Serum vs Moisturiser - What's the Difference? And do Men Need Both?
You've got you cleanser and moisturiser and then someone starts mentioning serums and suddenly your bathroom shelf feels like a chemistry exam.
Here's the short version, a serum treats, a moisturiser protects. One targets a specific skin concern and the other keeps your skin hydrated, comfortable and defended. They do different jobs which is why they are not interchangeable.
Lets break it down.
What is a serum? Shop Serums
A serum is a lightweight fast absorbing treatment packed with high concentration of active ingredients. Think of it as the specialist in your routine. Generally the formula is thin and the molecules are small, a serum can deliver its actives deeper into the skin than a thicker cream can. You only need a few drops.
What serums are good for;
- Fine lines and early signs of ageing (retinols, peptides)
- Dullness and uneven skin tone (vitamin c)
- Oiliness, enlarged looking pores, congestion (salicylic acid, niacinamide)
- Deep hydration (hyaluronic acid)
If you have a specific skin goal a serum is how you can make it happen. Check out our blog on skin types and skin concern to determine what you need.
What is a moisturiser? Shop Moisturisers
A moisturiser is the all-rounder. It's job is to hydrate the skin, lock that hydration in and support your skin barrier. Also keeps irritants out.
Most moisturisers combine three types of ingredients. Humectants (like glycerin) which draw water into the skin, Emollients (like ceramides) which smooth and soften and Occlusives (like Squalane or shea butter) seal everything in. What a serum targets a moisturiser supports. It's the step that leaves your skin feeling comfortable rather than tight, especially after shaving, a hot shower or a day in dry air-conditioning.
Can a serum replace a moisturiser?
Generally no, most serums are not designed to seal in moisture or reinforce the skin barrier. Skipping moisturiser after a serum, particularly one with active ingredients like retinol or vitamin c, can leave your skin feeling dry, tight or irritated.
It works the other way too, a moisturiser wont give you the concentrated results a targeted serum can.
How to use them together
When it comes to skincare you always want to be applying the thinnest to the thickest.
