As soon as I pumped this REN Bio Retinoid Youth Serum into my clean hands to apply on my skin, I knew the light texture was going to absorb nicely into my skin. I use this right after I cleanse my skin both AM and PM and moisturize after. It goes on gently and does not feel greasy. It is very gentle on my skin. I use it on my neck as well. The Bidens pilosa in this product helps visibly reduce fine lines and wrinkles. I previously used an anti-aging serum and switched it out with this. Within days, my skin felt healthier and smoother than before. I can feel the improvement of my skin barrier and visibly brighter and even skin tone. I am enthusiastic about continuing to use this to see ongoing results. I will continue to purchase this product and highly recommend you give it a try!
