Obagi Professional-C Peptide Complex | Vitamin C, Growth Factors and SNAP-8 Serum

Most antioxidant serums do one thing: protect. Obagi Professional-C Peptide Complex does three. Vitamin C provides antioxidant free radical protection and brightening. Plant-derived growth factors Kinetin and Zeatin support the skin barrier and address photodamage. SNAP-8 (Acetyl Octapeptide-3) targets expression lines and wrinkles at a neuromuscular level. Three of the most clinically proven anti-ageing ingredient categories in a single lightweight serum, with visible improvements in firmness, skin tone, fine lines and wrinkles in as little as one week.

For patients in Obagi programmes who want Vitamin C antioxidant protection alongside active firming and anti-wrinkle activity in a single morning serum, Professional-C Peptide Complex combines these mechanisms more comprehensively than any single-category antioxidant serum can.

Who Is It For?

• Those wanting Vitamin C antioxidant protection alongside active firming and line-reducing activity in one serum
• Fine lines, expression lines and early facial wrinkles alongside dullness and environmental damage
• Those on GLP-1 medications wanting maximum multi-mechanism anti-ageing from a single morning serum
• Those who want to simplify their morning routine without losing active coverage
• All skin types wanting a comprehensive antioxidant and anti-ageing morning serum

How Does It Work?

Tetrahexyldecyl Ascorbate, a stable oil-soluble form of Vitamin C, neutralises lipid-soluble free radicals in the membrane environment and provides brightening through antioxidant protection against UV-triggered melanocyte stimulation. Kinetin and Zeatin are plant-derived cytokinins with published evidence for reducing photodamage, supporting barrier function and improving the appearance of fine lines through growth factor-like signalling mechanisms. SNAP-8 (Acetyl Octapeptide-3) is a peptide that modulates neuromuscular communication at the skin-muscle junction, reducing the expression muscle contractions that deepen dynamic lines over time.

Key Ingredients

• Tetrahexyldecyl Ascorbate (stable Vitamin C): An oil-soluble, stable Vitamin C derivative that provides antioxidant free radical protection and brightening in a form that does not oxidise as rapidly as L-Ascorbic Acid, maintaining potency throughout the product's lifespan.
• Kinetin and Zeatin (plant growth factors): Plant-derived cytokinins clinically shown to support skin barrier function, reduce the appearance of photodamage and improve skin firmness with consistent use.
• SNAP-8 (Acetyl Octapeptide-3): An anti-ageing peptide that reduces neuromuscular communication at the expression muscle-skin junction, decreasing the micro-contractions that deepen dynamic expression lines over time. Provides a peptide-level approach to expression line reduction alongside the Vitamin C antioxidant and growth factor anti-ageing mechanisms.
• Sodium Hyaluronate: Provides hydration support alongside the active antioxidant and anti-ageing complex.

Benefits

• Visible improvement in firmness, fine lines and wrinkles in as little as one week
• Brightens and defends against free radical damage through Vitamin C
• Supports skin barrier and reduces photodamage through Kinetin and Zeatin
• Reduces expression line depth through SNAP-8 neuromuscular modulation
• Three anti-ageing mechanisms in one lightweight morning serum
• Non-comedogenic and suitable for all skin types

What Results Can You Expect?

At 1 week: visible improvement in skin tone and early fine line reduction with consistent morning and evening use. At 4 weeks: improved firmness, brightness and line depth reduction. At 3 months: significant comprehensive multi-mechanism anti-ageing improvement.

How We Use It at Face for Soul

As a pharmacist prescriber specialising in skin health, Professional-C Peptide Complex is the morning serum I recommend for patients who want multi-mechanism anti-ageing activity alongside their daily antioxidant protection in a single step. The three-mechanism approach produces breadth of results that a standalone Vitamin C serum alone does not achieve.

How to Use

Apply 2 to 3 pumps to the face morning and evening. Follow with an Obagi moisturiser and SPF in the morning.

Frequently Asked Questions

Is this instead of or as well as the Professional-C Serum?
The Peptide Complex contains a stable Vitamin C derivative rather than L-Ascorbic Acid. It provides different Vitamin C activity alongside growth factors and peptide anti-ageing. For maximum antioxidant protection, pairing the Peptide Complex with a Professional-C Serum 10% or 15% provides complementary Vitamin C mechanisms. As a standalone morning serum, the Peptide Complex provides multi-mechanism anti-ageing coverage that the L-Ascorbic Acid serums alone do not include.

Can I use it with tretinoin?
Yes. Apply in the morning. Apply tretinoin in the evening only.

Is it pregnancy safe?
No established pregnancy contraindications. Consult your midwife or obstetrician.

Does it clog pores?
No. Non-comedogenic and suitable for all skin types.

Clinical Insight

As a pharmacist prescriber, Professional-C Peptide Complex provides more multi-mechanism daily anti-ageing activity than any standalone Vitamin C serum because it adds growth factor and SNAP-8 peptide mechanisms alongside the antioxidant and brightening Vitamin C activity. For patients with concurrent firmness, line and photodamage concerns who want the most comprehensive daily single-serum coverage, it is the most appropriate product in the Professional-C range.
