What Is Astaxanthin?
Astaxanthin is a pigment molecule that is a member of the carotenoid family found in certain marine/freshwater algae. In simpler words, it is the yellow, orange, and red pigments that are produced by plants, algae, and bacteria.
One of the reasons why it has gained traction is because it is a potent antioxidant. In other words, it is helpful for addressing all kinds of skin issues – reducing skin wrinkles and age spots, enhancing skin elasticity and texture, and increasing the moisture content of the skin (3).
Now, let us look at the benefits of astaxanthin and its uses in skincare.
Top 5 Benefits Of Astaxanthin For Skin
Astaxanthin has some great benefits for skin that are backed by scientific research. Research suggests that it has photoprotective, antioxidant, and anti-inflammatory properties (4). In a nutshell, if you have extremely dry and damaged skin, astaxanthin may just be the ingredient you need to add to your daily skin care routine. Here is a quick run-through of its skin care benefits:
1. Protects The Skin Against Free Radicals And Sun Damage
Oral astaxanthin supplementation can protect the skin against damaging UV rays by suppressing the cell damage that is caused by free radicals (5). In fact, this ingredient can even slow down the growth of skin cancer cells and help maintain healthy skin.
2. Reduces Dryness
According to a study conducted in Japan, astaxanthin aids in reducing the loss of skin moisture and improves the texture of rough skin (5).
3. Treats Inflammatory Skin Diseases
Considering that astaxanthin prevents the damaging effects of UV rays on the skin, this ingredient is an important component of several anti-inflammatory drugs that help treat inflammatory skin diseases such as psoriasis and atopic dermatitis (AD) (4).
4. May Prevent Wounds From Becoming Worse
According to research done on rats, astaxanthin has significant antioxidant properties that help activate the cellular antioxidant defense system. This helps in protecting the skin against early burn wound progression and accelerates wound healing (4).
5. Delays Skin Aging
Research also indicates that ASX may play a promising functional role in treating and preventing skin aging and promoting overall skin health (4). Using a topical cream containing ASX combined with other active ingredients can significantly reduce wrinkles and puffiness under the eyes and on the cheeks after two weeks of use (4).
6. Improves Skin Moisture And Elasticity
A study was conducted in Italy on women who were given 2 mg of ASX. After six weeks of ASX treatment, significant improvements were observed in their skin moisture levels and elasticity (4).
Now that you have a good understanding of astaxanthin’s skin benefits, let’s understand how to use it in the right dosage and with the right precautions to keep in mind.
How To Use Astaxanthin The Right Way
Astaxanthin can be used by people of all ages and skin types. It is particularly useful for people with sensitive skin, owing to its anti-inflammatory properties, which aid in reducing skin redness, sensitivity, and inflammation.
If you have dry and damaged skin, using astaxanthin the right way can make a big difference. This ingredient can be used twice every day – morning and night – in the form of a serum, moisturizer, or oil. Make sure to read the label and conduct a patch test to ensure that you are not allergic to ASX.
Astaxanthin pills can also be taken orally. You can take astaxanthin in doses of 4 to 40 mg daily for up to 12 weeks or 12 mg daily for 6 months. You can combine it with other carotenoids, vitamins, and minerals at 4 mg daily for up to 12 months.
To figure out the ideal dosage for your skin – when using either topically or orally – consult a dermatologist.
