Around 3 p.m. on a lazy afternoon, I was enjoying my own fashion show in front of the mirror, trying on newly delivered winter knits and coats one by one. However, unlike the vibrant colors of my clothes, my reflection in the mirror revealed a dull, worn-out complexion from the heater. The difference in indoor and outdoor temperatures and UV rays in winter are major contributors to accelerated aging, so I was reminded of the importance of skin care. A closer look at the ingredients in the Liviheal sunscreen revealed a striking skin regeneration mechanism that goes beyond simple UV protection. While sunscreens typically leave a white cast or dryness depending on the ingredient content, Liviheal sunscreen contains human adipose cell culture extract and exosome ingredients, creating a moisturizing cream-like texture that replenishes the skin barrier. Furthermore, the exosome technology within Liviheal sunscreen enhances the penetration of the active ingredients, maintaining a subtle, long-lasting glow even on my skin, which tends to become dull in the afternoon. Sunscreens are often reluctant to be layered in the winter due to their greasy feel, but this product balances oiliness to invigorate a stagnant skincare routine. Ultimately, the ability to provide both UV protection and antioxidant care with just one product—a truly logical choice, even from an ingredient analyst's perspective. Looking at myself in the mirror today, I realized once again that a sunscreen with solid base ingredients is essential for maintaining a vibrant complexion in the dry winter air.
