Mixing Sunscreen Products: Does It Improve UV Protection?

Potential Risks of Mixing Sunscreen Products

According to Shin Ki-ok, a professor at the Department of Beauty and Cosmetic Science at Eulji University, mixing and applying multiple sunscreen products does not actually improve UV protection. In fact, it may lead to skin irritation.Professor Shin explains that sunscreens contain various chemicals and additives tailored to the characteristics of each formulation. When these products are used together, the combination can cause dermatological problems, such as:

  1. Maloka Acne: Also known as sunscreen-induced acne, this occurs when sunscreen ingredients stimulate pores that are activated by direct sunlight.
  2. Contact Dermatitis and Allergies: Certain ingredients like PABA are known to cause these skin issues.
  3. Increased Skin Sensitivity: Organic sunscreens without a white cast are more vulnerable to causing skin problems compared to inorganic sunscreens with a white cast.

Choosing the Right Sunscreen

To protect your skin effectively, Professor Shin recommends the following:

  1. Consider Your Skin Type: If your skin is dry, choose a balm or cream formulation. For oily skin, an oil-free lotion is better.
  2. Opt for Sensitive Skin-Friendly Options: For babies and those with sensitive skin, use less irritating, inorganic sunblock products, even if they leave a white cast.
  3. Reapply Frequently: It’s wiser to reapply SPF 30 or higher sunscreen products frequently rather than using very high SPF products.
  4. Properly Remove Sunscreen: Use a special cleanser to thoroughly remove sunscreen after use.

By following these guidelines and avoiding the practice of mixing multiple sunscreen products, you can ensure your skin stays protected and healthy.
