Benefits of Tretinoin.

First and foremost…..

• It Kicks Aging in the Ass

Tretinoin is considered the gold standard anti-aging ingredient in dermatology.
How effective is it, you ask? Check out what this 61 year old woman looks like after using tretinoin for 28 years! 

I KNOW RIGHT?! Like, zayum gurl! You looking GOOD.
Given, this is just one person. Maybe she just got lucky or eats kale for dinner. What do we know, right? Well, the scientific literature paints a similar picture!
For example, a very well controlled study involving 360 participants found significant improvements in fine lines and wrinkles after 24 weeks of using tretinoin cream 0.025%. Other studies have been replicated with similar findings. Despite most improvements occurring with fine wrinkling, a reduction in deeper wrinkles and tactile roughness was also observed.
On a side note, 0.025% tretinoin cream is on the lower end of the strengths available. Some people use a full 0.1% daily (that’s 4 times the potency)! However, using this high of a percentage may be unnecessary altogether.
One study found there was “no clinical or statistically significant difference” between 0.025% and 0.1% tretinoin after 48 weeks, besides the severity of irritation (0.1% tretinoin obviously being more irritating). So if you decide to buy tretinoin cream amazon for anti-aging purposes, know that you will still be getting the benefits with smaller dose prescriptions.
The assumption is that tretinoin works by tightening the skin and increasing collagen production, which leads to epidermal thickness.Collagen being a structural protein that provides strength, flexibility, and resilience to the skin.
Unfortunately this lovely protein decreases overtime and becomes a main culprit in aging. For some perspective, collagen production slows down by about 1% every year after a person turns 20. As a result, skin becomes less elastic and thinner with age, making it more prone to sagging and wrinkling.

Point being, the more collagen we can produce the more we slow down the aging process. Hence, why tretinoin is awesome — it increases collagen production!
Tretinoin also reverses photodamage (the adverse effects of sun exposure), and increases hyaluronic acid production in the epidermis. Hyaluronic acid is another necessary component of human skin. It speeds up wound healing and is a potent humectant that hydrates the skin by drawing water from the environment and dermis (deeper layer of skin). This in turn gives a “plumping” effect that reduces fine lines and wrinkles.

Perhaps you noticed how long the studies I listed above were (24 to 48 weeks respectively). This is because tretinoin works gradually over time. Don’t expect to see results quickly; this medication requires patience, time, and persistence!
On the upside, improvements never seem to slow down. In fact, one study found that there was still improvements being made in collagen organization and production after 2 years of continued use!
