Palmitoyl Tripeptide-1

Snap-8

starting

3% solution in formulation

Once daily

4 weeks initial trial

Start with a lower concentration to test your skin's tolerance. Apply to clean, dry skin in the evening. Most people see initial smoothing effects within 2-4 weeks at this level.

standard

5% solution in formulation

Once to twice daily

Ongoing use

The most commonly used concentration in commercial products. Apply morning and/or evening after cleansing. Clinical studies showing 63% wrinkle reduction used concentrations in this range.

advanced

10% solution in formulation

Once to twice daily

Ongoing use

Maximum concentration for intensive treatment. Best for stubborn expression lines or as a targeted treatment for specific areas like crow's feet or the '11' lines between eyebrows.

Snap-8

Expression Line Fighters

If you've noticed those lines that form when you smile, frown, or squint are starting to stick around even when your face is relaxed, Snap-8 is designed exactly for this. It works on the muscle-skin connection that creates these dynamic wrinkles.

Botox-Curious but Needle-Shy

Love the idea of smoother skin but not ready for injections? Snap-8 offers a topical alternative that works through a similar mechanism as Botox—just gentler and without the commitment. Perfect for testing the waters of muscle-relaxing anti-aging.

Prevention-Focused Millennials

Starting in your late 20s or early 30s with preventive skincare? Snap-8 can help keep expression lines from becoming permanent fixtures by calming the repetitive muscle movements that eventually etch wrinkles into your skin.

Sensitive Skin Types

Unlike some anti-aging actives that can be harsh, Snap-8 is remarkably well-tolerated. If retinoids make your skin angry or acids cause irritation, peptides like Snap-8 offer effective anti-aging without the drama.
