  • What Customers Are Saying

    ★★★★★
    "Just bought a second bottle as this really does make my face look brighter and more youthful with consistent use."

    — Ruth Berg



  • Freshness Matters

    Pure L-ascorbic acid is highly effective—but notoriously unstable. PURESHINE METHOD is made in small batches to help ensure the serum you receive is fresh.

Why Vitamin C Matters After 40

As skin matures, collagen production naturally declines, while years of exposure to UV radiation and environmental stress can become more visible. L-ascorbic acid is one of skincare's most extensively studied antioxidants, helping defend against free radicals while supporting collagen production and a more even, radiant-looking complexion.

Because effective skincare starts with understanding the science behind it.

Created by a Chemistry Educator with a Background in Toxicology

GlowLab 5:16 was created from a simple belief: skincare should come with an explanation—not just a promise. Founder Kim Stanage approaches skincare the way she approaches science—by asking not only what works, but why it works.
