BOOST provides daily dermal nutrition to support collagen production and quality, hydration, and visible skin radiance. Taken monthly, RESET helps reduce age-related cellular burden that can disrupt collagen structure—supporting firmer, healthier-looking skin over time.
Monthly reset to reduce collagen-breaking pressure from senescent cell signals
Supports collagen quality and visible firmness over time
Deep hydration and skin-barrier support to reduce moisture loss (TEWL)
Supports skin recovery and helps optimise post-treatment renewal
Two steps. One inside-out skin longevity routine.
DUO combines a monthly senescence reset with daily dermal nutrition to address the two biggest drivers of visible skin ageing: excess collagen breakdown and sub-optimal rebuilding—from within.
RESET is a short, 2-day monthly pulse of complementary flavonoids—fisetin, quercetin (Quercefit®), and luteolin—designed to help lower this background burden while remaining supportive of healthy cells.
Why a pulse, not daily?
Emerging senescence research points toward brief, periodic use rather than continuous dosing—helping reduce unwanted signaling without disrupting normal cellular function.
BOOST delivers daily dermal nutrition from within, supporting the conditions fibroblasts need to build strong, well-organised collagen and maintain a calmer baseline over time.
Collagen quality & firmness support: vitamin C + zinc, SkinAx²® complex, and matrix fractions (REGGENERATE™)
Deep hydration & barrier reinforcement: oral hyaluronic acid and ceramides to help retain moisture and support skin comfort
Antioxidant & microcirculation support: polyphenols/SOD and carotenoids (including astaxanthin) to support a more even-looking tone
BOOST (daily AM)
Take 2 capsules every morning, with or without food.
Many people take BOOST alongside their morning skincare to build a consistent routine.
RESET (monthly)
Once per month, take 4 capsules per day for 2 consecutive days. (2 in the morning, 2 in the evening).
Avoid RESET within ±5 days of in-office aesthetic treatments.
Good to know
• Stay well hydrated on RESET days
• Avoid alcohol during the pulse
• BOOST contains egg (REGGENERATE™)
General
Adults only. If pregnant, nursing, or taking prescription medication, consult your clinician.
Why these two together
BOOST supplies daily nutrition that supports collagen, elasticity, hydration, and antioxidant defense. RESET helps clear monthly cellular roadblocks linked to collagen breakdown, so results build over time.
BOOST — Daily AM
Serving size (per day): 2 capsules
REGGENERATE™ Eggshell Membrane — 300 mg
Supports elasticity and barrier function (TEWL reduction reported in human data). Allergen: egg.
SkinAx²™ Lift — 200 mg
Polyphenol-rich grape & melon complex to support radiance, texture, and collagen defense against everyday oxidative stress.
Hyaluronic Acid (≈80 kDa) — 120 mg
Helps bind water within the skin for sustained hydration and improved elasticity over time.
Ceramides — 30 mg
Replenishes skin lipids to strengthen the surface barrier and reduce transepidermal water loss (TEWL).
Astaxanthin — 6 mg
Carotenoid antioxidant supporting the skin’s antioxidant defenses against daily stressors.
Vitamin C — 80 mg
Collagen co-factor; contributes to normal collagen formation and protection of cells from oxidative stress.
Why it lasts
Working in the viable epidermis and dermis, BOOST supports renewal cycles, ongoing collagen maintenance, hydration dynamics, and barrier performance—so improvements accumulate with daily use and complement surface care.

RESET — Monthly 2-day pulse
Serving size (per pulse day): 4 capsules (2 AM + 2 PM)
Fisetin— 1,000 mg
Designed to support the body’s natural clearance of aging (senescent) cells and ease background cellular stress.
Quercetin (Quercefit® phytosome) — 500 mg
Complements fisetin across senescence-related pathways; phytosome form improves absorption vs standard quercetin.
Luteolin — 125 mg
Supports balanced inflammatory signaling and antioxidant defenses; known to cross the blood–brain barrier.
Black Pepper Extract — 25 mg
Included at a low dose to support polyphenol uptake during the 2-day pulse.
Why three flavonoids?
Broader pathway coverage in a short, high-impact cadence—aimed at what’s old while remaining healthy-cell-friendly.

Skin aging from within: collagen declines as senescent cells rise
From your 20s onward, collagen declines while senescent (“aging”) cells accumulate in the dermis — driving lines, rough texture, and loss of firmness. Topicals work mainly at the surface, but deeper changes happen inside.
How DUO helps from within: BOOST provides daily dermal nutrition for collagen strength and deep hydration. RESET delivers a short monthly clean-up to help quiet senescence signals linked to collagen breakdown.
Two steps. One deeper skin-renewal routine.
How BOOST + RESET support 6 visible signs of skin aging
Collagen renewal over time
Daily BOOST supplies dermal nutrients that support collagen and elastic-fiber renewal, while monthly RESET helps clear lingering senescent cells that disrupt skin structure.
Together, they drive deeper skin renewal, a stronger collagen network, better hydration, and smoother texture over time. When combined with aesthetic treatments such as microneedling or laser, DUO helps optimise the internal environment where visible results are built.

ExploreDUO is an inside-out skin longevity system combining daily dermal nutrition (BOOST) with a monthly 2-day senescence reset (RESET). It supports collagen quality, hydration, and elasticity daily while periodically reducing age-related cellular signals linked to collagen breakdown.
DUO pairs BOOST (daily) and RESET (monthly) to support skin structure from within, while topical skincare works at the surface. BOOST supplies dermal nutrition for collagen quality, hydration, and barrier lipids. RESET is a senescence-focused monthly protocol that helps dial down background stress signals linked to dullness and collagen breakdown pressure. Use DUO with a simple topical routine for best results.
Topicals mainly act in the epidermis (surface barrier; faster turnover ~4–6 weeks). DUO supports the dermis—the collagen/elasticity/hyaluronan matrix that drives firmness and texture—while also benefiting the viable epidermis. Inside + outside = complementary effects. Inside + outside = complementary effects at different skin depths.
Take BOOST: 2 capsules each morning with water.RESET: take 4 capsules/day for 2 days in a row, once per month (e.g., Days 1–2). Follow the label instructions.
BOOST is taken daily, year-round. RESET is taken once per month for two consecutive days.
Duo combines daily build (BOOST) with a short monthly reset (RESET) focused on senescence. Glow & Repair is a day/night system (BOOST + RENEW) centered on daily defense and nightly autophagy-linked repair.
Choose DUO if your goal is to support collagen structure and reduce age-related breakdown signals over time — with the added benefit of helping optimise the skin environment before and after aesthetic treatments.
Choose Glow & Repair if your focus is daily skin biology — amplifying skincare by supporting hydration, barrier repair, and night-time renewal.
Senescent (“aging”) cells accumulate with age and release SASP—signals that raise background inflammatory/oxidative stress. This increases collagen-breaking pressure, contributing to dullness, laxity, and slower recovery. Duo targets both sides: build quality daily (BOOST) and periodically temper that background noise (RESET).
Senescence biology is being explored with brief, intermittent pulses rather than continuous dosing. Duo follows that emerging approach: a short 2-day protocol to target background signals while staying friendly to healthy cells.
This approach reflects how senescence-targeting compounds are typically studied: intermittent, not continuous.
Topicals work mainly at the epidermis (surface barrier). Duo supports from within—reaching the dermis, where collagen/elastic/HA networks shape firmness, texture, and resilience. Inside + outside are complementary.
UV/blue light, pollution, oxidative stress, glycation (high sugar), and stress/sleep debt. These raise collagen breakdown pressure and deplete antioxidant capacity. BOOST supports collagen conditions, hydration, and antioxidant defense each day.
Inside-out first, then topicals. AM: take BOOST, then vitamin-C/antioxidant serum → moisturizer → SPF. Monthly: run the 2-day RESET on schedule. Keep sunscreen daily.
Hydration/feel can improve in 2–4 weeks. Texture, elasticity, and firmness signals generally build over 6–12+ weeks, especially as you run the monthly reset consistently.
Results vary by age, baseline skin health, and consistency.
People seeing early signs of dullness, uneven tone, slower bounce-back, or higher lifetime exposure (sun, urban pollution, intense training) who want daily support plus a periodic clean-up.
