Sunny days are around the corner now that we are on the middle of spring. You must have big plans for the warmer days of the year, going to the beach, a park stroll, flying to a tropical paradise in Central America, perhaps. You probably already have everything ready, bathing suit, plane tickets and your phone charger. But there’s one more essential you can’t afford to forget—your sunscreen. The correct selection and use of sunscreen is essential to have a safe vacation, and every day outdoors activities, really.

The Correct Selection and Use of Sunscreen
Sunscreen is one of those essentials that must be carried everyday, everywhere we go.
However, many of us slap it on and hope for the best, not realizing that the way we choose and use sunscreen can mean the difference between a healthy glow and harmful damage.
You’re about to learn not only why sunscreen is crucial in preventing skin cancer and premature aging but also dispel common misconceptions and provide a guide to choosing and applying it correctly.
UV Radiation
UV rays, or ultraviolet radiation, are a form of electromagnetic radiation that comes primarily from the sun, although it can also be produced artificially by devices like tanning beds and certain types of lamps. UV radiation is divided into three main types based on wavelength:
- UVA (Ultraviolet A): These are the longest wavelengths within the UV spectrum and penetrate deep into the skin. They play a major role in skin aging and wrinkling, and although less intense than UVB, they are present with more or less equal intensity during all daylight hours throughout the year.
- UVB (Ultraviolet B): These have shorter wavelengths than UVA and are the main cause of sunburn. The intensity of UVB varies by season, location, and time of day, peaking during summer and around midday.
- UVC (Ultraviolet C): These are the shortest wavelengths and are completely filtered by the earth’s atmosphere; hence they do not reach the ground. UVC rays are the most dangerous type of UV radiation but are primarily of concern in artificial environments or from artificial sources.
Understanding Sunscreen Formulations
For many, a sunscreen is an item that is a last-minute buy at the register, when buying groceries for our next vacation getaway. But there’s more to sunscreen that we must understand first.
Chemical vs. Physical Sunscreens
Chemical sunscreens absorb UV radiation through their chemical ingredients like oxybenzone, while physical sunscreens, containing minerals such as zinc oxide or titanium dioxide, reflect UV rays.
Physical sunscreens are typically better for sensitive skin as they are less likely to cause irritation.
Natural Organic Options
These sunscreens use ingredients like zinc oxide and titanium dioxide and avoid potentially harmful chemicals, making them a good choice for environmentally conscious users.
Understanding the Sun Protection Factor -SPF-
 SPF, or Sun Protection Factor, indicates the level of protection against UVB rays.
For example, SPF 30 means it would take 30 times longer for your skin to burn than without any sunscreen. However, higher SPF numbers do not equate to a proportional increase in protection.
Selecting The Right Sunscreen for You
There are a few more details that you should know before your next sunscreen purchase.
Understanding Key Active Ingredients
Ingredients like avobenzone provide significant UVA protection, while zinc oxide offers extensive UVA and UVB coverage. These ingredients are crucial for effective sunscreen.
Beware of ingredients like oxybenzone and octinoxate, which are associated with coral reef degradation and may have hormonal effects in humans.
Selecting Sunscreen Based on SPF
- SPF 15: Blocks about 93% of UVB rays. Suitable for everyday use for people with darker skin tones or for short periods outdoors. It provides minimal sun exposure protection and is not recommended for prolonged outdoor activities.
- SF 30: Blocks about 97% of UVB rays. Recommended for daily use for all skin types. It provides good protection for moderate exposure, such as during a typical workday that might include brief intervals outside.
- SPF 50:Â Blocks about 98% of UVB rays. Ideal for extended outdoor activities such as hiking, sports, or beach days. It’s especially recommended for individuals with fair skin that burns easily.
- SPF 70+: Blocks about 98.5% or more of UVB rays. Best for very sensitive skin types, children, or for situations involving intense sun exposure, such as at high altitudes or tropical locations. Also useful for those with a history of skin cancer or genetic predispositions to skin health issues.
The right SPF for you depends on your skin type, the intensity of the sun exposure, and the duration of your time outdoors. Always consider these factors when choosing a sunscreen to ensure adequate protection.
Selecting Sunscreen Based on Skin Type Condition
- For Sensitive Skin: Choose mineral-based formulations that are fragrance-free and hypoallergenic.
- For Acne-Prone Skin: Look for labels like ‘non-comedogenic’ to ensure the sunscreen won’t clog pores.
- For Aging Skin: Some sunscreens include antioxidants such as vitamins C and E, which can help prevent the aging effects of the sun.
- For Children’s Skin: Use mineral-based sunscreens as they are less likely to irritate the skin and are safer for young children.
Sunscreen in Various Settings
- Everyday Use vs. Extended Outdoor Activities: Daily moisturizers with SPF are sufficient for short periods outdoors, but water-resistant, high-SPF sunscreens are crucial for extended outdoor activities.
- Water-Resistant Formulas: These are essential if you’re swimming or sweating. Remember that ‘water-resistant’ does not mean ‘waterproof,’ and reapplication is necessary.
Broad Spectrum Protection
Look for sunscreens labeled ‘broad-spectrum’ for protection against both UVA and UVB rays. UVA rays are primarily responsible for aging the skin, whereas UVB rays cause sunburn. Both can lead to skin cancer.
How to Properly Use Sunscreen
- Use the UV index to guide your sun protection choices, with higher indices requiring more stringent protective measures.
- Apply daily and accordingly to the type of activities that you will have throughout the day. Re-application may be necessary if exposed to sunlight for extended periods of time.
- Check the key components on the label of the sunscreen to identify any harmful to your specific skin type.
- Combine sunscreen with UV-protective clothing and sunglasses for optimal protection.
The Bottom Line
Protecting your skin from the sun is not just about avoiding a sunburn. Proper selection and application of sunscreen can significantly reduce the risk of skin cancer and prevent premature aging.
Isn’t it worth taking a few extra minutes to ensure you’re fully protected?
