Key Studies

The role of ceramides in skin barrier function (2014)

Journal of Clinical and Aesthetic Dermatology

Ceramides comprise 50% of skin lipids. Topical ceramide supplementation restores barrier function and reduces transepidermal water loss in compromised skin.

Ceramide-dominant barrier repair lipids (2019)

Clinical Interventions in Aging

Formulations with a 3:1:1 ratio of ceramides, cholesterol, and fatty acids most effectively mimic the natural skin barrier.

Ceramides in atopic dermatitis (2011)

Journal of the European Academy of Dermatology

Patients with eczema have significantly reduced ceramide levels. Topical ceramide application improves skin hydration and reduces flare frequency.

Frequently Asked Questions

Can I use ceramides every day?

Yes. Ceramides are natural skin components and are safe for daily use, morning and evening. They are non-irritating for all skin types.

Do ceramides clog pores?

No. Ceramides are non-comedogenic and actually help regulate skin barrier function, which can indirectly reduce breakouts.

Should I use ceramides with retinol?

Absolutely. Ceramides help repair the barrier disruption that retinol can cause. Apply retinol first, then a ceramide moisturizer on top.

What is the 3:1:1 ratio?

The optimal ceramide formulation mimics skin lipids: 3 parts ceramides, 1 part cholesterol, 1 part fatty acids. This ratio is most effective for barrier repair.
