Cellular turnover slows with age and new cells are generated less rapidly and remain on the skin longer. Retinoids (or Vitamin A) work by increasing cellular turnover in the skin. New cells are created more rapidly, progress to the surface of the skin more rapidly and are sloughed off more rapidly. This prevents or reduces many conditions associated with cellular build-up. Pigmentation is often reduced due to more rapid turnover and replacement of hyperpigmented areas. Retinoids play a critical role in skin growth, repair and epithelial cell differentiation. Additionally, when retinol technology is formulated in combination with glycolic acid, there is a synergistic enhancement and the overall results are greatly intensified.
