What did HEEDA Glutathione Glow Serum feel like to use?

My overall skin tone looked dull, and I was concerned about spots and pigmentation, so I tried this while comparing products with glutathione. The dropper made it easy to dispense only what I needed.

It had a thin, lightweight water-glow texture when dispensed onto my hand. It felt like it adhered quickly as I spread it over my face, and in my experience there was very little stickiness or product sitting on the skin.

Could I use it before makeup?

Even when I applied makeup after using it in the morning, it did not feel like it was pilling. It suited me because I prefer a fresher feel to sticky serums.


How did I use it?

- After cleansing, I used toner to smooth my skin texture.
- I lightly spread the serum over my whole face.
- On days when my skin felt dry, I layered it once more before cream.
- I used it morning and evening.

How did my skin feel afterward?

Rather than aiming for an overly bright-looking effect, I used it as part of a routine to gently care for my skin’s natural clarity and inner glow. Especially the day after applying it at night, my skin felt soft and neatly balanced. However, skin changes and how a product feels can vary from person to person.
