While certain serums, moisturizers, and injectables can help repair skin and improve visible signs of aging, sunscreen remains the foundation of a good anti-aging routine. It is your first line of defense against ultraviolet (UV) radiation, which is a major contributor to aging, including premature wrinkles, sagging, and sunspots.

In a tropical country like Singapore, protecting your skin from daily UV exposure is important to keeping it radiant and youthful. And if you’re investing in non-surgical aesthetic treatments such as botulinum toxin, facial fillers, or Ultherapy in Singapore, regular and proper sunscreen use is crucial to maintaining your results.

UV radiation and your skin 

Studies suggest that 90% of visible skin aging is caused by the cumulative effects of the sun’s UV radiation. This phenomenon is referred to as photoaging, which means premature aging of the skin due to long-term exposure to UV radiation, mainly from the sun. It is characterized by: 

• Fine lines and wrinkles

• Age spots (also called sunspots or liver spots)

• Pigmentation

• Rough or leathery skin texture

UV rays damage the skin by:

• Breaking down collagen and elastin – UVA rays can penetrate deep into the skin and damage both collagen and elastin fibers, which are essential for maintaining skin firmness and elasticity.

• Causing premature aging – the breakdown of essential skin proteins contributes to the formation of wrinkles, fine lines, and sagging skin. This can also worsen the appearance of existing signs of aging.

• Damaging skin cells –UV rays can damage the DNA in skin cells, potentially causing mutations that lead to the development of skin cancer. UVB rays, furthermore, are the main cause of sunburn, which is a sign of skin damage. 

• Causing hyperpigmentation – exposure to UV rays can trigger melanocytes or pigment-producing cells to produce more melanin, resulting in age spots and uneven skin tone. It can also darken or worsen existing hyperpigmentation on your skin.

How does sunscreen compare to other anti-aging products?

Quality broad-spectrum sunscreens protect the skin from the effect of UV rays, as well as help slow down visible signs of aging. Here’s how it compares to some of the most common anti-aging ingredients.

If you’re going to have just one anti-aging product…

Make that sunscreen. In Singapore, where the average UV index is between 6 and 9 and can reach extreme levels (11+) during certain times of the day and year, protecting your skin daily is a must. Here’s how to choose sunscreen in Singapore or some things to look for when buying an SPF.

• Broad-spectrum (can offer both UVA and UVB protection)

• SPF of at least 30 or higher

• Lightweight and non-greasy (ideal for hot and humid weather)

• Non-comedogenic (won’t clog pores)

• Expiration dates (if you have a sunscreen that’s past its expiration date, toss it)

At Dr. Sylvia Skin Care, we have Sunshield SPF 45, which is a lightweight and non-greasy formula designed to provide broad-spectrum protection. It also contains skin-loving ingredients to nourish, hydrate, soothe, and calm the skin. This formula is also free from fragrances and dyes, making it suitable for those with sensitive skin.

We also have Sheer Defense Tinted SPF 46, which is a universally tinted sunscreen that provides broad-spectrum coverage from UVA, UVB, and infrared radiation. This fast-absorbing formula features a high level of antioxidants and contains niacinamide to reduce redness and blotchiness. 

Take note: The best anti-aging sunscreen is the one you’ll use consistently. Regular and consistent application is essential for effective sun protection and for preventing premature or visible signs of aging. 

Common sunscreen mistakes to avoid

To get sunscreen’s full protection, it should be applied the right way. Here are the most common sunscreen mistakes and how to avoid them. 

• Using too little – for adequate face and neck protection, you need roughly a half-teaspoon of sunscreen. For full body protection, you need about an ounce or a shot full of glass.

• Skipping sunscreen on cloudy days and indoors – UVA rays can penetrate clouds and windows, so it is important to wear sunscreen even on cloudy days or indoors near windows.

• Relying solely on sunscreen – no sunscreen can block 100% of the sun’s UV rays. Make sure that apart from wearing sunscreen, you should also seek shade, limit sun exposure, and wear sun protective clothing, a wide-brimmed hat, and sunglasses with UV protection.

• Using an old formula – always check the sunscreen’s expiration date. If there is none, discard the bottle three years after purchase.   

• Forgetting certain areas – these include the ears, scalp (hairline part), lips, eyelids, neck, tops of the feet, and hands. 

Why sunscreen is particularly important in Singapore

Sunscreen in Singapore should not just be a holiday or beach-day product; it should be your 365-day skincare must-have. Here’s why:

• Tropical climate with warm temperatures and high humidity 

• Consistently high UV index rating

• Proximity to the equator means it experiences high levels of UV radiation all year round 

• Indoor lighting also emits blue light, which can contribute to premature aging

• Certain skin concerns are more common in Asian skin (e.g. melasma, hyperpigmentation)

Make broad-spectrum sunscreen in Singapore your top anti-aging product. And if you’re looking to elevate your skincare routine or maintain your glow for years to come, invest in the right products.
