MASTINAMastic Serum Roller - Dark Circle Remover & Eye Serum for Brighter, Firmer Under Eyes, Korean Skin Care, 0.5 fl oz,White Mastic Complex 63% + Tranexamic Acid 2% + Niacinamide 5%

Use the small-sized roller to gently massage areas with pigmentation or dark spots. Since it’s a highly concentrated ampoule, even a small amount provides plenty of moisture, and because you don’t need to use your hands, there’s no product loss. It also offers a massaging effect, which I think is great for wrinkles too. I personally use it to press on pressure points to promote blood circulation in my skin. It has a subtle herbal scent that makes feel soothing and pleasant.

It feels like my skin has become moist and healthy. If I apply it before sleeping, my skin will become much softer the next day. It's not troublesome, It made my skin smooth and better. It's easy to use

Feels nice but no difference noted. Leaves skins Dewey.

The roller head gives me a professional esthetic vibe. No breakouts so far and hopefully it can erase my dark spots on my cheek bones.

First off, the glass bottle is heavy so I was assuming the content will be almost full. You cannot see from the outside but when I peeked in with a light shone down, I see it just at about the halfway mark. That is pretty little for the money we pay. I am not sure if I just got a dried out old stock bottle but just for the volume (vs bottle size and money paid) alone, I will not be repurchasing.Granted, it went on pretty light. Just the right amount of stickiness, then gets absorbed really quick. I feel that it created a moisture barrier that kept my facial skin hydrated while I slept. BUT, 2 days later..after 2 evening uses...I suddenly got break outs. I very rarely get breakouts. Not red angry one but clogged oil glands that is pushing out. I have not made any changes to my entire skin care other than this as I want to make sure things are consistent so I can pin down the cause if something goes awry. I always do gentle exfoliation too so it cannot be caused by me not doing so to help skin turnover along.Value-wise and short-term effect...it is a no go for me. I wish I can return a used product for the adverse effect.

The moment it’s applied, the eye area feels instantly refreshed and well-hydrated. The scent is subtle yet pleasant. I especially appreciate the convenience and hygiene of the roll-on applicator—no need to use fingers. It’s an all-in-one ampoule that simplifies my routine without compromising effectiveness. I highly recommend it.

Muy bueno, deja la piel bien humectada y luce radiante.Pero el frasco NO TIENE SELLO. La caja trae, pero sería mucho más importante que también el producto llegara sellado, de lo contrario no lo volvería a comprar.

The roller feels cool and soothing, and the serum absorbs quickly without any stickiness. I keep it in the fridge for an extra refreshing touch. It’s only been a week, but I’m hoping it will help reduce puffiness under my eyes.
