The type of sunscreen you require depends on the kind of outdoor exposure you are about to have. It can be incidental or intense where in incidental the period is shorter requiring a sunscreen of SPF 15 but for severe exposure you need a sunscreen of SPF 30+. If you are planning to go swimming, you need a water-resistant sunscreen with an SPF of 30+.
For how long can you stay in the sun without getting sunburn wrinkles? It is the influence of Sun protector factor (SPF). Sunscreen provides the degree to which a sunscreen protects the skin from the direct rays of the sun. SPF is tailored specifically to ensure maximum exposure to sunlight for very long time. Here are some facts you should know about sunscreen protector factor -SPF:
1. Use a sunscreen with SPF of 15+ to increase the time by a factor, meaning that it increases protection when the exposure to sunlight goes on for long periods.
2. A sunscreen with high SPF blocks out more UVB rays. Therefore, it cuts down the absorption of free radicals in the body through the skin.
3. When you apply sunscreen wrongly or unevenly, its effectiveness reduces. When sweat or rain is in contact with the skin, the sunscreen washes away, and its SPF greatly diminishes.
4. SPF only blocks UVB rays but not UVA rays hence solar radiation is absorbed into the skin causing rapid growth of cells leading to the development of cancerous tissues. Also chemical substances used in sunscreens are used to block UVA rays radiation such as zinc oxide and titanium dioxide but also pose health risks such as cancer.
5. Sunscreen SPF is not an option of staying longer in the sun. You can boost your SPF by wearing covered cloth. Exposure to UV rays can lead to unforeseen medical conditions. In similar people with gene makeup related to skin cancer in the family tree are greatly at risk when they are get exposed to the sun for too long.
Sunscreen for your skin type
Sunscreens for babies and children
Children have sensitive skin, therefore, react to sunscreens with PABA and oxybenzone but react less to physical sunscreens with ingredients such as zinc oxide and titanium dioxide. It is not easy to get kids and babies to use sunscreen lotion, but misting sprays in your hand would do or tubes with colorful packaging.
Allergy, acne, and rosacea-prone skins
Allergy-prone users should not apply sunscreens with alcohol ingredients nor preservatives and fragrances. Those sunscreens with ingredient PABA and Oxybenzone are not any better option. Acne-prone people should avoid oily sunscreens as this would aggravate their situation.
Sunscreen for dry skin
People with oily skin require sunscreens with moisturizing ingredients such as lanolin, oils, silicone such as dimethicone.
For individuals with fair skin, melasma, or a history of skin cancer
A person with fair skin, melasma or history of skin cancer needs to take care of themselves when under the sun. They need sunscreens with SPF of 30+ rating apart from that they should apply enough sunscreen to achieve what the label indicates to get full protection. They need to reapply the sunscreen every 2 two hours if the exposure is longer. If you have blotchy brown discoloration skin called melisma, you need extra protection too.
Darker skin tones
Dark-skinned people should be weary of physical sunscreen such as titanium-based that looks chalky and white on the skin on another hand they may find a broad spectrum option with SPF 15+ sunscreen.
For older people sunscreen
Older people too need protection as much as they already have exposure to UV light unprotecting their skin exposes them more to skin cancer. UV light accelerates aging and appearances of aging spots, sagging skin and wrinkles.
Conclusion
Safe sunscreen for your skin requires one to select the right sunscreen SPF. To have a healthy skin and boost your sun protector factor (SPF), wear sun-protective clothing. Try other ways by lotion up regularly and wearing sunglasses. Above all, you should check your skin regularly to detect any change in your skin color and presence of dark spots to determine the factor sunscreen SPF to use and apply on the skin.
Sunscreen is an important sun regimen but should go hand in hand with educating yourself about sunscreen options available in the market. Wear clothes that protect the skin from harmful UV light when going out in the sun, seek shade, avoid UV tanning and wear UV-blocking sunglasses.
Protect your lips from sunscreens by applying a lip balm before using a sunscreen Apply the sunscreen as instructed on the product label to avoid under application because you should coat all the areas that get exposed to the UV light. A broad spectrum sunscreen offers better protection against UVA and UVB rays, therefore, check before purchasing. Seek advice from dermatologists if you realize a problem with your skin after using a sunscreen.
