Niacinamide 5% Restorative Serum
$48.00
The heart of The TRNR Method™. The moment compromised skin begins to regain clarity, calm, and resilience.
A dermatologist-formulated serum for skin compromised by stress, hormones, over-treatment, and the cumulative demands of a high-performance life.
Powered by 5% niacinamide to refine tone and texture, bakuchiol to smooth without added disruption, copaiba to support visible calm, and a restorative recovery complex to replenish hydration and barrier comfort.
Skin feels more hydrated, comfortable, and supported from the first application. With continued use, the complexion appears smoother, stronger, steadier, and visibly restored.

Most serums are designed to treat compromised skin.
This one was designed to change the conditions that keep it compromised.
Because compromised skin cannot recover through alone. It must first be given the biological conditions in which recovery becomes possible: greater barrier integrity, a more supported skin ecosystem.
This is what makes the formula exceptional. It does not simply address what compromised skin looks like. It addresses what keeps it compromised.
Not a promise. A restorative sequence.
FROM THE FIRST APPLICATION
Skin feels more hydrated, more comfortable, softer, and less visibly strained. The complexion begins to look less depleted as moisture is replenished where compromised skin tends to lose it first.
WITH CONTINUED USE
Skin appears calmer, clearer, smoother, and more even. The look of pores, rough texture, dehydration, visible redness, and post-breakout discoloration is improved. Over time, the complexion begins to appear stronger, steadier, and more in balance.
Niacinamide 5%
Chosen to support ceramide production while visibly improving tone, texture, pores, redness, and post-breakout discoloration.
Bakuchiol
A sophisticated retinol alternative selected for skin that requires visible refinement without additional disruption.
Copaiba
Included for its relevance to the CB2 stress-response pathway, helping address the inflammatory pressure that keeps compromised skin visibly unsettled.
Paeonia Albiflora Root
A key part of the formula’s broader brightening architecture for skin dealing with uneven tone and lingering discoloration.
Leuconostoc Radish Root Ferment Filtrate
A ferment that protects the formula while supporting the skin ecosystem with postbiotic intelligence.
Reishi Mushroom
Adaptogenic support for skin that appears chronically overwhelmed.
Hyaluronic Acid + Sodium PCA + Glycerin
A multi-layer hydration system for skin that loses moisture faster than it can retain it.
Licorice Root
Additional brightening support for skin marked by the visible aftereffects of inflammation.
Avocado Oil + Phospholipids + Lecithin
A lipid comfort layer to help replenish what a compromised barrier chronically lacks.
Willow Bark + Mastic Gum
Clarifying support for skin that appears to have large pores, shiny, or out of balance.
Niacinamide at 5% was chosen because it is a concentration capable of meaningful visible work on tone, texture, pores, redness, and post-breakout discoloration, while remaining precisely calibrated for skin already under biological pressure.
This is the distinction at the heart of TRNR: visible efficacy, defined by precision. Clinical performance, delivered with intention.
THE FORMULATION INTELLIGENCE
Dr. Ryan Turner is a board-certified dermatologist who studied biochemistry and molecular biology. That dual training shapes not only how he reads skin, but how he formulates for it.
He does not formulate from ingredient convention, but from the biological mechanisms compromised skin is struggling to regulate.
Where conventional skincare often begins with familiar actives and category precedent, this formula begins elsewhere: with the pathways compromised skin relies upon for barrier integrity, microbiome resilience, and visible recovery.
The result is a serum that pairs established dermatological actives with less conventional compounds chosen for a clear clinical reason: CB2-pathway modulation, dual-pathway brightening support, postbiotic delivery through the preservation system, and adaptogenic recovery support for skin under chronic inflammatory pressure.
“I started with a question I had been asking for fifteen years: what does compromised skin actually need at a biological level that the standard approach was never providing? Each ingredient in this serum reflects a specific clinical observation about what compromised skin lacks, what it cannot comfortably tolerate, and what conventional formulas may not address.”

Apply moisturizer to replenish the barrier, support the microbiome, and allow restoration to become more resilient and more self-sustaining over time.
Finish each morning with SPF. What is being restored must also be reinforced to remain resilient against daily UV exposure.

Most serums are designed to treat compromised skin. This one was designed to change the conditions that keep it compromised.
Because compromised skin cannot recover through alone. It must first be given the biological conditions in which recovery becomes possible: greater barrier integrity, a more supported skin ecosystem.
This is what makes the formula exceptional. It does not simply address what compromised skin looks like. It addresses what keeps it compromised.

Your skin did not become difficult. It became compromised.
There is a point at which skin no longer responds the way it once did. It looks more reactive. More depleted. More visibly unsettled. Products that once felt effective begin to feel excessive. Redness lingers. Dehydration becomes harder to correct. Marks remain visible longer than they should. The complexion no longer appears as resilient, as even, or as calm as it once did.
At TRNR, that condition is named plainly: compromised skin.
Not a skin type. A biological state. One shaped by elevated cortisol, hormonal change, progressive microbiome disruption, barrier decline, and the accumulated cost of formulas that were never designed for skin under this kind of pressure.
“Compromised skin is not a skin type. It is what cortisol, hormones, over-treatment, and time create. This is the serum Dr. Turner built for that exact biology.”
THE FOUR ELEMENTS OF RESTORE
THE SCIENCE
Four levels of clinical restoration.
Because compromised skin is never a single-cause condition.
Compromised skin does not fall out of balance through a single mechanism, nor is it restored through one alone.
This formula was designed to address multiple biological pressures simultaneously, with ingredients selected for their relevance to the way compromised skin actually behaves.
01 | THE CB2 PATHWAY
Stress-response inflammation: Copaiba
Compromised skin often exists in a state of chronic, low-grade inflammatory pressure, driven by cortisol, amplified by barrier decline, and insufficiently addressed by standard anti-inflammatory approaches.
Copaiba was chosen for its concentration of beta-caryophyllene, a compound known to engage the CB2 pathway in skin. Rather than simply quieting visible inflammation, it helps support the stress-response mechanism contributing to it.
Visible effect: skin that appears calmer, less reactive, and more settled over time.
02 | THE DUAL BRIGHTENING PATHWAY
Why single-mechanism brightening is often not enough: Paeonia Albiflora Root + Niacinamide 5% + Licorice Root
Most brightening serums focus on one mechanism. For compromised skin, particularly skin vulnerable to post-inflammatory discoloration, that is often insufficient.
Here, niacinamide works alongside paeonia albiflora root and licorice root to address visible unevenness through a broader biological approach. The result is a formula better suited to the complexity of lingering marks and tone irregularity driven by inflammation.
Visible effect: skin that appears more even, more clarified, and less marked by the visible aftereffects of breakouts and irritation.
03 | THE LIVING FORMULA
A preservation system that also supports the skin ecosystem: Leuconostoc Radish Root Ferment Filtrate
Most preservation systems are designed solely to protect the formula. This one was chosen to do more.
Leuconostoc radish root ferment filtrate helps preserve the formula while delivering postbiotic metabolites to the skin ecosystem itself. That distinction matters profoundly for skin whose microbiome has been progressively disrupted by years of aggressive products.
This is not simply a technical choice. It is a philosophical one: a formula for compromised skin should support biological intelligence, not work against it.
Visible effect: skin that feels more supported, less over-stripped, and better able to recover over time.
04 | THE RESTORATION ARCHITECTURE
Multiple levels of support, working at once: Niacinamide 5% + Bakuchiol + Hyaluronic Acid + Recovery Complex
Niacinamide at 5% was chosen to support ceramide production while visibly improving tone, texture, pores, redness, and post-breakout discoloration.
Bakuchiol was chosen as a gentle alternative to retinol for a clinical reason: skin that is barrier-compromised, reactive, or in recovery often cannot comfortably tolerate additional disruption.
Hyaluronic acid, sodium PCA, glycerin, and propanediol replenish hydration where compromised skin loses it first. Reishi mushroom, lipids, and the wider recovery complex provide support for skin that appears depleted, shiny, congested, uneven, or chronically unsettled.
Visible effect: skin that appears fuller, smoother, more comfortable, and more visibly restored.
