Solawave LightBoost Face & Neck Serum is a lightweight, fast-absorbing, FDA-cleared boost serum formulated to enhance Solawave Wrinkle Retreat Pro LED Face Mask and Neck & Chest Pro Light Therapy Mask treatments. Powered by the proprietary LightBoost Complex (designed to prime skin to absorb and respond to light therapy), growth factors for elasticity and firmness, multi-peptides for visibly softening fine lines and improving texture, and phyto stem cell extract for skin renewal and a refreshed, smoother look. In a study, the combination of the LightBoost ingredient and light therapy produced significantly better outcomes than light therapy alone. Apply a thin layer to clean, dry face and neck immediately before a Face Mask or Neck & Chest Pro Mask treatment, 2-3 times weekly. Can also be used independently of light therapy as a daily firming serum, AM and PM. Layer with LightBoost Face & Neck Rich Cream as a complete pre- and post-treatment routine. Suitable for all skin types including sensitive — fragrance-free, paraben-free, phthalate-free, PEG-free, vegan, cruelty-free, gluten-free, dermatologist-tested, non-comedogenic, clean formula. HSA/FSA eligible, 60-day money-back guarantee.
