Sun protection is one of the most important steps in any skincare routine. With prolonged exposure to UV rays, the skin is at risk of premature ageing, sunburn, and even skin cancer. Choosing the right sunblock Singapore ensures daily protection, keeping your skin healthy, smooth, and resilient. While sunblock is essential for outdoor activities, it is equally important for daily use, as UV rays can penetrate windows and affect the skin even indoors.
Understanding Sun Protection
Sunblock, or sunscreen, works by either reflecting or absorbing harmful UV rays, preventing them from penetrating the skin. It is typically categorised by its Sun Protection Factor (SPF), which indicates the level of protection against UVB rays, responsible for sunburn and skin damage. A higher SPF offers stronger protection, but it is also essential to consider UVA protection, which contributes to premature ageing and can penetrate deeper into the skin.
There are two main types of sunblock: chemical and physical. Chemical sunscreens absorb UV rays through active ingredients, while physical sunscreens, also called mineral sunscreens, create a barrier on the skin to reflect UV rays. Each type has its benefits; chemical sunscreens tend to be lightweight and easier to apply, whereas physical sunscreens are less likely to irritate sensitive skin and provide immediate protection.
Choosing the Right Sunblock for Your Skin Type
Selecting a sunblock depends on your skin type and lifestyle. For oily or combination skin, lightweight, non-comedogenic formulas that do not clog pores are ideal. Those with dry skin should look for sunblocks with added moisturising ingredients such as hyaluronic acid or glycerin. Sensitive skin requires hypoallergenic formulations free from fragrance, alcohol, or harsh chemicals to avoid irritation.
For those who spend extended periods outdoors, water-resistant sunblocks are important, as they remain effective even during sweating or swimming. Daily sunblocks for indoor use can be lighter, as the risk of heavy exposure is lower, but they still provide essential protection against incidental UV rays.
Key Ingredients to Look For
Modern sunblocks often include additional skincare benefits. Antioxidants such as vitamin C or E can neutralise free radicals caused by UV exposure, reducing oxidative stress on the skin. Niacinamide and peptides may also be included to strengthen the skin barrier and improve overall texture.
It is also important to consider the SPF level appropriate for your needs. SPF 30 is generally recommended for daily use, offering adequate protection for incidental sun exposure, while SPF 50 or higher is suitable for extended outdoor activities. Broad-spectrum protection ensures coverage against both UVA and UVB rays, maximising skin defence.
Application Tips for Effective Protection
Proper application is critical to achieve the full benefits of sunblock. Apply sunblock at least 15 to 20 minutes before going outdoors, allowing it to absorb and form a protective layer. Most adults require about a teaspoon of sunblock for the face and neck, and about one ounce (30ml) for the entire body. Reapplication is necessary every two hours, especially after swimming, sweating, or towel drying.
Layering sunblock with makeup and skincare products requires careful consideration. Many moisturisers and foundations now contain SPF, but these are not sufficient on their own. Sunblock should be applied as the final skincare step before makeup, ensuring maximum protection.
Conclusion
Daily sun protection is essential to maintain healthy, youthful, and resilient skin. Choosing the right sunblock involves understanding your skin type, considering lifestyle needs, and selecting products with broad-spectrum SPF and added skincare benefits. Proper application and regular reapplication enhance effectiveness, preventing long-term damage and supporting overall skin health. By making sunblock a non-negotiable part of your routine, you can enjoy the outdoors confidently while protecting your skin for years to come.
