Editorial Identity
The GlowUp Guides Editorial Team
The GlowUp Guides Editorial Team is a collective of skincare researchers and ingredient analysts focused on translating cosmetic chemistry and dermatology research into practical, accessible guidance. Our work combines INCI-level formulation analysis, clinical evidence review, and consumer testing to evaluate products against criteria that go beyond marketing claims.
We do not hold medical credentials. We are not dermatologists. What we bring is systematic research methodology, transparent evaluation criteria, and a commitment to publishing conclusions the evidence actually supports — including when that means contradicting popular recommendations or pointing out when a product underperforms relative to its price.
GlowUp Guides content is for informational purposes only and is not a substitute for professional dermatological advice. Consult a qualified dermatologist for personal skin concerns.
How we evaluate products
Every product reviewed on GlowUp Guides is assessed against a consistent set of criteria. These are not checkbox items — they determine which products we recommend and why, and they apply regardless of brand reputation or price point.
Full INCI list review
We read the complete ingredient list in order — not a brand summary. Ingredient position indicates concentration, and we note where actives appear relative to the rest of the formula.
Active ingredient evidence
For each key active (e.g., retinol, niacinamide, AHAs, peptides), we check available clinical studies for the ingredient at the concentration range used in the formula — not just the ingredient in isolation at arbitrary doses.
Skin barrier compatibility
We assess pH range, surfactant type and gentleness, occlusive-to-humectant ratio, and whether the formula risks disrupting the skin's acid mantle — especially relevant for cleansers and exfoliants.
Formulation context
We consider ingredient interactions, delivery system (e.g., liposomal encapsulation, anhydrous base), and ingredient stability — factors that determine whether an active can reach its target and remain effective.
Target skin type specificity
We assess whether a product is genuinely formulated for its stated skin type, or whether 'all skin types' is a marketing claim unsupported by the formula. We note which skin types are likely to benefit and which may not.
Price-to-performance ratio
We compare products across price tiers against their active ingredient content, formulation quality, and documented efficacy. A higher price does not automatically indicate a better product.
Third-party certifications
Where available, we note relevant certifications such as NEA Acceptance Seal, EWG Verified, or dermatologist-tested claims — and distinguish between meaningful certifications and those with limited clinical basis.
Absence of common irritants
For products marketed for sensitive or reactive skin, we verify the absence of fragrance (synthetic and natural), denatured alcohol, essential oils, and other documented irritants at levels likely to cause reactions.
Our editorial process
From a research question to a published guide.
Research before product
Every topic starts with a question about an ingredient, mechanism, or skin concern — not with a product to feature. We review available literature and ingredient databases before writing a word.
Formulation-level analysis
We read full INCI lists, not marketing copy. Our evaluations focus on active ingredient concentration, delivery system, formulation context, and documented clinical evidence — not brand positioning.
Honest, qualified writing
We state what the evidence supports, where it falls short, and what remains uncertain. We do not exaggerate efficacy, omit caveats, or use language designed to sell rather than inform.
Review before publication
All content is reviewed against current dermatological literature before publication. We update articles when new information becomes available or when we identify areas requiring correction.
Review standard: All content published on GlowUp Guides is reviewed against current dermatological literature before publication. Articles are updated when new research becomes available, when product formulations change, or when we identify errors in prior assessments.
Sources we rely on
We prioritize primary sources and established regulatory databases over secondary reporting or brand-provided information.
- PubMed-indexed dermatology and cosmetic chemistry publications
- CosIng (EU Cosmetic Ingredient database) and established ingredient safety resources
- Manufacturer documentation, formulation white papers, and third-party product testing
- Clinical dermatology consensus documents and treatment guidelines (AAD, BAD, EADV)
- Ingredient databases including EWG Skin Deep and CosDNA for surfactant and irritancy data
