My skin is glowing and I’ve noticed my uneven skin tone already fading! Such a great product.

Wish I Would Have Found This Years Ago!!

After struggling with adult acne throughout my 20s, I have residual scarring. Thankfully, I have hardly anymore breakouts due to Osea's products (and changing a few things internally) after only 6 months of use. This is THE BEST serum I've used for actually reducing pigmentation. I noticed after 2-3 days! After a whole bottle, my skin is so much brighter and it now glows! I hardly wear makeup anymore. The bottle is small, but a little goes a long way. Osea, I would totally buy a bigger bottle if you made one!!! Thank you for all you do!

Love it!

The serum has absolutely brightened my skin, and I noticed with the first few uses. It's not sticky, and it lasts a long time! I really like it, especially after trying not at least 5 others before! Definitely my favorite :)

Soft skin

I like this brightening serum better than the vitamin sea serum I have been using. It does not smell fishy like the vitamin sea serum and it absorbed quickly into my skin. I will probably switch over to the brightening serum permanently for those reasons. I feel that the brightening serum absorbs well and will not make my foundation feel oily.

Worked for my pigmentation

I have stubborn freckles and solar lentigo since I was 15. It’s in my genes and despite not staying under the sun, a lot more freckles developed. I tried laser which gave me post inflammatory hyperpigmentation and tried for another 4 years, spending a few thousand bucks on facials which did nothing for me. I decided to give this a go and it did not work for me initially as i used it only once per day. However, when i started using it twice a day, by the end of 2 months, my pigmentation lightened by 70% and i can’t see them clearly unless i stare very hard at my face. This product did for me what many lasers and facial sessions could not do. I cannot thank OSEA Malibu enough. As an Asian, i was always bothered and felt insecure due to my freckles as skin tone is quite fair which makes the freckles stand out even more. I can finally put on some blusher and not be worried that it will highlight my freckles instead. Thank you for this great product!

Exceeded expectations

This is 100% the best serum I’ve used. It evened out my skin tone and lightened dark spots and sun damage. It’s hydrating and smoothing. I’ll never use anything else! Super happy with my purchase
