Absolutely love these serums and would recommend to anyone who is looking to adds 3 basic but important serums into their routine! The Hyaluronic Acid does a great job of hydrating the skin and I love how the formula is not watery but the perfect consistency. I enjoyed the immediate brightening of my skin with the Vitamin C where my tone appears brighter and warmer after application. The Retinoid is amazing with smoothening the skin and really making it plump and full of life (youthful). I don't think anyone would regret purchasing these products. Definitely worth your money!
