    Absolutely adore, works like magic!

    I am new to my skincare journey in the last few months, this product works immediately to reduce redness inflammation as well as correcting skin texture and balancing of the skin barrier, I use this product in the morning and at night, I am extremely impressed with the quality and results. Coming from a sensitive skin girly that has tried many products. This is a must!

    Love that it comes as a duo

    I use this niacinamide every day and love it! I only wish we could buy it in 100 mL like the hyaluronic acid.
