Retin A Micro is a topical, water-based gel available by prescription only. It has the same active ingredient as Retin A, tretinoin, but a completely different delivery system which provides the benefits of Retin A without so many of the drawbacks.
The active ingredient of Retin A Micro is tretinoin, a retinoid. In fact, Retin A Micro is remarkably similar to OrthoNeutrogena's other product, Retin A. What makes this product different is its delivery system.
Tretinoin is delivered directly to the skin cells using a technology known as Microsponge. Similarly to the claimed effects of Epiclear's liposome delivery system, Microsponge consists of microscopic spheres made of a synthetic polymer. Retin A Micro's tretinoin payload is contained in these microspheres. When the gel is applied to the skin, the microspheres penetrate the surface of the skin and are absorbed by deeper layers of skin cells.
Thus, the tretinoin is not absorbed by the top layers of the skin. This avoids much of the irritation and "shiny" appearance so characteristic of treatment with Retin A. Considering this information, Retin A Micro is more suitable for those with sensitive skin.
After cleansing the skin, Retin A Micro is massaged into the skin as directed by the prescribing doctor. Note that Retin A Micro can be applied directly to the skin after washing, rather than the 20-minute wait required before applying Retin A.
Retin A Micro seems to be a reasonably effective anti acne skin care product. Despite is side effects of irritation and sensitivity to the sun, Retin A Micro can provide assistance in removing particularly stubborn acne breakouts.
The inclusion of an anti inflammatory ingredient would be a welcome addition to the formula.
