5 Reasons Women Over 50 Are Trying This Japanese Skin Habit (It's Not a Cream)

It's a daily softgel of astaxanthin, the red antioxidant made by microalgae. Here's what it does, what the research shows, and how to take it.

If you just watched our video, you already heard the short version: in Japan, plenty of women don't think of skincare as something that only comes in a jar. They also take it.

The ingredient is astaxanthin (say asta-ZAN-thin). It's a natural red pigment made by a freshwater microalga, and it's the same pigment that gives wild salmon their pink color. In Japan it has been a popular "beauty from within" supplement for years. In the US, most women have never heard of it.

Here are five reasons that's starting to change, and what to look for if you want to try it.

Creams work on the surface. Astaxanthin works from within.

Serums and night creams go on the top layer of your skin, and that's where most of them stay. But a lot of what makes skin look older happens underneath. Years of sun and everyday oxidative stress slowly wear down the moisture and bounce your skin had in your 30s.

Astaxanthin is taken by mouth, with a meal. It's absorbed along with the fats in your food and carried through your body, so it supports your skin from the inside, where creams can't reach.*

That's the idea behind the habit in our video. You don't have to throw out your moisturizer. You're adding the part a jar can't do.

It's one of nature's most unusual antioxidants.

Most antioxidants protect either the watery parts of a cell or the fatty parts. Astaxanthin's long, rod-shaped molecule can span the entire width of the cell membrane, so it can intercept free radicals inside the membrane and along both of its surfaces.1

It also does this without turning into a pro-oxidant itself, which some antioxidants can do.1 In plain terms, it's built to help defend your cells, including your skin cells, against the everyday oxidative stress that adds up with age.*

It's been tested on women's skin, against a placebo.

AstaxanthinNo significant change: skin held steady

In a 16-week study in Japan, 65 healthy women took 6 mg or 12 mg of astaxanthin a day, or a placebo, from August to December, when UV and dry air are hard on skin. In the placebo group, wrinkle measurements and skin moisture got significantly worse. In the astaxanthin groups, they didn't significantly change.2

A 2021 analysis that pooled the controlled human trials found that taking astaxanthin significantly improved skin moisture and elasticity.3 And in a separate 10-week study, people taking astaxanthin lost less skin moisture after UV exposure than people taking a placebo.4

These were small studies, and results vary from person to person. But the pattern is consistent: the benefits come from daily use over weeks, not overnight.*

It comes from microalgae, not a lab.

In nature, astaxanthin is made by Haematococcus pluvialis, a freshwater microalga that turns deep red when it's exposed to harsh sunlight. That red pigment is astaxanthin, the alga's own protection. Salmon, shrimp and flamingos get their pink color from eating it, up the food chain.

Astaxanthin can also be made synthetically, and most synthetic astaxanthin ends up in fish feed. Most of the human skin research has used astaxanthin from microalgae.3

Innareve For Her uses only natural astaxanthin from Haematococcus pluvialis microalgae. Never synthetic, never petroleum-derived.

12 mg, already in oil, so your body can absorb it.

Astaxanthin is fat-soluble: your body absorbs it together with fat, not water. That's why the form matters. An oil-based softgel, taken with a meal, gives it the fat it needs.

Each Innareve For Her softgel contains 12 mg of astaxanthin, the higher of the two daily doses tested in the 16-week study,2 suspended in MCT oil, a light fat that's easy for your body to absorb. Take one or two a day with a meal. That's the whole routine.

What's in each softgel

  • Astaxanthin, 12 mg, from Haematococcus pluvialis microalgae
  • Other ingredients: MCT oil, bovine gelatin (BSE-free), vegetable glycerin, purified water, rosemary extract
  • How to take it: 1 to 2 softgels a day with a meal, or as directed by your healthcare professional
  • Each pouch: 30 softgels (a 15- to 30-day supply)

Common questions

How long until I notice a difference?

Astaxanthin works gradually. In the studies, changes in skin moisture and elasticity were measured after 9 to 16 weeks of daily use, so plan on taking it every day for at least two to three months. Results vary.

How do I take it?

One or two softgels a day with a meal, or as directed by your healthcare professional. Taking it with food helps your body absorb it.

Can I keep using my skincare?

Yes. Innareve For Her doesn't replace sunscreen or your moisturizer. It works alongside them, from the inside.

Is it right for me?

If you're pregnant, nursing, taking medication, or have a medical condition, check with your healthcare professional before taking it.

What if it's not for me?

Your first order is covered by our 90-day money-back guarantee, even if you've opened the pouch. Email support@innareve.com within 90 days of delivery. See our refund policy for details.
