If you already use a moisturiser or a facial oil, you may wonder how a serum can fit into your beauty regime.
With so many products delivering different results it can be hard to know what is right for your skin.
In this article we’ll be looking at when to use serum on your face, why serums are so beneficial for your skin and give our editor’s recommendations for the best organic facial serums for morning and evening skin care routines.
At a glance:
- A facial serum is a water-based skin care product that delivers a concentrated dose of nourishment and hydration
- You should apply a serum after cleansing but before your moisturiser or facial oil
- Best serum for morning: Age Defy+ Collagen Boost Vitamin C Serum
- Best serum for evening: Age Defy+ Retinal Booster Serum
- Best serum for sensitive skin: Scent Free Hyaluronic Booster Serum
What is a facial serum?
Serums are traditionally water-based skin care products that are infused with vitamin-rich oils, minerals and antioxidants.
Their ultra-lightweight formula makes them perfect for layering, as they won’t leave your skin feeling weighed down or congested.
They help to lock in moisture, reduce wrinkles and tone the skin, as well as helping to reduce inflammation caused by acne and other skin conditions.
What does serum do?
Serums contain higher levels of moisture-based active ingredients than face creams and lotions, so they are typically able to penetrate deeper into the skin than a moisturiser.
Because of this, they can deliver a concentrated dose of nourishment and hydration, targeting specific skin concerns such as wrinkles, dryness and inflammation, which often start in the deeper layers of living skin tissue.
When to apply serum?
A serum should be applied after cleansing and before your moisturiser or facial oil.

Moisturisers and facial oils create a protective barrier on top of the skin to prevent moisture loss and to protect your skin from external aggressors such as pollution and free radicals.
If you apply your serum after either of these types of products it would sit on top of your skin and be partly wasted.
Natural and organic serums
Green People’s organic serums deliver so much more than simple hydration. Based on organic Aloe Vera, each serum is soothing and balancing for sensitive skin and rich in restorative, rejuvenating plant actives.
Ingredients such as Everlasting Flower and Seaweed are packed with protective antioxidants that help to prevent premature skin ageing, while Jojoba and Pomegranate oils deliver intense nourishment.
