Hello MAVIS! Thank you for sharing your experience with our Mela B3 Dark Spot Serum with Melasyl and 10% Niacinamide.

Your feedback is incredibly important to us, and we appreciate your honesty.

Too early
I don’t think it’s been long enough for the product to have progressed in diminishing the dark pigmentation.

Mela B3 Dark Spot Serum
I have used the Mela B Serum for 1 month and 5 days. I have Melasma on the forehead. There has been no significant improvement yet. I will keep trying for a few more weeks before looking for a different product.

Dark spots fading
I really can see the spots fading already. My skin is smooth, and not irritated. My skin is super sensitive and this isn’t burning me at all

Really Works, Need to be Consistent with Use
I absolutely love this serum, I have rosacea and this has gotten rid of my dark red skin spots on my cheeks (which is the only part of my face affected by rosacea). My skin looks and feels a million times better, even my family and colleagues have commented on how much better my face is. FYI - I have been using it consistently morning and night for the past 6 months.

Careful with sensitive skin
Unfortunately it was so harsh on my skin and caused my eczema to go crazy. It’s crazy because I used the LRP retinol without it being too harsh. Now I’m stuck with an expensive bottle of serum I can’t use.

Dark patches on face of Black skin
As I aged I developed dark patches on my face. A few years ago, a friend who I hadn’t seen in years said I looked like I had a beard. I tried different things, even improving my diet. A month or so ago I saw these products on a morning show. I ordered the serum and it is working. I am so satisfied!

Great product
I have been using B3 dark spot serum for about 6 months. It has significantly reduced dark spots on my face. They are far less visible without makeup. I now only use tinted sunscreen daily. I occasionally use a bit of concealer but not very often.
