At other times, when your skin is dry or the environment is drying, you will find that you need both a serum and a moisturizer.
Serums are thinner and lighter than moisturizers and have a greater variety of functions. So actually, the biggest difference between a serum and a moisturizer is what the serum does NOT include. Serums leave out the occlusive moisturizing ingredients such as petrolatum or mineral oil that keep water from evaporating. They also contain fewer lubricating and thickening agents, like nut or seed oils.
In fact, most serums are water-based, eliminating oils completely. Because they leave out these moisturizing agents, serums are left with a high concentration of active ingredients. Serums often contain the strongest dose of ingredients — like antioxidants, peptides, and skin brighteners — that you can find in nonprescription products.
Because active ingredients are more expensive than thickeners, serums can also be more costly. But when applied properly, a 1-ounce container of serum should last you months, and many serums have applicators to dispense just the tiny amount you need. Since serums contain the active ingredients that you want to penetrate as deeply as possible into your skin, you should always apply a serum directly to your skin after cleansing or toning and before your moisturizer and sunscreen.
Serums, on the other hand, are formulated to penetrate deeply into the skin and address or even reverse the causes of ageing and skin damage at the cellular level. Serums are likely to contain more antioxidants, nutrients and vitamins that work to repair the structure of skin cells, increasing skin radiance, smoothness and suppleness. So let's break down the difference between serum and moisturizer.
A big difference between serums and moisturizers is what serums don't include. Serums also contain fewer fillers, thickeners and lubricating agents. The second important difference is that serums are actually able to work more effectively in your skin for two reasons. Firstly, because serums have smaller particles they penetrate the skin on a deeper cellular level. Serums are lightweight, intensive skin care products formulated to penetrate deeply, allowing their active ingredients to combat free radical damage, skin pigmentation, ageing, acne and scarring by delivering nutrients and vitamins right into the skin cells.
Serums providing antioxidants, peptides, hyaluronic acid and Vitamin C can have dramatic and swift effects on the radiance of skin by brightening, exfoliating and hydrating the skin.
Serums are designed to repair the skin at a cellular level and act on a wide range of skin health factors at the same time. If you have aged, damaged, scarred or sun damaged skin, a serum is your best choice to reduce the visible impacts on your skin. Serums act to improve skin firmness, smoothness and luminosity while reducing fine lines and wrinkles. A moisturizer is a lotion or cream which contains skin hydrating emollients and forms a physical barrier to help skin stay hydrated.
Their main benefit is that they seal the skin, locking in moisture and nutrients. The thicker, heavier ingredients in moisturizing creams form a barrier on your skin designed to lock in moisture in. But it can also lock active ingredients in the moisturizer out of the skin, reducing their efficacy. This is where the layering effect comes into play — while an antioxidant serum works to repair skin cells and combat free radicals, a moisturizer acts to prevent the evaporation of moisture and provides a physical barrier to protect the skin from environmental irritants and makeup particles.
Serums can be used both morning and night to address specific skin issues more effectively than a moisturizer alone, and will also boost the hydrating effects of your moisturizer. Ensure your serum contains antioxidants to provide protection from environmental damage. Also, while some serums contain hydrating ingredients such as hyaluronic acid, you need to layer a moisturizer over the serum to seal it into the skin.
