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.
How effective retinoids can be?
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

Precautions and side-effects related to tretinoin (Renova and Retin-A).
Do not exceed the recommended daily dose. Tretinoin makes skin more sensitive to
sunlight and occasionally, it causes dryness. Thus, treatment with Renova or Retin-A must
be accompanied by the use of a good quality moisturizer and a sunscreen. Other side-effects of tretinoin
include redness, soreness and itching. In such cases, the drug must be used less
frequently.
Although Renova is sold over-the-counter, you will need a prescription for the Retin-A
purchase. Try the following links, if you want to read about the
