St. Croix Products Peptide Blast Red Light Therapy Activation Serum — 1 oz, Fast-Absorbing with Peptides & Hyaluronic Acid

St. Croix Peptide Blast is a lightweight pre-treatment serum designed to prep skin for red light therapy by delivering peptides, hyaluronic acid, and antioxidants deeply and quickly.

Peptide Blast pairs a fast-absorbing, watery texture with penetration-enhancing technology to help active ingredients reach deeper skin layers so they can complement red light sessions. Formulated with six targeted peptides, green tea extract, and hyaluronic acid, this 1 oz serum is intended to hydrate, soothe, and support the appearance of firmness and smoothness without leaving residue that could interfere with device performance.

How does this serum prepare skin for red light therapy?

The formula uses safe penetration enhancers and a low-viscosity base so peptides and humectants absorb rapidly, minimizing surface buildup that might reflect or block light. That makes it suitable to apply before in-home or professional red light treatments.

• Water-like consistency that vanishes on contact
• Penetration technology to help actives reach deeper layers
• No greasy film to interfere with light exposure

Which active ingredients are included and what do they do?

Peptide Blast combines six peptides with green tea and hyaluronic acid to target hydration, antioxidant support, and the visual signs of skin texture. Each ingredient contributes to an overall supportive environment for treatments and daily skincare routines.

• Six peptides to support skin resilience and surface smoothness
• Hyaluronic acid for immediate hydration and plumping effect
• Green tea extract as an antioxidant to help calm and protect

Will this serum feel heavy or leave residue before treatment?

No — it’s engineered to be lightweight and fast-absorbing so you won’t get stickiness, shine, or a tacky film. That texture is key for layering under devices or makeup while maintaining effective ingredient delivery.

• Fast absorption suitable for pre-treatment use
• Non-greasy finish that layers well with other products
• Formulated to avoid interference with light penetration

Where is this product made and who developed it?

Peptide Blast was developed and manufactured in Oakdale, Minnesota, by a father-son formulation team working within the St. Croix Products brand. Production focuses on consistent batches and practical performance for light-assisted skincare routines.

• Designed and produced in Oakdale, MN
• Small-team formulation with quality oversight
• Packaged in a 1 oz serum bottle for targeted application

Who is this for: Peptide Blast suits people who use red light therapy at home or in-clinic and want a prep product that hydrates, supports peptide delivery, and minimizes surface residue. It’s also a practical choice for anyone seeking a fast-absorbing serum with peptides, hyaluronic acid, and antioxidant botanicals to include in a layering routine that won’t feel heavy or sticky.
