Astaxanthin: The powerful antioxidant that protects your skin from ultraviolet radiation

Astaxantina: El poderoso antioxidante que protege tu piel de la radiación ultravioleta

Ultraviolet (UV) radiation is known to cause photoaging of the epidermis and skin cancer. Astaxanthin is an antioxidant that has been shown to be effective in protecting the skin from the harmful effects of UV radiation.

Introduction to Astaxanthin

Antioxidants and sun protection

Astaxanthin is a red-orange carotenoid pigment found in certain marine organisms such as microalgae, krill, and salmon. This potent antioxidant has gained popularity for its many health benefits, including protecting the skin from damage caused by UV radiation.

Study in SKH-1 mice

Method and study diets

In a study conducted on UV-sensitive hairless SKH-1 mice, they were fed six different diets containing 5 ppm beta-carotene, 10 ppm astaxanthin, or retinol. After 4 months, half of each group was exposed to ultraviolet light and sacrificed to measure the concentrations of putrescine, spermidine, and spermine in the epidermis.

Effects of astaxanthin on the production of polyamines

Putrescina

After irradiation, astaxanthin, alone or in combination with retinol, was found to be remarkably effective in preventing the increase in free putrescine after induced damage.

spermidine and spermine

Spermidine and spermine concentrations were also significantly lower in the astaxanthin-fed groups.

Comparison with other antioxidants

beta carotene

Beta-carotene is another antioxidant known for its protective properties against UV radiation. However, in this study, astaxanthin showed a stronger inhibitory effect on putrescine accumulation than beta-carotene.

Retinol

Retinol, a form of vitamin A, has also been studied for its skin-protecting properties. Although it demonstrated some efficacy, astaxanthin had a more potent effect in preventing putrescine buildup compared to retinol.

Astaxanthin and transglutaminase enzymes

specific action

The results of the study indicate that astaxanthin exerts a specific action on transglutaminase enzymes, helping to consume these polyamines in response to skin irradiation.

Additional Astaxanthin Benefits

Prevention of skin aging

Astaxanthin is known for its anti-inflammatory and antioxidant properties, which can help prevent premature skin aging caused by exposure to UV radiation.

skin cancer prevention

In addition to preventing skin aging, astaxanthin may also play a role in preventing skin cancer by protecting the skin from damage caused by UV radiation.

astaxanthin sources

Foods

Astaxanthin is found naturally in certain foods such as salmon, krill, microalgae, and crustaceans. Consuming these foods can help you get astaxanthin naturally and reap its benefits for skin health.
