Before we answer that, there’s another question we encourage you to ask yourself and it’s a very simple one: 

 

What is it you want most from your skincare?

 

There are so many reasons people use skincare products, whether those products are off the shelf, or natural formulations they’ve made themselves.

You might want products to clean or brighten your skin, or to help you with skin that’s sensitive, oily or dry. Maybe you hope to improve a skin condition, heal or rejuvenate damaged skin, or reduce the signs of aging.

Why are serums good for your skin (and what are their benefits)? Skincare Formulation

Whatever the answer, there’s one thing we think everybody wants. 

 

It’s simply that wonderful feeling of inner confidence that comes when your skin looks and feels its radiant best. 

And serums are those star skincare products that have the most effective ingredients, formulated to make a difference that you can see and feel. 

So what exactly is a serum, anyway?

There are hundreds of products out there that are marketed as serums… and it’s no wonder. Serums are packed full of specialist ingredients that are targeted to specifically deliver visible and long lasting results and benefits.

 

Why are serums good for your skin (and what are their benefits)? Skincare Formulation

That’s why they’re usually the most expensive skincare product on anyone’s shelf. So they’re not just good for your skin, they’re good for beauty brands who sell serums as a premium product.  

 

But not all serums are the same. 

 

In fact, there are at least six very different types of formulations that you can find labelled as serums – anhydrous serums, pressed serums, gel-based serums, emulsion-based serums, gel-cream serums and bi-phase serums. 

If you want to find out more, you can read our article on the six different types of serums and their benefits here:

In addition to these six different types of serums, there are serums which are made to target specific areas of the body, eg face, eyes, lips, neck, body and hair.

So although lots of people might think of serums as just nice face oils, as you can see there’s really a lot more to them than meets the eye! 

Can a facial oil offer the same benefits as a serum?

There are some products sold as serums that are, in fact, facial oils. 

 

Now, there is nothing at all wrong with facial oils – they are amongst our favourite recipes! Facial oils that have top quality ingredients, like essential oils or the more specialist carrier oils, can be very effective at nourishing the skin, improving the tone and complexion and giving a silky soft feeling.

But these more simple facial oils don’t have the same potential compared to the high-performance serums that are now available. There are some things that oil-based products like these simply cannot do – and that’s where the more complex high-performance serums with their high-performance botanical extracts, come into their own.

Moisturizing is not hydrating

The oils we use for natural skincare products have many benefits and can be excellent at moisturizing the skin. 

 

Different types of oils can moisturize the skin in different ways. 

 

All of the oil soluble ingredients, eg carrier oils, essential oils, butters and waxes help to replenish the lipid (oil) barrier between the cells of our skin and this helps to improve the silky, soft and moisturized skin feel. 

 

These oil soluble ingredients are known as ‘emollients’ which is a quality that softens and smooths the skin.

 

In addition to that, some of these oil soluble ingredients, eg butters and waxes and the thicker carrier oils, are occlusive, which means they prevent transepidermal water loss (the loss of moisture from the skin) by covering the skin in a protective layer.

So, to conclude about the benefits of these oil soluble ingredients, they are emollients and occlusives which offer great moisturizing qualities.

But there is one thing oil-based products can’t do… and that’s hydrate your skin.

 

To hydrate your skin you need water and water soluble ingredients. 

 

Anhydrous (or oil-based) serums can’t do that.

Oil and water don’t naturally mix. Ingredients that dissolve in water won’t dissolve in oil, and those that dissolve in oil, simply won’t dissolve in water.

Why are serums good for your skin (and what are their benefits)? Skincare Formulation

For this reason, products that are made only from oils and ingredients that dissolve in oil are called anhydrous, which means “without water”. 

 To hydrate your skin, on the other hand, means adding water – and so products that can hydrate must be water-based or contain water such as emulsions (a blend of oil and water with an emulsifying agent).

 To formulate a product that can both moisturize and hydrate your skin, you need to create something that can harness the best of both oil and water soluble ingredients. 

And that’s one reason why high-performance serums are more complex to formulate.

 

To make a product that includes both oil and water soluble ingredients, you will need to create an emulsion. And a product that contains water soluble ingredients must include a preservative – without these, the product will not be safe or stable. 

You’ll probably also need the addition of thickeners to get the right texture for the product you need. A cream tends to be thicker than a lotion, for example.

But the real challenge of formulating serums is learning to work with the specialist ingredients. 

What makes a serum high-performance? 

Serums are high-performance because they are made from high-performance ingredients, such as vitamins and their derivatives, peptides and ceramides.

We’re talking about active ingredients that are toning, anti-inflammatory, anti-aging, antimicrobial, skin brightening, skin barrier repairing, strengthening and provides sun protection. 

 

And formulating with these high performance ingredients can be very tricky. 

 

They all have very specific individual requirements, plus these specific requirements can change when different specialist ingredients are used together. If you don’t know what these requirements are your product will fail, and you won’t know why.

Some of the most powerful botanical extracts you’ll find in a serum, those star ingredients that can make a real difference to your skin, need very careful handling.

They might spoil if stored or handled at the wrong temperature, or simply not work if combined with certain other ingredients. Some are very quick to oxidize, while others are only effective in solutions with the correct pH (the measure of how acidic or alkaline a solution is).

One ingredient that has wonderful benefits for your skin is Vitamin C, but it is volatile to work with, and requires careful handling. If you want to find out more, download our free guide to working with Vitamin C 

Creating your own natural serums

It’s true. Even though they’re more complex to formulate, and high-performance serums are not the type of cosmetics that can easily be perfected through trial and error, with the right training you can make these amazing premium products. 

 

Creating a successful serum takes time, patience and practice – but you can do it. 

 

Whilst nothing is a substitute for joining one of our online courses and investing your time and energy into learning the right way to do things, our article How You Can Make a Natural Face Serum… that Actually Works will offer some additional information that you may find useful.

Even if you have experience in making your own natural skincare products, serums can be a challenge. But even though they are amongst the most complex cosmetic formulations you can find, you can learn to create serums that do everything a store-bought product with a premium price tag can do.

Why are serums good for your skin (and what are their benefits)? Skincare Formulation

In fact, you can create serums that do more than that… you can make a high-quality serum that does exactly what you want it to.

You can choose to make serums that are organic, or vegan, or that don’t use laboratory-created chemicals, or that champion recycled packaging, or that support communities or environmentally conscious suppliers. 

 

You can make a high-end product that fits with your principles or values.
