Why You Should Apply Indoor Sunscreen, Even If It's a Dessert

Many people tend to skip sunscreen on days when they stay indoors. However, if you want to prevent skin aging, you must apply sunscreen even indoors. This is because UVA, which has a long wavelength, passes straight through indoor windows and glass and penetrates deep into the skin. While UVA does not cause immediate burns, it is the main culprit behind wrinkles, loss of elasticity, and age spots by destroying collagen. Additionally, even the faint light emitted from indoor lighting or electronic devices can irritate the skin if exposed for a long time. Therefore, to protect your precious skin, you must make it a habit to apply sunscreen as the final step of your morning skincare routine, even indoors.
