SKINCEUTICALS
Relax the look of expression lines with this skin rejuvenating formula, enhanced with unique and patented InterFuse ® delivery technology for optimal effectiveness. Formulated with peptides, vitamin C, and hyaluronic acid, this targeted formula addresses the visual impact of collagen decline and helps to provide a smoothing effect on targeted areas such as crow’s feet, forehead and smile lines.
- Dermatologist tested - Non-comedogenic - Formulated without parabens, fragrance and dyes
Directions: Apply a thin layer morning and evening on clean, dry skin to targeted areas: crow’s feet, forehead, upper lip and smile lines, as the first step. Follow with your skinbetter science regimen. Use of a sunscreen during the day is recommended.
Caution: For external use only. Discontinue if signs of irritation or rash appear. Avoid contact with eyes. If contact occurs, rinse thoroughly with water. Keep out of reach of children
Patented, state-of-the-art technology features high-molecular weight, injectable-grade hyaluronic acid for the improvement in the appearance of deep expression lines. Four additional types of hyaluronic acids of varying molecular weights work to bind water to the surface of the skin to improve moisture retention to smooth the appearance of lines and wrinkles.
Peptides help expression lines appear smoother upon application.
A collagen complex made up of amino acids, peptides and Vitamin C work synergistically to support the skin.
This targeted formula helps reduce the look of deep wrinkles and expression lines and is complementary to in-office treatments.

BeforeWhy this house
AlphaRet and Mystro rank among dermatology's most-awarded complexes. SkinBetter Science combines molecular innovation with skin tolerance.

From the House
InterFuse Lines targets deep expression lines (forehead, glabella, around the mouth) with a concentrated peptide formula. The serum texture applies locally, on identified zones, rather than as a uniform layer. Useful as a twelve-week course, ideal alongside an in-clinic protocol when patients want to extend the effect between appointments. Use as a course rather than continuously: the skin benefits from pauses to integrate the effect.
