How did the texture and absorption feel on oily skin?

I tend not to reach for products that feel heavy or sticky because they can feel stifling. This serum spread relatively lightly, and when I patted it in, it felt as though it absorbed into my skin quickly.
It did not leave intense stickiness after application, so it provided moisture without much of a heavy-film feeling on my skin. It suited me because I prefer serums that feel fresh and absorb quickly.

Was it easy to use before morning makeup?

After washing my face in the morning, I applied an appropriate amount over my whole face during my basic skincare step. Once it had absorbed fully, I applied sunscreen and makeup. Heavy, sticky serums can feel burdensome before makeup, but this one absorbed lightly, so it was easy to include in my morning routine.

How did I use it in my evening routine?
In the evening, I spread it over my whole face and let it absorb as I finished my skincare after cleansing. I do not like layering many products, but I could use this simply by adding one serum to my existing routine.

How did the ingredients and glow look?

This product contains liposomal glutathione and niacinamide. I prefer a hydrated, subtly luminous look over an oily shine, and I liked how it seemed to add a natural liveliness to my skin after use.

I think consistent use matters more with skincare than dramatic changes after a day or two. That is why its light feel, which made it easy to use both morning and night, felt like this product’s biggest advantage.
Who might it suit?

It may suit people who like a moisturizing serum but want to avoid stickiness, or those with oily skin who find heavy ampoules burdensome. If your skin looks dull and you want a glutathione serum for daily skin-tone and glow care that you can also use before makeup, this texture may be worth considering.
