If there’s one thing your dermatologist wants you to understand about your skin, it’s the importance of sun screen. Sunscreen is the best way to protect your skin when you’re out in the sun.

How It Works

Although different types of sunscreen contain slightly different ingredients, they all work in similar ways. Most sun creams and lotions use reflective particles such as titanium oxide or zinc oxide as well as organic molecules that can absorb light. These sunscreen ingredients are able to reflect or filter the light that reaches your skin. This means that less of the light penetrates the skin and reaches the deeper layers. Some light will still get through, but the sunscreen ingredients are particularly good at reflecting away or absorbing the most damaging wavelengths of UV light.

Why You Should Always Use Sun Screen

Reducing the amount of UV light that penetrates your skin is important because these wavelengths can damage your cells. Over time, this damage can cause the cells to change or grow abnormally. Many skin conditions, such as actinic keratoses, basal cell carcinomas, squamous cell carcinomas, and malignant melanoma can develop as a result of sun damage. Using sunscreen and other sun protection measures is the best way to prevent these kinds of problems. Although the importance of sun screen will depend on how sensitive your skin is to the sun, we should all use it regularly during the summer months.

However, while sun screen can play a key role in protecting your skin from the sun, there are limits to what it can do. It’s still important to take regular breaks from the sun to cool down, even when you’re using sunscreen. You should also try to avoid staying out in the sun between 11am and 3pm, as this is when it is strongest. It’s also vital to ensure that you’re using your sunscreen correctly. Choose a high SPF, apply plenty of lotion to your skin, and reapply it regularly throughout the day.
