The Numbuzin skincare line is excellent for mature skin. The toner is very refreshing and adds moisture and a healthy glow. It contains 50 probiotics and vitamins so the skin looks rejuvenated as soon as you put it on after cleansing. I cleanse my skin with Bidoderma sensibio miscellar water and Cetaphil gentle cleanser. Then I use the toner and Numbuzin 5 for hyperpgimenation. Let it absorb and add Cerave PM moisturizer. Twice a month I use Skinceutical retinol 1.0 to exfoliate my skin. That's all it takes to have a healthy looking skin. You must wear sunscreen every day to protect your skin. I use the ELta MD SPF 46. The Korean Numbuzin skincare line is fantastic for mature skin. Non irritated. Non comedogenic. Highly recommend. :-)
