What replaced The Ordinary Buffet Serum?

If you’ve been searching high and low for The Ordinary Buffet Serum, stress not – it hasn’t been discontinued. Say hello to The Ordinary Multi-Peptide + HA Serum, starring the same formula, the same ingredients, and the skin-loving benefits; just with a name that better reflects the magic inside. 

What does The Ordinary Multi-Peptide + HA Serum do?

The Multi-Peptide + HA 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 in the Multi-Peptide + HA Serum?

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 – 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.

What is The Ordinary Multi-Peptide + HA Serum used for?

The Ordinary Multi-Peptide + HA Serum is your go-to if you’re looking to target multiple signs of ageing at once. This powerful formula is packed with peptides, hyaluronic acid, and skin-friendly technologies that help improve the appearance of fine lines, support skin elasticity, and boost overall firmness and smoothness. It’s especially great for anyone starting to notice the early signs of ageing, or those who want to stay ahead of them. 

How to use The Ordinary Multi-Peptide + HA Serum

Using this serum is easy – just follow these steps in your skincare routine:

Step 1: Cleanse your skin as usual.

Step 2: Apply a few drops of the serum to your face and neck, morning and/or evening.

Step 3: Gently pat it in until absorbed.

Step 4: Follow with your favourite moisturiser.

Step 5: In the morning, don’t forget SPF as your final step.

What to use with the Multi-Peptide + HA Serum

To boost the benefits of the Multi-Peptide + HA Serum, pair it with simple, supportive products that hydrate and protect the skin. Start with a gentle, non-stripping cleanser to prep your skin, like The Oridnary’s Squalane Cleanser. Next, layer a hyaluronic acid serum, like The Ordinary Hyaluronic Acid 2% + B5, underneath for extra hydration. After applying the peptide serum, follow with a rich moisturiser to lock everything in and support a healthy skin barrier. Our personal favourite is the Natural Moisturizing Factors + Phytoceramides from The Ordinary, which immediately boosts hydration by 68%. 

What not to use with the Multi-Peptide + HA Serum

Some ingredients don’t play well with peptides and can reduce their effectiveness or increase the risk of irritation. It’s best to avoid using the Multi-Peptide + HA Serum in the same routine as strong actives like vitamin C (ascorbic acid), direct acids (such as glycolic, lactic, or salicylic acid), niacinamide, and retinol. These ingredients can interfere with the serum’s peptide performance or overwhelm the skin when layered together. If you want to use these actives, try alternating them by using your peptide serum in the morning and stronger treatments at night to keep your routine balanced.

Is Multi-Peptide + HA better than retinol?

Not necessarily – they just do different things. Retinol is stronger and works by speeding up cell turnover to reduce wrinkles and improve texture. Multi-Peptide + HA Serum is gentler, focusing on hydration, firmness, and smoothing fine lines. It’s ideal for morning use, especially if you have sensitive skin or want to avoid irritation. Many people use peptides in the morning and retinol at night for a balanced routine.
