Doctors can you tell me why is my face burning when i apply moisturizer?

If it burns avoid it: Common moisturizers contain additive compounds and preservatives which your skin may be sensitive to. A better choice is to pick a moisturizer for sensitive skin, a hypoallergenic moisturizer, or a single compound moisturizer such as 5% hyaluronic acid which is commonly sold in holistic vitamin shops/pharmacies. Hyaluronic acid is a natural component of the skin which hydrates the skin.
