Review: The results speak for themselves... - About 8 months ago I had this spot slowly appear on my cheek. It appears to be a sun spot/melasma. I first tried using a retinol product on it that was meant to remove dark spots but it did nothing despite using it for a few months. It also seemed to make it worse somehow. As the spot got darker, I was quite embarrassed at just how weird and old it made me look. That's when I decided to try this product and the results were amazing. I only applied a tiny dot over the spot and massaged it in every morning and at night after washing my skin. I used no other products during this time. After 2 weeks, the spot was about 50% gone. Now after 6 weeks it's about 75% gone. I tried my best to capture the results in pictures but it's a bit difficult due to how light reflects off of skin. Each photo was taken after I cleaned my skin with no product on it. I am so please with the results. The spot is hardly noticeable now and I have my confidence back. I paid nearly full price, $40 USD, for this product and it was absolutely worth it. I would highly recommend trying it if you think it might help you. Some reviews have mentioned burning or other skin irritations. I never experienced any skin irritation. If you do, I would stop using the product as that's not normal. I would also recommend using very small amounts of the product. Do not use large quantities and lather it over your skin. A small amount spreads easily and does a lot. Make sure to consistently use the product when first starting out and then you can decrease how often you use it. For example, once I hit the 5 week mark, I went from using it twice a day to once a day.
Review: Over 40 skincare trial.... - I am a huge fan of eucerin products. I am over 40 so getting serious about my skin especially on my face. I have a large dark spot on my cheek and I hate it! Feel very self conscious about it so looking for creams to dim it down in color. This one has done the most compared to others. Scent is so nice and texture of serum is silky. Absorbs fast and not greasy. So didn't completely make spot go away but helped dim so I could almost make go away with makeup. Is higher priced but good quality and lasts a while. Worth it to try.

### ⭐⭐⭐⭐⭐ I started seeing results after one and a half week!
*by A***R on January 15, 2026*

A week and a half after starting this product, together with the night cream, I started noticing a brighter and more even tone on my skin. And my sun spots started to fade. It worked for me... and really fast! Plus, it really doesn't sting a bit, and I have a very sensitive/rosacea prone skin. I combine this serum and the night cream with my Vanicream skincare regime. I later added a niacinamide serum (I got that tip from Dr. Dray on Youtube) to boost its efficiency. Be careful with the niacinamide though... some people cannot tolerate it. I think I could tolerate it because I already had my skin repaired with my Vanicream skincare regime. In conclusion, this product is worth every penny!
