What’s All the Fuss About Sunscreen?

  1. UVB are short high-energy wavelengths that damage the first layer of your skin (epidermis) and can cause:
  • Irritation
  • Sunburns
  • Some types of skin cancer
  • Hyperpigmentation
  • Long-term damage to DNA
  • Premature aging (wrinkles and saggy skin)
  • Immediate darkening of skin
  1. Chemical sunscreens are those that contain synthesised chemicals like oxybenzone and they work by absorbing UV rays, converting it to heat and releasing it as infrared rays. They are lightweight and easily reapplied during the day. They also layer more seamlessly under makeup but can be irritating, especially to sensitive skin.These take 20 minutes after applying to start working as they need to be absorbed first.
  2. Physical sunscreens use natural minerals like zinc and titanium oxide which leave a white cast on the skin.These active minerals sit on top of the skin to reflect incoming UV rays and they work immediately after applying. It is better for sensitive skin but it’s a little heavier and more visible on the skin which means it’s not as easy to layer under makeup or reapply.
