iS Clinical C Oogserum Advance+

The texture is surprisingly light—no greasy residue under makeup—and my under-eye area looks noticeably calmer by mid-morning. I’ve been consistent for about two weeks and the fine lines seem a bit softer, plus the vitamin C gives my skin a subtle brightened feel.

After about three weeks of using this morning and night, the puffiness under my eyes has noticeably calmed down. The lightweight serum absorbs fast without any sticky residue, which is a huge plus for layering with my moisturizer.

The dropper makes it easy to get just the right amount for both eyes without wasting any. I’ve noticed the dark circles under my eyes look a lot less noticeable after about three weeks of consistent use.
