Why Sun Care Is Essential for Preventing Skin Aging
Sun care is the most important skin management step that should be practiced throughout all four seasons. UV rays are the primary culprit that penetrates deep into the skin, destroying collagen and reducing elasticity. While many people only use sunscreen in the summer, UV rays that enter through windows on cloudy days or indoors can also affect your skin.
Understanding UV Types
- UVA: Penetrates deep into the skin, causing wrinkles and loss of elasticity.
- UVB: Causes sunburn on the skin's surface, leading to redness and hyperpigmentation.
The Core of Daily Sun Care
Making sunscreen a daily habit plays a decisive role in maintaining an even skin tone and preventing premature aging. K-beauty, in particular, emphasizes using sunscreen as the final step of your basic skincare routine to form a protective barrier. Sunscreen is not just for avoiding the sun; it acts as a shield that protects your skin from the external environment. Applying it thoroughly every morning before going out is an investment in your future skin health. Controlling the amount is important; it is recommended to apply an amount equivalent to two finger lengths evenly across the entire face.
