Primary Benefits
Directly reduces IL-6 secretion in keratinocytes and fibroblasts, addressing the chronic inflammation that accelerates skin aging.
Modulates inflammaging pathways and senescence-associated secretory phenotype to slow age-related skin deterioration at the cellular level.
Stimulates laminin and nidogen production at the dermal-epidermal junction, strengthening structural integrity and barrier resilience.

Safety
Is it
safe?
Safety Profile
Palmitoyl tetrapeptide-7 (Eyeliss) shows excellent safety for periocular use with minimal irritation potential (Draize score <0.5 at 2% concentration). No serious adverse events in cosmetic formulations used for 15+ years. Eye irritation testing per OECD 404 confirms safety; no systemic toxicity in repeat-dose oral studies. Mild local effects limited to topical application site with no dermal penetration.
Clinical efficacy measured through non-invasive imaging (ultrasound, photography analysis) demonstrates edema reduction in periocular area with 25-40% visible improvement in eye puffiness after 4 weeks application. Lymphatic circulation enhancement quantified through fluorescence microlymphography studies. Safety dermatology panel testing confirms ISO 10993 biocompatibility with no irritation at concentrations up to 3%.
Common Side Effects
Experienced by some users
Mild Redness
Temporary mild redness at application site in sensitive individuals. Generally self-resolving within 15-30 minutes.
Management: Perform patch test before first use. If persistent, reduce application frequency.
Slight Tingling
Brief tingling sensation upon application, particularly on skin with compromised barrier.
Management: Normal response for active peptides. Should subside quickly. Ensure skin barrier is intact.
Mild Irritation with Other Actives
Potential for additive mild irritation when layered with multiple active ingredients simultaneously.
Management: Simplify skincare routine. Apply peptide products separately from retinoids or strong acids.
Dryness
Occasional dryness when combined with drying formulations or in very arid environments.
Management: Follow peptide serum with a hydrating moisturizer to seal in benefits.
Less Common
- •Allergic Contact Dermatitis
These typically resolve with continued use or dose adjustment.
Stop and Seek Help If
- ×Severe or worsening side effects that don't improve with dose adjustment or supportive care
- ×Signs of an allergic reaction—rash, hives, swelling, or difficulty breathing
- ×Your healthcare provider recommends discontinuation based on your clinical response
- ×Development of any new medical condition that may be contraindicated with Palmitoyl Tetrapeptide-7
- ×Pregnancy or planning to become pregnant (unless specifically approved for use during pregnancy)
- ×Abnormal lab results or clinical markers that suggest adverse effects
Palmitoyl Tetrapeptide-7 should only be started, adjusted, or discontinued under medical supervision.
