SPF or the Sun Protection Factor is an index to measure how powerful a Sun Protection cream is! Sun Protection Creams should be used regularly to avoid sunburns and damage caused to the skin due to the exposure to UV rays. Using sunscreen is a wise decision to maintain the overall health and aesthetics of your skin. The SPF factors available in creams and lotions in varied proportions help to withstand different levels of sun damage.
Sun Protection creams with different levels of SPF suggest that the treatment and approach vary depending on the overall health of your skin.
- SPF 15 blocks 93% of UVB rays
- SPF 30 blocks 97% of UVB rays
- SPF 50 blocks 98% of UVB rays
Important Notes:
- SPF numbers don’t indicate how long you can stay in the sun, but rather the amount of UV radiation protection
- The American Academy of Dermatology recommends using at least SPF 30 daily on exposed skin
- Higher SPF provides only marginally better protection after SPF 30, though it may still be beneficial for some people
- For best protection:
- Apply sunscreen 15 minutes before sun exposure
- Reapply every 2 hours
- Reapply after swimming or sweating
- Look for “broad spectrum” protection for both UVA and UVB coverage 1
Remember: Regardless of SPF level, proper application and regular reapplication are crucial for effective sun protection.
Why should Sun Protectors be used on a regular basis?
1) Protection against Sunburns: Constant exposure to sun can result in radical skin damage causing redness, pain and signs of hyperpigmentation on your skin. It can turn out to be crucial for people having sensitive skin. Sunscreens act as a mask to your skin, filtering out the UVs.
2) Safeguarding your skin from UV rays: Sunscreen acts as a shield protecting your skin from harmful UV rays. It prevents the penetration of ultraviolet rays that bring about breakage in the cells resulting in DNA mutations. Regular use of SPF helps to block the penetration and absorption of the UV rays.
3) Reducing risks of Skin Cancer: UV rays are a key element in causing basal Skin Cancer, Squamous skin Cancer and Melanoma. SPF 15 reduces the chances of Squamous Cell Carcinoma by 15% and Melanoma by 50%.
4) Anti-Aging: Sun damage results in premature aging. UV radiation results in breakdown of Collagen and Elastin making the skin lose its firmness and elasticity. It leads to wrinkles, fine lines and age spots. SPF helps to minimize the chances of aging by acting as a barrier to UV exposure.
5) Maintaining the Facial Texture: Use of SPF helps to maintain the facial tone. It provides protection against the glaring effects of UV rays and cell damage, imparting an even tone to your skin.
For better skin protection and anti-aging, botox treatment, especially facial botox treatment can be highly beneficial. If you are looking for facial botox treatment in Mississauga, BO&FILL could be you good find.
