1. Blockage of pores: Excessive use of sunscreen may cause pore blockage, especially when the sunscreen is thick or contains a large amount of oil. This increases the risk of skin problems such as acne and pimples.
2. Affects skin respiration: The skin needs to breathe to maintain normal physiological functions. Excessive coverage of sunscreen on the surface of the skin may hinder normal breathing, causing the skin to feel stuffy and stuffy, and may damage skin health in the long run.
3. Increasing skin burden: Although sunscreen ingredients have a protective effect against ultraviolet rays, excessive use can also bring additional burden to the skin. Some sunscreen ingredients may cause irritation or allergic reactions to certain sensitive skin, resulting in symptoms such as redness, swelling, and itching. At the same time, frequent or excessive application of sunscreen may also interfere with the natural barrier function of the skin, making it more susceptible to external environmental damage.
