My skin had become sensitive, with blemish marks that lingered and an uneven-looking tone, so I tried the HEEDA serum for two weeks.

## How did it feel on sensitive skin?

The product I used felt closer to a fresh, watery formula than a thick oil. It absorbed lightly without feeling sticky on my skin, and even when I reapplied it, it did not pill much.

The scent was not strong, and I did not feel any irritation when applying it. It was comfortable to use even on sensitive days or over areas with blemish marks because it did not sting.

## How did my skin tone and blemish marks look after two weeks?

The product description states that it contains 99% high-purity glutathione and niacinamide. In my case, from the second week of use, I felt that my blemish marks looked lighter in the mirror than before, and my skin tone also looked a little more even.

On days when redness stood out, I also felt that my skin seemed calmer after applying the serum. However, these were personal changes I noticed in my own skin over the two weeks.

## Was it suitable before makeup?

Right after application, it felt as though a thin layer of moisture remained, and after some time, my skin seemed to develop a natural glow. It did not cause my makeup to lift when I used it after morning cleansing, and my foundation tended to apply relatively thinly.

Compared with times when my base makeup would lift in the afternoon because of dryness, it seemed to last longer during the testing period.
