Good sources of Astaxanthin include crustaceans, and marine algae. 

In clinical trials, Astaxanthin has been shown to boost skin moisture levels, skin moisture retention, and elasticity. It promotes skin smoothness, reducing wrinkles and fine lines. Carotenoids are known for their strong photo-protective properties and strong antioxidants activity that increase the skins’ UV blocking properties, and ability to combat effects of free radicals (4).



Beta-carotene is the yellow/orange pigment that is known as carotenoids (5). It gives fruits and vegetables their rich colors. Our bodies convert beta-carotene into Vitamin A which is needed for a healthy skin.

Soy Isoflavones

Soy Isoflavones made up of two compounds called Daidzein and Genistein, fall under a group of chemicals called Bioflavonoids. Soy Isoflavones is derived from soy, and relative to its action in the body, it seems to imitate the hormone estrogen.

Soy Isoflavones have been linked with skin benefits and they improve the skin elasticity, collagen synthesis, increase tissue hydration, and reduce the appearance of wrinkles. with reduction of breast cancer (37). Similarly, isoflavones act as powerful antioxidants that can reverse the appearance of the skin due to aging that may be caused by free radicals caused by UV radiation.

Genistein is the most abundant isoflavones found in the soy product. It resembles the human estrogen, and for this reason it’s classified as a phytoestrogen but it’s also an antioxidant (26).

Since it’s a phytoestrogen, Ginistein mimics estrogen, and for this reason, it can be used to remedy conditions triggered by declining or worsening level of estrogen such as osteoporosis.


Vitamin A (as Beta Carotene)

Niacinamide contains two major enzymes (NADH and NADPH) that help in the production of lipids and celular energy responsible for cell growth. Sufficient supply of both enzymes helps the skin to create an external barriers that influence the aging process (40). As we grow older, the level of these enzymes decline, therefore if used as a supplement, vitamin B3 can slow down the aging processes.


Vitamin B5 (Pantothenic Acid)

Vitamin B5 (pantothenic acid) is one of the 8 B vitamins that are found in meat, cereal grains, eggs, milk, vegetables, and legumes. Vitamin B5 is commercially available as D-pantothenic acid (41).

When creams, lotions or ointments that contain provitamin B5 are applied to the skin, they are converted to vitamin B5 (Pantothenic acid) which has strong abilities to soothe, moisturize, and heal the skin.

Some studies have shown that Ascorbic acid (45) may help prevent ultraviolet-induced skin damage. Aging and excessive exposure to ultraviolet rays lowers the level of vitamin C in the body (46). Therefore, supplementation might be necessary.


Vitamin D3 (as Cholecalciferol) 

Vitamin D3 is a unique dietary supplement that is found in a few foods including oily fish such as tuna, mackerel, and sardines (47). Unlike vitamin D2 which is obtianed from the diet, Vitamin D3 (47) is synthesised in the body when the skin is exposed to ultraviolet radiation from the sun.
