Lira Clinical MYSTIQ Infused C Serum

Bestseller Lira Clinical MYSTIQ Infused C Serum — advanced vitamin C serum with glutathione, ergothioneine, CBD, and plant stem cells Size: 1 oz. Why every Lira Clinical product works differently Every Lira Clinical formula is built around three pillars: peptides that signal skin to produce collagen and renew itself, plant stem cells that protect skin's own cellular longevity at a genetic level, and probiotics that balance the skin microbiome for resilient, healthy skin. These three elements work together in every product — which is why results compound over time and why Lira Clinical products perform best when used as a system. Lira Clinical exclusive: MASQ-tech™ MASQ-tech™ is Lira Clinical’s proprietary ingredient technology derived from mastiha — a rare natural resin harvested exclusively from mastic trees on the Greek island of Chios. Used for over 2,500 years in Mediterranean medicine, it is now the cornerstone of Lira Clinical’s formulas as a skin-calming and skin-rebuilding agent. MASQ-tech™ prevents post-inflammatory hyperpigmentation (PIH), minimizes pore appearance, increases cell proliferation, and neutralizes free radicals. What it does for your skin One of the most sophisticated vitamin C serums available at any price point. The MYSTIQ Infused C leads with tetrahexyldecyl ascorbate — the most stable and deeply penetrating form of vitamin C — at a high concentration as the second ingredient, then builds an antioxidant network around it with glutathione, ergothioneine, and CBD that addresses oxidative stress through multiple pathways simultaneously. Add the resurrection plant, imperata cylindrica, dual MASQ-tech™ complex, colloidal silver and gold, orange stem cells, and two licorice root derivatives — and you have a vitamin C serum that is also a comprehensive antioxidant treatment, a brightening protocol, and a hydration serum in one formula. Key benefits Tetrahexyldecyl Ascorbate at high concentration — the most stable, most penetrating vitamin C available Three forms of vitamin C working at different depths simultaneously Glutathione — the master antioxidant that regenerates other antioxidants including vitamin C Ergothioneine — one of the most potent and stable antioxidants known, with its own cellular transporter Cannabidiol (CBD) calms inflammation while the vitamin C brightens Dual MASQ-tech™ (oil and gum) for the most complete mastic resin spectrum Orange Callus Culture Extract — plant stem cell with brightening and photoprotective properties Haberlea Rhodopensis (resurrection plant) protects against dehydration stress Colloidal silver and gold for antioxidant and cellular renewal support Stays stable — does not oxidize or turn orange Best for All skin types focused on brightening, antioxidant protection, hyperpigmentation, uneven tone, and anti-aging. Ideal as a morning serum — the antioxidant complex pairs perfectly with SPF to create a comprehensive daily defense against UV and environmental oxidative damage. Particularly valuable for clients in urban environments like Los Angeles where pollution and blue light exposure compound UV damage daily. How to use Apply 1-2 pumps to clean skin every morning before moisturizer and SPF. Press gently into skin and allow to absorb before layering. Follow immediately with Lira Clinical SPF EliōDrops 30 for a complete antioxidant and UV protection protocol. Can also be used in the evening for intensive brightening treatment. Jasmine's note “Vitamin C serums are everywhere but good ones are rare. This one stays stable, absorbs without tackling, and delivers a visible brightness over 4-6 weeks that clients notice before I even point it out. I pair it with SPF every morning and treat it as non-negotiable for any client focused on tone.” “What makes this formula genuinely different is the antioxidant network built around the vitamin C. Most serums pair vitamin C with vitamin E and call it a day. This one adds glutathione — the master antioxidant that regenerates vitamin C after it has been spent — and ergothioneine, which has its own cellular transport system that pulls it actively into skin cells. The vitamin C is working harder and lasting longer because the supporting ingredients are doing their job. That is sophisticated formulation.” Key ingredients Tetrahexyldecyl Ascorbate — listed as the second ingredient after water, indicating a meaningfully high concentration; the most stable and deeply penetrating form of vitamin C; oil-soluble so it crosses the skin barrier effectively; converts to active ascorbic acid within the skin; protects against UV oxidative damage and blue light while stimulating collagen production Glutathione — the master antioxidant produced naturally in every cell; responsible for regenerating spent antioxidants including vitamins C and E; when glutathione is depleted by oxidative stress, the entire antioxidant network collapses; topical glutathione replenishes this foundation and keeps vitamin C active longer; documented brightening effects in clinical research; rare in retail skincare at effective concentrations Ergothioneine — a naturally occurring amino acid antioxidant originally discovered in ergot fungus; unlike most antioxidants that enter cells through passive diffusion, ergothioneine has its own dedicated transporter protein (OCTN1) in human cells that actively pulls it in; one of the most stable antioxidants known — it does not degrade in the presence of other antioxidants; protects mitochondrial DNA from oxidative damage; rarely found outside pharmaceutical and advanced professional skincare Cannabidiol (CBD) — a potent anti-inflammatory and antioxidant; calms the inflammatory responses that trigger PIH and barrier disruption while the vitamin C complex does its brightening work; growing clinical research for skin calming, barrier support, and sebum regulation Ascorbyl Palmitate & Ascorbic Acid — two additional vitamin C forms that complete the three-form vitamin C system; Ascorbyl Palmitate works in the lipid layer, Ascorbic Acid provides surface antioxidant activity; together with Tetrahexyldecyl Ascorbate they cover every depth of the skin Pistacia Lentiscus (Mastic) Gum Oil + Mastic Gum (MASQ-tech™ dual complex) — both the oil and the gum form are present, delivering the most complete spectrum of mastic resin compounds in any Lira Clinical formula; prevents PIH, minimizes pores, increases cell proliferation, neutralizes free radicals Citrus Aurantium Dulcis (Orange) Callus Culture Extract — plant stem cell from orange callus tissue with brightening and photoprotective properties that work synergistically with the vitamin C complex Haberlea Rhodopensis Leaf Extract — the resurrection plant extract; protects cells from dehydration stress and oxidative aging Imperata Cylindrica Root Extract — drought-resistant grass root that draws and retains moisture deep in the skin Sodium Hyaluronate Crosspolymer — cross-linked HA that forms a long-lasting moisture film on the skin surface Colloidal Silver and Gold — antimicrobial, antioxidant, and cellular renewal support Stearyl Glycyrrhetinate + Dipotassium Glycyrrhizate — two forms of licorice root derivative; one fat-soluble and one water-soluble, together covering more of the anti-inflammatory and brightening pathway than either alone Yeast Polysaccharides + Yeast Extract — beta-glucan rich ferments for deep hydration and cellular energizing Beta Vulgaris (Beet) Root Extract — betalain antioxidants with brightening properties and betaine humectant Tocopherol + Tocopheryl Acetate — two forms of vitamin E; work synergistically with the vitamin C complex for enhanced antioxidant protection Complete your routine Apply after cleansing: Face Reality Barrier Balance Creamy Cleanser or Lira Clinical BIO Enzyme Cleanser — clean skin maximizes serum absorption Layer underneath: Lira Clinical BIO Hydra Infusion first if intensive hydration is needed, then MYSTIQ Infused C on top Seal with moisturizer: Lira Clinical BIO Lift Creme or BIO Caviar Creme — the serum penetrates deeply, the moisturizer locks in the treatment Always finish with: Lira Clinical SPF EliōDrops 30 — vitamin C and SPF together provide significantly greater photoprotection than either alone; this combination is the gold-standard morning protocol Evening pairing: Lira Clinical PRO Retinal-Plus Treatment Cream — vitamin C in the AM, retinaldehyde at night is the most comprehensive anti-aging protocol available For hyperpigmentation: Lira Clinical PRO Lite Serum in the evening alongside the MYSTIQ Infused C in the morning — morning antioxidant brightening, evening multi-pathway melanin suppression Read more: Why most vitamin C serums stop working — and why this one doesn't → Frequently asked questions What is glutathione and why does it matter in a vitamin C serum? Glutathione is the master antioxidant — the molecule that every cell in your body produces to manage oxidative stress. One of its most important roles is regenerating other antioxidants, including vitamin C and vitamin E, after they have been spent neutralizing free radicals. When glutathione is depleted, the antioxidant network collapses — vitamin C gets used up and has nothing to bring it back. Including glutathione in a vitamin C serum keeps the entire antioxidant system active longer, extending the period of protection and efficacy after application. Most vitamin C serums don't include it. This one does. What are peptides? See BLOG What is ergothioneine and why haven't I heard of it? Ergothioneine is an amino acid antioxidant that was first discovered in ergot fungus and is found in high concentrations in mushrooms. What makes it extraordinary is that human cells have a dedicated transporter protein — OCTN1 — that actively pulls ergothioneine into the cell rather than relying on passive absorption. Your body treats ergothioneine as a nutrient it needs rather than a foreign substance it tolerates. It is exceptionally stable, does not degrade in the presence of other antioxidants, and protects mitochondrial DNA from oxidative damage. It is not widely known in consumer skincare because it has primarily been used in pharmaceutical and research contexts — finding it here is a genuine indicator of how seriously Lira Clinical takes their formulation science. Will this vitamin C serum turn orange like others I've used? No — and here is why. The orange color change in vitamin C serums happens when pure L-ascorbic acid oxidizes on exposure to air and light. The primary vitamin C in this formula is tetrahexyldecyl ascorbate — an oil-soluble ester that is significantly more stable than pure ascorbic acid and does not undergo the same visible oxidation. It will not turn orange. It will not smell metallic. It will stay active from the first use to the last drop. This stability is one of the primary reasons I recommend Lira Clinical vitamin C formulas over many other options on the market. Read more about vitamin C stability → Is CBD in a skincare serum just a trend or does it actually do something? In this formula it is genuinely doing something. CBD is a documented anti-inflammatory and antioxidant — it calms the inflammatory response that can be triggered by active brightening ingredients and supports barrier function during treatment. Its inclusion here is not trend-chasing — it serves a specific function alongside the vitamin C complex. The growing clinical research on topical CBD for skin calming, barrier support, and sebum regulation is substantive. When a sophisticated brand like Lira Clinical includes it, it is because it earns its place in the formula.
