Epidermal Growth Factor / EGF
Epidermal Growth Factor is a signalling protein involved in:
Cellular communication + epidermal renewal + tissue-repair pathways.
Lamelle states that the EGF technology used in the serum supports:
Keratinocytes + fibroblasts
and helps promote production of:
Collagen + elastin + hyaluronic acid.
Keratinocytes make up the majority of the:
Epidermis
while fibroblasts are central to producing structural components within the:
Dermis.
For Chris & Alley:
Supports communication between skin cells to promote renewal, hydration and the structural proteins associated with firmer, more resilient-looking skin.
Avoid describing EGF as physically:
“Replacing lost collagen.”
Its role is better explained as supporting cellular signalling associated with the skin's own renewal processes.
Fibroblast Growth Factor / FGF
Fibroblast Growth Factor forms part of the serum's dermal-support system.
Lamelle specifically states that FGF supports:
Endothelial cells + fibroblasts + keratinocytes.
Fibroblasts play a central role in producing components of the extracellular matrix, including:
Collagen + elastin + glycosaminoglycans.
For Chris & Alley:
Supports fibroblast and skin-cell activity associated with dermal structure, firmness and skin renewal.
Insulin-Like Growth Factor-1 / IGF-1
IGF-1 is another signalling factor within the serum's growth-factor complex.
Lamelle positions it as enhancing the activity of:
EGF + FGF
and contributing to a:
Plumper appearance in photoaged skin.
For Chris & Alley:
Complements the EGF and FGF system to support skin renewal and a firmer, plumper-looking complexion.
This should not be confused with:
Injectable or systemic growth-hormone treatment.
The ingredient is part of a:
Topical cosmetic formulation.
Copper Tripeptide
Copper peptides are naturally relevant to skin repair because copper acts as a cofactor in several biological processes.
They are widely used in age-management formulas for supporting:
Collagen + elastin + tissue repair + antioxidant defence.
The published INCI for this product includes:
Copper Tripeptide-1
alongside an additional copper peptide.
For Chris & Alley:
Supports skin repair, resilience and structural protein production while complementing the serum's growth-factor technologies.
Thioredoxin
This is an important correction to the existing Chris & Alley page.
The page currently says:
“Thyroidoxin.”
Lamelle's own technical material refers to:
Thioredoxin.
Thioredoxin is involved in cellular:
Redox regulation + antioxidant defence.
For Chris & Alley:
Provides complementary antioxidant support, helping protect skin cells against oxidative stress as part of the serum's regenerative complex.
I would therefore replace:
Thyroidoxin
with:
Thioredoxin
throughout the product listing.
Sodium Hyaluronate + Hyaluronic Acid
Published ingredient information for the serum includes both:
Sodium Hyaluronate + Hyaluronic Acid.
These humectants help bind water within the skin and support:
Hydration + plumpness + smoothness + comfort.
Their inclusion complements the growth-factor strategy by ensuring the serum is not focused solely on cellular signalling.
For Chris & Alley:
Provides direct humectant hydration to support a smoother and more plump-looking complexion.
Hydrolysed Elastin
Hydrolysed Elastin provides complementary skin-conditioning support in a formula already strongly positioned around:
Firmness + elasticity + resilience.
It should not be presented as literally rebuilding the skin's elastic network simply by being applied topically.
A more measured customer-facing explanation is:
Provides skin-conditioning peptides that complement the formula's elasticity-supporting technology.
Panthenol
Panthenol is a provitamin form of:
Vitamin B5.
It supports:
Hydration + soothing + barrier comfort.
This is particularly helpful when the serum is being incorporated into more intensive age-management routines that may also contain:
Retinoids + exfoliating acids + Vitamin C.
Aloe Vera
Published INCI information includes:
Aloe Barbadensis Leaf Extract.
Aloe provides complementary:
Soothing + hydrating + skin-conditioning support.
Vitamin E / Tocopherol
The published formula contains:
Tocopherol + Tocopheryl Acetate.
These provide complementary:
Antioxidant support
and help protect the formula's lipid components from oxidative degradation.
Centella Asiatica
Published ingredient information also lists:
Centella Asiatica Extract.
Centella is widely used to support:
Soothing + skin recovery + barrier resilience.
Its presence complements the regenerative positioning of the formula.
