What kind of evidence supports Whisper?+
Whisper is informed by published research on its individual cosmetic actives, including Argireline, GHK-Cu, SNAP-8, Leuphasyl, ectoine, and hyaluronic acid.
The evidence supports the ingredient strategy. It does not make Whisper a drug or a clinical treatment, and it should not be read as finished-product clinical testing.
Ingredient context and current formula details are summarized on this page and in the Journal.
What is the full INCI list for Selfore Whisper?+
Aqua, Pentylene Glycol, Acetyl Hexapeptide-8, Panthenol, Acetyl Octapeptide-3, Pentapeptide-18, Glycerin, Copper Tripeptide-1, Ectoine, Phenoxyethanol, Sodium Hyaluronate, Beta-Glucan, Ethylhexylglycerin, Tocopherol, Sodium Phytate, Xanthan Gum, BHT, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Citric Acid, Sodium Hydroxide.
What percentage of Argireline is in Whisper?+
8.00% w/w. Argireline (acetyl hexapeptide-8) is loaded at the upper bound of published research concentrations, which span roughly 5% to 10% in the peer-reviewed cosmetic literature.
Is the 1% copper peptide in Whisper a true 1% peptide?+
Yes. The 1% figure refers to the active GHK-Cu peptide content in the formula - the molecule itself - not a 1% dilution of a pre-formulated copper peptide complex. This is the upper bound of published research concentrations for GHK-Cu in cosmetic use. The vivid blue color of the serum is the copper ion bound to the peptide; no dye is added.
Why is Whisper blue?+
The blue color is produced by GHK-Cu (copper tripeptide-1) at 1%. The copper ion in the peptide complex has a natural blue chromophore. The intensity of the color is a rough visual indicator that the copper peptide is present at the labeled concentration. Whisper contains no added dye.
What is the pH of Whisper?+
5.5 to 5.8. This range is chosen specifically to maintain peptide stability while sitting close to the skin's natural surface pH.
Does Whisper contain parabens, sulfates, or PEGs?+
No to all three. Preservation is provided by phenoxyethanol (0.80%) and ethylhexylglycerin (0.30%), a fragrance-free preservation system. Whisper contains no sulfates (irrelevant to a leave-on serum, but worth stating) and no PEG-derived ingredients.
Why is sodium phytate used instead of EDTA?+
Standard EDTA chelators would bind the copper in GHK-Cu and undermine the active. Sodium phytate is a copper-sparing chelator, and is the formulation-correct choice for a copper-peptide serum.
Is the ectoine in Whisper synthetic or naturally derived?+
The ectoine in Whisper is biotechnologically produced - fermented from halophilic bacteria, the natural source of the molecule. It is identical to the ectoine produced in nature.
Is Whisper formulated in Canada?+
Yes. Whisper is formulated and manufactured in Canada with cosmetic GMP controls.
What molecular weights of hyaluronic acid does Whisper use?+
Two: high molecular weight at 1.0-1.5 MDa (loaded at 0.30%) for surface hydration and film, and low molecular weight at approximately 50 kDa (loaded at 0.20%) for deeper hydration.
Is Whisper vegan and cruelty-free?+
Yes. Whisper contains no animal-derived ingredients and is not tested on animals at any stage of formulation or production.
Are there allergens in the Whisper formulation?+
Whisper contains no added fragrance and is free of the 26 fragrance allergens disclosed under EU Cosmetic Regulation. The formula contains oat-derived beta-glucan; readers with severe oat allergies should patch-test.
