The Science of Sunscreen & Why It Is Important?

Blogs Main Banner (4)You've probably heard us stress the importance of SPF countless times, but have you ever wondered what SPF actually means? SPF stands for "Sun Protection Factor," followed by a number like 30 or 50. When we plan to spend time outdoors, we apply sunscreen generously to prevent sunburn, but once we're back to our daily routines, SPF often slips our minds. So, do we need sun protection all year round? And if so, how much sunscreen should we apply to our body and face?

What Are UV Rays?

When considering sun protection, it's crucial to focus on UV rays rather than just the heat. Here's why:
The sun emits various types of energy: infrared radiation, which we feel as heat; visible light, which we see as sunlight; and ultraviolet (UV) radiation, which we cannot see or feel.

  • UVA Rays: These rays penetrate the Earth's atmosphere easily and reach the surface.
  • UVB Rays: Only a portion of UVB rays make it through the Earth's atmosphere; the rest are absorbed by the ozone layer.
  • UVC Rays: These rays are completely absorbed by the ozone layer and do not reach the Earth's surface.

Of these UV types, UVA and UVB rays are the ones that contribute to skin cancer, sunburn, premature aging, and eye damage. UV rays can also penetrate windows, so even if you're indoors, you’re still exposed to them.

What Is Broad-Spectrum Sunscreen?

Broad-spectrum sunscreen offers protection against both UVA and UVB rays. UVB rays are known for causing sunburn and are more strongly linked to skin cancer. UVA rays, on the other hand, are primarily responsible for premature skin aging but can also contribute to some types of skin cancer. Using a broad-spectrum sunscreen ensures you’re protected from the harmful effects of both types of UV radiation. Here are the top 2 SPF that can treat and protect your skin, to keep younger skin as we age.
