St. Croix Products Red Light Therapy Pre-Activation Serum — 1 oz, Peptides & Hyaluronic Acid for Deeper Absorption

Peptide Blast is a lightweight pre-treatment serum that primes skin to better receive red light therapy by delivering peptides, green tea, and hyaluronic acid with deep-penetration technology.

Designed to be applied immediately before red light sessions, this 1 oz serum combines six targeted peptides with antioxidant-rich green tea and moisture-binding hyaluronic acid to support smoother, more resilient-looking skin. Its water-like texture absorbs fast and uses safe penetration enhancers so actives can travel deeper without leaving residue that could interfere with device light.

How does this serum improve my red light therapy sessions?

The formula prepares the skin surface and underlying layers so red and near-infrared wavelengths can interact with more receptive tissue. By helping peptides and hydrating molecules reach deeper layers, the serum complements light exposure for more noticeable skin texture and tone benefits over time.

• Boosts skin receptivity to light through penetration support
• Delivers peptides that target elasticity and fine-line appearance
• Includes antioxidants to defend against everyday environmental stressors

What does the texture feel like and how do I use it?

Peptide Blast is watery and fast-absorbing, designed to vanish quickly so devices can sit directly on skin without slipping or blocking light. Apply 2–4 drops to clean skin, spread evenly, then begin your red light treatment once the serum feels dry to the touch.

• Water-like consistency that leaves no sticky residue
• Recommended for use right before each red light session
• Works with both at-home and professional red light devices

Which active ingredients are included and what do they do?

The formulation centers on a cocktail of six peptides plus green tea extract and hyaluronic acid. Peptides support visible firmness and texture; green tea adds antioxidant protection; hyaluronic acid attracts and retains moisture for plumping effect.

• Six peptides to support youthful-looking structure
• Green tea extract for antioxidant support
• Hyaluronic acid for immediate and lasting hydration

Is it safe for sensitive skin and how is it made?

Engineered with skin-compatible penetration enhancers and a lightweight base, the serum aims to minimize irritation while improving delivery of actives. It’s formulated and produced in Oakdale, MN by St. Croix Products' in-house team, with attention to batch quality and consistency.

• Gentle, fast-absorbing base suitable for layered routines
• Manufactured in Oakdale, Minnesota under in-house supervision
• Designed to layer under other skincare or during device sessions

Who is this for: Peptide Blast is ideal for people who regularly use red light or near-infrared devices and want a targeted serum to enhance device performance and skin hydration. It suits those seeking a residue-free, fast-absorbing pre-treatment to support the look of fine lines and texture without interfering with their light therapy routine.
