The long-term effects on skin if you do not use sunscreen

Sunscreen: it’s a crucial part of your daily skincare routine, especially in sunny Singapore where the ultraviolet (UV) rays are unforgiving all year long. While it’s common to skip this step in the hurry of morning routines, there are long-term effects on your skin, from sunburn to an increased risk of skin cancer. 

Let’s explore these effects in detail and discuss how sunscreen can protect your skin.

Long-term effects

Without protection from the sun, UV rays can damage your skin cells. Some of this damage occurs over time and may only be felt or seen after prolonged, consistent exposure.

Sunburn

Repeated exposure to the sun without protection can lead to sunburn, which is not only painful in the short term but can also have long-lasting effects on your skin. Sunburn accelerates skin damage and can lead to peeling and redness, which indicate damage to the first layer of the skin. Over time, this damage can accumulate, leading to more serious skin conditions.

Premature ageing

One of the most noticeable effects of prolonged sun exposure without protection is premature ageing. This includes the appearance of fine lines, wrinkles, and a loss of moisture, which gives the skin a dry and leathery texture. This happens when UV rays break down collagen and elastin fibres in the skin, which are essential for maintaining its firmness and elasticity.

Weakened skin elasticity

Over time, the sun’s rays can weaken the skin’s elasticity by breaking down collagen and preventing new collagen from forming. This leads to sagging skin and a reduction in the youthful plumpness and resilience of the skin, making you look older than you are.

Eye damage

The delicate skin around the eyes is particularly vulnerable to UV damage, leading to crow’s feet, sagging eyelids, and even damage to the eyes themselves, such as cataracts. Wearing sunscreen and protective eyewear can help mitigate these risks.

Increased risk of skin cancer

Perhaps the most serious consequence of skipping sunscreen is the increased risk of skin cancer. UV radiation is a known carcinogen, and exposure without protection significantly increases the risk of developing skin cancers, including melanoma, which can be life-threatening if not detected early.

Pigmentation

Pigmentation, including dark spots and uneven skin tone, is another common consequence of not using sunscreen. UV exposure stimulates the production of melanin as the skin tries to protect itself from further damage. This can lead to hyperpigmentation, where patches of skin become darker than the surrounding area, making the skin appear blotchy and uneven.

Can sunscreen remove pigmentation?

Sunscreen does not remove existing pigmentation, but plays a crucial role in preventing new pigmentation from forming. For existing pigmentation, treatments such as topical creams, chemical peels, or laser therapy can be more effective, but daily sunscreen use is important as it prevents further skin damage.

Is a chemical or mineral sunscreen better for me?

Choosing between chemical and mineral sunscreens is a matter of personal preference and skin type. Chemical sunscreens contain organic compounds that absorb UV radiation and release it as heat. On the other hand, mineral sunscreens contain ingredients like zinc oxide or titanium dioxide, which physically block and reflect UV rays away from the skin. 

People with sensitive skin can consider using mineral sunscreens as they are less likely to cause irritation. However, chemical sunscreens can be more comfortable for daily wear due to their lighter texture. It’s important to choose a sunscreen that you feel comfortable wearing every day, as the best sunscreen is the one you will use consistently.

Incorporating sunscreen into your routine

Incorporating sunscreen into your daily routine doesn’t have to be a chore. Opt for a sunscreen that suits your skin type and texture preferences, whether that’s a lightweight fluid for oily skin, a moisturising cream for dry skin, or a tinted version for a bit more coverage. Apply it every morning as the last step in your skincare routine, and reapply every two hours if you’re spending extended periods outdoors. 

Remember: UV rays can penetrate clouds and windows, so it’s important to wear sunscreen even on cloudy days or when you are indoors.

If you spend long hours in front of a screen, consider a blue light sunscreen as blue light can cause pigmentation too. Our Spotless Blue Light Protection Sunscreen filters up to 90% of blue light and protects against UVA and UVB.
