What is it: Astaxanthin

February 12, 2012 Reviewed by admin 27 Comments

You may have heard mentions of the "world's most powerful antioxidant"...but probably not in reference to astaxanthin, a breakthrough ingredient that has kept a relatively low profile in spite of its momentous promises. In the animal kingdom, this dark red carotenoid pigment is present in the skin and tissues of a variety of sea creatures, including salmon, trout, and lobster, as well as certain birds, such as flamingo and quail. But its effects on humans have only recently become known, and its availability in cosmetics is rather scarce.

Even though I've noticed trace amounts in products such as Perricone MD's Firming Neck Therapy, I have only seen astaxanthin prominently marketed in a serum by H. Maloha and a cream by Kenneth Mark MD (to be reviewed soon). More prevalent in nutritional supplements than skincare, astaxanthin is believed to produce a number of actions in the body, providing both antioxidant and anti-inflammatory protection. Once you learn what this unassuming antioxidant is capable of, you might wonder where it's been all your life.

Where does it come from. In commercial products, astaxanthin is most often extracted from the marine microalgae haematococcus pluvialis, the richest known source for this natural pigment. The primary use of synthetic astaxanthin today is as an animal feed additive to impart coloration to farmed fish, such as salmon and red sea bream. A number of in-vitro experiments, in-vivo pre-clinical studies, and early-stage trials performed during the past five years have indicated the possibility that astaxanthin behaves as a curing agent against various health conditions. Because of its superb antioxidant potential, the demand for astaxanthin is expected to grow significantly in the multi-billion dollar nutraceutical market in the near term.

How do antioxidants work. During normal cellular metabolism, environmental stressors such as UV light, smoke, pollution, and even oxygen create damaging by-products, or free radicals, that make the skin appear older than it actually is. A closer examination reveals that these factors cause reactive oxygen species (ROS) to build up in skin and inflict damage at a cellular level. Effectively shielding the skin and slowing down premature signs of aging caused by the environment, antioxidants scavenge free radicals and bind to them before they can do damage.

What's so great about astaxanthin. When ROS get embedded in the skin's surface, they cause lipid peroxidation of the top layer (stratum corneum), which reduces the natural barrier function. An excess of ROS can break down the collagen matrix, leading to wrinkle formation and loss of elasticity. In penetrating the skin and protecting each dermal layer from ROS-related damage, astaxanthin helps reduce moisture loss, promote smoothness, and elicit cellular renewal. Analyses have shown that astaxanthin is also an efficient absorber of specific ultraviolet sunlight rays that may contribute to skin aging and cancer. These properties explain why astaxanthin is included in topical skin care formulations.

Why it does a body good. When there is an overproduction of ROS, the resulting oxidative stress has detrimental effects that can lead to various diseases. In numerous studies, astaxanthin has proven to alleviate medical conditions by enhancing immune response and decreasing DNA damage. Astaxanthin's free radical-scavenging activity protects lipids from peroxidation and reduces oxidative damage of LDL-cholesterol, thus reducing arterial plaque formation. With a unique molecular structure that enables it to cross the blood-brain barrier in mammals, astaxanthin can extend its powerful antioxidant protection to the central nervous system, which is highly susceptible to oxidative damage by ROS because of its richness in unsaturated fatty acids.

How it compares to other antioxidants. When tested against common antioxidants, astaxanthin has demonstrated exceptional performance in combatting singlet oxygen, one of the strongest ROS, which directly damages biological lipids, proteins, and DNA. Despite some variance in numbers, there have been all sorts of claims about the superiority of astaxanthin. A clinical research study by Dr. Debasis Bagchi at Creighton University demonstrated that astaxanthin can eliminate free radicals 6,000 times more effectively than vitamin C, 800 times more than CoQ10, 550 times more than vitamin E and green tea, 75 times more than Alpha Lipoic Acid, and 20 times more than beta-carotene.

Where to find it. These findings are supported by a 2007 study sponsored by Fuji Chemical Industry, a 60-year-old Japanese pharmaceutical company and the leading manufacturer of natural astaxanthin in nutritional supplements. Asaxanthin is becoming an increasingly popular therapeutic addition to the diet to treat immune, inflammatory, and neurodegenerative disorders. Fuji's AstaReal brand of astaxanthin is approved for nutritional use in the U.S., Europe, Japan, and other markets worldwide. The company is conducting further studies on the effects of astaxanthin in cardiovascular problems, weight management, and diabetes.

At around $325 per pound, astaxanthin is a rather expensive cosmetic ingredient. Currently, it seems far more affordable and widespread in dietary supplements than in skincare products.

    I think you have to take the recommendations of Youtubers with caution. I work in an industry that uses 'influencers' on YT, they are remunerated (as well as getting the products for free) but the vast majority you would not know that from watching the videos. It's a very lucrative business.

    That's not a comment on the efficacy of Astaxanthin (I've just taking a supp myself), just a response to a comment I saw mentioning the glowing reviews from YTers.

    I've been using The Superblend Pressed Serum Concentrate from Maya Chia beauty, and it has astaxanthin very high on the ingredient list. It's basically a balm that promises a host of anti-aging benefits, as well as a brighter, more even toned complexion. As much as I love it for a good dose of moisture (it is made predominantly from oils....babassu and chia seed being the first two ingredients, astaxanathin the third, followed by a number of other oils), I've seen no improvement in even my light pigmentation problems and no improvement in any other area either, other than the moisture I mentioned above. Seems every YouTuber out there loves it, but for $105/1.7 oz, I am FAR from sold, although a jar does last a long time. I'm still curious enough to try other skincare containing astaxanthin, but that particular "pressed serum concentrate" wasn't the gem I'd hoped for.

    I have been using esente skincare products for several years and love the fact that they provide really good anti-aging effects. My absolute favorite product (and I believe one of their best sellers) is Red Volcanic Seaweed Complex. What an amazing product this is. It has a very high concentration of Astaxanthin and other excellent botanical ingredients. My friend recommended this product to me years ago as I was suffering from inflammation problems and severe irritation about a series of laser treatments. The Red Volcanic Seaweed Complex was a true blessing and a product I cannot live without,

    I picked this up to take care of a couple of neuro disorders ( until I see a doctor) and potential immune builder. By chance I was in the vitamin store, stumbled upon it and talked to the sales clerk about and soon googled it before taking the 10mg supplement daily. and I have to tell you it is effective for what I would call ultra sensitive skin and ringing in the ears. In the week that I have been taking it I have been asked if I've been sitting in the sun as my face has somewhat changed to a tanned orange color. This particular brand says " extracted from haematococcus pluvialis ". I have no clue if it does anything for wrinkles too soon to tell.

    DHC's cream doesn't list astaxanthin in the ingredients, but does list oil from a fish called orange roughy. I suspect this would be the source of astaxanthin. Unfortunately, this fish is very depleted and almost an endangered species. It is also a species that typically has high levels of mercury.

    I have been researching Astaxanthin use for the skin a day came across a product sold by DHC. It is Astaxanthin Collagen All-in-One Gel, #22584. I have not tried it yet but you can get a free sample mailed to you.

    I've been buying vitamin c serum for a long time and had no problem with it until they added Astaxanthin to it. I had to stop taking the serum because it caused my face to be sore and caused my face to have rough patches all over. I had to wash it off right away.

    I can vouch for the Skin Actives site. I have been buying from them for several years now. I am taking purium BIO supplements which contains AstaREAL. Time will tell!

    Hi I came here looking for info on this because I found a brand called OZ on Amazon that claims to use it, but their prices are not high at all and after reading the cost of the supplement I'm wondering if its actually in them! So I wanted to drop off the url so you could check it out!

    Thanks A Bunch I love your work!

    Astaxanthin is in some products in the First Aid Beauty line I bought at Sephora, specifically the Dual Repair Face Cream and the serum that goes with it (I think it's called Dual Repair Face Serum. It's probably in their Dual Repair eye cream too.

    I just found astaxanthin in a wonderful "Hand and Body Moisture Therapy" lotion from Derma E. The lotion is wonderful, refreshing and absorbs quickly. It is also fragrance free. Very reasonably priced on

    I started taking Swanson ultra Astaxanthin about 35 days ago. After about two weeks I noticed my skin getting dry which is weird because I've always had oily skin. I figured it was due to the very cold winter here in PA but it got so bad I could just scratch my face lightly and skin would peel up! I realized it had to be the Astaxanthin. So I backed off to taking 5mg every other day and skin is good now.

    I am very interested in DIY Astaxanthin Cream.

    I'm wondering is the Astaxanthin from Skinactives the natrual one or synthetic?

  • February 22, 2012

    by Raychel

    FYI I searched around on astaxanthin and found the "Derma e" brand which sells astaxanthin (and other) based skin care lines much cheaper on, based on the ingredient list it contains the "Haematococcus Pluvialis" form of astaxanthin which an earlier poster mentioned was the one to buy.

    I just started taking 10mg astaxanthin daily. How long before I notice actual facial skin improvement for smoothness, diminishing of existing wrinkles, and reduction of redness or "the sunburn look". I do have moderate acne.

    i found the skinactives site on my own recently and bought the astaxanthin to put in my own creams. i also take it as a suppliment. it has really helped my psoriasis and i've noticed my skin looking fuller on my face. i'm only 31, but i have a family history of early collagen degeneration (getting wrinkly real young), so in treating my psoriasis i've helped my healthy skin too. the 5 mL that you get from the 14.50 at will last a LONG time. an 8th of a teaspoon will be more than sufficient for a 16 oz bottle of lotion. it's VERY orange.

    not all astaxanthin is created equal. always look for an astaxanthin extracted from haematococcus pluvialis algae, such as AstaREAL brand. If the material is just described as "astaxanthin", it may be synthetic (petrochemical derived) and not all natural.

    While journeying through a wealth of obscure knowledge, I took a detour via cosmetica and chanced upon what appears to be, to me, a possible treasure - Bella Pelle's iSoothe+. Not only does it contain astaxanthin, it also boasts matrixyl 3000, spin trap, syn-coll, l-ascorbic acid, MAP, & pyrus malus (apple) fruit extract, witch hazel, and something I know little about, melitane. I was wondering if anybodyelse has tried this, and if so, is it any good?

    Hi Kathy-
    I wouldn't recommend mashing up a nutritional supplement and putting it on your face, since it is rarely clear what else is in the gelcap and at what concentrations. However, here is a site that sells pure astaxanthin (for only $14.50!), which you can add to your serum or cream:

    Hey Copley,
    Could I make my own Astaxanthin antioxidant cream by squeezing one of their gelcaps into an emollient base? got a recipe?
