A Complete Guide to UV Protection and Sunscreens by Dr. Ivana Stanković
Understanding UV Radiation
UV radiation from the sun comes in three forms: UVA, UVB, and UVC. UVA rays penetrate the skin more deeply, leading to aging and long-term damage, while UVB rays are primarily responsible for sunburn. UVC rays are absorbed by the Earth's atmosphere and do not reach its surface. Dr. Ivana Stanković advises choosing broad-spectrum sunscreens that protect against both UVA and UVB rays for comprehensive skin care.
The Importance of Sunscreen
Sunscreens act as a shield against harmful UV rays. There are two main types of filters: chemical filters that absorb UV rays and physical filters that reflect sunlight away from the skin. Dr. Ivana Stanković recommends using sunscreens with at least SPF 50 daily and reapplying every two hours during continuous exposure.
Tips for Effective UV Protection
-
Don't Skimp on Sunscreen: Many people don't use enough sunscreen. A good rule of thumb is to use about one ounce (enough to fill a shot glass) on all exposed areas of the body.
-
Wear Protective Clothing: Wide-brimmed hats, long-sleeved shirts, and sunglasses with UV protection can provide additional defense against UV rays.
-
Seek Shade: Sun rays are strongest between 10 a.m. and 4 p.m. During these hours, it's best to avoid direct sunlight.
-
Don't Forget Cloudy Days: UV rays can penetrate clouds, so sunscreen is necessary even when the sky is overcast.
-
Beware of Reflections: Water, sand, and snow can reflect and amplify UV rays, increasing your exposure even when you're under an umbrella or in the shade.
The Role of Antioxidants in UV Protection
In addition to filters, antioxidants play a crucial role in protecting the skin from UV-induced damage. Ingredients like vitamin C, vitamin E, and ferulic acid can neutralize free radicals generated by UV exposure, offering additional protection.
UV Protection and Sunscreens - Everything You Need to Know
Ultraviolet (UV) radiation is invisible to the human eye but can have both positive and negative effects on our health. On one hand, it's responsible for the production of vitamin D3, essential for the proper functioning of the body. On the other hand, it can lead to premature skin aging and even cancer development.
UV Filters - Types and Function
There are two main types of UV filters:
- Chemical Filters: Absorb UV radiation and convert it into heat energy.
- Mineral Filters: Reflect UV radiation away from the skin's surface.
Chemical filters are usually more transparent and easier to apply on the skin, while mineral filters are more stable and less prone to allergies.
When Choosing a Sunscreen, Pay Attention to:
- SPF (Sun Protection Factor): The higher the SPF, the greater the protection against UVB radiation.
- Broad-Spectrum Protection: The sunscreen should protect against both UVB and UVA radiation.
- Water Resistance: If you plan to swim or sweat, choose a water-resistant sunscreen.
UV Protection - Tips
- Use Sunscreen with SPF 30 or Higher Every Day: Even on cloudy days.
- Apply Sunscreen Generously and Evenly: On all exposed body parts, at least 15 minutes before going outside.
- Reapply Every 2 Hours: And always after swimming.
- Wear Sunglasses with UV Protection: To protect your eyes from harmful radiation.
- Avoid Excessive Tanning: Especially between 11 a.m. and 3 p.m. when the sun is strongest.
UV protection is crucial for maintaining healthy and beautiful skin. Using sunscreens is one of the simplest and most effective ways to protect yourself from the sun's harmful effects.
Dr. Ivana Stanković, a renowned medical doctor and dermatologist-venereologist, a member of the Polish Dermatological Society (PTD), offers dermatoscopic examinations in her clinic, which she recommends to every patient twice a year to monitor any moles that may be dangerous.
Remember, using sunscreen is an investment in both beauty and health. Take care of yourself and protect yourself from the sun!
