CELLULAR MECHANISM DIRECTORY

Target skin concerns with evidence-based actives.

Every skin concern stems from a distinct cellular pathway: tyrosinase hyperactivity, retention hyperkeratosis, or lamellar lipid depletion. Discover validated actives that address the biological root cause.

DOSSIER: HYPERPIGMENTATIONRead protocol →

Hyperpigmentation & Dark Spots

Post-inflammatory hyperpigmentation (PIH) and solar lentigines develop when melanocytes over-synthesize melanin in response to UV exposure or localized epidermal inflammation.

Primary Actives:
Niacinamide (Vitamin B3)L-Ascorbic Acid (Vitamin C)Azelaic Acid
Biological melanosome transfer inhibition and tyrosinase regulation.
DOSSIER: CLOGGED-PORES-COMEDONESRead protocol →

Clogged Pores & Comedones

Open comedones (blackheads) and closed comedones (whiteheads) form when desquamated keratinocytes mix with oxidized squalene and wax esters, forming dense follicular plugs.

Primary Actives:
Salicylic Acid (BHA)Retinoids
Intra-follicular desquamation and sebaceous duct clearing.
DOSSIER: COMPROMISED-BARRIERRead protocol →

Compromised Barrier & Stinging

An impaired stratum corneum with depleted ceramides, micro-fissures, and heightened sensitivity to ambient air and neutral water.

Primary Actives:
Ceramides & LipidsCentella & Ectoin
Lamellar lipid bilayer replenishment and transepidermal water loss reduction.
DOSSIER: FACIAL-ERYTHEMA-REDNESSRead protocol →

Facial Erythema & Redness

Persistent flushing, microvascular reactivity, and cutaneous erythema associated with skin sensitization or rosacea-prone skin.

Primary Actives:
Azelaic AcidCentella & Ectoin
Microvascular calming and anti-inflammatory cytokine downregulation.
DOSSIER: FINE-LINES-ELASTICITYRead protocol →

Fine Lines & Collagen Loss

Structural cutaneous changes driven by chronological aging and solar elastosis, characterized by degraded collagen fibrils and reduced dermal turgor.

Primary Actives:
RetinoidsSignal Peptides & Copper
Fibroblast receptor stimulation and dermal extracellular matrix maintenance.
DOSSIER: MELASMARead protocol →

Melasma & Hormonal Pigment

Bilateral symmetrical facial hyperpigmentation triggered by reproductive hormones (estrogen/progesterone), solar UV, and visible high-energy light.

Primary Actives:
Azelaic Acid 10–20%Niacinamide (4–5%)
Non-irritating tyrosinase control and visible light defense.
DOSSIER: SKIN-DEHYDRATIONRead protocol →

Epidermal Dehydration & Tightness

A temporary condition where the stratum corneum lacks adequate water content, leading to superficial micro-creasing, tight sensation, and dull light reflection.

Primary Actives:
Hyaluronic Acid & PolyolsCeramides & Lipids
Corneocyte water binding and natural moisturizing factor (NMF) replenishment.
DOSSIER: UNEVEN-ROUGH-TEXTURERead protocol →

Rough Texture & Corneocyte Buildup

A rough, tactilely uneven skin surface caused by un-shed corneocytes accumulating on the stratum corneum.

Primary Actives:
AHA & BHA AcidsRetinoids
Desmosomal shedding normalization and cellular transit optimization.
DOSSIER: EXCESS-SEBUM-OILINESSRead protocol →

Excess Sebum & Shiny T-Zone

Hyperactive sebaceous glands producing excessive liquid squalene, triglycerides, and wax esters across the forehead, nose, and chin.

Primary Actives:
NiacinamideSalicylic Acid (BHA)
Sebaceous lipogenesis suppression and follicular drainage.
DOSSIER: DULL-COMPLEXIONRead protocol →

Dullness & Surface Light Scatter

A flat, lackluster skin appearance caused by irregular micro-roughness scattering light, combined with oxidative stress and environmental particulate accumulation.

Primary Actives:
L-Ascorbic Acid (Vitamin C)AHA & BHA Acids
Specular optical reflection restoration through cellular turnover and antioxidant protection.
DOSSIER: INFLAMMATORY-ACNE-BREAKOUTSRead protocol →

Inflammatory Acne & Breakouts

Erythematous papules, pustules, and localized inflammation provoked by follicular micro-plugging, anaerobic microbial colonization, and toll-like receptor cascade activation.

Primary Actives:
Salicylic Acid (BHA)RetinoidsNiacinamide (Vitamin B3)
Cutibacterium acnes suppression, follicular desquamation, and cytokine regulation.
DOSSIER: POST-INFLAMMATORY-ERYTHEMARead protocol →

Post-Inflammatory Erythema (PIE)

Pink, red, or purple flat macules that linger after inflammatory blemishes resolve, caused by damaged, dilated microcapillary beds in the papillary dermis.

Primary Actives:
Centella & EctoinNiacinamide
Microvascular ectasia resolution, capillary repair, and daylight photodamage defense.
DOSSIER: SKIN-LAXITY-SAGGINGRead protocol →

Loss of Firmness & Skin Laxity

Progressive weakening of dermal structural scaffolding, resulting in diminished tissue recoil, ptosis, and reduced facial contour definition.

Primary Actives:
Signal Peptides & CopperRetinoids
Elastin fibrillogenesis, dermal-epidermal junction remodeling, and glycation mitigation.
DOSSIER: UNDER-EYE-DARK-CIRCLES-PUFFINESSRead protocol →

Periorbital Dark Circles & Puffiness

Bluish-purple vascular shadowing, post-inflammatory periorbital pigmentation, and morning lymphatic fluid stagnation in the delicate peri-ocular zone.

Primary Actives:
Signal Peptides & CopperNiacinamide
Microcapillary hemocateresis, lymphatic drainage, and orbital dermal thickening.
DOSSIER: ENLARGED-PORES-FOLLICULAR-LAXITYRead protocol →

Enlarged Pores & Follicular Laxity

Visibly dilated pilosebaceous orifices across the nose, medial cheeks, and forehead, exacerbated by heavy sebum flow and loss of surrounding collagen support.

Primary Actives:
NiacinamideSalicylic Acid (BHA)
Perifollicular collagen reinforcement, sebum compaction release, and optical refinement.
DOSSIER: XEROSIS-SEVERE-DRY-SKINRead protocol →

Xerosis & Cutaneous Scaling

True lipid-deficient dry skin characterized by a depleted intercellular lipid matrix, micro-fissuring, visible powdery desquamation, and pruritus.

Primary Actives:
Ceramides & LipidsHyaluronic Acid & Polyols
Physiological lipid replenishment, natural moisturizing factor synthesis, and desquamation control.
