Choosing the appropriate sunscreen is vital for safeguarding our skin against the detrimental effects of ultraviolet (UV) radiation.Recent research indicates that many consumers in the UK lack accurate information regarding sun protection, highlighting a significant need for education on preventing sun-related skin damage.
With a multitude of products available, making an informed choice can be a challenge.
Therefore, NATRUE provides four essential guidelines to consider before purchasing a natural sunscreen, grounded in the principles of the NATRUE standard for natural and organic cosmetics.
1.
COMPREHENDING SPF AND BROAD-SPECTRUM DEFENSE It is crucial to recognize that UV rays come in two forms: UVA and UVB.
A handy way to recall their effects is by associating “A” with “Aging” and “B” with “Burning.” While UVA rays may not leave visible marks, they trigger existing pigment in the skin, resulting in a temporary tan, yet they are linked to premature aging and various skin issues.
Conversely, UVB rays are responsible for sunburn by penetrating deeper into the skin, leading to cellular damage and an increased risk of skin cancer. The sun protection factor (SPF) indicates how well a sunscreen protects against UV rays, primarily UVB.
Contrary to common misconceptions, a higher SPF signifies greater protection but does not determine how often or how long you need to reapply the product.
For instance, an SPF of 50 theoretically prolongs the time before skin begins to burn by fifty times compared to unprotected skin, reinforcing the necessity of proper application. To make a wise choice, select a sunscreen that matches your skin type and level of sun exposure.
It is advisable to apply sunscreen 20-30 minutes prior to sun exposure and to reapply regularly, particularly during peak sun hours, typically between 11 AM and 4 PM.
Additionally, when caring for infants or young children, it is vital to limit their sun exposure and utilize a high SPF sunscreen (such as SPF 50) when they are outdoors.
2.
OPTING FOR NATURAL INGREDIENTS There are two categories of UV filters in sunscreens: chemical and mineral, which can be used alone or in combination. – Mineral (or “natural”) filters act as a barrier on the skin, blocking UV rays from penetrating.
They function by reflecting UV radiation, resulting in a “screen-like” effect. – Chemical filters are derived from petrochemicals and work by absorbing UV rays into the skin and converting them into heat. When selecting a product, examine the ingredient list carefully.
Conventional sunscreens may contain substances like benzophenone-3 and octocrylene, which are emerging pollutants.
In contrast, natural sunscreens, particularly those with NATRUE certification, exclusively use mineral filters such as zinc oxide or titanium dioxide.
If you seek a natural sunscreen, you can refer to NATRUE’s database to find products compliant with the NATRUE Label criteria, which ensures the formulation is genuinely natural or organic.
3.
EFFECTIVENESS AND WATER RESISTANCE The efficacy of sunscreen not only depends on its SPF rating but also on its longevity while on the skin during sun exposure.
According to EU Cosmetics Regulation, claims made by products must be backed by data to prevent misleading consumers, meaning any assertion of long-lasting protection, including against moisture and water activities, needs to be scientifically validated. For practical use, water resistance is essential, particularly if engaging in swimming, outdoor activities, or sweating heavily.
A water-resistant sunscreen offers prolonged protection on the skin.
Remember to apply sunscreen thoroughly to often-neglected areas such as ears, feet, and ankles. 4.
APPLICATION AND TEXTURE
NATRUE emphasizes that the sunscreen’s texture and the ease of application play a significant role in encouraging consistent use.Sunscreen formulations are available in various formats, including lotions, gels, sprays, and sticks, each catering to different preferences and situations. When selecting a sunscreen, prioritize ease of application, especially for frequent reapplication or in settings where applying sunscreen may be challenging, like at the beach. Choosing the right sunscreen is vital not only during the summer months but throughout the entire year, given that UV rays are always present.
While higher SPF sunscreens are recommended for summer use, there are suitable options with lower SPFs, like day creams, available for winter that continue to protect your skin.
