How did it feel on oily, dehydrated skin?

My T-zone tends to get shiny, while my skin also feels dehydrated underneath, so I often notice tightness and dullness as the seasons change. Since I do not prefer sticky or rich serums, I tested this one mainly for how it spread and whether it felt sticky.

Is the texture sticky?

It had a watery texture with a yellow tint. On my skin, it felt hydrating rather than running excessively, and it seemed to absorb clearly, so I found it minimally sticky.


The dropper format, which lets me dispense just the amount I need, was convenient too. It also felt light under makeup without pilling.

How did I use it?

After cleansing, I smoothed my skin with toner, then dispensed two to three drops with the dropper and spread them over my face. I applied it with a light massaging motion, then cupped and pressed my face with my palms to help it absorb.

How did my skin feel after one week?

For me, before use, oiliness, dryness, redness, and areas of pigmentation made my skin look dull. After one week, my overall tone seemed about a shade brighter, and I felt that my dry, rough-looking skin had a subtle glow.

The area around my mouth also seemed brighter than before, so I started wearing a thinner layer of base makeup. Cream and makeup tended to sit well after the serum, so I used it often in my daily routine.

What ingredients were mentioned?


The original post introduced glutathione and niacinamide as key ingredients. However, the assessment of skin changes is based on my observations from one week of use.

Overall: Who might it suit?

It may be worth considering if you are concerned about dullness and small blemishes and want a non-sticky serum. For me, the most satisfying points were its watery texture and light feel before makeup.
