The Skinny on Topical Retinoids

Topical retinoids (Retin A, Renova, generic tretinoin)are the only prescription medications proven to reverse sun damage.

Tretinoin causes increased collagen production in the dermis, and it inhibits the enzymes that normally break down existing collagen in your skin. Those enzymes that break down your collagen are activated by UV radiation from the sun or other sources. Tretinoin also causes increased synthesis of elastin (the protein that makes up the elastic fibers in your skin) and it stimulates angiogenesis, the formation of new tiny blood vessels to bring more oxygen and nutrients to your skin cells every moment of your life. It decreases skin cell adhesion, making the upper layers of dead skin cells slough off more quickly, revealing smoother, fresher skin. Finally, it is responsible for thickening of the epidermis. Yes, that's correct. There is a pervasive myth that topical retinoids thin your skin, and they do thin the upper layer of dead skin cells (the stratum corneum), but they actually make all the other layers thicker. Because our skin becomes increasingly thinner with age, a medication that thickens the epidermis is a Very Good Thing.

More is better, up to the point at which your skin can tolerate the medication without too much redness or peeling. The original studies were done with low percentages (0.02%-0.05%), but there has been a study since then proving that 0.05% is better than 0.01%. So 0.1% (the highest available strength) is probably even better, although there has been no actual study to confirm this. Importantly though, the medication only works if you apply it regularly. So if you experience too much irritation with the higher strengths of tretinoin, it is better to use a lower prescription strength retinoid or even an over-the-counter professional strength retinol Every Single Night for years than to use the more irritating, higher strength creams sporadically.

You have to keep using it. Studies show that people who stop using the medication revert to the expected level of sun damage for their age within 1 year of stopping. Good stuff, these retinoids. What? You're not using one?? Do come talk to me and we will see which one is right for your skin.

Hello Web Admin, I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword....wait there's even more Now what if i told you there was a simple Wordpress plugin that does all the On-Page SEO, and automatically for you? That's right AUTOMATICALLY, just watch this 4minute video for more information at. Seo Plugin

like yours. It is beautiful price enough for me. In my opinion, if all webmasters and bloggers
made excellent content material as you did, the web
shall be much more helpful than ever before.

Hey! I know this is sort of off-topic but I had to ask. Does
building a well-established website like yours require a large amount of work?
I'm completely new to running a blog but I do write in my diary every day.
I'd like to start a blog so I will be able to share my
personal experience and views online. Please let me
know if you have any recommendations or tips for new aspiring blog
owners. Thankyou!

Have you ever considered about adding a little bit
more than just your articles? I mean, what you say is important
and everything. But just imagine if you added some great photos or videos to give your posts more, "pop"!
Your content is excellent but with images and video clips, this site could undeniably be
one of the greatest in its niche. Very good blog!
