Beauty GENcheckup
Decode your skin's genetic architecture — collagen, aging, hydration, sensitivity — and receive a personalized skincare blueprint.
6 Skin Panels · 17 SNPs · Custom Skincare
Skin Structure & Collagen
Collagen & elastin architecture, skin firmness, premature aging susceptibility. Helps select targeted care products and regeneration strategies.
Antioxidant & Cell Defense
Oxidative stress response, free radical neutralization, UV & pollutant resilience. Guides antioxidant selection — topical and internal.
Inflammation & Skin Reactivity
Sensitivity profiling, redness & irritation tendency, inflammatory skin metabolism. Informs soothing and balancing skincare choices.
Moisture Balance & Skin Barrier
Hydration retention capacity, barrier function, dry & sensitive skin predisposition. Determines ideal textures, lipids, and moisture factors.
Regeneration & Cell Renewal
Skin recovery speed, nocturnal repair cycles, post-stress resilience. Especially relevant for night care and regenerative actives.
Beauty Micronutrient Genes
Vitamin & mineral utilization for skin, hair, and connective tissue. The foundation for personalized "beauty from within" supplement recommendations.
A personalized skin blueprint with targeted recommendations for care products, active ingredients, textures, lipids, and micronutrients — crafted specifically for your genetic skin profile.

Lifestyle GENcheckup
The complete biological audit — weight, sport, nutrition, detoxification, burnout resilience, and longevity from one DNA sample.
7 Tracks · Nutrigenetics · Detox · Telomeres
Carbohydrate Metabolism & Satiety
FTO/FABP2 analysis — how sensitively the body reacts to carbohydrates, how quickly satiety occurs, and snacking tendency. Guides meal structure, timing, and carb quantity.
Eating Behavior & Weight Tendency
Hunger-reward mechanisms, stress/emotional eating patterns, long-term weight trajectory. Not about restriction — about better self-regulation.
Sport & Movement Profiling
Endurance vs. strength response, recovery speed, optimal training form. Produces specific recommendations: sport type, frequency, and session duration in minutes.
Nutrigenetic Analysis (7 markers)
Omega-3 utilization, folate/folat processing, lactose tolerance, iron absorption, vitamin D reaction, caffeine metabolism, salt sensitivity.
Detoxification Enzymes (5 genes)
GSTM1, GSTT1, GSTP1, GPX1, SOD2 — how effectively the body breaks down environmental toxins, neutralizes oxidative stress, and protects cells long-term.
Burnout & Stress Resilience
Stress response genetics, cortisol metabolism, mental recovery capacity. Actionable insights for sustainable energy management.
Longevity & Telomere Mapping
Telomere length predisposition, biological aging rate, cellular longevity markers. The science of how fast — or slow — your body ages.
A complete lifestyle optimization system — personalized sport recommendations (type, frequency, duration), targeted nutrition strategy, detox support protocol, and longevity insights. No diets. No diagnoses. Just your biology, decoded.
