COSMECEUTICAL SERUM VITAMIN B3 +

$99.00

A daily serum that brings skin back into balance

Redness looks quieter, blemishes feel less dominant, and the complexion starts to appear more even and settled. That is what makes Vitamin B3+ such a strong daily step. It supports the kind of skin that looks calmer, clearer, and healthier overall, without making the routine feel complicated or heavy.

Built around barrier strength and visible clarity

Cosmeceutical Serum Vitamin B3+ is the 2024 Prevention Beauty Award winner for Best Vitamin B Serum, supporting skin where it often needs the most help. Niacinamide helps strengthen the barrier and improve moisture retention, while peptides support smoother skin and overall skin function. Together, they help reduce the look of redness, pigmentation, and uneven tone while keeping skin feeling comfortable and supported.

The proof is in how many concerns it can quietly improve

Some serums feel impressive for a week, then fade into the background. This one tends to do the opposite. Because it is well tolerated and easy to use every day, it becomes the step people keep reaching for. Over time, that consistency helps skin feel stronger, look clearer, and stay more balanced, especially when it is prone to sensitivity, reactivity, or visible fluctuations.

I am currently travelling so packed light. Just my cleanser, B3, A and moisturiser all from MX. I suffer from Rosacea and normally after a walk in the sun my cheeks would be red!! My left cheek has always been the worst one. But the other side I’m super happy with.
I’ve been using these products for approx a month.

A game changer for dry, hormonal, perimenopausal skin
I’ve tried countless skincare products over the years, but the MX Vitamin B3 serum has truly stood out—especially now that I’m navigating the skin changes that come with perimenopause.
After just a couple of weeks of using the serum, I noticed a significant improvement. My skin feels more balanced, smoother, and deeply hydrated without feeling greasy or heavy. I’ve got my glow back. 🌟
