Why does my face hurt after washing it?

Generally, facial pain after washing the face may be caused by factors such as water that is too hot, irritation from facial cleansers, damaged skin barrier, contact dermatitis, or seborrheic dermatitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under a doctor's guidance. Specific analysis is as follows:

1. Water temperature too high: Washing the face with water above 40°C can disrupt the skin's natural oil layer and damage the stratum corneum, leading to pain. Immediately rinse the face gently with lukewarm water, and subsequently keep the washing water temperature between 32°C and 35°C—close to skin temperature—for a gentler experience.

2. Irritation from cleansers: Facial cleansers containing ingredients like soap base or alcohol can over-cleanse the skin, causing irritation and pain. Discontinue use of the irritating product and switch to a gentle cleanser based on amino acids or glucosides. Avoid excessive rubbing during washing.

3. Damaged skin barrier: Frequent exfoliation or over-cleansing can thin the skin’s protective barrier, resulting in stinging and redness after washing. Patients may follow medical advice to use medications such as recombinant human epidermal growth factor gel, ceramide lotion, or vitamin E cream. Reduce frequency of face washing and avoid makeup application.

4. Contact dermatitis: Allergic reactions to ingredients in facial cleansers or water can cause pain, itching, and red rashes after washing. Immediately discontinue use of the allergenic product and thoroughly rinse with clean water. Follow a physician's instructions for using antihistamines such as cetirizine hydrochloride tablets, loratadine capsules, or ebastine tablets.

5. Seborrheic dermatitis: Inflammation caused by excessive sebum production can lead to pain upon stimulation during washing, accompanied by oily scales. Patients should use medications such as tacrolimus ointment, pimecrolimus cream, or ketoconazole cream as directed by a doctor, and choose mild, oil-controlling facial cleansers.

After daily face washing, gently pat the skin dry with a clean towel and immediately apply a gentle moisturizer to lock in hydration. Avoid frequent use of exfoliating products and harsh skincare items. In terms of diet, reduce intake of spicy and irritating foods, and increase consumption of vitamin-rich fruits and vegetables to support skin recovery.
