45gm Tube with 0.1% Tretinoin Gel with Microspheres
Manufactured by Janssen-Cilag Pty Ltd
What are microspheres and how does the Microsponge� system work?
Microspheres are round microscopic particles made of synthetic polymer. These particles hold tretinoin in the Microsponge� system, and the microsponges with the drug are formulated into a gel. The microspheres hold the medication in reserve, allowing the skin to absorb small amounts of tretinoin over time. Dermatologists who conducted the clinical studies believe this may be why most RETIN-A MICRO patients experience little or no irritation. The microspheres themselves remain on top of the skin and are easily washed off when you shower or wash your face.
Use
Retin-A Micro has several uses. Retin-A is widely and popularly used for the treatment of acne, and can also diminish the visible signs of ageing � removing lines and fades sun spots. It is also used in conjunction with topical hair loss medications. Retin-As main active ingredient, Tretinoin works by increasing the turnover of skin cells and speeds up the shedding of dead cells.
