8 Things You Need To Know About The Ordinary Buffet Serum

From what’s inside to how to use it, scroll down to learn everything you need to know about Buffet, one of The Ordinary’s most popular skin serums. 

What does Buffet do? 

Buffet is a multitasking water-based serum which cleverly targets multiple signs of skin ageing and improves overall skin health. It helps to reduce fine lines and wrinkles, boost hydration, fade pigmentation, brighten dull skin, and firm and smooth skin texture. 


What’s inside Buffet? 

Peptides – Peptides are the proteins and molecules that make up the building blocks of skin, and keep it feeling smooth, firm, and bouncy. They send signals to cells which encourages them to produce more collagen (which our bodies loose as we age). 

Matrixyl – Matrixyl is a powerful peptide blend which is formulated to have really long-lasting results. It specifically targets collagen production and repairs damage. 

Probiotics – Prebiotics are a food source for probiotics (‘good’ bacteria). By feeding and increasing the amount of probiotics, they lead to a stronger skin barrier and improved moisture retention. 

Amino acids – Amino acids work to strengthen skin, maintain hydration levels, improve resilience, and contribute to an overall healthy appearance. They also protect skin from free-radical damage that can lead to signs of ageing. 

Hyaluronic acid – Hyaluronic acid acts like a magnet to draw moisture into the skin. Each molecule can hold up to 1000 times its weight in water, so it massively improves skin’s hydration levels. 


How do you use Buffet? 

Apply to the face in the AM and/or PM after cleansing and before moisturising. Press into skin, rather than wiping over, to improve absorption. 


Who should use Buffet? 

Anyone looking to improve their overall skin health can benefit from using Buffet (and it’s great for all skintypes), but it’s particularly beneficial to those looking to target signs of skin ageing.


Why is it called Buffet? 

The name of this product is inspired by the concept of a food buffet. Unlike most of The Ordinary’s single ingredient formulas, this one contains a large combination of multiple ingredients. 


What ingredients can I use with Buffet? 

Since the formula already contains multiple ingredients, you don’t really need to layer other serums with it, and there are certain combinations that should be avoided (see below). However, it’s totally safe to apply Buffet in the same routine as hyaluronic acid. 


What ingredients shouldn’t be combined with Buffet? 

It’s recommended not to combine these ingredients with The Ordinary Buffet in the same routine because they can compromise the performance of the peptides, and in some cases could cause skin irritation.  

Vitamin C 

Direct acids (e.g. glycolic, lactic, salicylic) 




What pH is Buffet? 

The pH of Buffet sits at 4.5-5.5, towards the acidic end of the pH scale.
