St. Croix Products Peptide Blast Red Light Therapy Post-Treatment Serum 1 fl oz — Six Peptides & Hyaluronic Acid

Peptide Blast is a lightweight post-red-light serum that delivers a concentrated blend of six peptides, marine extract, sodium polyglutamate, and hyaluronic acid to amplify and extend visible post-treatment results.

This one-fluid-ounce serum is formulated specifically for use immediately after red light therapy sessions, when skin absorption is highest. The fast-penetrating, watery texture carries targeted peptides and a next-generation microalgae complex deeper into the skin while replenishing moisture with high levels of sodium polyglutamate and hyaluronic acid. Aloe and allantoin provide a soothing base so skin feels calm and refreshed after treatment rather than tight or sticky.

How does Peptide Blast support skin after red light therapy?

Red light therapy can temporarily increase skin permeability, creating an ideal window to deliver concentrated actives. Peptide Blast takes advantage of that period to introduce peptides and marine-derived ingredients designed to support resilience and hydration without heavy residues.

• Delivers a six-peptide complex aimed at supporting visible firmness and texture.
• Microalgae complex helps reinforce the skin’s barrier function.
• Fast-absorbing watery base ensures rapid penetration post-treatment.

Will this serum hydrate without feeling greasy?

The formula is engineered to hydrate deeply while remaining weightless on the skin. Sodium polyglutamate and hyaluronic acid attract and hold moisture at different layers, producing a plumped, smooth feel without a heavy finish.

• High-performance humectants retain moisture for immediate plumpness.
• Light texture absorbs quickly, leaving no visible residue.
• Aloe and allantoin provide calming hydration for sensitive post-treatment skin.

What makes the marine extract and peptides important here?

The marine extract is a concentrated microalgae complex that supports barrier integrity and a refreshed appearance. The six peptides are included to work synergistically with enhanced delivery, aiming to support smoother-looking skin and a more even texture over continued use.

• Next-generation microalgae helps maintain a healthy, resilient barrier.
• Peptides are selected for complementary skin-conditioning actions.
• Designed to reach deeper layers when applied after red light therapy for better active uptake.

How should I use it to get the best outcome?

Apply Peptide Blast immediately after your red light session while skin is still receptive. Use a small pump or dropper’s worth, smooth across face and neck, and follow with any recommended moisturizer or sunscreen once absorbed.

• Use right after red light therapy for maximum active delivery.
• Apply a thin, even layer to clean, dry skin and allow full absorption.
• Layer with your usual moisturizer or sunscreen after absorption if heading outdoors.

Who is this for? Peptide Blast is designed for people who regularly use red light therapy and want to enhance and extend their session results with advanced actives. It suits all skin types that tolerate post-treatment serums, especially those seeking lighter textures that deliver deep hydration, peptide support, and a marine-derived barrier booster. Avoid use if you have known sensitivities to any listed ingredients; patch-test if uncertain.
