What is a Serum?

 

What is a serum - hyaluronic acid serum

 

This website is all about hyaluronic acid serum reviews – so what is hyaluronic acid and what is a serum? Well you can read about hyaluronic acid serum in my post – Hyaluronic acid serum hydrates your skin – but here we will look at serums. 

There are lots of different anti-aging products on the market, each one promising their own solution to younger looking skin. Facial serums or anti-aging serums have become very popular in the last few years, but as with most beauty products there are some many different formulations that selecting just one can be problematical.

That’s why I wrote these hyaluronic acid serum reviews, to help you decide which type and brand of serum is best for your skin. So let’s take a look at serums – just what are they, why are they different to moisturizers and what’s the best way to include a facial serum into your beauty regime?


 

What is a serum?

A serum is a product specially formulated to help specific skin concerns, for example fine line and wrinkles, discolorations, age spots and sagging skin. Compared to the type of moisturizers you may normally use, the molecules in a serum are much smaller, which enables them to penetrate deeper into your skin layers than a regular moisturizer.

Serums are lighter than most moisturizers and more importantly, have a lot more active ingredients, which are delivered deep within your skin to where they can actively improve the condition of your skin.

Serums are not usually oily at all and quickly absorb into your skin, making them a dream under makeup. The texture of a serum is fairly thick, similar to a gel, but not too thick that it cannot be delivered via a dropper – most brands either use a dropper or a pump to deliver the serum.

Each branded serum will have its own list of active ingredients, which the manufacturer believes will best address the problems of aging skin.

The three most common ingredients are hyaluronic acid, vitamin c and retinol (if I haven’t already, I will be writing reviews on retinol serums soon for you). The combination of vitamin c and hyaluronic acid is a powerful one and these two ingredients alone, make it worthwhile including a serum into your beauty regimen.


 

Why use a face serum?

As we age our skin becomes drier, the texture becomes rougher and the amount of collagen in our skin reduces. So over time our skin simply ages and we lose that bright youthful glow to our skin.  We end up with lines and wrinkles, which start off small and fine and then deepen with time, and our skin can become redder with patchy discolorations, and age spots.

Facial serums, depending on the number and type of active ingredients can help diminish and hold off the ravages of time and give us back a more youthful and radiant complexion. Some formulations are also specifically targeted at problem skin with ingredients that reduce the problem of acne in adult skin and the scars that can be so problematical. So serums include ingredients such as antioxidants, skin brighteners and peptides all of which helps to give our skin a healthier glow.

If you have an oily skin, then facial serums are just about perfect for your skin type. They are not oily and absorb quickly into your skin, delivering nourishment deep down where it is needed.


 

Moisturizers vs. face serums

If you are wondering whether you need a moisturizer or a facial serum (most people use both), there are distinct differences between these two beauty products.

So depending on the active ingredients in the serum, a serum can increase the hydration in your skin most certainly, but the main benefit is by delivering lots of fabulous active ingredients into the deeper layers of your skin. These ingredients provide an optimum level of nutrition to your skin helping to give your skin a healthy glow.

The molecules in moisturizers are too big to penetrate your skin so deeply, so even if they have the exact same ingredients as a serum, you will have much more success with a serum than a moisturizer. Your moisturizer is good for hydrating the surface layers of your skin, whereas a serum is good for hydrating mainly the deeper layers with some adding a pulse of moisture to the surface layers as well.

For example, moisturizers with hyaluronic acid will hydrate the top layers of your skin, whereas serums with hyaluronic acid will nourish the deeper layers of your skin.

So a serum with hyaluronic acid is fabulous for delivering a deep pulse of nourishment and hydration to your skin, a serum with vitamin c is great for reversing the signs of aging caused by free radicals – that’s why serums with both hyaluronic acid and vitamin c are the most popular serums.


 

How to use a face serum

Some people can simply apply a facial serum and that’s it – they have no need of a moisturizer to follow the serum. These people usually have oily skin, because if your skin is dry or very dry then just using a serum, even though it delivers oodles of nutrition deep within your skin, the serum can dry out skin that is already too dry.

This is because serums are not a moisturizer in themselves, they just deliver lots of wonderful active ingredients deep within your skin. The surface layers of your skin, if too dry already, may still need the addition of a high quality moisturizer following the serum.

So if you want to include a serum in your daily routine follow these steps:

  1. Cleanse your face and neck areas and pat dry. It is important to just pat your skin, leaving it slightly damp when you apply the serum.
  2. If you normally use a toner, do so now and then apply the serum to your face and neck with your fingertips. You will only need a drop or two to cover the entire area – serums are really good value for money.
  3. Once the serums has absorbed into your skin, apply your favorite moisturizer which helps to lock in the serum and increases its benefits.
  4. Apply your makeup if desired.
