Medik8 Crystal Retinal 3 - Brightening, Firming, Advanced Skin Regenerating Retinaldehyde Serum - Smoothing, Hydrating Wrinkle Repair Recipe - With Hyaluronic Acid, Glycerin, and Vitamin E - 1 oz

This product is truly a 10/10 for me. The quality, texture, and formulation feel very premium, and I love that it uses retinaldehyde instead of traditional retinol. It feels effective while still being comfortable on my skin and has become one of my favorite nighttime skincare products. The price is higher, but the quality of the formula makes it feel worth the investment.

El producto es excelente pero el empaque llegó mal y parece que no traía todo el producto.

Excellent !

I’ve used Medik8 Crystal Retinal for quite a while, purchasing it directly from Medik8’s website. This is my first time buying it on Amazon because of the great Prime Day price. As someone in my mid-50s, I use several anti-aging products, including prescription tretinoin, and Crystal Retinal has become one of the products I reach for most often. It’s gentle enough to use consistently without the irritation that stronger retinoids can sometimes cause. The attached photo shows my current skin with no filter or editing. The texture is lightweight, absorbs quickly, and layers well with moisturizer. It leaves my skin feeling smooth and comfortable, making it an easy choice on nights when I don’t want to use tretinoin. If you’re new to retinal or have sensitive skin, Strength 3 is an excellent place to start. More experienced retinoid users may eventually want to move up to a higher strength. The only downside is the regular retail price, so I usually wait until it’s on sale before buying another one.
