Your day serum · 1 fl oz / 30mL
Liquid Gold.
A 10% THD Vitamin C serum for your day. It brightens the look of sun spots and uneven tone.
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.”
You walk out the door feeling good in your skin.
“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.
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 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.
Handmade in small batches in Kula, Maui. Our macadamia oil is Hawai'i-harvested, and our liliko'i oil is organic.
