Glutathione serum for dull-looking skin, tested 3 weeks: HEEDA
In short
HEEDA Glutathione Serum 30ml is a Korean skincare serum I used morning and night for three weeks while balancing childcare and work. It felt lightly hydrating and sat well under makeup, but the 30ml bottle may last about a month if applied generously down the neck.

How did I use it for three weeks?
While balancing childcare and work, I often had days when I was short on sleep, and I was concerned that my complexion looked dull by the afternoon. Looking for a basic routine I could keep up at home, I used this serum morning and night for three weeks.
What were the texture and application like?
When I dispensed it with the dropper, the clear serum flowed smoothly. It did not spread too easily like water or feel sticky and clumped together; after a few gentle rolling motions, it felt as though it absorbed without sitting on the surface.
After use, it left a light, moisturized finish rather than a sticky oily feeling. Its subtle, fresh scent was not overwhelming while applying it.
Does it pill before morning makeup?
In my experience, it did not pill or clump even when I used it before makeup on busy mornings. My foundation also seemed to adhere in a relatively thin layer, so it was easy to include in my pre-work routine.
What order did I apply it in?
- After cleansing with a mildly acidic foam cleanser, I smoothed my skin texture with a water toner.
- I placed one drop of serum each on both cheeks and my forehead, then spread it gently.
- After rolling it from the inside outward, I lightly pressed it in with my palms.
- I finished by layering on a moisturizing cream.
- In the morning, I applied sunscreen as the final step of my skincare routine.
What was disappointing during use?
Because it comes in a 30ml size, I felt that one bottle could be used up in about a month if you tend to apply it generously not only to both cheeks and the forehead but also down the neck. A larger-size version would be more convenient to use.
Who might it suit?
- People concerned that their makeup lifts or their complexion looks dull by the afternoon
- People who prefer a fresh finish over a heavy, sticky oily feel
- People looking for a simple home skincare routine to follow morning and night
- People looking for a serum to use before makeup
