Retin+Erase contains the maximum one percent HPR, so it's five times stronger than the strongest granactive retinoid from The Ordinary! Consider this one if you're looking to treat signs of aging but get too much irritation from retinol.I think it's best for treating the first signs of aging in acne-prone skin-I got really good results from this product! but no word yet on how strong it is compared to HPR. Retinol Reform contains retinyl palmitate, a retinol ester that is weaker than retinol.The last thing I want to address is how these formulas compare to my two other retinoid recommendations, Resurface by Shani Darden Retinol Reform (reviewed here) and CyberDerm Retin+Erase (initial review here). The latter is great because it's one of the only anti-aging products I've been able to tolerate around my eyes! Personally, what I am doing is using the Retinol 0.5% or 1% in Squalane all over my face, except for the eye area, where I'm applying the Granactive Retinoid 2%. Here's how I'd summarize the differences: There just isn't any data that compares the strength of HPR versus retinol. I don't think you can go wrong with any of the new products, which I would consider preferable to Retin-A due to these concerns.Īs for which active ingredient is "better" or "stronger," it's hard to say. I'm no longer recommending this product since I feel the other retinoid options are better, and I prefer to avoid ethyl linoleate (a linoleic acid ester that would be prone to oxidation).However, they still promise a 12-month shelf life. Since the formula does contain water, it would not be as stable as the oils.They don't disclose the concentration of retinol, but this would mean it is slightly stronger than the Granactive Retinoid 2% in Squalane. Contains 0.2 percent HPR, plus an encapsulated retinol.Some people get acne from cetearyl alcohol and carrageenan, though. Although squalane oil is usually not comedogenic, if you find it breaks you out, then you MIGHT tolerate this formula better.A moderate-strength retinoid with a lightweight creamy serum texture (not an oil).Not a new product-they just gave Advanced Retinoid 2% (originally reviewed here) a new name.The Ordinary Granactive Retinoid 2% Emulsion is. The Ordinary Granactive Retinoid 2% Emulsion Manjula Jegasothy, a Miami-based dermatologist, told Refinery29: "It is well-known that retinoid esters do not have as much efficacy in smoothing the epidermis and growing collagen in the dermis as pure retinol." Right now, there isn't any way of knowing what percentage of retinoic acid or retinol the HPR is equivalent to.ĭr. S. Just keep in mind that it is a new ingredient that is not as proven, as most of the research to date comes from its manufacturer. Unlike Retin-A and retinol, HPR is unique in that it produces little to no irritation. ![]() However, this action MIGHT interfere with the body's uptake of vitamin A (a very important metabolic factor), which is the reason I avoid Retin-A. HPR is said to be similarly active, since it does the same thing (and does not need to be converted, like retinol does). ![]() Retinoic acid, also known as tretinoin or Retin-A, is the active form of vitamin A, which binds directly to the skin cells' retinoid receptors. What exactly is Granactive Retinoid? It is a delivery system for the active ingredient hydroxypinacolone retinoate (HPR), which is a retinoic acid ester.
