What I like about DHC products is their simple formulation. Virtually no irritants.
The claimed ingredient here is ubiquinone, another name for coenzyme Q10. It is a vitamin-like substance found in human cells and may have skin benefits and reduce the appearance of wrinkles. Also it has some antioxidant and anti-inflammatory effects.
Another potent ingredient is olea europaea (olive) leaf extract. Used in cosmetics it is specifically effective in repairing skin damage caused by UV radiation and assisting wound healing. The oleanolic acid and flavonoids in the extract stimulate blood circulation in the skin, promote regular growth and thus promote a smooth and clear complexion.
The rest are a few well-intended ingredients but not fully delivered. For example willow bark is the precursor of salicylic acid when eaten. But on the skin the chance of it turning into salicylic acid is almost to none. However it may have some anti-inflammatory benefits for skin. Biotin is also known as vitamin H, a water-soluble vitamin considered part of vitamin B group. Biotin is necessary for the metabolism of carbohydrates, fats, and amino acids (the building blocks of protein). However, it has no reported benefit for skin when applied topically. Cyanocobalamin is a form of B12 that's readily absorbed. B12 may be effective in the treatment of psoriasis. But no solid evidence has shown any skin benefits of vitamin B12.
