh General Hospital, Ho Chi Minh City, said that micro-needling is a minimally invasive procedure on the skin. The doctor uses a roller with small needles, actively creating tiny holes on the skin surface. These injuries activate the body's natural wound healing response. The body will release growth stimulants, create new blood vessels and many proteins (collagen, elastin). These proteins help the skin to be plump, firm and smooth.
Microneedling is commonly applied on the face but can also be applied on the legs, back, neck, head or areas of aging, damaged skin. This method is indicated for the treatment of pitted scars, shallow scars, especially acne scars; large pores; fine wrinkles; skin rejuvenation; patchy hair loss.
However, microneedling is not used to treat acne that is inflamed. According to Dr. Thu, many people mistakenly believe that microneedling can treat acne due to misunderstandings or inaccurate information from beauty salons or social networks.
Acne contains bacteria, especially pustules, nodules and cysts. When rolling the needle, the needle will come into contact with acne-causing bacteria, spreading the bacteria to healthy skin areas, irritating and causing acne to flare up more and more severely. The procedure creates small wounds that can cause inflammation, infection and acne to flare up more severely.

In addition, other cases that should not be microneedled include skin that often has rashes (contact dermatitis); is suffering from atopic dermatitis (eczema), psoriasis, herpes; patients with blood clotting disorders or are taking anticoagulants; cancer patients undergoing chemotherapy or radiotherapy. The treatment area has moles or tumors that change in size, shape, color, or bleed. Patients should not be microneedled. Patients should go to a hospital specializing in dermatology or oncology for examination.
Dr. Thu noted that skin treatment with microneedling does not have immediate beautifying effects but requires recovery time. The skin needs several days to several weeks (depending on the depth of the needle in the skin) to see results. Patients need to carefully select the information introduced, verify before applying and should go to a specialized dermatology hospital for appropriate diagnosis and treatment.
