How does the HEEDA brightening serum feel on dry-yet-oily winter skin?

My skin is combination and dehydration-prone, so it reacts to the seasons — in winter I feel dry pretty quickly after washing my face. Too much oiliness can also bring on breakouts for me, so I paid close attention to the balance between hydration and oiliness while using this.
What is the texture and absorption of the HEEDA glow serum like?

The serum was watery enough to run down if you applied too much. For me it felt mostly hydrating with a very light hint of oiliness mixed in, and that oiliness never felt off-putting on my skin. Rubbing it in lightly, it absorbed well and didn't leave much of a surface film.


How many layers of the HEEDA serum at night?

During night care I layered it 2-3 times. It's not a rich serum, but it's not overly light either, and even after multiple layers I felt it finished without any stickiness. I let the serum absorb, then finished with a cream.

Does the HEEDA serum balance dryness and oiliness?
On days I skipped my morning cleanse, my skin got pretty oily, but right after a thorough cleanse, if I put nothing on, it felt dry fairly quickly. This serum was on the side of reducing that inner dryness for my skin, and the light oiliness never felt like too much. As for changes in blemishes or pigmentation, I think that's something I'd need to judge with more consistent, longer-term use.

What does HEEDA claim the serum does?

The product lists a glutathione and niacinamide combination, liposome technology, and a low-irritation vegan formula as its key features. That said, skin results can vary by person, so I focused on checking hydration and finish on my own skin.
