. People with seborrheic dermatitis produce too much sebum (the natural skin oil). Later, pityrosporum yeast grows excessively in the sebum, sometime along with bacteria, making the dermatitis more persistent.
Take some oral antihistaminic and avoid using any eye cosmetics. If the symptoms persist then please get it evaluated for seborrheic dermatitis and the medical conditions mentioned above.
I hope it helps. Take care and please do keep us posted on how you are doing.
