Niacinamide
Vitamin B3
Niacinamide is one of the most extensively studied ingredients in modern skincare, with benefits that reach far beyond basic hydration. A form of vitamin B3, it is especially valued for brightening uneven skin tone, improving the appearance of dark spots, strengthening the skin barrier and smoothing visible texture.

Hyaluronic Acid
Sodium Hyaluronate
Hyaluronic Acid is naturally present throughout the skin and has an extraordinary ability to bind and retain water. That makes it one of skincare’s most valuable ingredients for dehydration, tightness, fine dehydration lines and skin that has lost its fresh, plump appearance.

Panthenol
Pro-Vitamin B5
Panthenol, better known as Pro-Vitamin B5, is one of skincare's most valuable ingredients when skin has been pushed too far. Dry weather, aggressive cleansing, over-exfoliation, retinoids and other strong actives can leave the barrier compromised and skin feeling tight, irritated, rough, sensitive or simply uncomfortable. Panthenol helps support the skin as it recovers.

Beta-Glucan
B-Glucan
Beta-Glucan is a naturally occurring polysaccharide found in sources including oats, yeast, mushrooms and certain algae. Once known primarily for its immune-modulating properties, it has become an increasingly important skincare ingredient because it does something particularly valuable: it helps skin hydrate, calm, repair and become more resilient at the same time.

Sodium PCA
Natural Moisturizing Factor
Sodium PCA is one of the substances skin naturally uses to keep itself hydrated. It is an important component of the skin’s Natural Moisturizing Factor, or NMF—the water-binding system within the outermost layer of the skin that helps maintain softness, flexibility and healthy hydration. When Natural Moisturizing Factor becomes depleted, skin doesn't simply feel dry. It can become tight, rough, flaky and less flexible, and fine dehydration lines can appear more pronounced. This depletion can occur with age, low humidity, harsh cleansing, over-exfoliation and other forms of barrier stress.

Blue Tansy
Tanacetum Annuum Flower Oil
Blue Tansy begins as a small yellow flower, yet after distillation its essential oil emerges an extraordinary shade of deep blue. The transformation comes from chamazulene, the blue aromatic compound formed during distillation and one of the constituents that makes Blue Tansy particularly compelling for visibly stressed skin.

Camellia Seed Oil
Camellia Oleifera Seed Oil
Camellia is one of East Asia's great beauty oils. For centuries, oils pressed from Camellia seeds have been part of beauty and personal-care traditions across Japan, China and Korea. In Japan, Camellia oil is known as tsubaki oil, with a history reaching back generations; by the Edo period it had become especially celebrated as a traditional beauty oil. That legacy continues today, with Japanese Camellia-oil houses still producing oils that have been passed from one generation to the next.

Daikon Seed Extract
Raphanus Sativus (Radish) Seed Extract
Daikon may be familiar as the crisp white radish used throughout Japanese and Korean cuisine, but its seeds produce something quite different: an exceptionally elegant botanical lipid prized for both the way it conditions the skin and the remarkable texture it creates.

Meadowfoam Seed Oil
Limnanthes Alba Seed Oil
Meadowfoam Seed Oil comes from the tiny seeds of a white flowering plant native to the Pacific Northwest of North America. Its delicate appearance hides an unusually sophisticated oil. Unlike most botanical oils, Meadowfoam is dominated by very long-chain fatty acids, particularly eicosenoic and docosenoic acids, giving it a composition—and behavior on the skin—that is distinctly its own.

Squalane
Olive-Derived Squalane
Squalane has a remarkable affinity with the skin because it is closely related to squalene, a lipid naturally present in our own sebum. Squalene is part of the skin's natural surface lipids, where it contributes to softness, flexibility and the protective environment that helps keep skin comfortable and healthy looking. Squalane is its more stable form, prized in skincare for delivering that same beautiful skin compatibility.

Jojoba
Simmondsia Chinensis Seed Oil
Jojoba is unlike almost every other botanical oil in skincare because technically, it isn't an oil at all. It is a liquid wax, composed primarily of long-chain wax esters that resemble components naturally present in human sebum. This gives Jojoba an exceptional affinity with the skin—but its benefits go considerably further.

Caprylic/Capric Triglyceride
Fractionated Coconut
Caprylic/Capric Triglyceride is a refined, lightweight emollient made primarily from caprylic and capric fatty acids, typically derived from coconut, combined with glycerin. Although its origins are botanical, it behaves very differently from traditional coconut oil: it is lighter, silkier and exceptionally elegant on the skin.

Jasmine Sambac
Jasminum Sambac Flower Extract
Jasmine is one of perfumery’s most sensual flowers, prized for an intoxicating scent that is lush, warm, floral and almost narcotic. Native to tropical Asia and deeply woven into Indian and Southeast Asian beauty and fragrance traditions, Sambac is richer and more seductive than the lighter jasmine notes many people know.

Vitamin E
Tocopherol
Vitamin E is often treated like a supporting ingredient in skincare. In reality, it is one of the antioxidants naturally present in human skin, helping protect the lipids that make up cell membranes and the skin barrier from oxidative damage. Our bodies even deliver Vitamin E to the skin's surface through sebum.

Prickly Pear Seed Oil
Opuntia Ficus-Indica Seed Oil
Prickly Pear Seed Oil is one of the most precious botanical oils used in skincare. Extracted from the tiny seeds of the prickly pear cactus fruit, it takes an extraordinary amount of fruit to produce a relatively small amount of oil, making genuine Prickly Pear Seed Oil especially prized.

Kalahari Melon Seed Oil
Citrullus Lanatus Seed Oil
Kalahari Melon grows in the extreme heat, intense sun and prolonged drought of Southern Africa's Kalahari region, surviving where water can be extraordinarily scarce.

Cloudberry Seed Oil
Rubus Chamaemorus Seed Oil
Cloudberry is a rare golden berry that grows in the subarctic regions of Northern Europe and Scandinavia, surviving intense cold, long winters and an exceptionally short growing season. Its tiny seeds produce a precious oil rich in omega-3 and omega-6 essential fatty acids, vitamin E compounds, carotenoids and powerful antioxidant plant compounds—a particularly compelling profile for skin showing signs of aging.

Rosehip Seed Oil
Rosa Canina Seed Oil
Rosehip has become one of skincare's most celebrated oils for fine lines, wrinkles and photoaged skin—so much so that it is sometimes called “nature's Retin-A.” It isn't Retin-A, but the comparison reflects Rosehip's reputation for supporting visible skin renewal and smoother, more youthful-looking skin.

Marula Oil
Sclerocarya Birrea Seed Oil
Pressed from the kernels of the Marula tree of Southern Africa, Marula Oil has traditionally been used to care for skin exposed to a hot, dry climate. Its modern appeal is backed by something relatively unusual for a botanical oil: clinical research directly on human skin.

Evening Primrose Oil
Oenothera Biennis Oil
Evening Primrose is distinguished by its concentration of gamma-linolenic acid (GLA), an omega-6 fatty acid relatively uncommon in botanical oils and closely connected with healthy skin function, inflammatory balance and the skin's lipid environment.
Read more →
Sea Buckthorn Fruit Oil
Hippophae Rhamnoides Fruit Oil
Sea Buckthorn Fruit Oil is one of the most visually distinctive oils in skincare. Its naturally intense golden-orange color comes from its extraordinary concentration of carotenoids, the antioxidant pigments responsible for the vivid colors of many fruits and vegetables. But its real distinction is its unusually high concentration of palmitoleic acid, commonly known as Omega-7—a fatty acid naturally present in human skin lipids but relatively rare in botanical oils.

Bulgarian Rose
Rosa Damascena Flower Extract
Bulgarian Rose is one of the most precious and prized botanical materials in luxury beauty. Grown in Bulgaria’s legendary Rose Valley, Rosa damascena has been cultivated for centuries for its extraordinary aromatic oil. Its rarity is remarkable: approximately 3,500–5,000 kilograms of fresh rose blossoms may be required to produce just one kilogram of rose oil. The flowers are traditionally hand-harvested in the cool morning hours and quickly distilled, making genuine Bulgarian Rose exceptionally labor-intensive—and one of the most expensive natural oils used in skincare and fine fragrance.

Roman Chamomile
Anthemis Nobilis Flower Oil
Roman Chamomile has been prized for centuries as one of the botanical world's great calming and comforting herbs.

Shea Butter
Butyrospermum Parkii Butter
Shea Butter has been treasured across West Africa for centuries, where the nuts of the shea tree are transformed into a rich botanical butter unlike almost any other. Its reputation for nourishing dry skin is well known. What is far less known is the sophisticated chemistry behind it.

Buriti Oil
Mauritia Flexuosa Fruit Oil
Deep within Brazil’s Amazon and Cerrado wetlands grows the Buriti palm, a towering palm so closely associated with water that its presence can signal an oasis in an otherwise dry landscape. Known in Brazil as the “tree of life,” Mauritia flexuosa produces clusters of extraordinary reddish-brown fruits covered in scales, concealing brilliant golden-orange flesh underneath. From that fruit comes Buriti Oil—an intensely colored botanical oil that remains relatively unfamiliar in Western skincare despite an exceptional composition.

Pomegranate Seed Oil
Punica Granatum Seed Oil
For thousands of years, the pomegranate has symbolized beauty, vitality and renewal across Persia, the Mediterranean and the Middle East. Hidden within its jewel-like seeds is an unusually sophisticated oil whose modern research gives that ancient association with renewal an entirely new meaning.

Aloe Vera
Aloe Barbadensis Leaf Juice
Aloe Vera is so familiar that its sophistication is easy to overlook. Used for thousands of years to care for burned, injured and intensely dry skin, its clear inner leaf gel contains a complex mixture of polysaccharides, amino acids, minerals, sterols and antioxidant compounds.

Ceramides
Skin-Identical Barrier Lipids
Ceramides aren't simply moisturizing ingredients. They are lipids naturally found in your own skin, where they make up a major portion of the lipid structure of the stratum corneum your skin's outer protective barrier. That barrier is responsible for keeping essential water in and environmental stressors out. Ceramides are part of what holds that protective seal together.

Raspberry Seed Oil
Rubus Idaeus Seed Oil
Inside the tiny seeds of the red raspberry is an exceptionally nutrient-dense oil with a fatty-acid profile particularly suited to dry, mature and moisture-depleted body skin. Raspberry Seed Oil is naturally rich in both omega-6 linoleic acid and omega-3 alpha-linolenic acid, two essential fatty acids the body cannot manufacture on its own and must obtain from outside sources.

Japanese Green Tea
Camellia Sinensis Leaf Extract
Green Tea has been treasured in Japan for centuries, but within its delicate leaves is some remarkably sophisticated skin chemistry. Green Tea is exceptionally rich in polyphenols called catechins, including its most celebrated compound, EGCG—epigallocatechin gallate—one of the most extensively studied botanical antioxidants in skincare.

Cocoa Butter
Theobroma Cacao Seed Butter
Cocoa Butter comes from the seeds of Theobroma cacao—literally translated as “food of the gods.” Best known as the luxurious fat that gives chocolate its extraordinary melt, Cocoa Butter has an equally beautiful relationship with skin. At body temperature, its firm crystalline structure begins to melt, creating the rich, enveloping layer that makes it exceptional for dry, tight and less supple body skin.

Allantoin
Allantoin is one of skincare's quiet overachievers. Best known for its ability to calm and comfort irritated skin, it also has an important relationship with rough texture, skin renewal and repair—making it particularly valuable in body care.
