After my pregnancy I lost my weight too much and there is no glow left on my face what to do for gaining wt and restoring my facial glossiness?

Healthy diet, sleep! The sudden hormone changes after birth, a decrease in your iron stores, and lack of sleep all take their toll. A too rapid weight loss is a shock to the system. Try now to stabilize your weight. Hydrate like crazy, take a multivitamin with iron (prenatals are good) and gain a small amount back (if you think you need to) but also slowly, like a pound a week. For the face, exfoliate, peptides.
