When I was younger, sunscreen application only came to mind during beach holidays or summer vacations. Since studying and broadening my knowledge, plenty has changed! Sunscreen is simply a year-round non-negotiable. Even if it is a cloudy day and even if you stay inside the entire day, your skin is still exposed to UV radiation. It is not an accessory but rather an absolute necessity in any weather conditions.

UV radiation is known to cause premature aging, pigmentation and it can increase your risk for skin cancers.

Understanding UV Radiation
The sun emits two main types of ultraviolet (UV) rays that affect the skin namely UVA and UVB.

1. UVA rays penetrate deep into the skin and are primarily responsible for aging and long-term skin damage.
2. UVB rays affect the outer layer of the skin, causing sunburns and playing a significant role in developing skin cancer.

I like to remember that UVA contributes to ageing and UVB contributes to burning. Both of these rays are present every single day.

A shocking up to 90% of ageing is caused by the sun and exposure to UV rays.

Reasons to apply sunscreen every day:
Protection against premature ageing: UV exposure is one of the main reasons for premature ageing, known as fine lines, wrinkles, and age spots.

Prevention and treatment of hyperpigmentation: Sunscreen helps manage melasma, post-inflammatory hyperpigmentation, and uneven skin tone.

Reduced skin cancer risk: Regular use and reapplication of sunscreen significantly lowers the risk of various skin cancers, including melanoma.

Supporting overall skin health: Sunscreen acts as a shield for your skin from daily UV damage. It keeps the skin resilient and reduces inflammation.

Why you should wear sunscreen when staying indoors

• UV rays penetrate windows: UVA rays can pass through glass thus causing skin damage inside your home or office.
• Blue light exposure: Phones, tablets, and computers emit blue light, which may contribute to premature aging and hyperpigmentation.
• Indoor lighting risks: Some indoor lights can emit low levels of UV radiation that can affect your skin over time.

Choosing the Right Sunscreen
With an overload of options on the market it is important to choose the correct one as not all sunscreens are equal. Look for a broad-spectrum sunscreen, which protects against both UVA and UVB rays. Aim for at least SPF 30 for daily wear and higher if you’re outdoors for extended periods.

According to skin type:

1. For dry skin: Opt for hydrating formulas with ingredients like hyaluronic acid or glycerin.
2. For oily/acne-prone skin: Use non-comedogenic, lightweight, matte-finish sunscreens.
3. For sensitive skin: Choose mineral-based sunscreens with zinc oxide or titanium dioxide.
4. For pigmentation: Use a sunscreen with added protection against visible light and infrared rays – like a tinted sunscreen. Look for ingredients like niacinamide, vitamin C, or iron oxides to help fade dark spots and prevent further discoloration.

How to Apply Sunscreen Correctly

• Apply as the last step in your morning skincare routine.
• Use about 2 finger lengths worth of sunscreen for the face and an additional one for the neck.
• Don’t forget your ears, neck, and hands.
• Reapply every two hours, or immediately after sweating or swimming.

In conclusion, incorporating sunscreen into your daily routine is an overlooked powerful step in protecting your skin. It simply isn’t just about avoiding sunburn but maintaining long-term skin health. Daily sunscreen use isn’t just for sunny days outside—it’s a smart, everyday skin habit.

Remember nothing looks better in your 40’s than sunscreen in your 20’s
