The best peptides for the skin: GHK-Cu for collagen, Glutathione for radiance, Matrixyl for wrinkles. Mechanisms, application and expected results.

Which Peptides Improve the Skin?

Dermal peptides represent one of the fastest-growing areas in cosmeceutical research. Unlike conventional creams, peptides act at the cellular level, stimulating regeneration processes that decline with age.

GHK-Cu: The King of Dermal Peptides

GHK-Cu (copper glycyl-L-histidyl-L-lysine) is the most researched peptide for skin rejuvenation.

What Does GHK-Cu Do for Skin?

• Stimulates collagen: Increases production of type I and III collagen
• Increases elastin: Improves skin elasticity and firmness
• Promotes glycosaminoglycans: Deep hydration from within
• Antioxidant: Protects against damage from free radicals and UV rays
• Anti-inflammatory: Reduces redness and skin sensitivity
• Wound healing: Accelerates the repair of wounds and scars

Documented Results

Studies show that GHK-Cu:

• Increases collagen density comparable to retinol, without irritation
• Reduces the depth of fine wrinkles in 4-8 weeks
• Improves skin texture and tone uniformity
• Accelerates post-procedure recovery (microneedling, laser)

Glutathione: The Master Antioxidant

Glutathione is the most abundant antioxidant in the body and has significant skin benefits.

Benefits for the Skin

• Clearance: Inhibits tyrosinase, reducing hyperpigmentation
• Detoxification: Neutralizes toxins that accelerate aging
• UV protection: Reduces accumulated sun damage
• Brightness: Produces a healthy glow from within

Matrixyl: The Collagen Stimulator

Matrixyl is a synthetic peptide specifically designed to stimulate type IV collagen production.

Mechanism

• Sends "repair" signals to the fibroblasts
• Fibroblasts increase the production of collagen and fibronectin
• Result: firmer skin, visible reduction of wrinkles

GLOW: The Regenerative Bundle

GLOW combines GHK-Cu 50mg + BPC-157 10mg + TB-500 10mg for a comprehensive approach to skin regeneration.

Why Combine?

The combination addresses multiple aging mechanisms simultaneously.

Melanotan I vs Melanotan II for Tanning

If your interest is tanning:

• Melanotan I (Afamelanotide): More selective, fewer side effects
• Melanotan II: More potent but with more side effects (nausea, facial flushing)

Topical or Injectable?

Topical GHK-Cu

• Concentration: 1-3% in serum or cream
• Advantage: Easy application, no needles
• Limitation: Limited penetration through the skin barrier

GHK-Cu Injectable

• Concentration: 1-2 mg subcutaneous
• Advantage: Complete absorption, systemic effect
• Limitation: Requires injection technique

Hair/Facial Mesotherapy

• Direct microinjections into the target area
• Maximum local concentration
• Requires a trained professional

Peptide Routine for the Skin

Basic Protocol

1. Cleansing con pH neutro
2. GHK-Cu serum (1-3%) — mañana y noche
3. Oral or IV glutathione — según protocolo
4. Sunscreen SPF 50+ (always)

Advanced Protocol
