Hi, Thanks for asking. I understand your concern. Dry skin can be caused by very cold or hot season.low humidity in atmosphere. Apart from thease aging ,diabetes ,hypothyroidism can cause it *Basically using very hot or cold atmodpherer ,avoid frequent bathing,using strong soaps or sanitisers are personsl things one can avoid.. Frequent use of moisturizers,use of lip balms would ease it. Drinking plenty of water,fruit juices .Suplimentation of diet with vitamin A,E ,B complex &Ccan add to skin health. *Check ups,investigations to disgnose &get adequet specific treatment for diabetes,hypothyroidism may be needful . Thanks.
