Vitamin A & Vitamin C

Vitamin A

Retinoids (a derivative of Vitamin A) are by far the most medically studied ant-aging vitamins.  (Vitamin A) Retin-A and Renova are examples of prescription-grade retinoids believed to work on aging skin by increasing collagen production and decreasing collagen breakdown, according to studies.    In a study published in the Archives of Dermatology in May, researchers from the University of Michigan found that 0.4% retinol lotion applied three times a week for 24 weeks yielded significant difference in skin wrinkling when compared with a similar lotion without retinol used on a separate group of people in the study. A prescription-strength Retin A product can produce measurable anti-aging results. Products on the market containing retinol include:

  • Vichy Reti-C Intensive Corrective Care (30 milliliters, $31)

  • Neutrogena Healthy Skin Anti-Wrinkle Intensives with retinol and antioxidants (Serum, 1 ounce, $16.99; Eye Cream, 0.5 ounce, $16.99)

  • Clinique Zero Gravity Repairwear Lift with retinol, antioxidants, and peptides (1.7 ounces, $52)

  • L’Oreal Advanced RevitaLift Double Lifting Gel (1 ounce, $16.99)

  • RoC Retinol Correxion Deep Wrinkle Serum (1 ounce, $19.99)

Vitamin C

Recent studies have found Vitamin C in the deepest layers of the skin.  This has led researchers to explore the effects of vitamin C on skin regeneration from the inside out.   As aging continues, the concentration of Vitamin C in the skin seems to wane.  Researchers now are faced with the challenge of creating a Vitamin C product using the active form that will last for a long period of time.  Most products contain little to no Active Form Vitamin C.   Products containing Active form of Vitamin C are:

  • Active C by La Roche Posay (30 ml, $49.50): This daily moisturizer helps to decrease fine wrinkles and contain: 5% Vitamin C (L-ascorbic acid) and a Thermal spring water
