Hi Dr. How long can u use Renova, every and every?..Been using it for 4 yrs now i love the results....Is it a long term soulution?...

Tretinoin (generic name for Renova, Retin A, etc) is very safe long term.  It has been studied for over 20 years and millions of people use it regularly.  It helps with wrinkles, improves sun damaged skin, and helps to prevent skin cancer.  It’s hard to go wrong with it.  It may make you just slightly more sun sensitive.  You may want to stop it a week before a sunny vacation or times when you’re in the sun a lot like summer unless you are compulsive about sunscreen and hats.

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes! I have handpicked some of what I consider to be the best skin care products, and offer them for sale on SkinTour's shop. This is based on my team and I's testing and research at our clinic. Many of the products are in my own regimen. What could be better than using skin care products a dermatologist uses?!
