If you are looking for products that don't cause acne, then please see the section on acne below. How do I know what to use in my skincare routine to make the skin healthier? It's simple, just ask me how I feel about my skincare routine and I'll tell you the best thing to do in my opinion. For example, I am the person who hates skincare that contains acids, which are harsh exfoliants. I believe there are many products that are helpful against acne, but if you want to avoid the chemicals that cause acne, you should look for products that are mild enough that your skin can tolerate them. This is why I usually advise people to try to avoid chemical exfoliants when possible. What should I use? If you're already using an anti-aging serum, then you can also apply it directly to the skin. This way you don't have to use it twice, just once. Do I need to moisturize the skin before using this serum? No. This serum is moisturizing because it contains a glycolic acid, which helps to improve the elasticity of the skin. What kind of ingredients is this serum made from? The serum is made from glycolic acid, which has anti-oxidant properties. It also has an anti-aging effect. Does the serum contain benzoyl peroxide? Yes.
