Do We Really Need Face Serum?

The beauty industry has come out with so many different products which can get confusing when you are trying to purchase a skincare product and end up with toner, lotion, moisturizer, serum, ampoule, eye cream, oil, etc to choose from. A question that immediately hits my mind is that do we really need all of them? Is it worth buying all different products? More specifically,
if I am using a toner and a moisturizer, do I need a serum? 
A serum comes with many different skin care benefits, from clearing blemishes to lifting sagging skin. It is a light version of moisturizer that can penetrate deeper down in your skin to deliver active ingredients. Leaving out the heavier ingredients, face serum has a higher proportion of active ingredients. Therefore, it is recommended to use it with a heavier moisturizer since serum will only moisturize to a minimal extent.
A serum isn't necessary to have in your skincare regimen. Even though it is an added step, it definitely gives your the better condition. The better condition your skin is in, the more flawless looking your makeup looks and wears throughout the day. 
The most common misconception about serum is that consumers think that more is better. However, because serums are typically very concentrated with active ingredients, a little goes a long way.
The price of serum can easily break our wallets; so always look at the ingredients to ensure both that the serum addresses your skin concerns and includes ingredients that make skin healthy. I would like to recommend using a serum sheet mask for anyone who is interested. It is a more affordable way of getting what your skin wants.
