Vitamin B 30ml

Sale price$90.00

Boost your skin's defense with Vitamin B - the key to a robust and resilient skin barrier. When your skin's protective barrier is fortified, it effectively blocks harmful invaders like bacteria, free radicals, and environmental pollutants. This is especially crucial for those with sensitive skin, as it minimizes irritation and sensitivity. Moreover, Vitamin B plays a pivotal role in maintaining your skin's hydration levels, resulting in a plump, voluminous appearance that radiates health and vitality.

Our Vitamin B collection is designed not only to strengthen your skin's barrier but also to enhance its natural beauty, leaving it looking radiant and full of life. Dive into our range of Vitamin B-enriched skincare products and experience the difference in your skin's texture and overall appearance. Ideal for sensitive skin types, our formulations are gentle yet effective, promising visible results that include a more luminous complexion and a stronger, more resilient skin barrier.

I try EVERYTHING and this is quite possibly the best product I have ever used on my skin. It refined the texture of my skin and make my make up sit perfectly.


Beautiful serum that makes skin feel hydrated


I have only been using this product for about 3 weeks so may be a bit too early to give 5 stars. I do think it's helping to reduce redness though which is always nice 😊


I’ve gone back to this V B - it’s better on my sensative skin


So so good
