This has been a tried and true product for generations. Why? Because Its effective. Estee Lauder consistently put out high quality products but this one really takes the cake. It's a lightweight formula that doesn't leave my oil-prone skin looking like ive stood infront of a deep-fryer all night. Women in your 30's this is a product you should definitely incorporate into your skincare routine. It targets fine lines and early signs of aging. It is easy to use and works well with nearly any skincare product. Its not harsh for those with sensitivity but the results after longterm use are just as good as most chemical peels. It does a great job at brightening dull skin and tightens skin that has begun to lose that elasticity of your youth. It is expensive and the amount of product is on the smaller side but i wouldn't go to bed without it. There are other products out there that might be as effective and perhaps have less of of a strain on your wallet but whether it be because its the solution i grew up with and i dont want to change my ways or because it reigns supreme regardless... I will continue to spend my dollars on the formula i believe to be the reason that i still get carded everywhere i go despite all this grey hair.
