How Does Retin-A Micro Work?

What is Retin-A Micro?

Retin-A Micro is a topical cream that can be used for the treatment of acne. It does not have any oil and can only be obtained with a prescription. It uses high doses of tretinoin, a vitamin that is commonly used in the treatment of acne. Since tretinoin in high doses can cause skin irritation, Retin-A Micro uses a unique method of delivery called the Microsponge system.

What is Tretinoin and How Does it Work?

Tretinoin is the acid form of vitamin A. It is also known as all-trans retinoic acid (ATRA). It is commonly used to treat a variety of skin conditions, including acne vulgaris and keratosis pilaris. Tretinoin works by regulating the growth of skin cells. Tretinoin helps skin cells grow and repair themselves. It can also help slow the signs of aging on skin as well as masking stretch marks. One of the dangers of using high doses of tretinoin is that it can cause dryness and increased sensitivity of the skin on which it is applied. It can also increase the risk of sunburn, so extra care should be taken to protect the affected skin from the sun. The irritation can also cause the skin to thin temporarily.

How does the Microsponge System Work?

Because tretinoin can irritate the skin, it is generally recommended to gradually increase the dose to minimize these effects. Retin-A Micro uses the Microsponge system, which uses microspheres. These microspheres are made out of polymers, which hold the tretinoin. This technique allows for a high amount of tretinoin to be held in reserve but lets the skin absorb it little by little, at its own pace. This helps prevent irritation and inflammation of the skin. The microspheres stay on the skin's surface and are removed whenever the affected area is washed. While Retin-A Micro looks like a cream, it is really a gel with the microspheres suspended in it.
