Seems to be working!
(This review was collected as part of a promotion.) I have been using this serum once daily at night for about a month now. I have seen some slight improvement on a few small sun spots I have, I will continue to use it until the bottle is done to see if the spots fade even more and then will evaluate if I purchase it again. I have very dry sensitive skin and I have not seen any irritation with this serum and it leaves my skin moisturized. It layers well with the rest of my skincare, absorbs quickly without leaving a sticky feeling and has a very mild scent. I will probably purchase this once I run out if I see more improvement with my sun spots.

I’m excited to keep using this serum.
(This review was collected as part of a promotion.) I have been using COSRX The Alpha-Arbitin 2 Dark Spot Care Serum for about two weeks now, 4 to 5 times a week, and I am really liking it so far. I can already tell a few spots on my face are starting to look a little lighter, which makes me excited to keep using it. One of my favourite things about it is that there is no scent and it doesn’t feel greasy at all. The texture is lightweight, absorbs quickly and makes my skin feel good. It also layers well with the rest of my skin care and hasn’t irritated my skin or caused breakouts. So far it feels like a gentle but effective serum. I received this free from Influenster for my honest opinion.

Works well for acne spots
(This review was collected as part of a promotion.) I really enjoyed testing this product ad I have some sun spots on my skin and I get dark spots from acne. The flat cap of the bottle makes it really easy to open and hold while using the dropper to dispense directly onto the skin. It's a very fast absorbing product and it also didn't affect my make up on days that I wore foundation. It also sat really nicely under my daily sunscreen never leaving any residue behind! After using this serum for a few weeks I noticed that the dark spots from post acne cleared up quite nicely and it made my skin look more radiant. I am going to continue to use this serum and see if it makes any difference in my sun spots!

Post acne savour
(This review was collected as part of a promotion.) I have dark spots on my face and discolouration and this product really helps with those post acne marks. It speeds up the recovery time of those spots which is awesome. I like the dropper because it gets the product where it needs to go. This does not irritate my skin at all but I did stagger the product however I did not feel any discomfort when applying or after. The bottle is a very good size and will last awhile. It’s very simple packaging just black and white so the product really has to sell itself. This product won’t help with the sunspot that has been on your face for awhile but it will help with those new marks.

Effective product
(This review was collected as part of a promotion.) A well-formulated serum that targets dark spots from multiple angles. The blend of alpha-arbutin, tranexamic acid, and niacinamide is effective for gradually brightening and evening out skin tone without irritation. It absorbs easily, layers well, and fits into most routines.
That said, this isn’t a quick fix—results take consistency, and sunscreen is a must or you’ll undo the progress. Best suited for mild to moderate pigmentation or post-acne marks. If you’re patient, it delivers steady, noticeable improvement, just don’t expect dramatic overnight changes.

Do I need more time?
(This review was collected as part of a promotion.) I enjoyed that this product brought the hope of reduced dark spots. Unfortunately, I can't see any visible difference in my spots. The eye make up picture is the before and the (sans makeup) second photo is after one month of usage. The product goes on smooth, evenly, and doesn't have any real smell to it which I like, but if it's supposed to reduce the dark spots, maybe I need more time? I'll keep using this and report back after a few more months. The product goes along way using the eye dropper so I will likely still have product for those months.

Effective and light-feeling
(This review was collected as part of a promotion.) I’ve been using this product for about 3 weeks now. My first impressions were that it felt very light and absorbed quickly, and that it did not feel heavy or greasy on my skin, and it did not cause any breakouts. It doesn’t have a scent which is nice too. I have some dark spots from sun damage and texture on my cheeks which I was hoping to address, and I’ve already noticed some improvement so far. The dark spots have lightened slightly and my skin looks and feels more smooth. COSRX’s dark spot care serum has been great!

I m very honest and it works if you are consistent
(This review was collected as part of a promotion.) I have been consistent with using this serum everyday for my dark spots and honestly it’s not a magic overnight fix. It really made a difference on my face. When I first using I noticed little redness but disappeared once serum settled on my skin. Texture is super lightweight absorbs quickly and no irritation but sometimes it can pill if I layer too many products on top. After 3 weeks my skin stated looking lighter and less dull. Patchy areas on my face slowly began to even out. Just need to be routine and apply sunscreen everyday for best results
