BIOACTIVE CONCENTRATES™
High-potency, skin-friendly Bioactive Concentrates™ for dry, sensitive and aging skin, with active ingredient loads starting at 15%+.
Made without unnecessary fillers, our barrier-first formulas combine clinically studied actives at concentrations informed by peer-reviewed research with synergistic research-backed botanicals rooted in global traditional medicine for multiple mechanisms of action.
Designed for deep hydration, short term correction, and long term skin health.
Hand-packed with a silver spatula, with a touch of indulgence.
Formulated for Dry, Sensitive, and Aging Skin
Ideal for skin that is:
- Experiencing hormonal changes in women and men, including menopause and declining testosterone.
- Frequently exposed to shaving, harsh weather, travel, or other environmental stressors
- Very dry, dehydrated, sensitive, or easily irritated
- Compromised following use of acids, retinoids, or other active ingredients
- Showing visible signs of aging, including fine lines, wrinkles, or loss of firmness
DESIGNED TO TARGET FIVE INTERCONNECTED BIOLOGICAL DRIVERS OF SKIN FUNCTION
As hormones naturally shift with age, skin can experience changes in collagen, elasticity, hydration, and lipid composition, making dryness and visible signs of aging more pronounced. We formulate to support the skin functions affected by these changes, not just the visible signs they leave behind.
🟨 Dehydration
The stratum corneum typically contains approximately 15–20% water. Below roughly 10%, skin can become dry, rough, tight, and less flexible.
🟦 Barrier Breakdown
Ceramides make up approximately 50% of stratum corneum lipids by weight, alongside cholesterol and free fatty acids. When this lipid matrix is disrupted, transepidermal water loss can increase and barrier function can decline.
🟥 Oxidative Stress
UV exposure is a major contributor to visible skin aging, with one study estimating that UV exposure may account for up to 80% of visible facial aging. UV radiation also generates reactive oxygen species that contribute to oxidative stress in the skin.
🟩 Microbiome Imbalance
Human skin hosts a diverse microbial ecosystem, with studies identifying more than 1,000 bacterial species across different skin sites.
🟫 Structural Decline
Skin collagen declines by approximately 1% per year during adulthood. During menopause, declining estrogen can accelerate this process, with studies estimating that skin may lose about 30% of its collagen during the first five years after menopause. In men, collagen loss tends to occur more gradually with age.
FEATURED FORMULATIONS
Designed to Work Alone. Built to Work Better Together.
Each Bioactive Concentrate™ can be used on its own or combined with complementary formulations as part of a personalized protocol. Rather than organizing skincare solely by skin type, Steinder Weisen® organizes recommendations around five interconnected aspects of skin function.

LAMELLARE ⮕
Structural Lipid Crème
Very rich barrier-rebuilding and structural-support formula with architecture especially suited to very dry, lipid-depleted, mature, hormonally changing, and barrier-compromised skin.
BORAGE OIL
One of the richest botanical sources of gamma-linolenic acid (GLA), an essential fatty acid relevant to the increased dryness associated with menopausal skin.
3.74% GHK-Cu + PALMITOYL TRIPEPTIDE-38
Copper peptides support skin repair and extracellular-matrix renewal, while Palmitoyl Tripeptide-38 supports the skin matrix for improved firmness and smoother-looking skin.
