If there is one product that is held most commercially viable and has a long history of treating wrinkles, then it would be Retin-A. In fact, this product is one of the pioneering products that shaped the beauty and cosmetic industry.
Retin-A is a topical cream that promises to rejuvenate the skin and reverse damage caused by harmful UV rays of the sun. Over 30 years ago, Retin-A was developed as an anti-acne care regimen and found that its formulation can effectively enhance the 
skin’s appearance and texture.
Retin-A (generic name: tretinoin) is derived from one important vitamin – Retinol or vitamin A. Studies show that skin cells possess what is known as retinoid receptors that can help regulate function of the skin cells. As we age and as we expose our skin and body to damaging rays of the sun and unhealthy habits, the cells start to mutate and behave strangely. Retin-A comes into play by normalizing the function of the cell so it stays as healthy as possible.
Apart from skin smoothening, tightness and rejuvenation, this formulation has also been found to fade dark spots and freckles. Retin-A can improve cell healing and turnover, minimize the appearance of pores by shrinking dilated ones, and helps stimulate the formation and retain collagen, which is responsible for the skin’s structure and elasticity.
Retin-A thus works at a cellular level to improve the health of skin cells in an optimum ways. Today, Retin-A comes with a variety of strengths, depending on the needs of your 
skin. Although effective as a general formulation, certain skin types may become irritated by high amounts of tretinoin. Dermatologists usually recommend low amounts of Retin-A to allow the skin to get used to it, and then gradually increasing as the need calls for it.
Retin-A is perhaps one of the most important formulations in the skin care industry. It works to lessen wrinkles, provide smoother skin, lessen pigmentation, reverse sun damage and tighten pores. There are other similar formulations today out in the market that may just work as well as this, but remember that it was Retin-A who did it first and does it best.
