Off the coast of Iceland, in tanks of pure glacial water, a tiny microalgae is quietly doing some of the most interesting work in skincare. It's called astaxanthin, and it has become one of the ingredients we reach for most often when we want to give skin real, visible support against everyday stress.

Where our Astaxanthin comes from
Astaxanthin is a natural pigment, the same one that gives wild salmon and certain algae their deep red color. Ours is cultivated from microalgae grown in Iceland's clean, cold waters, then drawn out using a supercritical CO2 extraction process powered by pure Icelandic glacial water and 100% renewable energy. No harsh solvents, no shortcuts. It's a slow, careful process, which feels fitting for an ingredient this potent.
Why we love it for skin
Astaxanthin is best known as an antioxidant, and by most measures, it's an unusually strong one. It's often described as having many times the antioxidant strength of vitamin C, CoQ10, and green tea, which is part of why such a small amount goes such a long way in a formula. In skincare, that antioxidant strength translates into a few real, feel-good benefits:
- Helps protect against everyday stress. Astaxanthin helps neutralize free radicals from environmental exposure, supporting skin's natural resilience.
- Supports visible hydration. It works alongside skin's own moisture barrier, helping skin feel plump and less prone to dryness.
- Softens the look of fine lines. With regular use, it can help support a smoother, more even-looking texture over time.
- Helps skin bounce back. Astaxanthin supports the appearance of elasticity, so skin looks and feels more resilient day to day.
A tiny amount of astaxanthin carries an outsized amount of antioxidant strength, which is exactly why so little of it can do so much.
How Astaxanthin Compares
| Antioxidant | Source | Known For |
| Astaxanthin | Microalgae (Icelandic glacial water) | Often described as many times stronger than vitamin C, weight for weight, so very little is needed in a formula |
| Vitamin C | Citrus fruits, Arctic berries | Brightening support, but can oxidize and lose potency once exposed to air and light |
| CoQ10 | Naturally occurring in skin cells | Supports skin's own antioxidant defenses, often used alongside other antioxidants |
Astaxanthin and Bakuchiol, together
We think astaxanthin is at its best in good company, which is why we paired it with bakuchiol, our plant-based retinol alternative, in the Moon Magic Bio-Retinol Serum. Bakuchiol helps visibly soften the look of fine lines and support skin's natural renewal overnight, while astaxanthin brings its antioxidant strength to help skin feel calm and supported against daily stress. Rosehip CO2 rounds things out with a dose of nourishment. Together, in just a few drops, they cover a lot of ground.
A quiet kind of skincare
There's nothing flashy about astaxanthin. It doesn't foam, it doesn't tingle, and you won't feel it working the way you might with a strong acid or a synthetic retinol. What you will notice, over time, is skin that feels steadier and looks a little more at ease with itself, which has always been the point of Icelandic skincare for us. Not chasing dramatic transformation, but supporting skin so it can do what it already knows how to do.
Why sourcing matters here
Not all astaxanthin is created equal, and where it comes from matters more than most people realize. Ours is grown, extracted, and formulated in Iceland, using renewable energy and glacial water rather than the synthetic astaxanthin found in many supplements and skincare products elsewhere. That distinction matters to us for the same reason our whole approach to skincare does. We would rather use less of something exceptional than more of something ordinary.
If you're curious to try it, Moon Magic is worth starting with in the evening, applied to clean skin before your moisturizer or face oil. Give it a few weeks of consistent use, since that's typically when the visible difference in texture and tone starts to show. Skin, like the Icelandic landscape it draws from, tends to reward patience.
The Research
Astaxanthin is one of the most researched carotenoid antioxidants in skin science. A systematic review of clinical studies found that astaxanthin supported several markers of skin health, including the look of fine lines, elasticity, and moisture (systematic review, Journal of Clinical Medicine).
