When Should I Apply Specific Products?
When it comes to skincare, timing truly matters. The products we use and when we use them can dramatically impact their effectiveness—and in some cases, even our safety.
Everyone Should Wear Sunscreen—Yes, Even Indoors
Whether you're outside under direct sun or inside working under artificial lights, daily sunscreen use is essential. UV rays can still reach your skin through windows, and blue light exposure—like the kind from fluorescent lighting and computer screens—can also contribute to premature aging and skin damage.
This is especially relevant for night-shift workers like nurses or those in healthcare. Even though you might not see the sun during your shift, long hours under bright indoor lighting can still affect your skin. In these cases, applying a broad-spectrum SPF during work hours can provide a layer of defense against blue light–induced oxidative stress.
Reserve Your Acids for Night Time
Exfoliating acids such as lactic acid, glycolic acid, and Retin-A (Tretinoin) are powerful tools for improving skin tone, texture, and overall appearance. But there's a catch: they increase your skin's sensitivity to sunlight.
Using them during the day can leave your skin vulnerable to irritation, redness, and even hyperpigmentation. That’s why these ingredients are best reserved for your evening routine, where they can work overnight without risking sun exposure.
Vitamin C: A Daytime Hero
On the flip side, vitamin C serum shines brightest during the day. This potent antioxidant helps neutralize free radicals caused by UV rays, air pollution, and other environmental aggressors. Think of it as your skin's daily armour—protecting your collagen, brightening your complexion, and reducing signs of premature aging.
Pair your vitamin C serum with a daily sunscreen to create a powerful daytime protection duo.
Skincare isn’t just about what you use—it’s also about when you use it. Protect during the day with SPF and vitamin C, and repair at night with acids and retinoids. And remember: even if you’re indoors or working a night shift, your skin still deserves care and protection.Your skin is with you for life—treat it like your favorite outfit, and wear it well.
