THE FORMULARY
Bioactive Concentrates™ formulated for very dry, sensitive and aging skin
High-potency, multi-pathway and barrier-first: clinical actives at concentrations informed by peer-reviewed research, paired with lipids and botanicals from global healing traditions, working through the skin's different pathways for short-term correction and long-term skin health. Made au bain-marie to help preserve potency.
LAMELLARE™ is a rich, substantial Structural Crème addresses visible structural aging: reduced firmness, fine lines, and a dry, fragile feel. A 3.74% multi-peptide complex pairs GHK-Cu copper peptide with signaling peptide palmitoyl tripeptide-38 and complementary hexapeptide-11. GLA-rich borage oil, ceramides, and cholesterol replenish lipids, while a 17.96% four-humectant system attracts and retains moisture to help maintain lasting hydration.

ROWANE™ Triple Vitamin C Émulsion is a multi-pathway antioxidant treatment formulated with dry, sensitive, rosacea-prone skin in mind, including those who find low-pH L-ascorbic acid serums with penetration enhancers difficult to tolerate. An 8.88% triple vitamin C complex joins Kakadu plum, recognized as one of the world’s richest natural sources of vitamin C, niacinamide, azelaic acid, and hops to brighten dullness and uneven-looking tone. Ferulic acid, tocotrienols, and carotenoid-rich glow oils complement its antioxidant system, supporting radiance and helping defend skin against free radicals generated by UV exposure, pollution, and other environmental stressors that contribute to visible aging.

LISSE™ Exfoliant Concentré is designed for dry, sensitive, aging skin. As skin ages, its natural renewal cycle slows, allowing dead surface cells to accumulate and contribute to roughness and dullness. A 9.52% AHA blend of mandelic and lactic acids, paired with 3.40% N-acetyl glucosamine, helps lift this buildup for smoother texture, greater radiance, and more even-looking tone, preparing a smoother surface for the treatments that follow. With 5% panthenol complemented by a postbiotic ferment and a 10 botanical complex including watercress, burdock, sage, lemon peel, ivy, soapwort, bladderwrack, willow bark, and witch hazel.

BUFFÈRE™ Universal Barrière Booster. Allergen Aware by Design™ Made for extremes: very dry, reactive skin and demanding treatment routines. With 7% ectoin, this treatment amplifier adds concentrated hydration and barrier support alongside actives. For routines involving OTC or prescription treatments such as tretinoin or minoxidil, and for post-procedure care, use as directed by your treating clinician. Formulated without niacinamide, tocopherol, fatty alcohols, or nut- and grain-derived ingredients—a deliberate approach for skin with specific ingredient sensitivities.

RÉAU™ Omega Retinoid Concentré is a multi-pathway retinoid formulated for dry, sensitive skin. Retinyl linoleate provides approximately 0.36% retinol by molecular weight, bound to the essential omega-6 fatty acid linoleic acid, alongside bakuchiol and CoQ10. Rich botanical oils, cupuaçu butter, and squalane replenish moisture while supporting smoother texture and more even-looking skin.

BASTINA™ Overnight Lipid Sealant is the last step in the PM routine of The Layland Method™. It forms a protective lipid film on the skin, helping seal in moisture and reduce water loss overnight. Features a North American desert botanical complex with desert sand verbena, agave, Joshua tree, prickly pear, ocotillo, and creosote bush. Inspired by desert plants adapted to arid conditions, it reflects a simple principle: finding moisture is only part of the challenge. Keeping it from escaping matters just as much.

A little goes a long way.
