Skin aging: a natural process, but factors such as oxidative stress, sun exposure, air pollution and poor nutrition can accelerate it.
As a result, the skin loses its elasticity, wrinkles and dark spots appear, and dryness and irritation develop.
New studies: suggest that dietary supplements with antioxidants, such as astaxanthin, may slow down the aging process and improve skin health.
Astaxanthin: an antioxidant 600 times more powerful than vitamin C and 500 times more than vitamin E.
It is found naturally in algae, salmon, crabs and flamingos.
Current study: Examined the effects of astaxanthin consumption for 4 weeks on the morphology (structure) of residual skin surface components (RSSCs).
RSSCs are dead cells that accumulate on the surface of the skin and can provide information about the health of the skin.
The study included 31 subjects: over the age of 40 from whom RSSCs and blood samples were taken at the beginning and end of the study.
The results:
- Significant decrease in malondialdehyde (MDA) levels
in plasma, indicating a decrease in oxidative stress.
MDA is a toxic byproduct of metabolism, and high levels of it are associated with aging and various diseases. - Significant decrease in the breakdown of corneocytes (skin cells) in RSSCs.
Corneocytes are the outermost cells of the epidermis, and are responsible for the outer barrier of the skin.
Increased decomposition of them causes dryness, peeling and irritation. - Significant decrease in microbial presence in RSSCs.
Excessive growth of bacteria on the surface of the skin is associated with inflammation, acne and other skin problems. - Significant increase in fat droplet size in RSSCs.
These drops of fat contribute to the smoothness and elasticity of the skin.
These effects were stronger: among obese subjects (BMI > 30).
This may be because obese people are more prone to oxidative stress and inflammation, and consuming astaxanthin may help neutralize free radicals and improve skin health.
Conclusions:
- Consumption of astaxanthin for 4 weeks reduces oxidative stress and leads to facial skin regeneration.
- These effects are more pronounced among obese subjects.
- This study suggests that astaxanthin may be an effective nutritional supplement for slowing skin aging and improving its health.
Important to note:
- This is a preliminary study, and further studies are needed to confirm the findings.
- It is recommended to consult a doctor before taking nutritional supplements, and especially in cases of taking medications at the same time.
