I want to preface this by saying that I do not have wrinkles or saggy/crepey skin on my neck, so I cannot speak to the product’s efficacy regarding wrinkles reduction. However, I do my best to take care of the skin on my neck and love this product for its moisturizing benefits. I like to wear this while reading before bed. Frownies offers a lot of information on the website write-up, but the packaging doesn’t include that it’s meant to adhere to the skin (which seems to be the main complaint from customers). Like the eye gels, you have to recline in order to use it. And even then, it’s super slippery the first few times of wear. So there’s a lot of repositioning. It’s probably not possible, but if there was a way to add a strap or something, that would make it a little easier to use. If you could combine the chin-up and the serum patch somehow, haha. But my skin is always super moisturized after use, and I can get around 5-6 uses out of one patch. Definitely recommend 👍🏽
