The Selfore Journal
Notes on peptides, skin rhythm, formulation, and modern care.
A quiet editorial library for reading labels, understanding actives, and building a modern peptide routine without overstatement.
Comparison
Argireline vs. Matrixyl vs. GHK-Cu
Three peptides, three mechanisms, three jobs. Why a serious peptide formula uses all three rather than betting on one — and what the research supports.
Peptide Science
Argireline vs. Botox
A careful, research-led look at Argireline, Botox, expression lines, and what topical peptides can realistically do for cosmetic skin care.
Skin Biology
Expression lines vs. static wrinkles
Learn the cosmetic difference between expression lines, static wrinkles, and fine lines, plus how to think about care for each category.
Routine
How to layer a peptide serum
A practical guide to layering peptide serum with retinoids, vitamin C, niacinamide, acids, moisturizer, and SPF without undermining the routine.
Peptide Science
Peptide stacking, explained
A formulation-minded guide to signal peptides, carrier peptides, neuropeptides, enzyme-inhibitor peptides, and why stacking mechanisms matters.
Formulation Principle
Reading a peptide serum label
How to read a peptide serum label with more confidence, including INCI order, the 1% line, disclosed concentrations, packaging, and fragrance status.
Peptide Science
What is a copper peptide?
A guide to GHK-Cu, the blue copper peptide used in cosmetic peptide serums, including what it is, why it is blue, and how it fits in skin care.
Ingredient Science
What is ectoine?
A guide to ectoine in skincare, including its role in hydration, barrier support, formulation stability, and high-active peptide care.
Formulation Principle
Why fragrance-free matters
A cautious, evidence-led guide to fragrance-free skincare, fragrance allergens, essential oils, and why high-active peptide formulas can benefit from restraint.
