In the previous article, we talked about how the skin reacts when UV rays hit the skin. Resulting in skin pigmentation, read our article (Skin Pigmentation Treatment). Now, let’s take a step back to understand more about UV rays.
What is UV?
The sunlight that reaches us is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB).
UVB rays will usually burn the superficial layers of your skin. It plays a key role in the development of skin cancer. The intensity of UVB rays vary by season, location and time of day, with 10AM to 4PM being the peak hours. Sunburned skin doesn’t just feel awful, it can cause permanent damage over time.
UVA rays penetrate deep into the dermis, the skin’s thickest layer. It causes pre mature aging and wrinkles.
What is the suggested Sun Protection to Protect against UV rays?
The SPF factor rates how effective the sunscreen is in preventing sunburn caused by UVB rays. If you’d normally burn in 10 minutes, SPF 15 multiplies that by a factor of 15, meaning you could go 150 minutes before burning.
Keep in mind that the higher the SPF, the smaller the increased benefit: contrary to what you might think, SPF 30 isn’t twice as strong as SPF 15. While SPF 15 filters out 93% of UVB, SPF 30 filters out 97%, only a slight improvement.
The New Broad-Spectrum Sunscreens
So which is the best sunscreen for you? Clearly, you’ll want a sunscreen with broad-spectrum or multi-spectrum protection for both UVB and UVA. Ingredients with broad-spectrum protection include benzophenones (oxybenzone), cinnamates, sulisobenzone, salicylates, titanium or zinc oxide, avobenzone and ecamsule .
For kids and sensitive skin, we suggest to use sunscreen products with physical blockers eg., titanium or zinc oxide instead of chemical filters eg. benzophenones etc which react only when the UV rays hit the skin.
Our favourite sunscreens are
- Maria Galland SPF50, a translucent suncreen with moisturizing effects
- Guinot Brightening SPF50, which sun protects and help to brighten the skin with melanoxyl
- Jyunka SPF50, a slightly tinted sunscreen which also helps to even out uneven skin tone
