Even when you have by no means heard of astaxanthin as a beauty ingredient, you might be prone to have come throughout it often with out realising it. Astaxanthin, pronounced “asta-zan-thin” is a compound present in some aquatic microalgae and is liable for colouring seafood like shrimp, crab and lobster shades of orange-red to pink, in addition to the plumage of flamingos.
These are examples of astaxanthin at work. However, what precisely is it, and the way does it get from the seas into our cosmetics? And why is astaxanthin a trending beauty ingredient now? All these questions and extra, we reply on this brief information to this most fascinating and vibrant of beauty elements.
Astaxanthin is a marine xanthophyll (a category of oxygen-containing carotenoid pigments) and a member of the terpene group of chemical compounds. It was initially remoted from lobster in 1938 (i). It’s a lipid- (oil-) soluble crimson pigment and strikes up the meals chain by colouring numerous shellfish and sea-living crustaceans that feed on the astaxanthin-rich algae. In reality, most orange, pink and crimson marine organisms include astaxanthin.
It’s biosynthesised by microalgae, micro organism and yeast, and may be present in nature in addition to be made by chemical synthesis. In nature, it’s produced in sure freshwater microalgae (primarily, Haematococcus pluvialis) and yeast fungus once they expertise harsh environments comparable to elevated salinity, and excessive weather conditions comparable to extreme daylight or lack of oxygen.
Now you can make the hyperlink between flamingos and astaxanthin; these birds prefer to feed in marshes the place the algae, that are beneath stress in low-oxygenated, shallow water and from intense daylight, produce astaxanthin as a protecting mechanism.
Whereas we’re on the subject of bizarre compounds, you could be fascinated about studying about ectoine which additionally has properties of eager curiosity to beauty science analysis. It’s produced by water-living, single-cell micro organism as a defence mechanism in harsh weather conditions.

By now, you’ll now be questioning what the protecting advantages of astaxanthin are for the algae and if these prolong into its function as a beauty ingredient.
The microalgae produce astaxanthin for its photoprotective and antioxidant capabilities. It is for that reason that astaxanthin is being researched for its results on the pores and skin’s physiology as a potent beauty – and in addition nutraceutical – ingredient with the potential to supply the identical photoprotective, antioxidant and in addition anti-inflammatory advantages to our pores and skin.
Astaxanthin shares traits with different carotenoids we’re conversant in for his or her skincare advantages in botanical cosmetics, comparable to lutein that we discover in vegetation like tomatoes, and β-carotene in carrots. Nevertheless, astaxanthin shows better bioactivity – specifically a far greater antioxidant exercise – on account of its distinctive chemical composition (ii).
Medical research have indicated that astaxanthin’s antioxidant exercise works at numerous levels within the development of pores and skin harm attributable to reactive oxygen species (ROS) generated by UV rays and air pollution. ROS are a explanation for collagen and elastin depletion and have an effect on the pores and skin’s capability to restore itself.
Whereas some research examined astaxanthin as a dietary complement together with its results in topical utility, there may be proof to recommend that astaxanthin as a pure UV-blocking agent would have an effect on lowering the pores and skin’s indicators of photoageing, comparable to untimely wrinkles and sagging (iii), when included in topical beauty formulations. It seems that astaxanthin presents quite a few potential skin-beneficial results together with slowing collagen and transepidermal water loss, mitigating hyperpigmentation (darkish spots) by supressing melanin manufacturing, and stalling the development of wrinkle depth. It’s thought of far simpler than vitamin E, which is usually added to beauty formulations as an antioxidant.
There may be quite a lot of analysis on-line about astaxanthin, however keep in mind you could’t ascribe outcomes primarily based on its use as an orally-consumed complement to its results when topically utilized. It has been authorized as a dietary complement for sure dosages and course durations in Europe, Japan and the US for over 20 years (iv). Typically, beauty provider data comes with the phrase “potential” to explain astaxanthin’s beauty advantages.
Some research conclude that additional analysis is required to find out the extent of astaxanthin’s advantages when utilized in topical cosmetics, however findings comparable to astaxanthin giving rise to “vital discount of wrinkles and puffiness on the decrease eye and cheeks after two weeks of [topical] use” (v, vi) are encouraging.
The right way to use astaxanthin in formulations
Astaxanthin is a really highly effective carotenoid colourant, as you may need guessed from its means to maneuver by means of the meals chain colouring every thing from salmon flesh to flamingo feathers. It’s efficient at minuscule quantities in your formulation.
Types of astaxanthin
We talked about earlier that astaxanthin is a lipid and is a darkish crimson color. Sometimes suppliers supply it as an extract of the algae (Haematococcus pluvialis) in a provider oil of between 0.02% as much as 5%; the latter share is usually present in oils like safflower.
On this viscous, oleoresin kind, you want to add it to your lipid section and under 40°C. Just like the antioxidant vitamin E, it’s added within the heat-sensitive section to forestall its degradation. Given its colourant properties, we advocate together with the 5% astaxanthin oleoresin in your formulation between 0.01-0.05%. Learn your provider’s really helpful utilization ranges and first run some assessments of astaxanthin in an affordable provider oil to find out the way it performs earlier than you embrace it in a system.
As a sign, one our tutors used 2.5% of a 0.2% astaxanthin oleoresin which equates to 0.005% astaxanthin in an emulsion and the tip end result was a light-pink product. The picture under reveals astaxanthin in its oleoresin diluted kind in a provider oil and used at 0.07% in a sapogel masque and an oil. You’ll be able to see how highly effective a colourant it’s.
It’s possible you’ll discover astaxanthin diluted in provider oils as an oleoresin, or in a lipid-soluble, dry-powdered kind. You can even discover it as a microalgae water-based extract, however it’s possible that any aqueous model you discover suppliers providing shall be vulnerable to sedimentation. Some water-soluble types embrace an emulsifier or solubiliser. All the time ensure which kind you might be sourcing and seek advice from your provider for really helpful utilization ranges and any formulation directions. Once more, do assessments to work out the perfect quantity on your desired formulation – and its color – all the time staying inside provider utilization tips.
