Tretinoin (Renova and Retin-A).
Retinoids, such as tretinoin or retin-A, are retinol derivative drugs. In most of the cases, they can increase collagen  synthesis and protect the existing collagen from being affected by the sun light. Renova and Retin-A are tretinoin creams that have been approved by the Food and Drug Administration (FDA) to be used for treatment of acne vulgaris and skin problems due to exposure to the sun.
Tretinoin preparations can reduce fine wrinkles and liver spots, and prevent any further skin ageing. Tretinoin, apart from boosting collagen synthesis, increases the production of new cells, resulting in thicker and healthier skin. Within the first six weeks of treatment, the skin seems largely improved. It gets smoother, far less wrinkled and nearly free of dark spots. The overall improvement takes place within the first six months of treatment. Beyond this point the use of the cream aims to maintain the achieved results. Discontinuation of the treatment may cause gradual return to the skin original state.
According to a study taken place in 1991 and the results published in the Archives of Dermatology, retinoids can decrease pigmented spots up to 37%, wrinkling up to 27.10% and skin roughness up to 29.30%, if used once a day for six months. The overall improvement reached the 79% of the cases. A new research done in 2006 verified and boosted the above beneficial effects.
Retinoids as derivatives of retinol can play an important role in treatment of acne vulgaris, when applied topically. In fact, Renova and Retin-A are prescribed extensively by dermatologists for this purpose with significant results. For more information check the Acne Vulgaris Medications page.
