Physical Barriers – An Essential Layer of Protection
Even with the application of high-SPF sunscreen, your skin still needs an additional “shield”: physical barriers. According to dermatologist Dr. Nguyen Phuong Thao (Ho Chi Minh City Dermatology Hospital), common sunscreens can block only about 93-97% of UV rays when used in the correct quantity and applied evenly. However, UVA rays, which have the ability to penetrate deep into the skin and break down collagen, can still sneak through if there isn’t an auxiliary protective layer.
Always carry a light jacket, a wide-brimmed hat, and sunglasses when going outdoors. If you have to walk under the scorching sun, opt for thick, dark-colored fabrics with UV protection certification to minimize the risk of skin damage.
Additionally, don’t forget to bring a thick cloth mask or a 3-ply medical mask to protect the nose area – a spot that is prone to sun exposure and the formation of dark spots.
“Sunscreen is just one part of a comprehensive skin protection routine,” says Dr. Thao. “Physical barriers are the other crucial part that helps prevent ‘silent sunburn,’ which might not be immediately visible to the naked eye.”
Stay Hydrated – Moisturize from Within
Well-hydrated skin is healthy skin. Sun exposure can lead to water loss in the skin, resulting in dryness, flaking, or excessive oil production, which can cause acne. Therefore, after applying sunscreen and before heading out, remember to grab a bottle of water.
Experts recommend drinking at least 1.5-2 liters of water every day, spread throughout the day. In addition to plain water, you can include juices such as orange, pomegranate, or watermelon, as well as green tea – all of which help cool the body and are rich in antioxidants, aiding the skin’s recovery after exposure to UV rays.
Moreover, maintaining a healthy diet is crucial. Prioritize green vegetables and fresh fruits, and minimize the consumption of fried, spicy, and alcoholic beverages to keep your skin glowing from the inside out.
“Moisturizing the skin doesn’t only come from a jar of cream,” shares nutritionist Le Minh Hanh. “It starts with how you take care of your body every day.”
Reapply Sunscreen Properly – An Often-Overlooked Step
A common mistake is to apply sunscreen just once in the morning and then forget about it for the rest of the day. In reality, the effectiveness of sunscreen diminishes significantly after 2-3 hours, especially if you’re outdoors, sweating, or in contact with water.
To ensure continuous protection, develop the habit of carrying a small tube or spray-on sunscreen for easy reapplication during the day. If you’re wearing makeup, opt for powder or cushion sunscreen to avoid ruining your base.
Note that before reapplying, gently blot excess oil and sweat with a tissue to improve the adherence of the sunscreen without clogging pores.
“Reapplying sunscreen is not just a recommendation, but a necessity if you truly want to protect your skin,” emphasizes Dr. Thao.
Important: Choose the Right Sunscreen for Your Skin Type
Not all sunscreens are suitable for every skin type. Using the wrong product can lead to skin irritation, acne breakouts, or clogged pores.
- Oily/Acne-Prone Skin: Opt for gel-based, oil-free sunscreens that absorb quickly without leaving a greasy feel.
- Dry Skin: Choose sunscreens with moisturizing ingredients such as glycerin, hyaluronic acid, or ceramides.
- Sensitive Skin: Use physical sunscreens (containing zinc oxide or titanium dioxide), which are typically gentler and free of fragrances and alcohol.
Additionally, for daily use, an SPF of 30-50 is ideal. For outdoor activities, select SPF 50+ with PA+++ or higher to defend against both UVA and UVB rays.
In Conclusion
Proper sun protection goes beyond just applying sunscreen; it’s a holistic routine that nurtures your skin from the inside out. By following these three simple steps – physical protection, hydration, and regular sunscreen reapplication – you can effectively shield your skin from the harsh summer sun. Take care of your skin as you would your soul – with gentleness and persistence every day.
