What is the difference between a serum and an oil?
Serums are targeted skincare products, more often than not, containing highly concentrated ingredients and smaller water-based molecules (meaning they can sink deeper into the skin).
Oils are brilliant all-rounders that simultaneously nourish, protect, and restore. Particularly rich in fatty acids and antioxidants, they act as the skin’s lipid barrier. Like cling wrap. Locking all that moisture in. Whilst providing a quick boost of glow.
Where should I use a serum in my routine?
Serums should always be applied on fresh, clean skin. Slot them into your routine after cleansing and exfoliating, but before your face oils, creams, or SPF.
Where should I use an oil in my routine?
If you’re using a lightweight oil (like Face Hero) it should go after cleansing, exfoliating, serum-ing, and before applying any creams. If you’re using a treatment (dry) oil it goes on after exfoliating or on freshly-cleansed skin. A little higher up in your routine.
Can I use serums and oils together?
Totally. So long as you mean layering your serums and oils. Not mixing them together. Following the cardinal skin rule of thinnest to thickest, serums will always come before oils.
How often should I use serums?
Usage very much depends on the type of serum, the ingredients they contain, and at what concentration. As well as your skin type.
Retinoids, for example, might be best tolerated every other day. Instead of every day. Make sure you’re reading the packaging and following instructions for use. (Consult a derm if still unsure.)
Also: Not all serums are for night and day. Save retinoids, AHAs, BHAs for the evening, and generally speaking, vitamin C performs its best in the morning.
Last hack! Make sure your serums aren’t fighting. That is, don’t layer ingredients that have the potential to impact efficacy. Or more importantly, irritate the skin. More on that here.
