Dull or lacklustre skin is most commonly caused by a build-up of dead skin cells and dry skin that is often caused by stress and not getting enough sleep.
Dull skin can not only look rough but can also prematurely age skin, while dead surface skin cells can prevent moisturiser reaching your new cell growth which is essential for a healthy glow. Stress can affect the appearance of the skin and can result in acne, or fine lines and wrinkles.
Exfoliating is an important part of your skincare routine as it removes the build-up of dead skin cells and helps cell turnover so that the skin looks more radiant. Not only does exfoliation unclogs pores, it increases circulation, and stimulates collagen synthesis (collagen production); it is essential at any age, but particularly as we age since dead skin cells accumulate due to our skin turnover slowing down.
