What Should I Look for in a Sunscreen?
Always choose a sunscreen that is ‘Broad Spectrum’. This means that you are protected against both UVA & UVB rays, the two types of Ultraviolet (UV) radiation that reach the earth’s surface. If you plan to swim or sweat whilst outdoors, it is important also to choose a water resistant sunscreen and re-apply it as directed on the bottle. Where possible, use a sunscreen with a high sun protection factor of 30 or above, although an SPF15 sunscreen is better than none at all. Sunscreens are either a ‘physical’ or ‘chemical’ barrier sunscreen, with zinc oxide/titanium-based sunscreens falling into the former category and chemical sunscreens falling into the latter. Sensitive skin tends to require ‘physical’ barrier sunscreens.

What is the difference Between UVA & UVB Rays?
The various wavelengths of ultraviolet radiation are classified into three categories – UVA, B and C.
- Longer rays which penetrate the deepest into the skin (the dermis).
- Comprises 95% of the sun’s rays reaching earth
- Responsible for ageing (due to collagen destruction)
- Can cause skin cancer (benign and malignant)
- Suppresses the immune system of the skin making us more prone to skin cancer
- Can penetrate glass
- Is constant in intensity throughout the day and seasons.
- Shorter rays which penetrate only the surface layer of the skin (epidermis)
- Causes skin to burn
- Most intense between 11am and 2pm
- Absorbed by the ozone layer, these lethal rays do not reach the Earth’s surface.
What Damage Are UV Rays Causing My Skin?
UV rays can cause :
- pigmentation and age spots
- fine lines, wrinkles and large pores as a result of collagen depletion
- skin cancers of all kinds
How Can I Protect Myself from UV Rays?
Always wear a hat (wide-brimmed if possible), sunscreen and sunglasses when outdoors, especially between the hours of 10am-4pm when the suns rays are at their most damaging.
