Retinol is not new to the beauty market by any stretch. Retinoids (which include both over-the-counter Retinol and its prescription counterpart Retin-A) were initially used to get rid of acne, blackheads and dead cell buildup in pores. However, it was also found to be incredibly effective when it comes to anti aging skincare.

Here are 5 FAQs about Retinol you can use to to decide if it’s the right fit for you (hint: it probably is!).

Question 1: What is Retinol, and what are the major anti-aging benefits?

Answer 1: Retinol is a compounds in the Vitamin A family. There are 2 major ways retinoids are available in skincare products: Retin-A and Retinol.  Retin-A is the prescritption form, and has been shown to reduce fine lines, smooth skin’s texture, and help with hyper pigmentation. Retinol is the over-the-counter form. The benefits of Retinol are that it can be used without a prescription, and it’s a less irritating form of the Vitamin A.

Question 2: How does Retinol work to reduce the appearance of wrinkles?

Answer 2: Retinols work by promoting promoting surface skin cells to turn over quickly, making way for new cell growth underneath, similar to the way an exfoliator would work. If Retinol is able to penetrate (like it would if applied using a Serum), it can slow the breakdown of collagen, and thicken the deeper layers of the skin where wrinkles usually get started. This helps keep fine lines at bay.

Because Retinol encourages improved cellular function and turnover, it can also improve skin texture, brown spots and hyper pigmentation.

Question 3: How should I apply Retinol to my skin?

Answer 3: The most common ways to apply Retinol topically are using a cream or a serum. The good thing about Retinol Serums is that the molecules tend to be smaller, giving them a better chance of penetrating deeper into the skin. Additionally, Sano Naturals Retinol Serum contains Botanical Hyaluronic Acid and Organic Aloe to help sooth and prevent irritation that can occur with Retinoids, and also encourage absorption.

Question 4: When and how often should it be applied?

Answer 4: A good rule of thumb, especially for users new to Retinol, is to apply a Retinol-containing Serum every other night to start. Over time, you can work up to every night. Results can be seen in about a week, or could take up to 8 weeks. A little goes a long way, so start out gradually. Retinoid containing topicals should be used primarily at night because retinol is photosensitive.

Question 5: Is there anyone who shouldn’t use Retinol?

Answer 5: People with rosacea or eczema may not be good candidates for retinol-containing products. The best advice we can give is to always check with your dermatologist before starting any new skincare routine, and always use a retinol serum in tandem with a moisturizer.
