Why are UV Rays Detrimental to the skin?
The skin, being the largest organ in the human body, is constantly exposed to various environmental factors, including dirt, dust, pollution, and sun rays. Of these, ultraviolet (UV) radiation from sunlight is considered the primary cause of skin damage.
UV radiation is classified into three types: UVC, UVB, and UVA. UVA rays are mainly linked to skin aging and pigmentation. They penetrate deeply into the skin, producing free radicals that can indirectly damage DNA.
On the other hand, UVB rays cause sunburn and DNA strand breaks, leading to mutations such as pyrimidine dimers, which are linked to nonmelanoma skin cancers. As a result, avoiding excessive sun exposure is most effective for preventing skin cancer and photoaging.
How does Sunscreen reduce the Year-round threat of UVA and UVB Rays?
UV rays are present year-round, even on cloudy days and during colder months. While winter sun may seem less intense, UV radiation can still reach the skin and cause damage. Research suggests that approximately 80% of skin aging on the face is attributed to UV exposure. Therefore, consistent photoprotection is crucial year-round.
The three mechanisms by which sunscreens work are: absorbing, reflecting, or dispersing UV radiation. Based on their mechanism of action, sunscreens are classified as inorganic (mineral) and organic (chemical) sunscreens. Organic sunscreens, such as octisalate and avobenzone, absorb UV light and convert it into heat, which is then released from the skin.
Inorganic sunscreens, such as titanium dioxide and zinc oxide, work by reflecting UV light. However, they can leave a whitish residue and cause excessive shine, limiting their use in cosmetic formulations.
Most modern sunscreen formulations combine both chemical and mineral filters, offering the benefits of both types. Consistent application of sunscreen, along with other protective measures, helps to shield the skin from harmful UVA and UVB rays, preventing long-term skin damage and supporting overall skin health.
What makes a Sunscreen ideal and effective?
A sunscreen is considered effective if it protects against both UVA and UVB rays and helps reduce long-term skin damage and health risks from sun exposure. However, several important factors must be considered while determining a sunscreen as ideal. These factors include:
- Safe and non-toxic: It should not cause harm to the skin or body.
- Chemically stable and inert: It should not react with other ingredients or break down in sunlight.
- Non-irritating: It should not cause irritation or allergic reactions.
- Effective protection: It should block both UVB and UVA rays, providing full protection against sun damage.
- Water-resistant: It should remain on the skin for long hours even after sweating.
- Photostable: It should remain effective under the sun without losing its protective abilities.
- Good at protecting against free radicals: It should help protect the skin from harmful molecules caused by UV exposure.
- Low viscosity and non–odorous: It should spread easily on the skin without absorbing deeply into the skin and should not have a strong smell.
- Contaminant-free: It should be free from harmful impurities.
What is SPF and Why is it Important?
SPF, or Sun Protection Factor, is a measure of how well sunscreen protects your skin from UV rays, particularly UVB rays that cause sunburn. It helps to determine how much longer you can stay in the sun without burning compared to if you weren’t wearing sunscreen. For example, if you usually burn after 10 minutes in the sun, an SPF 30 sunscreen would protect you for 30 times longer, or 300 minutes, before burning.
SPF ratings are divided into categories: Low SPF (2–15), Medium SPF (15–30), High SPF (30–50) and Very High SPF (above 50). The level of SPF you need depends on factors like where you live, how much time you spend outside, and how easily your skin burns. People in sunny regions, especially near the equator, need higher SPF compared to those in colder climates.
It’s important to note that the actual protection may be less than the SPF number due to improper application or not reapplying often enough. It’s recommended to use sunscreen with SPF 30 or higher during sunny days or in summer. During fall and winter, when UV exposure is lower, you might not need sunscreen with high SPF as often.
How to use Sunscreen for Healthy and Glowing Skin?
Sunscreen is essential for protecting the skin from UV radiation, reducing the risk of sunburn, premature aging signs such as wrinkles, and skin cancer. It helps maintain an even skin tone, prevents hyperpigmentation, and prevents freckles and age spots. Regular use of sunscreen, especially during outdoor activities, is crucial for long-term skin protection and youthfulness.
Here’s how you can achieve beautiful and glowing skin with daily use of sunscreen:
- Opt a broad-spectrum sunscreen with SPF 30 or higher for daily use, and SPF 50+ for extended outdoor exposure.
- Apply a generous amount of sunscreen for your face and body, ensuring you cover often-missed areas like your ears, neck, and hands.
- Apply sunscreen at least 15 minutes before going outside to allow proper absorption.
- Reapply sunscreen every 2 hours, or more often if swimming, sweating, or wiping your face.
- Use sunscreen even on cloudy or rainy days.
- Layer sunscreen last in your skincare routine, after moisturizers and serums, for the best protection.
- Maintain consistent use of sunscreen to prevent sunburn, aging, skin cancer, and dark spots, promoting healthy, glowing skin.
- Use sunscreen along with other skin protection measures such as staying in the shade, wearing protective clothing, and using sunglasses for additional sun protection.
By using sunscreen consistently and correctly, you’ll not only prevent your skin from damage, but you’ll also maintain healthy, glowing, and youthful skin over time!
How to select a Sunscreen suitable for your skin?
When selecting a sunscreen suitable for your skin, it’s important to consider your skin type first.
If you have oily skin, look for an oil-free or matte finish sunscreen to avoid clogging pores and excess shine, and opt for gel-based or water-based formulas. For dry skin, choose a sunscreen with added moisturizers like glycerin or hyaluronic acid to keep your skin hydrated. If you have sensitive skin, go for mineral sunscreens containing zinc oxide or titanium dioxide, as these are less likely to irritate. For combination skin, select a non-comedogenic sunscreen that provides balanced hydration without causing breakouts or excess oil.
In addition to skin type, it’s crucial to pick a broad-spectrum sunscreen, with added anti-aging properties or antioxidants to provide additional skin benefits. If you are prone to allergies or irritation, opt for sunscreens that are free from harmful ingredients like fragrances, parabens, phthalates, and Oxybenzone.
Lastly, sunscreens come in different formulations such as lotions, sprays, gels, and sticks. Choose the one that suits your preferences and ensures easy, consistent application. By considering your skin type, SPF needs, and any extra skincare goals, you can select the perfect sunscreen to protect and care for your skin.
