Ingredient Penetration Depths

Understanding how deep skincare ingredients can reach

Stratum Corneum

Outermost protective layer

High MW Hyaluronic Acid

Molecular Size: 1,000-1,800 kDa

Mineral Sunscreens

Molecular Size: Particulate

Silicones

Molecular Size: Film-forming

Ceramides

Molecular Size: 500-1,000 Da

Epidermis

Living skin cells, no blood vessels

Depth: 0.05-0.1mm

Medium MW Hyaluronic Acid

Peptides

Molecular Size: 500-1,500 Da

L-Ascorbic Acid

Molecular Size: 176 Da

Factors Affecting Penetration

Molecular Weight

Smaller molecules (under 500 Da) penetrate deeper. The 500 Da rule states that molecules larger than this rarely penetrate beyond the stratum corneum.

Formulation

Delivery systems like liposomes, nanoparticles, and certain solvents can help larger molecules penetrate deeper into skin layers.

Skin Condition

Damaged or compromised skin barriers allow deeper penetration, while intact barriers are more selective about what passes through.

Frequently Asked Questions

Is Beeswax safe for all skin types?

Beeswax is generally excellent safety profile. It's particularly suitable for dry skin, natural skincare formulations, lip products, balms.

How does Beeswax differ from humectants?

While humectants attract water to the skin, Beeswax is an occlusive that forms a protective barrier on the skin's surface to prevent water loss. It's particularly effective for sealing in moisture after applying hydrating products.

When should I use Beeswax in my routine?

Beeswax works best as one of the final steps in your skincare routine to seal in moisture and other treatments. Apply it after water-based products like serums and moisturizers.

Hyaluronic Acid

Hyaluronic acid is a naturally occurring substance in the human body that has the remarkable ability to hold up to 1,000 times its weight in water. This makes it an exceptional humectant for skincare applications, providing intense hydration and helping to maintain skin plumpness and elasticity.
