Microneedling is a procedure where a series of small pricks are made on the skin using a hand-held pen-like device and works by stimulating growth of new collagen. Various nutritional serums can then be applied to allow better skin healing. It is mostly used to treat scars, large pores or wrinkles on the face There would be some redness for a few days after the procedure but makeup can be applied. Your skin will also be more sensitive to the sun as it heals, so you should avoid the sum or use sunscreen. Results are usually seen after a series of procedures, determined by your skin condition.
