Here are the key points about sunscreen, SPF levels, application frequency, ingredients to avoid, and recommended ingredients to look for:
Importance of wearing sunscreen:
Protection against harmful UV rays: Sunscreen helps shield your skin from the damaging effects of ultraviolet (UV) radiation, which can cause sunburn, premature aging, and increase the risk of skin cancer.
SPF (Sun Protection Factor) levels:
SPF 30: Offers moderate protection by blocking approximately 97% of UVB rays. It is suitable for daily use, especially for activities with limited sun exposure.
SPF 50: Provides high protection by blocking about 98% of UVB rays. It is ideal for extended sun exposure, outdoor activities, and for people with fair or sensitive skin.
SPF 100: Provides the highest level of protection by blocking about 99% of UVB rays. However, the increased protection is only marginally higher than SPF 50, and SPF 100 is not significantly more effective than SPF 50.
Application frequency:
Apply sunscreen every two hours, or more frequently if you are swimming, sweating, or wiping your face with a towel.
Ingredients to avoid:
Oxybenzone: Some studies suggest it may disrupt hormones and cause skin allergies.
Octinoxate: It can harm coral reefs and has potential hormone-disrupting effects.
Recommended ingredients:
Zinc oxide: Provides broad-spectrum protection against both UVA and UVB rays. It is generally safe and suitable for sensitive skin.
Titanium dioxide: Offers similar broad-spectrum protection as zinc oxide and is also gentle on the skin.
Examples of sunscreens with recommended ingredients:
Neutrogena Sheer Zinc Dry-Touch Sunscreen SPF 30 or SPF 50: Contains zinc oxide and is suitable for sensitive skin. Generally this brand has great sunscreens
La Roche-Posay Anthelios Mineral Sunscreen SPF 50: Contains titanium dioxide and is also safe for sensitive skin.
C. Skin Ceuticals – there sunscreen range is great
Remember, it’s important to choose a sunscreen that suits your skin type and preferences. Additionally, wearing protective clothing, seeking shade, and avoiding excessive sun exposure during peak hours (10 am to 4 pm) are also important for sun safety preventing premature ageing. Basically it keeps your skin looking younger.
