Summer Skin Guardian: Comprehensive sun protection strategy unveiled


In the hot summer, UV rays become more intense, and the work of sun protection becomes especially critical. Sun protection is not only about skin color, but also about skin health, and is an important means to prevent skin aging and disease. This article will delve into the importance of sun protection and provide comprehensive sun protection strategies to help you protect your skin effectively.

First, the importance of sun protection


  1. Resist light aging
Ultraviolet light is the main cause of skin exogenous aging, that is, photoaging. UVB and UVA can penetrate the atmosphere and act directly on the skin. UVB is the main cause of sunburn, while UVA is the main cause of skin tanning and aging. Long-term exposure will accelerate skin aging.

  1. Prevent stains and skin lesions
Ultraviolet radiation activates melanocytes in the skin, causing pigmentation and forming dark spots. At the same time, UV light is a key risk factor for non-melanoma skin cancer, and sun protection can effectively prevent these skin problems.

  1. Maintain healthy skin
Uv damage to the skin has a cumulative effect. If you do not take sun protection measures for a long time, your skin may suffer irreversible damage and increase the risk of skin cancer. Therefore, sun protection is a necessary measure to maintain skin health.

choose the right sun protection method


  1. Understand sunscreen product metrics
  • SPF value : indicates the UVB protection capability. A higher value indicates a longer protection period.
  • PA value : indicates the degree of protection against UVA, the higher the level, the better the effect of delaying tanning.
  • Critical wavelength : An indicator to measure the protection effect of UVA. The larger the value, the better the protection effect.

  1. Physical and Chemical sun protection
  • Physical Sun protection : Sun protection by reflecting UV rays, ingredients such as titanium dioxide and zinc oxide, suitable for sensitive skin, but may leave white marks on the skin.
  • Chemical sunscreen : converts ultraviolet rays into heat, light texture, suitable for general skin, but some people may be sensitive to its composition.

  1. Choose sunscreen products according to skin type
  • Sensitive skin : Choose non-additive, physical sunscreen products.
  • Dry skin : Choose a moisturizing sunscreen.
  • Oily skin : Choose a clear sunscreen to avoid oil clogging pores.

  1. Choose sun protection according to the event scene
  • Indoor : Choose a sunscreen with a low SPF.
  • Short time outdoors : Choose a sunscreen with medium SPF and PA.
  • Long time outdoors : Choose a sunscreen with high SPF and PA values, combined with physical sun protection


Use sunscreen properly


  1. Application time : Apply sunscreen evenly 30 minutes before going out.
  2. Dosage and uniformity : Ensure that sufficient amounts are used and all exposed areas are covered.
  3. Regular reapply : Reapply every two hours in outdoor activities.
  4. Thorough cleaning : Use appropriate cleaning products to ensure that sunscreen is thoroughly removed.

Year-round sun protection is a key step in keeping your skin healthy. The correct selection and use of sunscreen products can not only prevent tanning and sunburn, but also resist the deep damage of ultraviolet rays and prevent photoaging and skin diseases. Let's take active steps to protect ourselves from the sun and enjoy healthy and beautiful skin.
