skinbetter science InterFuse Intensive Treatment LINES | Targeted Line Smoothing Serum

Deep expression lines and facial folds are different from surface fine lines. They are structural. They are caused by years of repeated muscle movement combined with volume loss and collagen decline in the deeper layers of the skin. Surface treatments rarely touch them. The skinbetter science InterFuse Intensive Treatment LINES was specifically formulated for these concerns, using patented InterFuse Technology to deliver a concentrated multi-peptide complex into precisely the locations that need it most.

This is the targeted treatment for the lines that nothing else seems to move.

Who is InterFuse Intensive Treatment LINES best for?

• Nasolabial folds (smile lines) that have become pronounced
• Deep frown lines between the brows that do not respond to standard anti-ageing serums
• Forehead lines and horizontal creases that have deepened significantly
• Those wanting a targeted topical treatment to complement or reduce the frequency of injectable treatments
• Those wanting to maintain injectable results between appointments
• Mature skin with structural line formation rather than surface fine lines only

Key ingredients and why they matter

• InterFuse Technology (patented): skinbetter science's delivery system that overcomes the skin's natural barrier to transport key ingredients more efficiently into precisely targeted areas of the skin, where concentrated peptide activity is needed to address deep lines and folds
• Concentrated multi-peptide complex: A high-potency combination of peptides that targets structural collagen support, elastin preservation and the neuromuscular mechanisms that contribute to deep expression lines simultaneously
• Hyaluronic Acid: Provides immediate plumping in the targeted areas and supports moisture retention in the skin surrounding treated lines
• Niacinamide: Supports barrier function and skin comfort throughout targeted treatment

What results can you expect?

Progressive softening of deep expression lines and folds with consistent daily use. Most users notice visible improvement in targeted areas over 8 to 12 weeks of twice-daily use. The targeted precision application concentrates the treatment exactly where it is needed.

How we use InterFuse Intensive Treatment LINES at Face for Soul

As a pharmacist prescriber who offers injectable treatments, InterFuse Intensive Treatment LINES is one of the products I most frequently recommend to patients who want to reduce the frequency of their filler or anti-wrinkle appointments without letting their results decline between sessions. Used consistently in the months between appointments, it meaningfully slows the rate at which injectable results diminish and can extend the time needed between top-ups significantly.

Complete your skinbetter science anti-ageing protocol

InterFuse Intensive Treatment LINES is a targeted add-on to rather than a replacement for your regular skinbetter science routine. Apply it to specific lines after cleansing and before your regular serum and moisturiser. For the full skinbetter science anti-ageing protocol, combine it with the AlphaRet Overnight Cream in the evening, the Alto Defense Serum in the morning and the InterFuse Treatment Cream FACE and NECK as your overall firming moisturiser.

Frequently Asked Questions

How does it compare to filler?
Filler provides immediate, significant volume correction in deep folds. InterFuse Intensive Treatment LINES works progressively over weeks to improve the structural causes of deep lines. As a prescriber who offers both, I find they work best together: filler for immediate correction, LINES to maintain and extend results and reduce the volume needed at subsequent appointments.

Where exactly should I apply it?
Apply it precisely to nasolabial folds, frown lines, forehead lines and any other deep expression lines you want to target. Use the precision tip to apply directly along each line and press gently to encourage absorption.

Is skinbetter science cruelty-free?
Yes. skinbetter science does not test on animals.

Is it vegan?
Yes. InterFuse Intensive Treatment LINES is formulated without animal-derived ingredients.

How to Use

Apply to clean, dry skin. Using the precision tip, apply directly along targeted expression lines and folds. Gently press to encourage absorption. Use twice daily before your regular serum and moisturiser.
