Retin A Information
What are the three uses for Retin A (Tretinoin)?
Treatment of acne vulgaris, treating the visible signs
of aging by diminishing the lines on the face and fading aging spots,
initial studies have shown that tretinoin appears to enhance the effects
on minoxidil for the treatment of alopecia or hair loss.
How does Retin A help with alopecia or hair loss?
Topical tretinoin appears to increase the beneficial effects of minoxidil,
and it is thought that this is due to increased absorption of minoxidil
through alteration of the stratum cornum barrier. One study showed a
triple absorption with 0.05 tretinoin as compared with a control vehicle.

What do I need to watch for while I use Retin
A?
Your acne may get worse during the first treatment
period and should then start to improve. It may take 2 to 12 weeks before
you see the full beneficial effect.
Do not wash your face more than 2 or 3 times a day,
unless told to by your physician. Do not use the following products
on the same areas that you are treating with tretinoin, unless otherwise
directed by your physician: medicated cosmetics, cosmetics that dry
the skin (especially products that contain alcohol), abrasive soaps
or cleaners, and any other acne preparation or skin treatment. If you
use these products in combination with tretinoin they can cause severe
skin irritation. You can use non-medicated cosmetics (unless your physician
instructs you otherwise); wash the skin well before applying Retin A.
Tretinoin can increase sensitivity of the skin to
sun or UV light. Keep out of the sun, or wear protective clothing outdoors
and use a sunscreen (SPF 15 or higher). Do not use sun lamps or sun
tanning beds or booths.
Special warnings concerning Retin A?
Do not apply the medication close to the eyes, mouth,
angles of the nose, and/or mucous membranes. The medication may cause
a brief feeling of warmth or slight stinging when applied. If it causes
an abnormal irritation, redness, blistering, or peeling of the skin,
notify your doctor. He may suggest that you use the medication less
frequently, discontinue use temporarily, or discontinue use altogether.
If a severe sensitivity reaction or chemical irritation occurs, you
will probably need to stop using the drug. Individuals with eczema or
other chronic skin conditions, use this medication with extreme caution,
as it may cause severe irritation.
