Comparison between Murad Rapid Dark Spot Correcting Serum vs. Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant - Trial Size

Glycolic Acid is the most researched AHA with proven efficiency and it’s a super powerful component. It’s a great exfoliator, meaning it helps to remove dead skin cells preventing bacterial growth, and make your skin look fresh and smooth. It helps to remove dark spots and areas, making skin tone even. But the most serious reason for using this component is that it helps to produce collagen, which is very important for keeping your skin healthy. This is what makes Glycolic Acid so special. Pay attention, that using any AHA makes your skin more UV sensitive. It’s very important to use good sunscreen after applying AHA.

Water is a great solvent. It’s neutral and doesn’t provide any strong positive or negative effects. It just helps components to mix better and to transport active components.

Alcohol Denatured is a great bacteria killer. Manufacturers often put it inside products to increase their shelf life.

It’s one of the most harmful alcohols used in skincare. You should use it carefully, especially if you have dry skin. It removes oily barrier from the surface of your skin making it less protected and causing dryness. We advise you to pay attention to the position of this component in a formulation. If it stays below the 6th position it will hardly harm your skin. We also recommend testing the product first before application. If you feel a “cooling effect” it means the product contains a lot of alcohol and it's better to be careful with it.
