Every ingredient in the SRX Beauty Protocol is in the formula for a specific reason. Not because it sounds impressive on a label. Not because it trends well. Because it has a defined role in a defined biological process that affects how your skin looks and ages.
This is a full breakdown — what's in each formula, why it's there, and what the biology actually says.
Sculpt — Rise and Thrive (Morning Formula): the collagen synthesis window
The morning formula is built around one clinical insight: collagen synthesis peaks alongside cortisol and metabolic activation in the morning hours. Getting the right inputs into the system at the right time is the difference between passive supplementation and targeted biological activation.
Hydrolysed Marine Collagen
The primary structural input. Hydrolysed into peptides small enough to cross the intestinal wall and be delivered systemically to the dermal fibroblasts where collagen is synthesised. Marine collagen is predominantly Type I — the primary collagen type in skin. Taken in the morning to align with peak synthesis activity.
Algae-Oil DHA
An omega-3 fatty acid sourced from algae rather than fish oil — more sustainable, free from the oxidation risk of fish oil powders, and equally bioavailable. DHA is the structural fat of skin cell membranes. It governs cell membrane fluidity — the property that determines how efficiently nutrients enter and waste exits skin cells. DHA also reduces inflammatory skin responses at the membrane level and supports the synthesis of resolving lipids that actively resolve inflammation. Most ingestible beauty products don't include DHA at all.
Sodium Hyaluronate (Low Molecular Weight)
This is not the same compound as the hyaluronic acid in your serum. Sodium hyaluronate in its low-molecular-weight form has a molecular size small enough to cross the intestinal epithelium and be delivered systemically to skin tissue. Standard hyaluronic acid molecules are too large for this. When systemically delivered, sodium hyaluronate binds water at up to 1,000 times its own weight in the dermal extracellular matrix — producing hydration that shows as plumpness, not just surface moisture.
Coenzyme Q10 (CoQ10)
A cofactor in mitochondrial energy production that declines significantly after 35. Skin cells, particularly the fibroblasts responsible for collagen synthesis, are energetically expensive — CoQ10 supports the ATP production they require. It also acts as a lipid-soluble antioxidant protecting newly synthesised collagen from oxidative degradation. CoQ10 is in both Sculpt and Exude because the morning and overnight windows each have distinct energetic demands.
Natural Guarana Extract
Guarana provides caffeine alongside theobromine and theophylline — the combination that produces sustained cognitive clarity and metabolic activation without the cortisol spike of isolated caffeine sources like coffee. This is why Sculpt produces morning energy without the crash pattern most women recognise from caffeine dependency.
Acerola Extract (Natural Vitamin C)
Vitamin C is an essential cofactor in collagen synthesis — specifically in the hydroxylation reactions that stabilise the collagen triple helix structure. Without adequate Vitamin C, collagen fibres form incorrectly. Acerola is a whole-food Vitamin C source with significantly higher bioavailability than synthetic ascorbic acid, and it delivers the bioflavonoid cofactors that synthetic vitamin C lacks.
Full B-Vitamin Complex (all eight B vitamins)
Thiamine (B1) — energy metabolism. Riboflavin (B2) — cellular energy and skin cell renewal. Niacinamide (B3) — skin barrier integrity, sebum regulation, and DNA repair in skin cells. Pantothenic Acid (B5) — wound healing and barrier function. Pyridoxine (B6) — amino acid metabolism and neurological stress regulation. Biotin (B7) — keratin infrastructure, the protein matrix of skin, hair and nails. Folic Acid (B9) — cell division, the mechanism behind skin renewal. Cyanocobalamin (B12) — methylation pathways governing skin cell gene expression.
Vitamin K2 (Menaquinone)
Vitamin K2 directs calcium into bone and away from soft tissue — supporting skin elasticity and vascular wall health. It works synergistically with Vitamin D3 in the evening formula. K2 is absent from most beauty supplements and substantially underrepresented in standard multivitamins.
Beta Carotene
A provitamin A carotenoid that supports skin cell turnover and provides natural UV protection at the cellular level. The body converts beta carotene to retinol as required — without the overdose risk of preformed Vitamin A.
Magnesium Citrate
The most bioavailable magnesium form. A cofactor in over 300 enzymatic reactions including collagen hydroxylation. In Sculpt, it supports morning ATP production and collagen synthesis cofactor chemistry.
Restore — Glow with the Flow (Daytime Formula): the cellular hydration and delivery window
Restore is built on a mechanism that no other ingestible beauty product has formulated around: the electrolyte system that opens cellular hydration channels is the same system that enables amino acid transport across cell membranes.
Sodium Chloride — 1,000mg
At 1,000mg this is a therapeutic electrolyte dose. Sodium is the primary driver of cellular osmotic pressure — the force that pulls water into cells and creates the electrochemical gradient that amino acid transporters depend on. Without adequate sodium, amino acids cannot cross the cell membrane efficiently regardless of circulating concentration. This is the gateway the rest of Restore depends on.
Potassium Chloride
Maintains the sodium-potassium pump — the membrane mechanism that governs nutrient uptake and cellular waste removal. Potassium depletion collapses this pump and with it the efficiency of every other component in the formula.
Calcium Lactate
Superior bioavailability to calcium carbonate. Calcium supports cell signalling pathways involved in collagen gene expression and acts as a cofactor in the enzymatic assembly of collagen fibres.
Glycine
The most abundant amino acid in collagen — every third position in the collagen triple helix is glycine. It is also the rate-limiting amino acid in collagen synthesis: supplementation directly increases the body's collagen production capacity. No other single amino acid intervention has a more direct impact on collagen output.
L-Proline
Provides the collagen triple helix with its distinctive shape and tensile strength. Hydroxyproline, derived from proline, is one of the most reliable biomarkers of active collagen synthesis.
L-Lysine
Essential for collagen crosslinking — the process that converts individual collagen chains into structurally stable, mature tissue. Lysine also enhances cellular calcium uptake, reinforcing the electrolyte delivery system.
L-Arginine and L-Citrulline
Together, these produce a sustained nitric oxide signal. Arginine is the direct nitric oxide precursor. Citrulline converts to arginine in the kidneys with higher bioavailability, extending the nitric oxide production window through the afternoon. Nitric oxide dilates peripheral blood vessels — increasing circulation to skin tissue and ensuring the electrolytes and amino acids in Restore are delivered to the dermal layer where collagen is produced.
Glutamine
The primary fuel source for intestinal epithelial cells — the cells forming the gut barrier through which every other ingredient in this formula must pass. Glutamine maintains gut barrier integrity, protecting absorption efficiency and reducing intestinal permeability. It is the absorption guardian of the entire Restore formula.
Exude — Beauty Dreams (Evening Formula): the overnight repair window
34 active ingredients targeting the 10pm to 2am biological window. The full ingredient rationale is detailed in the product description — here are the ingredients unique to the evening formula or used for a different purpose overnight.
Quercetin
A flavonoid with both antioxidant and senolytic properties. It targets senescent skin cells — cells that have stopped dividing but remain metabolically active and secrete inflammatory signals (the senescence-associated secretory phenotype) that degrade surrounding collagen and accelerate skin ageing. Quercetin also supports the expression of genes involved in skin barrier formation and reduces the overnight inflammatory burden that prevents collagen repair.
Chamomile Extract
Apigenin — chamomile's primary active compound — binds GABA-A receptors in the central nervous system, reducing sleep onset time and increasing slow-wave sleep duration. Slow-wave (deep) sleep is the stage where growth hormone release peaks and the most intensive skin repair occurs. A longer slow-wave sleep window means a longer, more productive overnight skin repair window. This is not a relaxation ingredient. It is a sleep architecture ingredient.
Cholecalciferol (Vitamin D3)
Regulates skin cell differentiation — the rate at which basal skin cells mature, migrate to the surface and are shed. D3 deficiency is extremely common in UK women and is directly associated with accelerated skin ageing, impaired barrier function and increased inflammatory skin responses. Taken in the evening to complement overnight cellular renewal processes.
Copper Bisglycinate
Activates lysyl oxidase — the enzyme that crosslinks collagen and elastin into structurally sound, mature tissue. Without copper, collagen fibres are synthesised but not properly assembled. Copper bisglycinate is the most bioavailable copper form. This is the ingredient that takes collagen from synthesis to structure.
Ferrous Bisglycinate
The most bioavailable iron form. Supports oxygen delivery to skin tissue during overnight repair — iron is a component of haemoglobin and myoglobin, both of which are essential for the oxygen-dependent repair processes active during sleep.
The clinical credential behind the system
The SRX Beauty Protocol was designed by Saima Rashid — a Clinical Pharmacist with postgraduate qualifications in Skin Therapeutics, Medical Aesthetics and Women's Hormonal Health and over 20 years in clinical practice.
The clinical specialism matters because skin therapeutics as a pharmacist discipline requires understanding the biochemistry of skin production, not just skin surface chemistry. That is the difference between formulating a supplement that supports the biological processes that produce skin, and formulating one that contains ingredients that are associated with skin health in the general population.
The SRX Beauty Protocol is designed around the former.
