Who Should Buy This
This serum is perfect for anyone who wants brighter and more even skin. If you have dark spots, uneven skin tone, or dullness, this product can help improve your skin’s appearance. It is also great for people who want to add hydration and protection to their daily skincare routine. The combination of niacinamide, vitamin C, hyaluronic acid, and vitamin E works well for most skin types, especially normal to dry and combination skin.
However, if you have very sensitive skin or allergies to any of the ingredients like vitamin C or niacinamide, you should be careful. It is best to do a patch test first or avoid this serum if your skin reacts easily. Also, if you have oily or acne-prone skin, consult with a dermatologist before use to make sure it suits your skin needs.

Our Testing Experience
First Impressions
When I first tried the EQQUALBERRY Vitamin Illuminating Serum, I was curious about its natural Vitamin C content and how it would feel on my skin. The serum had a light, refreshing texture that absorbed quickly without leaving any sticky residue. The packaging was compact and easy to handle, which made it simple to apply the right amount each time. I was excited to see if it would really give my skin that “glass-like” glow it promised.
Daily Use
Using the serum every morning and night became a nice part of my skincare routine. I noticed that it didn’t irritate my sensitive skin, which was a big plus. The light scent was pleasant but not overpowering. After a few days, my skin started feeling smoother and looked a bit brighter. I especially liked how it layered well under my moisturizer and makeup without causing any pilling.
Key Features in Action
The combination of Niacinamide 4% and Arbutin 2% really stood out to me. I have some dark spots and uneven skin tone, and over time, I noticed those areas becoming less noticeable. The Vitamin E and Ferulic Acid seemed to help with keeping my skin feeling soft and hydrated, while the Tranexamic Acid appeared to support a more even complexion. Overall, the serum felt like it was doing a good job at brightening and improving my skin’s texture.
Long-Term Performance
After using the serum consistently for about a month, my skin looked healthier and more radiant. The dark spots had faded slightly, and my overall skin tone was more even. I also felt that fine lines around my eyes looked a bit smoother, which was a nice bonus. The serum kept my skin hydrated without feeling heavy, making it a great addition to my daily routine. I would definitely recommend it to anyone looking for a gentle but effective brightening serum.
