Skin is the largest organ in the human body. However, one important fact that many people do not know is that skin acts as a sensor and can get easily damaged or affected due to adverse weather conditions. Also, all the noticeable symptoms of aging first appear on the skin. In this regard, it is very much required to provide proper skin care so as to delay all the symptoms of aging and also to enhance the overall appearance of an individual. An important natural element that can significantly improve the vitality of the skin is vitamin A.
Vitamin A is highly beneficial is protecting the skin against the harmful UV radiation. In fact, Vitamin A is an important constituent in some good quality anti-aging and anti-wrinkle skin creams such as LifeCell Skin Anti-Wrinkle Cream. Vitamin A is available in the nature in the form of retinal or retinaldehyde. Apart from this, there are also certain other derivatives of vitamin A that are known as retinoids. Some good examples of retinoids are tretinoin and tazarotene. Each one of these derivatives has its own benefits.
1. Tretinoin: Commercially known as Retin-A, Tretinoin is the only topical agent that has been approved by USFDA for treating symptoms resulting due to photoaging. In fact, there are several reports that suggest the efficacy of tretinoin in improving skin damaged due to overexposure to sun and ultraviolet radiation. Also, Tretinoin enhances the natural glow of the skin and decreases symptoms such as wrinkles, facial lines, liver spots and roughness on the skin.
2. Retinol: Reports suggest retinol is almost as effective as Tretinoin in terms of improving skin quality. However, the disadvantage with retinol is that it is highly unstable and can get easily damaged with excessive ultraviolet radiation unless it is included in the formulation in combination with other ingredients such as vitamin C or E. As a result of this, retinal has not been approved by USFDA to be included in any over-the-counter skin product.
3. Tazarotene: This is another vitamin A that has been increasingly used in the treatment of skin conditions such as acne and psoriasis. However, USFDA has recently approved this retinoid derivative to be used in the treatment of wrinkles, facial lines and skin pigmentation.
Many prominent cosmetic companies, for example LifeCell, have increasingly advocated the use of vitamin A. However, an important that many manufacturers fail to mention on their products is that any of the vitamin A derivatives if used by pregnant women and those who are about to conceive can result in the occurrence of birth defects in newborn children. Here, such type of creams must be avoided by these categories of people.
