Vitamins A and E and coenzyme Q10 are common ingredients in anti-ageing cosmetic products. Within this study, we evaluated the quality of commercial cosmetics with vitamin A (35 products), vitamin E (49 products), and coenzyme Q10 (27 products) by using validated HPLC-UV methods. Vitamin A was deter ...

Vitamini so skupina organskih spojih s številnimi specifičnimi funkcijami v človeškem organizmu. Vitamine delimo na hidrofilne (vodotopne) vitamine - C in vitamini B kompleksa ter lipofilne (maščobotopne) vitamine - A, D, E, K. Ker jih naše telo praviloma ne more sintetizirati, vitamine uvrščamo med ...

Koencim Q10 in vitamin E sta lipidotopna antioksidanta, ki koži pomagata predvsem pri odstranjevanju reaktivnih kisikovih zvrsti, zato sta pogosti sestavini »anti-age« kozmetike in sta v izdelkih pogosto skupaj. Ker v nobenem izdelku, ki ima navedeno prisotnost vitamina E, njegovega derivata ali CoQ ...

Vitamin A je pogosta aktivna sestavina v kozmetičnih izdelkih za zrelo in aknasto kožo. V kozmetiki so najpogostejši predstavniki vitamina A: beta karoten, retinol, retinal in retinilni estri nasičenih in nenasičenih maščobnih kislin. Retinojska kislina je edina biološko aktivna predstavnica vitamin ...
