there is a very easy remedy to follow for gaining a better complexion.
in the nights, apply the gel of fresh aloe-vera leaves to your face n wash it vd normal water in the morning. also u can apply to any black spotted area in your body. use as many days u want. it improves skin tone, removes black spots, blach/ white heads, dark circles too.
also avoid chemical soaps. better use herbal bath powder. also apply fenugreek seeds powder (menthulu powder), mix it with water/ rose water/curd as face packs.
note :for even complexion, whatever u r using for face, apply it to the sun exposed parts like neck, hands etc.
for weight gain : take a spoon of AJAMAMSA RASAYANAM, mix it in a glass of luke warm milk n consume. it can put on weight atleast from 3-5kilos a month, depending on body type.
MIND U take luke warm milk only els milk will be broken by which the medicine doesnt effect u.
