they say this is supposed to act as though you just put on a face mask! consistency is SO smooth- almost like a primer consistency??

Moisturizing and light

I've been meaning to get this and when I finally bought it, the product certainly didn't disappoint. Already, I love that this is a full bottle. Whenever I feel lazy and not doing much skincare, this makes my skin feel soft and moisturized. I think this will last a long time.

Love Numbuzin!!

I use this at night after toner/essence on my face and neck and wake up with such smooth and clean skin. Highly recommended it!


I have super sensitive skin and doesn’t break me out. I have bought two already!

Different skin types will react differently

I personally LOVE all these skin care products and I’m heavy on this serum as well as the face creams before my makeup steps! I love the natural glow they give me and I’ve noticed my skin feels and looks more alive and fresh:) I got an ad on YouTube about this skin brand and was skeptical at first but I bought a couple products and boom my addiction began😅🤣 In all honesty I do love these products and believe they are worth the money ! However I will say that everyone’s skin type is different and these may not work on you so don’t stress it ! Just try it and see how it works on you !!!! 10/10 recommend
