The burning sensation on the face when applying aloe vera gel may be caused by excessive dryness of the skin, or it may be due to factors such as skin injury and allergy.

1. Dry Skin: Dry skin usually leads to severe water loss, with small cracks often appearing on the skin. Applying aloe vera gel can cause the skin to be stimulated, resulting in a burning sensation. If it is not particularly serious, it can continue to be used, and it is also recommended to use hydrating masks frequently to help alleviate dry skin.

2. Skin Injury: If there is obvious外伤 on the skin, applying aloe vera gel can also stimulate the wound, causing a burning sensation. It is necessary to wash off the aloe vera gel, then use iodophor for local disinfection, and also apply drugs such as erythromycin ointment to promote recovery.

3. Allergy: If you are allergic to aloe vera gel, an allergic reaction may occur after application, causing a burning sensation on the skin and accompanied by itching or swelling. It is necessary to stop using aloe vera gel and take antiallergic drugs such as loratadine tablets or cetirizine hydrochloride tablets under the guidance of a doctor for treatment.

Aloe vera gel usually has certain benefits for the skin, which can improve dry skin or fade spots, but attention must also be paid to the correct method of use.
