Brighter-looking skin, without hiding from the sun.

A note from Molly

“I was told to avoid the sun. I live in Hawai'i. So I made a vitamin C that doesn't ask that.”

What Tropical Glow does for sun-weathered skin

  • Softens the look of sun spots over time
  • Brightens uneven-looking tone
  • Adds a radiant, healthy-looking glow, never shiny
  • Feels silky, not stinging, on sun-warmed skin

You walk out the door feeling good in your skin.

Tired of other vitamin C serums?

  • They sting on sun-warmed skin
  • They break down in light and air
  • They add one more step to a long routine

Natural, powerful results

“Within 6 weeks I saw a noticeable difference in the dark spots on my entire face… This product is a must in my daily routine.”

– Michelle L.

Why Tropical Glow

  • THD Vitamin C doesn't sting and holds up in daylight.

    It's a sun-stable active, silky and oil-based, not harsh like common L-ascorbic acid. Clinical research shows that at 10%, THD Vitamin C supports collagen and reduces the look of age spots and uneven tone.*

  • The Sun Supporting Complex.

    The base of this serum is light, nourishing liliko'i, cucumber, and macadamia oils from plants that love the sun. They also give it its fresh scent, with no added fragrance.

  • Made in Hawai'i, where life is lived in the sun.

    Handmade in small batches in Kula, Maui. Our macadamia oil is Hawai'i-harvested, and our liliko'i oil is organic.

    Questions, answered

    Is it a sunscreen?

    No. Wear your SPF every day.

    Does it add sun sensitivity?

    No. Its active holds up in daylight.

    Any fragrance or essential oils?

    No added fragrance and no essential oils. The scent comes from the oils.

    Can I use it with other products?

    Yes. Use it alone, or with Jet Set. Two steps at most.

    Can I take it on a trip?

    Yes. It's one bottle that does the job of a longer routine.

    Can I use these if I spend a lot of time in the sun?

    Yes. Our four face formulas are made without sun-sensitizing actives, so you can use them morning and night. They aren't sunscreen, so keep wearing your SPF.

    How do I build a routine?

    Sun up: Tropical Glow, then Jet Set. Sun down: Island Refresh, then seal it in with Midnight Magic.

    Where are your products made?

    Everything is handcrafted in small batches in Kula, Maui.

    Do you offer free shipping?

    Yes. Orders over $100 ship free within the United States (before taxes and fees). Orders under $100 pay standard shipping rates.

    When will my order ship?

    Please allow 1–5 business days for us to process your order, not counting weekends and holidays. It can take a little longer during busy seasons.

    Do you ship outside the United States?
