Why Skin Needs Every Essential Nutrient, Not Just One
Skin cells rely on the same essential nutrients as every other cell in the body: thirteen vitamins, sixteen minerals, and three essential fatty acids (Omega 3, 6, and 9). These nutrients don't work in isolation — most skin processes, including collagen production and barrier repair, require several nutrients acting together in sequence. This is why formulating with a single active ingredient, however potent, only ever addresses part of what skin needs to function.
What Are Essential Nutrients, and Why Does Skin Need Them?
"Essential" has a specific meaning in nutrition science: it refers to a nutrient the body cannot make (or synthesise) on its own and must obtain from an external source. Usually this is food, but in skincare,we can apply these nutrients topically.
Skin is the body's largest organ, made of living, active cells. Those cells carry out constant biological work: producing collagen, maintaining the barrier that keeps moisture in and irritants out, renewing themselves, and defending against oxidative stress. Every one of those processes depends on specific vitamins, minerals, or fatty acids as raw materials or functional cofactors, not as a vague "boost," but as literal, required inputs.
Essential nutrients are broken down into categories, these are vitamins, minerals and fatty acids. They all play a role in skin, the also play a role in every other organ of your body hut they also work together.
The 13 Essential Vitamins Skin Uses
Vitamin A - Signals gene expression involved in collagen production and skin cell turnover
Vitamin B1 (Thiamine) -Supports cellular energy metabolism
Vitamin B2 (Riboflavin) - Contributes to maintaining a healthy skin barrier
Vitamin B3 (Niacin) - Supports barrier function and even skin tone
Vitamin B5 (Pantothenic acid) - Involved in skin's natural moisture-retention processes
Vitamin B6 (Pyridoxine) - Involved in regulating sebum production
Vitamin B7 (Biotin) - Supports healthy skin cell structure
Vitamin B9 (Folate) -Involved in skin cell renewal
Vitamin B12 (Cobalamin) - Supports cellular metabolism in skin tissue
Vitamin C - A required cofactor for the enzymes that physically construct collagen
Vitamin D - Supports skin barrier function via vitamin D receptor activity
Vitamin E - An antioxidant that helps protect skin cells from oxidative stress
Vitamin K -Involved in skin's natural resilience
The 16 Essential Minerals Skin Uses
Minerals play a foundational, often underappreciated role in skin biology — supporting enzymatic function, hydration, and cellular vitality. The 16 essential minerals include (among others) magnesium, zinc, calcium, selenium, potassium, iodine, copper, manganese, and sodium.
Copper is a useful example of why minerals matter as much as vitamins: it's a required component of lysyl oxidase, the enzyme responsible for crosslinking collagen fibres — effectively "locking" newly built collagen into a strong structure. Without adequate copper, collagen can be produced but remains structurally weak.
Essential Fatty Acids: Omega 3, 6 and 9
Essential fatty acids are core structural components of the skin barrier — the outermost layer responsible for retaining moisture and keeping irritants out.
Omega 3 supports barrier lipid composition and skin comfort
Omega 6 is a structural component of the skin barrier's lipid layer
Omega 9, while not classified as strictly "essential" in the dietary sense, supports skin softness and barrier flexibility, and closely resembles skin's own natural sebum
Why These Nutrients Work Synergistically, Not Individually
The clearest example of nutrient synergy in skin is collagen production, which requires at least three separate nutrients, each performing a distinct, non-overlapping job:
Vitamin A signals the relevant genes to begin collagen production - the instruction phase
Vitamin C is a required cofactor for prolyl and lysyl hydroxylase, the enzymes that physically build collagen's molecular structure - the construction phase
Copper is essential for lysyl oxidase, the enzyme that crosslinks and strengthens the finished collagen structure - the reinforcement phase
Remove any one of these three nutrients, and the process is incomplete, regardless of how much of the other two is present. This is true throughout skin biology, not just in collagen synthesis: barrier repair, antioxidant defence, and cell renewal all depend on multiple nutrients working in coordinated sequence, not a single "hero ingredient."
Why We Sourced Whole-Plant Extracts Instead of Isolated Actives
Most skincare formulates around one or two isolated active ingredients. A Vitamin C serum, a niacinamide serum, a retinol cream etc and this is largely because single-active products are simpler to market and to make claims about.
But if skin genuinely needs the full range of essential nutrients to carry out its own processes, formulating around isolated actives means asking skin to do complex, multi-step biological work with only part of the toolkit.
We approached formulation differently: identifying plant and marine extracts naturally containing the highest concentrations of these essential nutrients, then combining them so a single application delivers the full spectrum skin actually requires.
Alfalfa naturally contains seven of the thirteen essential vitamins: B1, B2, B3, B5, B6, B7, B9, and K
Dulse (a red algae) is naturally rich in Vitamin A and Vitamin B12
Sunflower Seed Oil and Oat Kernel Oil supply Vitamin E and essential fatty acids (Omega 3, 6 and 9)
Jojoba Esters contribute a small direct amount of Vitamin D and Omega 9, and closely mimic skin's natural sebum
Chicory Root doesn't supply Vitamin D directly, but supports Vitamin D receptor activity — helping skin use the Vitamin D it already has
Atomised Sea Salt supplies the full spectrum of 16 essential minerals
Stable Vitamin C (Ethyl Ascorbic Acid) was added separately, since Vitamin C in its common form (ascorbic acid) oxidises rapidly and loses efficacy once a product is opened
This approach means we have been able to create a product that fully nourishes your skin, with the building blocks it needs and uses, with every application. That product is the Quintessential Moisturiser.
