Daylight Oasis Vitamin C Serum

Have been using this product since it was launched. It does help to lighten my dark spot and aging spots, balance the uneven tone and my skin looks brighter. After one or two upgrades, the current version has improved a lot with great texture and no spillage. Thumbsup.

I was not a fan of the old formula but decided to give it another go when it was relaunched. I am glad I did as my skin always looks noticeably brighter upon application and have gotten compliments because of it. I am now into my second bottle and it will continue to be a part of my skin care routine.

Effective on blemishes

Been using this product since 2023. Was looking for something that could help treat my blemish due to acne. Tried multiple products, and none were as effective as this. I like the current formula, where the serum's consistency is less watery (aka less wastage) and it does not have as obvious skin peeling effect compared to the previous version.

Fights inflammation and blemishes

Diligently applied it everyday ever since receiving it and the results are great! Achieved clear skin and it also helped to fight acne as well. Though it may sting a little upon application but skin adjusted fast to it soon after. My skin absorbs it very well too! If you have sensitive and acne-prone skin, don't worry and give this a try. No regrets at all!
