    What the gurus are saying

    This amplifier serum is clinically proven to boost the effectiveness of actives that come after it, making everything from vitamin C to retinoids work harder. Dr. Shereene Idriss praises its hydroxypinacolone retinoate (HPR), an ester form of retinoic acid that delivers results without the irritation, while Caroline Hirons calls it her favorite product on the planet and uses it heavily enough that a bottle lasts four to six weeks. Apply it after cleansing and any acid treatment, then layer your actives on top.

    "I love hydroxypinacolone retinoate, which is basically the ester form of retinoic acid. It is available in Skin Rocks. It is a beautiful product and HPR is one of those derivatives that really makes a big difference and also helps with the quality of your skin without inflaming or irritating your skin and it is effective."

    "I love the Skin Rocks amplifier. It's clinically proven to amplify vitamin C, hyaluronic acid, peptides and vitamin A, you cannot go wrong. It's your first leave on product, you cleanse, use your acid, then put this on, and it stays put and makes everything that comes after it more effective."

    "Once you've used this, you can never go back. [...] I am heavy-handed with this because I can be. It should last you between four and six weeks depending how often you use it, which should be every morning. I travel a lot and when I'm traveling, I treat it like I'm ingesting vitamin C and I use it twice a day. This is my favorite product on the planet. I have six here but I reckon there's more like nine or 10."
