A Deep Dive Into Our Carrier Oils

A Deep Dive Into Our Carrier Oils

When I first start to formulate a new product, I don't just begin with the trendy ingredient. I also start with the base.

The carrier oils are the foundation of our serum and elixir formulas. They determine how nutrients travel, and how deeply they penetrate into the skin. How the formula as a whole interacts with your skin’s barrier, and whether a formula feels balancing, stimulating, weightless, or deeply restorative.

Every carrier oil in our line was chosen with intention. Not because it looks or smells beautiful (although that's always a plus), but because it behaves beautifully.

You can't just add beautiful botanicals or the latest actives to any oil. If the base oil is wrong, the formula cannot perform optimally. Carrier oils determine:

  1. Absorption speed
  2. Barrier compatibility
  3. Oxidative stability
  4. Nutrient delivery
  5. Long-term skin response
Happy Hour Balancing Serum
Why Grapeseed Oil

Happy Hour is a calming serum, so the base oil needed to act as a delivery system for the ingredients in the formula that soothe, calm, and reduce redness. The foundation needed to be intelligent, lightweight, and universally compatible.

Grapeseed oil is high in linoleic acid, an essential fatty acid that acne-prone and inflamed skin is often deficient in. It is fast absorbing, low on the comedogenic scale, and exceptionally receptive to active botanicals. It carries the azulenes from blue tansy, the bisabolol from chamomile, and the soothing compounds in lavender directly into the upper layers of the skin without creating heaviness.

It strengthens the barrier while allowing the skin to breathe.

This is why Happy Hour feels balancing instead of oily. It calms without coating.


Siren Serum
Why Jojoba Oil

Jojoba oil is not technically an oil. It is a liquid wax ester, and structurally, it closely resembles human sebum. That similarity changes everything.

Because skin recognizes jojoba as familiar, it integrates into the lipid matrix easily. It helps regulate oil flow rather than suppressing it. It stabilizes the skin while allowing more stimulating botanicals to work intelligently.

Siren contains circulation-supporting ingredients. I needed a base that would prevent overstimulation and maintain barrier harmony.

Jojoba does exactly that. It is remarkably stable, resistant to oxidation, and supportive for both oily and congested skin.

It does not force the skin to behave differently. It teaches it how to function better.

Aloha Ambrosia Elixir
Why Olive-Derived Squalane

Aloha is our morning moisturizer, so I wanted it to disappear into the skin, allowing for the easy application of makeup and SPF.

Olive-derived squalane is a hydrogenated form of squalene, a lipid your skin naturally produces. Because it is biomimetic, it integrates seamlessly into the barrier.

It fills microscopic cracks between skin cells. It reduces transepidermal water loss. It smooths texture. It enhances light reflection.

This is why Aloha works beautifully under makeup. It behaves like a dry emollient, creating slip without shine. It also improves antioxidant transport and helps even the appearance of tone over time by reducing oxidative stress.

Weightless. Intelligent. Protective.

Mahina Elixir
Why Moringa and Marula

Mahina is our nighttime moisturizer, but I formulated it to also be deeply restorative.

At night, skin shifts into repair mode. Lipid synthesis increases. Cellular turnover accelerates. This is when richer oils make sense.

Moringa oil is high in oleic acid and behenic acid, and is deeply nourishing and barrier supportive. Marula oil provides a powerful antioxidant profile with tocopherols and polyphenols.

Together they create a lipid environment capable of dissolving and activating Coenzyme Q10, a fat-soluble antioxidant that supports mitochondrial energy in skin cells.

CoQ10 cannot function effectively in water, it requires lipid transport. Moringa and marula solubilize CoQ10, protect it from oxidation, and deliver it into the skin’s lipid layers.

Mahina is not simply moisturizing. It is rebuilding.
