Nicotinamide

100% natural certification

Nicotinamide helps reduce Immuno-suppression induced by UV radiation. This immuno-suppression, which in turn promotes skin cancer, is one of the main reasons we are all encouraged to wear sunscreen when outdoors and exposed to the sun's UV rays.

However, sunscreens are relied primarily on preventing sunburn rather than preventing immuno-suppression or even in increasing ones own immunity levels.

When applied topically, nicotinamide, commonly known as Vitamin B3, has properties that inhibit immuno-suppression and thereby inhibits skin cancer. It actually acts as a chemo- and radio-sensitizing agent by enhancing tumour blood flow, which reduces tumor hypoxia, the condition through which tumour cells are deprived of oxygen. 

Added to a sunscreen, nicotinamide provides a powerful combination of protection from the sun's potentially harmful UV rays.

Including nicotinamide (Vitamin B3) in our sunscreens adds a powerful combination of protection through its abilities to:

  • act as a powerful antioxidant 
  • rejuvenate the skin, helping to promote the turnover of new skin cells
  • repair sun damage  
  • strengthen the skin’s moisture barrier
  • be active in more than 50 metabolic functions in your body, helping to produce energy by breaking down carbohydrates.
  • aid digestion and helps eliminate toxins
  • be vital to energising and maintaining healthy cells of all kinds

Topical nicotinamide (Vitamin B3) is also extremely effective in reversing signs of ageing in the skin by:

  • increasing blood flow - dilating the capillaries to allow more oxygen and other nutrients to flow to your skin
  • stimulating DNA repair, generating new, healthier skin cells and helping your skin look and feel younger
  • decreasing dark spots and increasing skin lightness, being the most visible signs of ageing
  • helping boost hydration through increasing the production of ceramides, which are skin lipids that retain water and prevent the loss of moisture 
  • cooling inflamed skin, including inflammatory acne, atopic dermatitis and rosacea
  • improving skin yellowing or sallowness 

In addition to this, Nicotinamide (vitamin D3) has demonstrated anti-inflammatory actions of benefit to people with inflammatory skin conditions such as acne vulgarise, showing an ability to block the inflammatory actions of iodides, which are known to precipitate or exacerbate inflammatory acne.
