Ingredients Explained

Emollient, Skin Conditioning

Jojoba oil is one of the most well-studied plant-derived ingredients in cosmetics. It is an emollient with a special structure.

Because it is made up of 97-98% wax esters, it closely mirrors the linear monoesters found in human sebum. This makes it skin compatible, non-greasy, and lightweight.

Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture.

Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%).

Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing.

Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.

Due to its fatty acid content, Jojoba oil may not be fungal acne safe.

Emollient, Skin Conditioning, Solvent

This ingredient is a small silicone made to be silky and weightless. It works as an emollient and solvent for heavier pigments/silicones as well.

According to the CIR Expert Panel, this ingredient is considered gentle and doesn't penetrate deeply into skin.

The EU and UK have banned this ingredient in cosmetics since 2020. A separate EU REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) rule caps D4 as a trace impurity at under 0.1% in any cosmetic.

In September of 2025, the US EPA's draft TSCA risk evaluation that came out in September 2025 preliminarily found D4 poses "unreasonable risk to human health and the environment". This could lead to restrictions in the next year or so.

Humectant, Skin Conditioning

Hydrolyzed Keratin is derived from keratin. Keratin is a large protein that is naturally found in our hair and skin.

Studies show keratin is able to seal broken hair cuticles, helping to prevent split ends and breakage.

As a humectant, hydrolyzed keratin helps draw moisture from the air to your hair and skin. This helps keep your skin and hair hydrated.

Emollient, Skin Conditioning

Rosehip Oil is a non-fragrant plant oil. Rosehips are a fruit from a rose bush and are edible. This oil has skin conditioning and hydrating properties.

Rosehip contains Vitamin C, Vitamin E, fatty acids and linolenic acids. These nourish your skin barrier. Having hydrated skin may help reduce the appearance of fine-lines and wrinkles.

Another great component of Rosehip Oil is Vitamin A, or retinol. Vitamin A encourages your skin to create more collagen.

Rosehip oil may help with reducing pigmentation. The lycopene and beta-carotene have skin-lightening properties. However, more studies are needed to confirm this.

Antioxidant, Skin Conditioning

Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.

One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.

Tocopheryl Acetate is commonly found in both skincare and dietary supplements.
