Why customers choose Oseila Beauty

After a red light therapy session, your skin is primed to receive active ingredients. St. Croix Peptide Blast Post-Treatment Serum delivers a concentrated blend of six peptides, green tea, and hyaluronic acid in a lightweight, fast-absorbing formula designed to prep and hydrate for enhanced visible results.

Why this serum fits a post-treatment routine

  • Maximize results post-treatment: skin often feels receptive to actives, making this the ideal moment to deliver peptides and hydrators for amplified benefits.
  • Advanced marine extract: powered by a next-generation microalgae complex that helps reinforce the skin barrier and maintain a refreshed look.
  • Deep hydration complex: high levels of sodium polyglutamate and hyaluronic acid help skin retain moisture for a visibly plump, smooth feel.
  • Comforting botanical base: aloe and allantoin provide a refreshing layer of care to leave skin feeling calm, soft, and replenished.
  • Lightweight science: safe penetration enhancers enable peptides and hydrators to reach deeper skin layers for rapid, residue-free absorption.

What’s inside and how it helps

  • Six-peptide complex: a concentrated blend designed to support visible texture and tone when used after treatment.
  • Marine extract: a next-generation microalgae complex that complements the skin’s surface and helps refresh the overall appearance.
  • Hydration power: sodium polyglutamate and hyaluronic acid work together to help skin feel moisturized and supple.
  • Soothing botanicals: aloe and allantoin contribute calming comfort to stressed-looking skin.
  • Gentle delivery: a water-based formula that absorbs quickly without a heavy residue.

How to use

  • Apply 1–2 pumps to the face and neck after red light therapy.
  • Gently press and pat until fully absorbed.
  • Follow with your moisturizer or sunscreen as part of your routine.
