What Causes Dry Skin?

Dry skin happens when your skin loses moisture faster than it can retain it. Common causes include cold or windy weather, hot showers that strip natural oils, harsh cleansers with strong surfactants, aging (oil production slows over time), and underlying skin conditions such as eczema. The result is that tight, flaky, uncomfortable feeling.

Best Ingredients for Dry Skin

  • Hyaluronic acid — a humectant that draws water into the skin for deep, lasting hydration.
  • Ceramides — replenish the skin's natural lipid barrier to lock moisture in.
  • Squalane — a lightweight oil that softens skin without feeling greasy.
  • Shea butter — a rich emollient that nourishes and seals in moisture.

Dry Skin Routine

Start with a gentle, non-foaming cleanser, then apply a hydrating serum to damp skin (humectants work best when there's water to grab onto). Follow with a rich moisturizer to seal everything in. Pro tip: running a humidifier at night adds moisture back into the air and helps skin stay hydrated while you sleep.

Frequently asked questions

How long does vitamin C take to fade dark spots?

Expect 6 to 12 weeks of daily use before judging results. Vitamin C works gradually by interfering with the enzyme that kicks off melanin production, so patience matters more than potency.

Can I use a vitamin C serum every day?

Yes. Unlike harsher brightening treatments, most people can use vitamin C daily without a difficult adjustment period. If your skin is sensitive, start every other morning for two weeks before going daily.

Do I need sunscreen when using vitamin C?

Yes, it is non-negotiable. Vitamin C can make skin slightly more sun sensitive, and unprotected sun will darken spots faster than any serum can fade them. Apply vitamin C in the morning under SPF 30 or higher.

What percentage of vitamin C works best for dark spots?

Research points to 10 to 20 percent as the sweet spot for fading discoloration. Beginners should start at the lower end, especially with L-ascorbic acid formulas.

Why did my vitamin C serum turn yellow or brown?

It oxidized. Vitamin C breaks down in light and air, and a color shift means it has lost strength. Choose dark glass bottles or airless pumps, store somewhere cool and dark, and replace discolored bottles.
