Glutathione serum for daily tone care: HEEDA Glow Serum

In short

I tested HEEDA Glutathione Brightening Tone Care Glow Serum morning and night for several days in Korea. It felt light on my skin and left it feeling comfortably moisturized with moisturizer, though results may vary by skin type and condition.

Could I use it in the morning too?

I chose this serum as a tone-care product for skin that had tanned over the summer. Rather than a heavy, stuffy cream, I was looking for a texture that would be easy to use every day, and I especially wanted to see whether it would feel comfortable before makeup.

After using it for several days, I found that I could use it comfortably both morning and night. In the morning, I applied the serum after cleansing, then finished with lotion and sunscreen. I did not skip sunscreen even when using the serum during the day.

What were the texture and pre-makeup feel like?

It felt moisturizing when I dispensed it onto the back of my hand, but spread over my face it adhered more lightly than I expected. After spreading a thin layer over my whole face and pressing it in with my palms, it did not feel especially sticky or stuffy.

Rather than applying a large amount at once, what worked better for me was spreading a moderate amount from the inside outward, then layering the remaining amount lightly once more. Even when I used it in the morning, it did not feel particularly heavy before makeup.

How did I use it in my evening routine?

At night, I used it after cleansing in the order of toner, glutathione serum, and moisturizing cream. Seeing that it was a tone-care serum containing glutathione and niacinamide, I used it with the mindset of keeping it in my usual routine and observing my skin’s condition, rather than looking for a change after one or two uses.

How did my skin look after several days?

What I liked most was the feeling of skin looking smoothly moisturized rather than excessively shiny. When I followed the serum with moisturizer, my skin’s surface felt softly smoothed, and the next morning it felt less excessively dry.

I found a comfortably moisturized state more comfortable than days when my makeup lifted because of dryness, and it was fine to use as part of my morning skincare steps. However, skin changes and the feel of use can vary depending on skin type and its condition at the time.

Final thoughts: how was it as a daily tone-care serum?

I felt it was worth using when I wanted a serum with a light, moisturizing feel. In the morning, I applied a thin layer after toner and used sunscreen; in the evening, I gave it a little more time to absorb. I plan to keep it in my morning and evening routine and continue watching my skin tone and condition.
