How did the texture feel on dehydrated oily skin?

Brightening serum for dehydrated oily skin: Heeda Glutathione Tone Care Serum

Because I have dehydrated oily skin, too much oiliness can cause breakouts, while severe inner dryness can make my complexion look dull. This product had a clear, transparent essence texture and did not run excessively when I dropped it onto the back of my hand.

It spread lightly when I smoothed it on with my fingers. After cleansing, I felt almost no sticky residue or oily sensation. For me, it left a hydrated finish.

How did I use it in my morning and evening skincare routine?

After cleansing with a mildly acidic cleanser, I used a watery toner to refine my skin texture, then applied the serum. I placed one drop each on both cheeks and my forehead, spread it along my skin texture, and finished with the hydrating or moisturizing cream I normally use.

In the morning, I used it before makeup. In my experience, it did not pill or cause my makeup to slide. I also used it to leave my skin hydrated and smooth before foundation.

What were the drawbacks of the size while using it?

The bottle contains 30ml. The dropper bottle was easy to use, but I felt that one bottle could be finished in around a month if applied generously to both cheeks, the forehead, and the neck morning and night. I was left wishing there were a larger-size option.

I also used sunscreen as the last step of my morning routine. Skin condition and product feel vary from person to person, so it is best to watch how your own skin responds when using a new product.
