The Science Behind JM Pro Clinical Skincare

My name is Jenni, and I am an Aesthetic RN with over 30 years of hands-on clinical skincare experience. Since 2020, I have been developing purpose-driven, science-based topical formulations designed to treat a variety of skin types and conditions — always with a focus on the health, integrity, and maintenance of the skin.

I became a nurse because I wanted to help people, and skincare formulation is an extension of that calling. There is a meaningful connection between how people feel about their skin and their overall sense of wellbeing. Healthy skin, however, is not just about what you apply topically — it also requires a healthy lifestyle: proper nutrition, regular exercise, stress reduction, and quality sleep. When combined with a clinically sound skincare protocol, these habits deliver the best outcomes for long-term skin health.

As a formulator with a nursing foundation, my goal is to provide simple, solutions-oriented daily skincare protocols that effectively and safely address your skin type and concerns. I am rooted in the intersection of aesthetics and scientific research, and it is my mission to create formulations that repair, nourish, protect, and maintain the integrity of our largest organ — the skin.


My Formulation Method

For me, nursing is a blend of applied science and art. I draw from the natural and formal sciences — biology, chemistry, anatomy, and physiology — and apply that knowledge to solve real skincare challenges, always with clinical rigor and patient-centered empathy.

When I begin developing a product, I always ask how an ingredient works, not just why it works. This distinction drives my critical thinking and guides me toward formulations that are both effective and safe.

Every ingredient must have a purpose. Each one must contribute to the repair, maintenance, regeneration, or protection of the skin. This is where research and science become essential — understanding the mechanism of action behind each active ingredient ensures that every product delivers on its promise.

These are the active ingredients I trust — each one chosen for its clinical evidence and its specific role in repairing, maintaining, regenerating, or protecting the skin.

Evidence-Based Practice: The Foundation of Every Formulation

JM Pro Clinical formulations are designed to be both effective and safe. Our unwavering focus is on quality of care and positive outcomes for every client.

The most important tool I bring to formulation is my Evidence-Based Practice (EBP) skillset — a cornerstone of professional nursing. EBP is a problem-solving approach to clinical decision-making that enables practitioners to provide the safest, highest-quality care. I apply this same framework to every product I develop.

My EBP Process

1. Ask
I begin by defining a clinical question and a clear goal. For example: What active substance best supports barrier function, and how can I formulate a product that delivers that benefit effectively and safely?

2. Acquire
I seek out the most current, peer-reviewed research — not personal beliefs, trends, or tradition. My primary sources include PubMed Central and established nursing and dermatology associations. The goal is to identify relevant, peer-reviewed journals and databases that confirm an ingredient's efficacy and reliability.

3. Appraise
I evaluate the validity and reliability of each study using a clinical evidence hierarchy:

Level I (Highest): Systematic reviews, meta-analyses, and clinical practice guidelines derived from multiple randomized controlled trials (RCTs). These minimize bias and provide the most definitive conclusions.
Level II: Well-designed individual RCTs, where participants are randomly assigned to intervention or control groups. RCTs reduce selection bias and establish causation, making them the gold standard for evaluating treatment efficacy.

4. Apply
I integrate the research findings with my clinical experience and expertise to guide formulation decisions.

5. Assess
I evaluate outcomes — ensuring the finished product performs as intended and supports the client's skin health goals.

the three layers of the skin

Understanding the Skin: Anatomy & Physiology

The skin is our largest living organ, and it is divided into three distinct layers:

  • epidermis
  • dermis
  • hypodermis

Together, these layers are responsible for protection and structural support, sensory perception, vitamin D synthesis, temperature regulation, and excretion.

The Epidermis

The epidermis is the outermost layer of the skin — roughly as thin as a single sheet of paper. It is composed of stratified squamous epithelial cells that are continuously produced, migrate upward, and shed from the surface. These cells begin as living, cuboidal keratinocytes at the base and progressively harden, produce keratin, lose their organelles, and flatten as they travel toward the surface. The epidermis serves as the skin's primary defense against mechanical injury, chemical exposure, microbial invasion, and dehydration.

The Five Layers of the Epidermis (deepest to outermost)

  • Stratum Basale — The deepest layer, anchored to the basement membrane. Stem cells here (keratinocytes) are cuboidal in shape and continuously divide, pushing new cells upward. These cells are responsible for producing keratin, the tough structural protein that gives skin its protective strength.
  • Stratum Spinosum — Cells are tightly bound together for structural strength and begin their upward migration.
  • Stratum Granulosum — Cells begin to flatten, lose their organelles, and produce water-resistant keratin in preparation for terminal differentiation.
  • Stratum Lucidum — Present only in thick skin, such as the palms and soles of the feet.
  • Stratum Corneum — The tough, waterproof outermost surface. Cells are fully keratinized, anucleate (no nucleus), and continuously shed.

Functions of the Epidermis

Barrier Protection

Keratinocytes produce keratin, and the surrounding extracellular lipid matrix creates a "brick and mortar" system — a waterproof barrier that keeps pathogens (bacteria, viruses, fungi), environmental toxins, UV radiation, and excess water out, while preventing transepidermal water loss (TEWL). This barrier continuously renews itself to maintain its protective integrity.

Immune Defense

Immune Defense Langerhans cells, embedded within the epidermis, are part of the skin's innate immune system. They identify and neutralize foreign invaders before they can penetrate deeper layers.

Pigmentation

Melanocytes produce melanin, which gives skin its color and acts as a natural sunscreen — absorbing UV radiation to protect keratinocyte DNA from mutagenic damage.

Vitamin D Synthesis

The epidermis initiates vitamin D production upon UV exposure. Vitamin D then moves into the extracellular space, diffuses into dermal capillaries, enters the bloodstream, and travels to the liver and kidneys for activation.

Sensory Perception

Merkel cells in the stratum basale connect to sensory nerve endings and mediate light touch. Free nerve endings throughout the epidermis detect pain, temperature, and itch.

Temperature Regulation

The epidermis facilitates evaporative cooling through sweat secretion, and assists in heat dissipation when underlying blood vessels dilate.

A note on the dermal-epidermal junction:

FUN FACT: The epidermis and dermis are connected by a basement membrane. Keratinocytes, melanocytes, and Merkel cells reside on top of this membrane. Because the epidermis is avascular (contains no blood vessels), the cells at the basement membrane are nourished by the vascular supply from the dermis below.

The Dermis

The dermis ranges from 1 to 4 mm in thickness and is composed of connective tissue — primarily collagen and elastin fibers — organized into two distinct zones:

  • Papillary Dermis (superficial): a thinner, more loosely organized layer just beneath the basement membrane
  • Reticular Dermis (deep): a denser, more fibrous layer that provides the bulk of the skin's structural strength

The role of collagen in skin function: Collagen provides structural support and overall firmness, stretch resistance that allows skin to flex without tearing, and resilience against repetitive motion — such as the repeated muscle contractions involved in facial expressions.

Functions of the Dermis

  • Structural and mechanical support
  • Elasticity and resilience
  • Nutritional supply to the epidermis (via its vascular network, delivering oxygen and nutrients and removing cellular waste)
  • Immune defense
  • Sensory perception
  • Temperature regulation (via sweat glands, sebaceous glands, and vascular control)

The primary cell of the dermis is the fibroblast, which produces collagen and elastin. The dermis also contains endothelial cells, immune cells, nerve cells, blood supply, and a lymphatic system. All of these cells reside within the extracellular matrix (ECM) — a structural scaffold composed of collagen and elastin fibers, plus a non-fibrous component called the ground substance: a viscous gel of large carbohydrate and carbohydrate-protein molecules suspended in water that supports hydration and structural integrity.


The Hypodermis

The hypodermis — also called the subcutaneous layer — is the deepest layer of the skin. Composed primarily of adipose (fat) and connective tissue, it anchors the dermis to the underlying fascia and muscle. Its primary functions include insulation and thermoregulation, structural support, shock absorption, and energy storage.

The Aging Skin: What Changes and Why

Skin aging is driven by two overlapping processes: intrinsic (chronological) aging, which is genetically programmed, and extrinsic aging, which is driven by environmental factors such as UV radiation, pollution, and lifestyle choices. Together, these processes produce measurable structural and functional changes across all three layers of the skin.

Epidermal Changes

Slower Cell Turnover

The transit time of a keratinocyte from the stratum basale to the stratum corneum increases by 10 or more days in older adults compared to younger adults, resulting in a duller, less responsive surface.

Epidermal Thinning and Atrophy

The normally undulating border between the epidermis and the papillary dermis flattens over time, reducing surface area contact between the layers. This increases shearing forces and makes the skin more fragile and prone to injury.

Compromised Barrier Function

Stratum corneum lipids decline and cholesterol synthesis decreases, leading to a rise in surface pH, increased transepidermal water loss (TEWL), dryness (xerosis), and itching (pruritus).

Decreased Immune and Pigment Cells

Both Langerhans cells and melanocytes decline in number, weakening the skin's ability to defend against pathogens and UV-induced DNA damage.

Dermal Changes

Structural Changes

Collagen loss and degradation

Structural Changes

Fibroblasts produce less collagen over time, and existing collagen fibers fragment and become disorganized — resulting in loss of structural integrity, firmness, and tensile strength. Research indicates that collagen production in sun-protected skin of adults aged 80 and older is reduced by approximately 75% compared to adults aged 18–29. (PMC)

Elastin weakening (elastosis)

Elastin fibers lose their elasticity, reducing the skin's ability to recoil after movement or deformation.

Ground substance depletion

 Hyaluronic acid and other water-binding molecules decline, reducing the dermis's capacity to retain water and resulting in volume loss and dehydration.

Cellular and Vascular Changes

Fibroblast senescence

Active dermal fibroblasts decline in number. Senescent cells stop dividing but do not die — instead, they release inflammatory mediators and matrix metalloproteinases (MMPs) that actively degrade surrounding collagen.

Flattening of the dermal-epidermal junction

 The loss of the undulating interface between the epidermis and papillary dermis increases susceptibility to mechanical shearing, blistering, and tearing.

Vascular reduction

 The number of blood vessels and capillaries decreases, and remaining vessels become more fragile — contributing to increased bruising and impaired wound healing.

A note on the broader health implications of skin aging:

Beyond aesthetics, aging skin carries real physiological risk. Increased fragility, delayed wound healing, and reduced immune surveillance create a higher susceptibility to infection, allergies, injury, and skin cancer. This is why maintaining barrier integrity and supporting the ECM are not just cosmetic goals — they are clinical ones.
