## In short

I used HEEDA Glutathione All-in-One Serum morning and night for several days in Korea. Its thin, lightweight texture absorbed quickly and sat well under makeup, but the short test was not enough to judge changes in dark spots or skin tone.

## What are the texture and absorption like for HEEDA Glutathione All-in-One Serum?

On days when my skin looked rough and dull, I used it as a daily serum for several days. It had a thin, lightweight texture when I dispensed it with the dropper, and one or two drops spread moistly over the back of my hand and absorbed quickly.

Rather than leaving a heavy finish, it felt fresh, and the sticky, tacky feeling after application was not severe. It suited the feel I look for in a serum.

## Was it okay to use before morning makeup?

Because it absorbed quickly, I could use it comfortably in the morning too. When I applied it before makeup, I did not notice my makeup pilling or sitting on top of the skin.

## Were there any skin changes after several days?

Right after applying it, my skin felt moisturized and more settled, so it looked less rough. On dry days, my skin also seemed a little more lively, and after waking up, my skin tone sometimes seemed brighter.

However, since I had not used it for long, it was difficult to judge changes that take time, such as improvements in skin tone or dark spots. I think I would need to keep using it and see.

## Did it cause irritation on sensitive skin?

My skin is somewhat sensitive, but it felt comfortable during use, without stinging or irritation. According to the original product information, a skin-irritation test involving 32 people with sensitive skin reported an average skin-response score of 0.00 and a non-irritating result. Skin reactions can vary by type, though, so it is better to test a small amount first.

## My overall verdict after a short test

What I liked most was that it applied lightly, absorbed quickly, and was not very sticky. It may suit people who find moisturizing but heavy serums burdensome, or who want a fresh texture for morning and night. However, I would not draw conclusions about its skin-tone care effect from such a short period of use.
