What should I do about red skin on my face?

1. If skin redness is caused by thinning of the stratum corneum, it is recommended to avoid excessive exfoliation and using harsh facial cleansers; instead, choose mild, non-irritating skincare products. Eating more high-protein foods can help promote repair of the skin's stratum corneum. 2. Under medical guidance, antiallergic medications such as loratadine hydrochloride capsules or cetirizine hydrochloride tablets may be used for treatment. 3. Environmental factors may also cause facial skin redness. For example, prolonged exposure to cold or hot environments may lead to dilation of facial capillaries, resulting in red skin.
