We begin by evaluating all 21 Universkin active ingredients against your skin diagnostic. Each ingredient is assigned to one or more functional categories:

• Antioxidants (e.g., Ferulic Acid, SOD, Ascorbic Acid)
• Barrier restorers (e.g., D-Panthenol, Aloe Vera, Niacinamide)
• Sebum regulators (e.g., Zinc Sulfate, Salicylic Acid)
• Brightening agents (e.g., Kojic Acid, Arbutin, Tranexamic Acid)
• Anti-inflammatories (e.g., Madecassoside, Azelaic Acid, Troxerutin)
• Exfoliants & texture refiners (e.g., Glycolic Acid, Phytic Acid)
• Cell turnover & anti-aging (e.g., Retinal, DMAE, Isoflavones, Retinol)
• Antibacterial/anti-acne agents (e.g., Lactopeptide, Salicylic Acid)

Each ingredient's expected effect is scored across eight skin concern zones (yellow, pink, red, blue, orange, grey, green, brown), with dose-response logic based on 1–3 capsule levels.
We’re mapping each ingredient against your skin concern profile, scoring how strongly it addresses oxidative stress, inflammation, dryness, pigmentation, acne, and more.

We now evaluate how appropriate each ingredient is for you specifically. For this, we use a rule-based engine that combines:

• Your measured dysfunction scores in each concern zone
• Traits like skin thickness, phototype, ethnicity, age group, sensitivity, and medical history
• Dermatological contraindications (e.g., avoiding glycolic acid for rosacea, avoiding retinal during pregnancy)

Each ingredient is assigned one of four levels:

• Must have (level 4)
• Strongly recommended (level 3)
• Can be used (level 2)
• Should not be used (level 1 or 0)

These scores are calculated separately for the face, eye contour, and neck and décolleté, as tolerance and concerns vary by region.
We’re applying over 400 dermatological decision rules to evaluate ingredient safety, relevance, and synergy, including phototype-based pigmentation risks and inflammatory triggers.

With the ingredients scored, we are now entering the optimization phase. We will select a combination of 3 actives for both morning and evening that maximizes therapeutic impact while respecting all formulation constraints.
To achieve this, we are using a multi-objective constraint solver that evaluates hundreds of thousands of candidate combinations. Each candidate is assessed using a scientific function that measures how closely the formula’s action profile matches your skin’s dysfunction vector.
We are enforcing clinical formulation standards to ensure efficacy, stability, and skin compatibility. These include considerations such as:

• Ensuring ingredients prone to photosensitivity or reactivity are reserved for nighttime use
• Managing ingredient combinations to preserve pH balance and avoid potential irritation
• Supporting more active compounds with skin-barrier-strengthening agents when needed
• Modulating the number of intensive pigment-correcting actives to match individual pigmentation severity

We are now in the final phase; we complete your routine by selecting supportive skincare products that work in harmony with your personalized serums.

• Cleansers are selected based on your sebum activity, barrier sensitivity, and cleansing tolerance.
• Moisturizers are tailored to your skin’s hydration status, structural integrity, and inflammatory load. We assess whether your skin requires lightweight emulsions for sebum control, richer textures for barrier restoration, or calming actives to reduce redness and discomfort.
• Sun protection is matched to your Fitzpatrick phototype, pigmentation risk, and presence of sensitizing actives. If your treatment includes photo-reactive compounds or if melanin instability is detected, we recommend a mineral sunscreen with high UVA/UVB coverage and dermo-protective properties.
