1. Astaxanthin Overview
Where to buy Astaxanthin with lowering Astaxanthin price? Where to find information of wholesale Astaxanthin and Purchase Astaxanthin for sales? As Astaxanthin manufacturer & supplier, BFSTAR is your best choice.
Astaxanthin is a natural carotenoid, widely found in aquatic animals, bird feathers and micro algae. It has strong antioxidant activity. But because of its poor water solubility and stability, astaxanthin is very easy to be oxidized and decomposed when encountering light, heat, oxygen, etc., which reduces its bioavailability. BFSTAR develops astaxanthin water emulsion by nano-emulsification technology that overcomes the above shortcomings. Astaxanthin water emulsion is easily absorbed by skin, and still has a strong anti-oxidation property.
Transdermal tests have shown that astaxanthin water emulsion can change the tight structure of skin stratum corneum. It can promote the penetration and absorption of astaxanthin, and increase the retention of astaxanthin in skin. Cytotoxicity and skin irritation experiments proved that astaxanthin water emulsion has better safety at a certain concentration, and there is no obvious irritation to human skin.
As the strongest antioxidant agent in nature, astaxanthin’s antioxidant activity is 1000 times that of vitamin C. Astaxanthin can effectively protect the skin from ultraviolet (UVA, UVB) damage. Its super strong ability to eliminate free radicals can prevent skin cells from being damaged by free radicals, and reduce wrinkles and fine lines. As a super anti-oxidant agent for cosmetic, astaxanthin is widely used in various cosmetics such as cream, serum, eye cream, facial mask and lotion.

2. Astaxanthin Source
The source of astaxanthin is mainly divided into chemical synthesis and natural extraction. Astaxanthin is the final product of carotenoid synthesis, which is difficult to synthesize artificially and is mostly in cis structure. The US FDA only approves the trans-structure astaxanthin for industrial production. Natural extraction methods usually come from aquatic products, such as shrimp and crab shells, algae, etc.
Natural astaxanthin mainly comes from Haematococcus pluvialis. The content of astaxanthin in Haematococcus pluvialis is 1.5%-3.0%, which is regarded as a “concentrate” of natural astaxanthin. Haematococcus pluvialis is considered as the best organism to produce astaxanthin in nature.

4. Astaxanthin Benefits
- Anti-oxidation & Anti-aging
The antioxidant activity of astaxanthin is equivalent to 10 times that of β-carotene and 550 times that of vitamin E. Astaxanthin can significantly reduce the damage of ROS and NMP to skin collagen and dermis elastin, thus ensuring the normal metabolism of skin. The structure of astaxanthin makes it easy to react with free radicals to scavenge free radicals, and play an anti-oxidant effect. Used in cosmetics, astaxanthin can prevent and delay skin aging and reduce the production of wrinkles and fine lines.

Astaxanthin is a very effective photo-protective agent. It has its unique molecular structure. The absorption peak of its substance is about 470nm, which is similar to the UVA wavelength (380-420nm). Therefore, astaxanthin can absorb a large amount of UVA, which can effectively prevent ultraviolet radiation and eliminate free radicals caused by ultraviolet, thereby reducing the damage of ultraviolet rays to skin. In addition, astaxanthin can quickly restore skin damaged by UV burns.
