Glutathione glow serum for dull skin, 2-week test: HEEDA

In short

I used HEEDA Glutathione Brightening Glow Serum morning and night for two weeks after toner. The fast-absorbing ampoule texture and layered hydration felt comfortable, but I did not see a clear change in dark spots.

How did I use it for two weeks?

My skin tone looked dull and felt dry, so I tried HEEDA Glutathione Brightening Glow Serum. I applied it morning and night for two weeks after toner.

What were the texture and absorption like?

It had an ampoule texture that was neither too runny nor too thick. When I dispensed it onto the back of my hand and worked it in, it spread smoothly and absorbed relatively quickly without sitting on the skin. It left a subtle hydrated feeling afterward.

How did my skin look after two weeks?

Right after applying it, my skin seemed to have a glow. When I used it before base makeup, my skin looked more hydrated. After about a week, I felt that my overall skin tone looked a little more even and clear.

However, I did not notice a change where dark spots visibly disappeared. When I layered it twice, the hydration seemed to last longer, so I used it on days when dryness was bothering me.

  • I applied one extra thin layer over my cheekbones, where dark spots concerned me.
  • The day before an important appointment, I applied a generous amount of serum and used it with a modeling pack.

It may be worth considering if you prefer a less-sticky serum texture or want hydrated-looking skin before makeup. For me, the hydration and glow were the most impressive parts over the two-week test.
