What do B vitamins help retain in the skin according to suggested treatments?

B vitamins play a crucial role in maintaining skin health by helping to retain moisture. This is particularly important because adequate moisture levels are essential for the skin's barrier function and overall appearance. When skin is well-hydrated, it appears plump and youthful, whereas dehydrated skin can lead to dryness, flakiness, and the development of fine lines and wrinkles.

B vitamins, such as niacinamide (Vitamin B3) and panthenol (Vitamin B5), are known for their hydrating properties and ability to improve the skin's barrier function. They can increase the skin’s water content and help it retain moisture, thereby improving its overall texture and appearance. This moisture retention is integral to maintaining a healthy complexion and can support the skin in looking vibrant and youthful.
