What is a serum?

If you've been wondering for a while what a serum is and why everyone recommends it, here's the clear and direct answer. It's the most concentrated product in your routine, the one with the highest percentage of active ingredients and the one that, when you choose the right one, transforms your skin. Its texture is light, more fluid than a cream, and its main function is to treat specific needs: dehydration, loss of firmness, blemishes, spots, pimples, uneven texture... whatever your skin needs to improve, there's probably a serum that will take care of it.

Unlike other products such as essences or creams, the serum is not designed to moisturise a bit of everything, but to get to the point. That's why it is applied just after the toner and before the cream, acting as that star step that makes the difference. If you want to see real results on your skin, this is the product you can't be without.

What is it used for?

While some products have a more general function (moisturise, protect, etc.), serums are used to treat. Its light texture and high concentration of active ingredients allow it to penetrate into the deeper layers of the skin, where it can really work. And yes, that's also why its effects are felt sooner than those of other products.

A good serum can help you improve the appearance of tone, firm, brighten, soothe, control sebum, fight the signs of aging... and all of these things at once if you choose a well-designed formula. It's like a daily intensive treatment, easy to use and with visible benefits if you apply it consistently.

Main benefits

Provides deep hydration without leaving a greasy feeling.
Visibly improves firmness and elasticity.
Evens skin tone and provides natural radiance.
Strengthens the skin barrier and the skin's protective function.
Reduces the appearance of pores, wrinkles and uneven texture.

A bonus: the serum also improves the efficacy of the products you apply afterwards by preparing the skin and enhancing absorption.

When should serum be applied?

Apply twice a day: morning and evening, right after toner. If you use essence, it would go before the serum, but if you don't, this is your step three. It's a key moment, because it's when your skin is most receptive, especially if the toner has left it slightly damp.

Tip: if you use several serums in the same routine (because yes, you can combine them), start with the wateriest one and finish with the densest. Apply the one that treats your skin's most urgent need first.

How to apply the serum?

Although it is a powerful product, using it well is very simple. The important thing is not to exceed the amount and to apply it carefully.

Steps before applying the serum?

Wash your face properly and pat dry without rubbing.
Apply the toner to balance and lightly moisturise.
Make sure your skin is still a little damp: this makes it easier to absorb.

How to spread it properly?

Place 2 or 3 drops of the serum in the palm of your hand or directly on the face (forehead, cheeks, chin). Spread with your fingertips using gentle pressure, without rubbing. The product is absorbed quickly, so there is no need for a lot of massaging.

How much to apply?

In this case, less is more. Serums are meant to be used in small amounts. If you apply more than necessary, you not only waste product, you can also overload your skin. 3 or 4 drops are usually enough for face and neck.

Extra tip? Wait a few seconds before applying moisturiser so that the serum is well absorbed and you can better seal in the moisture with the next products.
