Ingredient research library
Explore the published research behind familiar skincare ingredients. Each reference below identifies what was studied and why its results cannot be assumed for a different product.
These papers did not test Turmeriq products. Ingredient form, concentration, formula and use conditions matter. This library is educational reading, not a promise of results or medical advice. Check your product label for its actual ingredients.
Turmeric/curcumin
Effects of Turmeric (Curcuma longa) on Skin Health: A Systematic Review of the Clinical Evidence
Review of heterogeneous oral/topical studies; early evidence with limitations. Educational history only. Turmeric extract in rinse-off cosmetics is not interchangeable with ingested curcumin or a studied treatment formulation.
Kojic acid
Kojic acid and combination creams in melasma
Comparative trial of 1% kojic-acid cream and combinations, including other treatments. Leave-on cream results cannot establish results for a soap, short-contact pad or unknown concentration. The study does not establish that Turmeriq products treat melasma.
Niacinamide
The effect of niacinamide on reducing cutaneous pigmentation and suppression of melanosome transfer
Mechanistic and topical formulation research. Studied concentration, vehicle and protocol differ from another finished product. The findings do not establish a percentage improvement or timeline for Turmeriq products.
Glutathione
Topical oxidized glutathione: placebo-controlled trial
2% oxidized glutathione lotion in a small trial. Oxidized GSSG is not automatically the same as the form in a Turmeriq product. The paper’s terminology is retained in its original publication; it is not a promise about skin colour.
Retinaldehyde
Retinaldehyde 0.1% and 0.05% creams: randomized controlled trial
Particular cream concentrations/protocols; relevant only to confirmed retinaldehyde, not every retinoid. Does not establish faster action, release technology or results for Turmeriq’s serum.
Hyaluronic acid
Different molecular weights of hyaluronic acid in topical formulations
Formulation-specific topical research. Its findings do not establish molecular-weight, duration or hydration performance for other masks or creams.
Vitamin C
Topical ascorbic acid on photoaged skin
Studied ascorbic acid in a particular cream. The store's Vitamin C cream lists ethyl ascorbic acid, a different form. This is background reading, not evidence of equivalent performance.
Panthenol
Topically applied dexpanthenol and epidermal barrier function
Controlled topical formulation research. The ingredient and formulation must match before relevance can be assessed. This is not a promise to repair damaged skin.
Centella asiatica
Small study of defined extract concentrations/formulations. Context for ingredient reading; not evidence of SPF, UV coverage or universal suitability.
Green tea
Cutaneous photoprotection from ultraviolet injury by green tea polyphenols
Experimental topical extract research; not a test of these sunscreen pads and not an SPF/PA rating. No SPF or PA rating can be inferred from this paper.
How to read an ingredient study
- A cell study describes a laboratory mechanism; it does not show that a finished cosmetic delivers the same effect.
- A trial of a specific cream does not establish results for a soap, pad, mask or different concentration.
- Oral or injected ingredients cannot establish the performance of a topical cosmetic.
- Ingredient research cannot establish a sunscreen’s SPF or PA rating.
