I use https://www.mon-lumiere.com/products/anti-aging-infusion-solution at home microneedling device not only for my face, but also for my neck and décolleté. These areas usually show their age the fastest, but the serum did a great job with wrinkles. Microperforation allows PDRN to work in the deep layers of the dermis, restoring elasticity. In just three weeks, the skin on my neck became much tighter and smoother. I am very pleased that I received professional care without going to clinics.
