Ceramides vs. Peptides: Which Skin Care Ingredient Is ...

With so many skin care ingredients in the market, it’s easy to feel overwhelmed. Ceramides and peptides often appear in products promising firmer, bouncier-looking skin, but do you know how they actually work? Although both support healthy skin, ceramides and peptides are completely different ingredients with distinct roles in skin care.

The good news is that ceramides and peptides are both well-researched ingredients that make great additions to your routine. That said, a better understanding of what each one does can help you choose products that match your specific skin needs. Keep reading to find out how they work and learn which active suits your skin!

What Are the Differences between Ceramides and Peptides?

Here’s a crash course on the basic differences between ceramides and peptides to help you pick your next skin savior.

	Ceramides	Peptides
What is it?	Waxy lipid molecules composed of fatty acids and sphingosine.	Short-chains of amino acids, which are building blocks of proteins.
Where can it be found in the body?	Makes up about 50% of lipids in skin’s stratum corneum (the outer layer), also known as the skin barrier.	Found throughout the body as messengers between cells, contributing to functions like hormone regulation, collagen and elastin production and skin repair.
What does it do?	Barrier support. Ceramide skin care softens skin and repairs a damaged skin barrier to help retain moisture and protect skin against external aggressors.	Anti-aging support. Peptides support collagen production to improve skin elasticity for a firmer, more youthful appearance.
What skin types should use it?	Dry skin, sensitive and eczema-prone skin would benefit most from barrier-supporting ceramides.	Mature skin and skin with fine lines and signs of premature aging would benefit most from elasticity-supporting peptides.
How do I spot it in ingredient lists?	Common ceramides in skin care include ceramide NP, ceramide AP, ceramide EOP, ceramide NS and ceramide EOS.	Common peptides in skin care include palmitoyl hexapeptide-19 and copper tripeptide-1.

Can I Use Ceramides and Peptides Together?

In short, yes! Ceramides and peptides are excellent for your skin as individual ingredients, and some formulas combine the anti-aging prowess of peptides with the barrier-repairing power of ceramides for softer and more lifted skin.

If you have two different products containing each ingredient, it’s a good idea to use the peptide product before layering the ceramide product on top. The ceramide product will be thicker in texture and form a protective layer to help active ingredients absorb more effectively and seal in hydration.

Start off with a peptide serum or ampoule to boost collagen synthesis and skin elasticity.

Finish your routine with a rich ceramide moisturizer to lock it all in. Ceramide is one of the most commonly found ingredients in the best skin barrier-repairing products, so you’ll be sure to achieve a nourished and healthy moisture barrier with these in tow.
