  Adulthood is a period of self-discovery and progress. To project a positive image, increase confidence, and shine everywhere we go, we must first concentrate on skincare, and we can take better care of our skin if we understand the processes that lead to skin aging. Skin aging results from both internal factors like aging and external factors, mainly exposure to ultraviolet (UV) rays in sunlight. According to reports, sun exposure is responsible for over 80% of facial wrinkles. Sun exposure causes the skin to lose its elasticity, become rough, darken, create deep lines, and undergo harmful structural changes under the skin(1).

UV light and MMPs in the Degradation of Collagen:

  Matrix metalloproteinases (MMPs) are enzymes found in skin cells like MMP-1, MMP-3, and MMP-9 that degrade collagen. UV exposure increases free radicals within skin cells, stimulating increased production of MMPs. These enzymes act like scissors, cutting collagen in the skin. The destruction of collagen, the foundation of firmness and flexibility, leads to wrinkles and sagging. Besides increasing MMPs, UV light induces skin darkening by stimulating melanin granules and triggering the release of pro-inflammatory substances, contributing to collagen damage(2).

Fact: that Thailand has an average UV index value at level of 10 or is at a very high level

Protecting Skin from Sunlight with Astaxanthin

  To combat the oxidative effects of UV light that damage the skin, turning to Astaxanthin is an excellent choice. Astaxanthin, a red pigment from nature, holds the highest free radical-fighting power due to its unique molecular structure, providing comprehensive protection for cells internally and externally across the body.

  Research indicates that astaxanthin's anti-free radical properties can inhibit MMP-1 secretion and other inflammatory substances in UV-exposed skin cells(4). Clinical studies have shown that taking 6 milligrams of astaxanthin daily for six weeks can reduce wrinkles, increase moisture, and improve skin elasticity(5)(6). Thus, long-term Astaxanthin supplementation delays skin aging due to environmental factors and significantly reduces free radicals throughout the body, resulting in healthier, youthful-looking skin.

Fact: Astaxanthin's effectiveness in fighting free-radicals surpasses beta-carotene by 5 times, CoQ10 by 800 times, vitamin E by500 times, and vitamin C by 6,000 times!!!(3)

Results from using Astaxanthin:

  • Counteracts free radicals from sunlight, slowing skin degradation by safeguarding collagen from MMP enzymes.
  • Reduces inflammation, a factor contributing to wrinkles, maintains skin moisture, and promotes overall skin health.

Who Benefits from Using Astaxanthin?

  • Individuals seeking protection against sun-induced skin damage and darkening
  • Those who want to obtain youthful skin, reduce wrinkles, and care about their skin's health
