Dull skin is the result of lack of proper skincare and healthcare. Even lack of water consumption, frequent sun exposure, clogged pores, dry skin, aging skin, going to sleep without removing makeup, no exfoliation or scrubbing or streaming, lack of balanced diet, sleeping disorders and stress all contribute to a dull skin.
Once identified, it is easy to treat a dull skin. There are a lot of options available, you can follow either natural ways or through skincare products. Both the methods work equally well.
Lifestyle changes can help, having a lot of water (6-8 cups of water a day), following a proper skincare routine which starts from face streaming, exfoliation, use of cleansers at night before sleep, facial mask, moisturizer when and where required, use of toners or astringents for those who require, use of sunscreen whenever necessary, allowing skin to fresh itself after a wash (with no makeup) to be devoid of all inhaled pollutions, skin residues and tiny dirts.
