💡 A leave-on antioxidant moisturizer from CIRCADIA built for anti-aging facial protocols — combining oil-soluble vitamin C (BV-OSC), Matrixyl Synthe'6 peptide, and a marine ferment exfoliation support in a single daily-use lotion.

Where this earns its place in a pro practice: BV-OSC (Tetrahexyldecyl Ascorbate) delivers the brightening and tone-correction of vitamin C without the oxidation instability that makes L-Ascorbic Acid difficult to work with in retail regimens. Layered with a targeted serum underneath, Phito-Pep 1.6 functions as the closing moisturizing step in both backbar treatment and at-home protocols — making it a natural retail extension after any anti-aging facial. The Matrixyl Synthe'6 peptide provides a visible firming and wrinkle-reduction story you can explain to clients specifically, which supports retail conversion on treatment moisturizers.

Suitable for all skin types, with particular fit for mature, dehydrated, and hyperpigmentation-concerned clients.

For practices running anti-aging protocols where the retail close needs a credible, ingredient-led moisturizer.

• Visible brightening and tone correction: Tetrahexyldecyl Ascorbate, the oil-soluble vitamin C ester, helps reduce the appearance of dark spots, hyperpigmentation, and uneven skin tone with consistent twice-daily use in this leave-on formula.
• Deep hydration and moisture retention: Panthenol, present at a functional concentration in the formula, draws moisture into the skin and helps maintain a visibly plump, hydrated appearance throughout the day — supporting comfort in dehydrated and moisture-compromised skin.
• Visibly reduced appearance of fine lines and wrinkles: Palmitoyl Tripeptide-38 (Matrixyl Synthe'6) is a peptide active recognized for visibly improving skin relief, reducing the look of deep wrinkles, and contributing to a firmer, more structured complexion with regular use.
• Refined surface texture and smoothness: Vibrio Alginolyticus Ferment Filtrate (Exo-T) supports the skin's natural surface renewal and desquamation cycle, visibly refining texture and improving skin smoothness over time.
• Multi-layer antioxidant defense: Three distinct antioxidant actives — Tetrahexyldecyl Ascorbate (vitamin C ester), Superoxide Dismutase (yeast-derived enzyme), and Helichrysum Stoechas Extract (polyphenol botanical) — work across complementary mechanisms to help protect the skin's appearance from environmental stressors associated with visible premature aging.
• Suitable for all skin types including mature and sensitive skin: The lotion's emulsion base is non-stripping and provides a comfortable, non-greasy feel. The formula is positioned for all skin types, with particular benefit for mature, dehydrated, and stressed skin presentations.

Tetrahexyldecyl Ascorbate - known as BV-OSC (Oil-Soluble Vitamin C): An oil-soluble, highly stable ester of vitamin C that penetrates the lipid-rich layers of the skin more effectively than water-soluble vitamin C forms. In a leave-on lotion, this form remains active without the oxidation instability common to L-Ascorbic Acid, providing sustained antioxidant defense against free radical damage while helping visibly brighten the appearance of uneven skin tone and reduce the look of dark spots.

Panthenol - known as Provitamin B5: A water-soluble provitamin that penetrates readily into the skin and converts to pantothenic acid, a component of the skin's natural processes. In leave-on applications, panthenol acts as a potent humectant drawing moisture into the skin, softens the feel of the skin surface, and helps maintain a comfortable, calm skin feel — making it especially valuable in formulas targeting dehydrated or stressed skin.

Palmitoyl Tripeptide-38 - known as Matrixyl Synthe'6: A synthetic peptide (the INCI name for the branded active Matrixyl Synthe'6) designed to visibly address the look of deep wrinkles and loss of firmness. Peptide actives are engineered to function at very low concentrations; this peptide is widely referenced in cosmetic formulation literature for its role in visibly improving skin relief and reducing the appearance of wrinkles by supporting the building blocks of the skin's structural matrix — including the appearance of firmer, more resilient skin.

Vibrio Alginolyticus Ferment Filtrate - known as Exo-T: A ferment filtrate derived from a microorganism native to the edges of Polynesian atolls — a high-stress marine environment. The ingredient is an exopolysaccharide that supports the skin's natural surface renewal and desquamation process, helping to refine visible texture, improve perceived smoothness, and contribute to a more even skin tone over time. Trace-effective by class, this type of biotechnology-derived ferment filtrate is engineered to deliver results at low concentrations in leave-on formulas.

Superoxide Dismutase - known as Dismutin PF (yeast-derived antioxidant enzyme): An antioxidant enzyme derived from yeast that belongs to the body's natural free-radical defense network. In leave-on skincare, topically applied Superoxide Dismutase is included as a trace-effective antioxidant active that helps support the skin's visible defense against environmental stressors associated with premature skin aging. Enzyme-based antioxidants are a distinct class from vitamin-based ones and provide complementary protection alongside Tetrahexyldecyl Ascorbate.

Helichrysum Stoechas Extract - known as Everlasting-ECO: A botanical extract from the Helichrysum (Everlasting) flower, valued in professional skincare for its polyphenol content. Polyphenol-rich plant extracts are trace-effective antioxidant actives that contribute to the formula's overall free-radical defense and support a visibly more youthful-looking complexion. It adds a botanical dimension to the antioxidant profile alongside the enzymatic (Superoxide Dismutase) and vitamin-derived (Tetrahexyldecyl Ascorbate) actives.

1. Ensure the client's face and neck have been cleansed thoroughly and any serums in the treatment protocol have been applied and allowed to absorb.
2. Dispense a small amount of the lotion onto fingertips.
3. Apply evenly over the face and neck using gentle upward smoothing strokes.
4. Avoid the delicate eye area.
5. Use morning and evening as the moisturizing step in the client's skincare protocol or home-care regimen.

Professional integration and retail moment

Because Phito-Pep 1.6 functions as the final moisturizing step, it pairs naturally with a serum protocol — layer a targeted treatment serum (vitamin C or peptide serum) underneath to amplify the antioxidant and anti-aging actives. The leave-on format makes this product an ideal retail recommendation: after performing a professional anti-aging facial, reinforce the at-home protocol by explaining the specific roles of the Matrixyl Synthe'6 peptide and BV-OSC vitamin C to the client — concrete active-ingredient education increases retail conversion rates for treatment moisturizers in this category. For clients concerned about hyperpigmentation or dullness, morning application followed by SPF application on top creates a brightening plus protection stack that supports visible results between professional appointments.
