Brightening serum for dehydrated oily skin: HEEDA Glutathione

In short

I used HEEDA Glutathione High-End Glow Brightening Serum for about two weeks on dehydrated oily skin in a heated office. Its thin texture absorbed quickly and felt comfortable before makeup; I felt less inner tightness and a more even-looking tone, though these results reflect my own skin and use period.

How did it feel on dehydrated oily skin?

My skin is dehydrated oily skin: smooth on the surface but tight underneath. When I spend a long time in a heated office, it tends to feel sensitive and tight, so I used this while paying attention to both dryness and a dull-looking tone.

Was the texture and dropper easy to use?

It has a thin, flowing water-glow texture that felt as though it adhered quickly when applied. It finished without stickiness, so it did not feel heavy even on days when I went through several skincare steps or used it before makeup.

The dropper made it easy to control the amount one drop at a time. At 30ml, it was not too burdensome to keep on a bathroom shelf or carry in a bag.

What changes did I notice after about two weeks?

After using it consistently for about two weeks, the skin tone that had looked dull seemed a little more even when I looked in the mirror, and I barely felt morning tightness underneath my skin. My makeup also seemed to apply more thinly and evenly than before.

The day after applying it at night, my skin texture seemed smooth and looked more radiant. I did not feel much of the dryness I had worried about when using a brightening product.

Does it pill with other skincare products?

Even when layering toner, ampoule, and serum in that order, I did not experience pilling. It also tended to absorb without conflict when used with a moisturizing cream, so it worked well in my daily routine during the dry season.

Who might it suit?

It may be worth considering if you want a brightening serum without a heavy feel, or if you are concerned about both inner tightness and dull-looking skin. However, the changes in tone and skin texture are observations based on my skin condition and about two weeks of use.
