Retin-A is the best ingredient still

Vision

Light sensitive tissue lining called vertebrate retina is placed in the inner eye's area. The image we receive is due to the eye optics that works in the same manner as the camera film. The nerve impulses are triggered by the electrical and chemical events, which are provoked by the lighting bouncing of the retina. Brain receives these nerve impulses by the optic nerve and fibers. The retina is a part of the central nervous system and it can be non-invasively visualized. There are few layers of neurons, of which this complex structure comprises. Synapses are interconnected in this structure and photoreceptor cells of this structure are the light-sensitive neurons. Cons, which are responsible for color perception and vision during the daytime, and the rods, which are responsible for the black and white vision and dim light vision, are two types of these cells. There is a third photoreceptor, which is responsible for the reflexive response associated with the bright light and it is called photosensitive ganglion cell.

Retin-A

Retin-A is maybe the best ingredient included in the anti-aging products, due to the generic formulations and strength of the products given by prescriptions. Retinol is the same thing as Retin-A, but it is a bit milder and it can be found in department stores and drugstores. Wrinkles are one of the biggest problems among women, and dermatologists are looking for an ingredient that will eliminate this problem. Retin-A is probably the ingredient which is associated with every successful product on the market. We can say that advertisements regarding the efficacy of the products that do not have this ingredient are probably not true. Acne problems were the focus of the scientists who included the Retin-A in the treatment of this problem, and this was 20 years ago. In this time, it made the skin glow, smooth and improved the skin texture with reduced wrinkles and spots. There is regeneration on the cellular level of the skin and this is the reason for such excellent results. The cellular level is what the retinol works on as well and its regular use will surely increase the collagen production, which provides the firm and elastic skin. Collagen is very important in the fight against aging and it can reduce wrinkles. Retin-A is really efficient and it will reduce the chances of developing blackheads and whiteheads because it prevents the clogging of the skin pores. Some studies have even shown that after two years of retinol use, you can even treat precancerous skin cells.
