Micro-needling is the latest skincare treatment everyone is talking about, here’s everything you need to know. Micro-needling is a treatment designed to promote skin rejuvenation. Tiny needles are used to create small punctures in the top layer of skin. This causes the body to create new collagen and elastin. We are basically tricking your skin into thinking it has been wounded, but as a result, we're thickening the skin and improving the texture with this procedure, Debra Jaliman, Dermatologist. The treatment can also help heal acne scars and reduce pore size. A micro-needling treatment begins with cleansing the face, then a numbing cream is applied. Next, your dermatologist will apply a serum that promotes skin repair and healing. The micro-needling pen is then passed back and forth over the entire face. When the treatment is finished more serum is applied and finally, a mask is applied to seal everything in. Micro-needling doesn’t hurt as the numbing cream takes away what minimal pain the needles cause. Those with cystic acne, eczema, rosacea, and very sensitive skin should not get this treatment. At-home micro-needling tools are available but experts recommend getting it done professionally for the best results.
