Cathepsin D Analogue Technology
The defining technology within the Cathepzyme range.
Lamelle describes this patented active as mimicking the activity of Cathepsin D, an enzyme naturally involved in the skin’s surface desquamation process.
Cathepsin D activity can change with age, contributing to less efficient surface-cell shedding and a complexion that appears:
Duller + rougher + less smooth.
Cathepzyme 1 is designed to support a more normal exfoliation pattern without relying on aggressive resurfacing.
For Chris & Alley, I would describe the visible outcome as:
Supports gentle, even surface-cell renewal for smoother and more radiant-looking skin.
Avoid saying it literally:
Replaces the skin’s own enzymes
or permanently alters cellular turnover.
Mucor Miehei Extract
The full INCI lists Mucor Miehei Extract high in the formulation.
This enzyme-derived ingredient appears to form part of the Cathepzyme enzymatic system.
Because Lamelle does not currently provide a public technical breakdown mapping each proprietary component to its exact INCI declaration, I would keep:
Cathepsin D analogue
as the manufacturer technology name and:
Mucor Miehei Extract
in the formal ingredient list.
Do not independently assign a percentage.
Phytic Acid
A gentle exfoliating and complexion-supportive ingredient.
Lamelle specifically identifies Phytic Acid as an:
Exfoliating + brightening pigmentation inhibitor.
For customer-facing copy, I would translate this to:
Provides complementary surface-refining and brightening support while helping improve uneven-looking pigmentation.
It is not necessary to position this as a strong acid peel.
Aloe Barbadensis Leaf Extract
Provides:
Hydrating + soothing + skin-conditioning support.
This is particularly useful in a product intended for sensitive skin.
Glycerin
A humectant helping attract water and maintain skin hydration.
This helps support a softer skin feel after exfoliation.
Sodium Hyaluronate
A form of Hyaluronic Acid providing complementary:
Hydration + suppleness + moisture support.
Because Cathepzyme 1 is rinsed off after only three minutes, this remains supportive rather than equivalent to a dedicated leave-on HA serum.
Tocopherol / Vitamin E
Provides complementary:
Antioxidant + skin-conditioning support.
Jojoba Seed Oil + Wheat Germ Oil
Provide light emollient and conditioning support within the broader botanical complex.
Chamomile Extract
Helps support skin comfort and provides soothing botanical conditioning.
Centella Asiatica + Cucumber + Nettle + Horsetail + Chlorella
A broad botanical complex providing complementary:
Conditioning + antioxidant + soothing support.
These are supporting ingredients rather than the primary exfoliating actives.

Use 2–3 times per week.
Cleanse the skin and pat completely dry.
Apply approximately:
3 pumps
to the face using the fingertips and gently distribute in circular movements.
Leave on for:
3 minutes only.
Rinse thoroughly with lukewarm water or gently remove with damp facial sponges or a soft wet cloth.
Follow with your prescribed:
Serum → Moisturiser.
Morning After Use
Apply:
Broad-spectrum SPF 50+
as part of your normal daytime routine.
If Skin Is Very Sensitive
Begin with:
1–2 applications per week
and progress toward the manufacturer's 2–3 times weekly recommendation if the skin remains comfortable.
Do not extend the contact time simply because the treatment feels gentle.
