numbuzin No.5 Serum | Tranexamic Acid 4%, Niacinamide 5%, Glutathione, Vitamin C | Vitamin Concentrated Serum | Hyperpigmentation| Suitable for Sensitive Skin, Korean Skincare | 1.01 fl. oz.

This is an amazing serum that was highlighted by two great dermatologistsyou can still use it with your C serum and it does not conflict or changes the efficacy of the c serumYou can also use it after retinol in the eveningsI have not been able to find another serum at this price point as good as this

Great ingredients and feels Amazing on the skin. I have sun spots and have used this for almost 4 weeks every morning, before my sunscreen and I have seen a slight fade, great thing this serum is not too oily like other Vitamin C serums (I tried Timeless 20% and HATED it, so oily) and I definitely will be repurchasing this one.

I love it. My skin is much smother and softer. It’s also decreasing the dark spots on my face.

Is my first time using the product and it goes good, but, slower than I want, I was thinking it will be better based on their reputation and just is an average product.

Me encantó un oxidante muy bueno aunque no me quito las manchas del melasma me dejaba la piel muy hidratada

Esto realmente me ayudó mucho más que otros productos que estuve utilizando, lo único malo fue que me salieron comedones pero eso lo solucionó con otro producto, por lo que realmente si me sentía mal era por las manchas tenía en la frente y del otro lado de la cara también pero solo tengo fotos de este lado

I love this item works great on the skin

I'm not sure if this serum hides dark spots, but it is supposed to. I haven't used it everyday maybe that's why, but it is affordable. There's no scent and it's not sticky.
