What is a serum and do you need one?

Serums are lightweight skincare formulas designed to deliver a high concentration of active ingredients directly onto skin. Whether formulated with a potent amount of one ingredient or a blend of multiple key ingredients, serums boost your results by targeting a particular skin concern such as signs of ageing, dehydration, imperfections or dullness. While a serum is not always necessary, they can elevate your routine and help you see results from your skincare faster.



Do you need a serum and a moisturiser?

Do you need a serum and a moisturiser?

The benefits of serums and moisturisers often overlap, which may have you questioning if you need to use both. The answer in a nutshell? Serums are optional, but moisturisers are essential. You can use a moisturiser without a serum, but not a serum without a moisturiser, or you can use both. Why? Because the main purpose of moisturiser will always be to hydrate skin, and daily hydration is essential to keep skin soft, smooth and healthy-looking. Serums often hydrate skin too, but they are much more lightweight and are intended to be used alongside your moisturiser, not as a replacement.

So, when should you use a serum and a moisturiser? If you have a particular skin concern or if you would like to see faster results from your routine. It also comes down to personal preference. You may find that you enjoy the results that come with using a serum, or you could find that you prefer the simplicity of a three-step routine.

Where does a serum sit in your routine?

Decided that you want to use a serum? Now let’s cover how to add it to your routine. Apply your serum after cleansing and toning, but before your moisturiser. If you are using multiple serums, or an eye cream, apply your products in order of thinnest to thickest texture and finish with your moisturiser in the evening and SPF in the daytime. Serums can be applied as part of your morning or evening routine or both, it’s up to you.

Using multiple serums? You could layer them at the same time, apply one in the morning and one in the evening, or on different days. It is worth experimenting to see what works best for your skin.
