5 principles for using sunscreen in summer to ensure optimal skin protection.

When the weather turns hot, sunscreen becomes an indispensable product in your daily skincare routine.

Pay attention to the expiration date; do not use products that have been opened for too long.

Sunscreen also has a much shorter shelf life than other skincare products. After opening, the product's quality can be affected by light, temperature, and air. Therefore, even if the expiration date printed on the packaging is still valid, products that have been opened for more than 6–8 months should be replaced. Continuing to use sunscreen that has changed texture or is past its expiration date will not only reduce its sun protection effectiveness but may also cause skin irritation.

Choose a texture that suits your skin type.

The effectiveness of sunscreen largely depends on choosing the right type for your skin type. For oily skin, lightweight textures like gel or lotion will help prevent clogged pores. Conversely, dry skin should prioritize moisturizing products to avoid tightness and irritation. For sensitive skin, a simple ingredient list, avoiding fragrances and irritating substances, is crucial. Choosing the right product and using it daily is essential for it to be truly effective.

Prioritize products that offer a slight brightening effect.

To simplify your summer makeup routine, a tone-up sunscreen is a popular choice. This product helps skin look brighter and more even-toned without needing additional foundation. It also makes reapplication throughout the day easier, eliminating the need to remove previous makeup. However, it's important to choose a shade that closely matches your natural skin tone to avoid an unbalanced look.

Combine with vitamin C to enhance skin protection.

Vitamin C doesn't make skin more susceptible to sun damage as many people believe; on the contrary, it helps strengthen the skin's ability to fight against UV rays. When used in the morning before sunscreen, this active ingredient helps neutralize free radicals and improve dullness and brown spots. The combination of vitamin C and sunscreen creates a more comprehensive protective layer, helping to reduce the risk of skin damage and premature aging.

Cleanse your skin thoroughly at the end of the day.

Even if you only use sunscreen, removing makeup is still a necessary step to ensure your skin is completely clean. If not removed, the cream, dirt, and excess oil will accumulate in the pores, easily causing acne and making the skin rough. Makeup removal helps to keep the skin's surface clear, allowing subsequent skincare steps to be more effective. This is a crucial step in maintaining healthy skin throughout the summer.
