As winter arrives and the days get shorter, we need to talk about sunscreen. I love skincare and dream of being a dermatologist, so I dug into why sunscreen matters all year. Let's break down why sunscreen is crucial, even when it's not sunny outside.
UV Rays 101:
UV rays are the sunlight that can harm our skin. UVB rays cause sunburn, but glass blocks most of them. Sneaky UVA rays, though, easily get through windows, leading to skin issues. Surprisingly, 75% of these aging rays can pass through windows. No matter the season, this emphasizes the critical importance of integrating sunscreen into our daily routine, regardless of the season.
Blue Light Blues:
Screens are all around us nowadays. Screens emit blue light, and being on them a lot can age our skin and cause other problems. Prolonged exposure to this light accelerates premature aging, stimulates melanin production, and may lead to pigmentation irregularities. Sunscreen acts like a shield against this digital harm, protecting us from the effects of constant screen time.
Mineral or Chemical Sunscreen:
In a recent shadowing experience with a local dermatologist, the mineral vs. chemical sunscreen debate came to light. Mineral formulations, enriched with zinc oxide and titanium oxide, create a physical barrier against UV and blue light without compromising pore integrity. Despite my positive experience with a chemical sunscreen (La Roche Posay Double Repair), considering the potential long-term health implications associated with chemical formulations, especially for those with sensitive skin, I might make a switch to mineral alternatives. It's always fascinating how evolving knowledge can reshape our skincare choices.
Sensitive Skin Alert:
Certain skincare products can heighten the skin's vulnerability to sun damage. Notably, the use of retinol, a common anti-aging ingredient, can thin the outer layer of the skin, increasing sun sensitivity and the risk of sunburn. So, it's essential to plan our skincare routines and always include sunscreen.
Sunscreen as a Skin Friend:
Forget the idea that sunscreen is thick and goopy. Modern sunscreens are infused with high-quality, skin-nourishing ingredients, offering hydration and protection in tandem. The evolution of sunscreen from a mere shield to a holistic skincare component underscores its significance in maintaining skin health.
In the skincare world, sunscreen isn't just for sunny days. Whether it's winter or we're indoors, sunscreen is like a best friend for our skin. Use it every day, not just as a precaution, but as a key part of keeping your skin strong, glowing, and healthy for the long run.
