subject: Retin A - The Solution for Stretch Marks? [print this page] Retin-A stretch marks formulations may also initially cause skin to flake off and the treated area to become irritated. This is normal, but if the skin does not become conditioned to the treatment and 'settle' or stop flaking after a week or so, you will need to see your doctor or dermatologist to evaluate whether you need a weaker formulation or to stop the treatment altogether. You may also experience sensitivity to sunlight, and so it is recommended you avoid direct sunlight on the treated area, or use a strong UV protection sunscreen on the treated areas in situations where sunlight cannot be avoided.
