Astaxanthin is a carotenoid and the highest grade product of carotenoid synthesis, which is dark pink and has a chemical structure similar to β-carotene. It is widely found in nature, such as most crustaceans and salmonids, plant leaves, flowers, fruits, and flamingo feathers. There are currently two production methods of astaxanthin on the market, one is artificial synthesis, the other is biological extraction, and the synthetic astaxanthin has many properties and other aspects compared with the natural astaxanthin gap. The synthetic astaxanthin is mainly chemically synthesized using carotene. In terms of antioxidant properties, safety, stability, and biological properties, there are many gaps between the biologically extracted astaxanthin. The US Food and Drug Administration (FDA) has banned chemically synthesized astaxanthin from entering the health food market. The production of astaxanthin generally tends to develop biological sources of natural astaxanthin, mainly from Haematococcus Pluvialis. At the same time, astaxanthin has shown strong antioxidant properties in scientific research and has become a huge potential molecule. It is no exaggeration to say that astaxanthin is the most powerful antioxidant found in nature.
The effect of astaxanthin in skincare products
Many skincare products containing astaxanthin on the market claim to improve wrinkles and repair damaged skin when applied to the face. So what is astaxanthin for? how much astaxanthin can be absorbed when applied to the face?
In fact, there is a basic principle regarding the absorption of skincare products. Only substances with a molecular weight of fewer than 500 Daltons (G/MOL) can penetrate the epidermis and reach the dermis to play a role. At the same time, the absorption of substances below 500 Daltons is still limited by many factors. Factors such as content, solubility, and thickness of the stratum corneum will affect its absorption effect. The molecular of astaxanthin is 598 Daltons. Therefore, the astaxanthin application method penetrates into the dermis to play an anti-oxidant effect, and the effect is very small.
Although some users say that they are very effective after using some astaxanthin products, other users say that they are insensitive to use. The reason is that on the one hand, it is because of the differences in the personal physique. On the other hand, even if it is effective, it cannot be proved that this effect is brought by astaxanthin. After all, these products contain more than one ingredient of astaxanthin. In summary, the antioxidant effect of astaxanthin as a skincare product is mostly a gimmick.
Application of Astaxanthin in Health Products
Judging from the current data, the safety of astaxanthin is guaranteed. It is an oxygen-containing derivative of carotenoids, which can effectively remove active oxygen in the body and has high nutritional and medicinal value.
1. Astaxanthin can increase the production of human immune globulin, thereby enhancing immune function.
2. light protective effect; Compared with β-carotene and lutein, astaxanthin can more effectively prevent the ultraviolet light oxidation of lipids, so the ultraviolet protective properties of astaxanthin play an important role in maintaining the health of eyes and skin, Astaxanthin has great potential as an edible photoprotective agent.
3. Prevent cardiovascular diseases; animal studies have shown that astaxanthin has the effect of significantly increasing HDL and lowering LDL, thereby preventing some cardiovascular diseases.
4. Maintain the health of the central nervous system; The experiment of feeding mice with natural astaxanthin shows that astaxanthin can pass through the animal's blood-brain barrier and produce antioxidant activity outside the barrier. Therefore, oral astaxanthin is a good way to prevent neurological diseases such as Parkinson's syndrome.
