I have been using Tretinoin for many years, but I saw an ad for Nava MD and wanted to give it a try. I like the fact that I don’t have to go see a dermatologist to get a prescription. The Tretinoin that I received from Nava MD was mixed with Niacinamide, which helps prevent some of the unwanted side effects that normally come with Tretinoin use. I love the texture and consistency of their formula; it almost feels like a light powder/cream, in a way. I do wish it was easier to manage my subscription on their website. I don’t like the fact that I have to either call or email customer service to modify my subscription. I also wish they would use a different bottle. When I get to the end of any skincare product, I like to open up the packaging to scrape the product out so I don’t waste any of it. However, it is impossible to take the top off the base of Nava MD’s bottle. While their prices are comparable to similar companies, I think they are all overpriced. With those similar companies, they will include a face cleanser and moisturizer, but you don’t get anything “extra” with Nava MD. I found an American online company where I can get a large tube of Tretinoin for $10 with my insurance card. I can also get a prescription from my dermatologist and purchase the Tretinoin from the pharmacy for less than $30 out of pocket. Side note: I was trying to give this review three stars, but it was automatically adjusting itself to a five star review.
