Our hydration secret: The science behind ultimate skin moisturisation

At the end of the day, when all is said and done, any moisturiser needs to moisturise.

The term is often thrown around quite loosely and seems to mean “a cream you put on your face” but outside of protecting and repairing your skin, we see genuine moisturisation of your skin as a key technological objective. Many products promise moisture but fail to keep it locked in.

At LifeJacket, we believe in science-backed skincare that actually works. That’s why our Daily Repair Moisturiser contains a key ingredient you might not have heard of—but definitely need: Cetearyl Nonanoate.

This powerful emollient doesn’t just hydrate—it improves skin barrier function, prevents moisture loss, and enhances the absorption of other beneficial ingredients. Here’s how it works, backed by science.

Why skin hydration matters

Your skin is your body’s first line of defense. It protects you from pollution, bacteria, UV radiation, and harsh weather. But when it’s dehydrated, that barrier weakens—leading to dryness, irritation, and premature aging.

Well-hydrated skin is:

✅ More resilient against environmental damage
✅ Smoother and more elastic (bye-bye, fine lines!)
✅ Less prone to irritation and redness

But hydration isn’t just about drinking water. Your skin needs external moisture-retaining ingredients to stay full and healthy—which is where Cetearyl Nonanoate comes in.

What is Cetearyl Nonanoate and why does it matter?

Cetearyl Nonanoate is a lightweight emollient derived from cetearyl alcohol and nonanoic acid. It’s often used in high-performance skincare because it:

🔬 Locks in moisture without clogging pores
🔬 Creates a protective barrier to prevent water loss
🔬 Gives skincare products a silky, non-greasy feel

Unlike heavy occlusives (like petroleum jelly) that sit on top of your skin, Cetearyl Nonanoate absorbs quickly, making your moisturizer more effective without leaving an oily residue.

Scientific evidence

A 2021 study published in the International Journal of Cosmetic Science found that esters like Cetearyl Nonanoate improve skin hydration by reinforcing the skin’s natural lipid barrier, helping to prevent transepidermal water loss (TEWL).

Another study in Cosmetic Dermatology highlighted that esters not only enhance skin feel but also improve the penetration of active ingredients, making your entire skincare routine more effective.

How Cetearyl Nonanoate transforms your skin

So, what does this mean for you?

When used in our Daily Repair Moisturiser, Cetearyl Nonanoate ensures that:

🌟 Your skin stays hydrated all day (no more tight, flaky skin by lunchtime)
🌟 You get deep hydration without the greasy feel
🌟 Other active ingredients—like antioxidants and skin-repairing agents—penetrate more effectively

The result? Softer, healthier, and more resilient skin—even in harsh weather conditions.
