With the coming of Fall, a series of conditions, such as temperature, humidity, sunlight, etc., have changed, making your sensitive skin feel uncomfortable and stressed out, even causing skin allergy. (That’s because airborne allergens such as bacterial spores and pollen release histamine, a compound found in almost all tissues of the human body, causing nasal congestion, sneezing, runny, itchy throat, swelling of the eyelids, and so on.) So it is necessary to adjust your skin care routine, and use gentle, safe, even non-fragrance products, avoiding causing burden for skin.
