HydroPeptide Retinol Routine Booster - 1% Universal Tri-Retinol Complex Peptide Solution for Anti-Aging & Wrinkles (1 oz) - Perfect for Night Skincare Routine & Sensitive Skin Care

HydroPeptide Retinol Routine Booster, 1% Universal Tri-Retinol Complex Peptide Solution, 1 ozThe “Retinol Routine Booster” (I think of it as a serum), arrived in a sealed, branded box which lists the ingredients. The 1 fl oz / 30 ml glass and plastic bottle looked great but is a lot larger than it needs to be for an ounce of product. Once I unscrewed the top I saw the smaller, inside plastic container. The bottle is substantial but easy to hold in the hand. Maybe refills will be sold?The pump worked well for me, no issues. This yellow-colored, unscented booster/serum is a thinner consistency that allows for easier spreading. It applied a bit tacky for me, even with a light layer, but fully absorbed in about 5 minutes with just the slightest tackiness if I really looked for it.The “1% Tri-Retinol Complex” (retinol, retinyl linoleate, and glyceryl diretinoate) was apparent to me as this booster/serum felt strong on my skin (and my neck was irritated, see below). However, this isn’t just a retinol, there are a lot of other great ingredients (and no “icky” ones): niacinamide, glycerin, Vitamin C, sodium hyaluronate, hyaluronic acid, allantoin, bisabolol, hydroxyphenoxy propionic acid, green tea, and myristooyl pentapetide-16. Since it’s summer I either applied a very light moisturizer after this or none at all. As recommended, I wear SPF 30 every day (in a light moisturizer) on my face and neck.I’ve been using retinol products for years on my face, so I didn’t experience any irritation using this booster/serum every two or three days (with a lighter retinol in between). My face loved this retinol (I have acne-prone, combination skin), and the fine lines around my eye area showed a bit of improvement (!) over the little over two weeks I’ve been using this.However, my neck is more sensitive, and I experienced redness and irritation after a few uses. I’ve taken a week off and will start using this just once a week on my neck.Vegan and Cruelty Free per the brand’s website and the Amazon listing, but not listed on the box or bottle. The box and bottle I received in July 2023 were both marked “EXP 02/2026”. An icon states the product is good for 12 months after opening. Made in the U.S.A.
