The truth is there isn’t a single best ingredient for skin care. Research has clearly shown that skin needs an abundance of beneficial ingredients, including omega fatty acids, ceramides and peptides (along with many others), as skin is complicated and needs an array of skin-natural ingredients to look young and healthy.

Board-certified dermatologist Dr. Beth McLellan says, “everyone’s skin is different depending on their age, hormonal status, medications, and more and an individualised approach is best.”

We never want you to worry if you’re getting enough of the best ingredients for your skin, which is why we only formulate products that contain a mix of brilliant ingredients. The next step is for you to determine which of these ingredients or mix of ingredients is right for you, but it’s not as difficult as it might seem; in fact, it’s a matter of preference and of experimentation to see which ones perform ideally for the results you want.

When it comes to our products containing omegas, ceramides and peptides, the following is what you need to know to help you decide which ones are right for you. What you’ll notice is that these ingredient groups have some similarities and some significant differences.

Omega fatty acids are superior for:

Omega fatty acids differ from ceramides and peptides because they:

  • Excel at calming skin, including environmentally damaged skin
  • Are excellent for retaining moisture; each omega works individually and as part of a team
  • Do not have a visible firming or skin tone–improving effect

Ceramides are superior for:

Ceramides differ from omega fatty acids and peptides because they:

Peptides are superior for:

Each individual peptide (and there are many) can educate skin to do something distinctive, like improve the appearance of skin tone, firm, diminish the appearance of wrinkles by encouraging layers of skin to act like younger skin and maintaining a smooth, healthy-looking surface.

Peptides differ from omega fatty acids and ceramides because they:

  • Can be engineered to deliver benefits targeted at numerous concerns
  • Can train skin’s surface to look younger in multiple ways (6)
  • Restore proteins, the building blocks of skin
  • Aren’t as hydrating as ceramides or omegas, but work beautifully with those ingredients

Do you need all of them?

Whether or not you need all of these ingredients depends on your skin care needs and concerns, but certainly they are all great to use and can benefit all skin types.

For some skin care needs, if ceramides, peptides and omegas are all found in one product, that’s great. But for advanced concerns, you’ll want products with concentrated ingredient amounts that can be layered with the other products you’re using.

If you have dry, dehydrated skin or if your skin is sensitive or prone to redness, you will see the most benefit by using a mix of products that contain omega fatty acids, ceramides and peptides.

If your skin is combination to oily or blemish-prone, omegas are fine, but you’ll likely derive greater benefits from ceramides to support skin's barrier.

Speaking of signs of ageing, all three groups of ingredients will bring about noticeable improvements in your skin, from enhancing resilience to diminishing the look of lines, wrinkles and uneven texture, and you can begin using them at any age.

According to Dr. McLellan, “achieving a healthy skin barrier is always my first goal. We can’t begin any potentially irritating treatments like retinoids until we address the dryness and irritation.”

Experiment with various products that contain these ingredients, layering them all at once or using them on alternate days. We predict you’ll find that each group’s similarities and differences add up to exponentially better skin!
