Transungual Biophysics

How Botanical Oils Penetrate Dense Keratin

The human nail plate is composed of 25–30 layers of hardened onychocytes. Unlike synthetic lacquers that trap moisture on the surface, natural wax esters naturally diffuse through the intercellular lipid network.

1

Surface Wetting

The precision silicone brush dispenses micro-droplets with ultra-low surface tension that spread evenly across micro-ridges and lateral folds.

2

Lipid Navigation

Jojoba and Meadowfoam wax esters match human sebum, transporting Terpinen-4-ol through microscopic keratin pores.

3

Subungual Action

Active botanical terpenes and polyphenols neutralize microbial biofilms in the dark, warm spaces beneath the nail plate.

4

Pink Matrix Regrowth

Vitamin C, Rosehip, and Shea Butter supply essential fatty acids to the germinative nail root, encouraging smooth, clear pink regrowth.

Peer-Reviewed Transungual Science

The 17 Botanical Ingredients & PubMed Citations

Explore the biological mechanisms, active terpenes, and peer-reviewed NIH/PubMed scientific studies supporting each natural oil in the Orivelle formula.

1
Antimicrobial

Tea Tree Oil

Melaleuca alternifolia

Polyphenol protection and accelerated absorption

Rich in proanthocyanidins and linoleic acid, serving as an ultra-lightweight carrier oil that carries active compounds deep into the dorsal nail plate without greasy buildup.

NIH / PubMed Ref:PMC4988453
8
Moisturizer

Sweet Almond Oil

Prunus Amygdalus Dulcis

Softens thickened, brittle nail edges

High in zinc, potassium, and fatty acids that penetrate thickened subungual debris, softening hard keratin so active botanicals can reach the nail bed effectively.

NIH / PubMed Ref:PMC5796020
9
Vitamin

Avocado Oil

Persea Gratissima

Infuses vitamins A, D & E into deep nail layers

Boasts exceptional epidermal and transungual penetration capacity, transporting essential fat-soluble vitamins directly to the proximal nail fold where new nail growth originates.

NIH / PubMed Ref:PMC6600360
10
Protectant

Tsubaki Seed Oil

Camellia Japonica

Forms a moisture-locking hydrophobic barrier

Traditional Japanese botanical oil with more than 82% oleic acid, creating an invisible, breathable moisture-barrier that protects toenails inside damp socks and shoes.

NIH / PubMed Ref:PMC8705358
11
Protectant

Shea Butter

Butyrospermum Parkii

Seals the eponychium and prevents cuticle splitting

Rich in cinnamic acid esters and lupeol, reinforcing the delicate cuticle seal that prevents water, soaps, and fungi from entering beneath the proximal nail fold.

NIH / PubMed Ref:PMC5796020
12
Moisturizer

Macadamia Seed Oil

Macadamia Ternifolia

Replenishes rare Omega-7 palmitoleic acid

One of the richest botanical sources of palmitoleic acid (Omega-7), a lipid naturally found in human sebum that decreases as nails age and become yellowed or brittle.

NIH / PubMed Ref:PMC5796020
13
Protectant

Chilean Hazelnut Oil

Gevuina Avellana

Protects against UV-induced keratin degradation

Native to South America, Chilean hazelnut oil contains natural UV-filtering avellane lipids that shield exposed toenails from sun-induced keratin protein degradation.

NIH / PubMed Ref:PMC6572572
14
Protectant

Meadowfoam Seed Oil

Laminanthes Alba

Stabilizes botanical actives and extends penetration time

Contains unique long-chain fatty acids (over 98% 20+ carbon chains) that resist oxidation, ensuring active essential oils stay potent on the nail surface for hours.

NIH / PubMed Ref:PMC7074312
15
Moisturizer

Jojoba Seed Oil

Simmondsia Chinensis

Transungual carrier mimicking natural human sebum

Structurally identical to human sebum wax esters, allowing it to penetrate through dense keratin plates faster than almost any other vegetable oil, carrying co-ingredients deep into the subungual space.

NIH / PubMed Ref:PMC5796020
16
Anti-inflammatory

Evening Primrose Oil

Oenothera Biennis

Supplies Gamma-Linolenic Acid (GLA) to soothe surrounding skin

An exceptional source of Gamma-Linolenic Acid (GLA), which soothes inflamed periungual tissues, reduces throbbing discomfort, and nourishes the nail bed matrix.

NIH / PubMed Ref:PMC3931201
17
Vitamin

Rosehip Seed Oil

Rosa Canina

Stimulates smooth, ridge-free healthy nail regrowth

Contains natural trans-retinoic acid and provitamin A that encourage proper keratinocyte alignment, resulting in smooth, ridge-free, pink nail regrowth as the old damaged nail grows out.

NIH / PubMed Ref:PMC5485961
