Hello, Thank you for posting on HCM. It seems you have Atopic diathesis. Dry itchy skin and under eye dark circles suggest you have were sensitive skin. For Dry skin, make sure you apply good quality moisturizing cream like Cetaphil Restoraderm twice a day. Also apply tacrolimus 0.03% lotion over itchy areas at night on regular basis. Dark circles under eyes or under eye pigmentation is a challenging condition to treat. Its seen commonly in people having stressful life and irregular sleep and diet. Its also seen among people having atopic dermatitis and asthma. Sometimes its genetic due to deep sunken eye sockets in skull. Most of the OTC products are not very useful. I would advise you to apply tacrolimus 0.03% ointment at night and AVARTA eye cream twice a day. Take oral Vit C regularly. Additionally, a series of chemical peels like arginine, lactic acid etc from a certified dermatologist can help alot. Try to de-stress your life and maintain a healthy schedule. Hope you will be fine Take care Dr Hardik Pitroda
