Always Mary & May products amaze me, this is my second purchase

Me encanta porque me ahorre dinero en un excelente producto

My mom loved it and it didn't cause any reaction on her sensitive skin

The Mary and May Niacinamide Serum Twin Pack contains two high-concentration niacinamide serums to visibly refine pores, even out skin tone, and control excess oil production. The lightweight, fast-absorbing formulas provide a potent dose of this multi-tasking ingredient to improve the appearance of blemishes and reveal a smoother, more refined complexion.

It is not that bad but it is not for me

Good for all skin and use everyday

the amazing feeling after using this product.

super gentle at only 2%, much better than other harsher 10% brands which tend to be irritating and damaging. It is a bit sticky though but leaves me skin super shiny

Double Mary and may serum is double benefits I Take one and give the other to my mom

My friend who has a dry skin likes it very much. It's a bit thick for oily and combo skin

Wonderful serum for acne-prone sensitive skin. It works really nice for soothing the skin and keeping it moisturized and hydrated.

Makes a nice little gift for any skin type.

good buy, good product. gentle on the skin and good overall. Will repurchase

This duo pack was so affordable and got it so I could keep a serum and get the other to a friend, plus a came with a mini eye cream. The serum is nice and absorbs in quickly and has brightened my skin after using it.

High recommend all products at here

Doesn't sting my skin. Eye cream is heavily fragranced but is thick and soothing.

I just bought 2 of this serum, love it so much
