Microneedle rollers do not work for long beards, which can be considered for beard growing surgery. Microneedle roller is a medical aesthetic technology that can help lighten dark circles under the eyes, improve dull skin, firm up sagging skin, get rid of fine wrinkles, treat scarring, and lighten discoloration. Microneedle roller, a cosmetic technique, is not helpful in promoting hair growth. Not growing a beard may be related to genetic or endocrine factors. If you are self-conscious about thinning hair and need to improve it, you can opt for hair transplantation surgery, which increases the amount of hair follicles around the lips by transplanting healthy and normal hair follicles to the target area to make the beard look thicker. It is recommended that patients who wish to undergo this type of treatment should go to the dermatology department of a regular hospital and follow the prescribed standardized treatment.
