Parfum (synthetic fragrance blend) is present in a leave-on retinol product that sits on skin for 8 or more hours overnight. Retinol increases skin permeability, which means fragrance allergens penetrate more deeply and remain in contact with skin longer than in a rinse-off or fragrance-free product. Parfum is a single entry that can contain hundreds of individual compounds; EU Regulation 1223/2009 Annex III requires that individual fragrance allergens present above 0.001% in leave-on products be named separately. Listing only 'Parfum' does not meet that disclosure standard. CI 16035 (Allura Red azo dye) and CI 45380 (a fluorescein derivative dye) are both contact allergens with no therapeutic function in a retinol night treatment. The retinol concentration is not disclosed; below about 0.025%, retinol is generally considered sub-functional, which would make the retinoid claim difficult to substantiate. Dimethicone and Cetearyl Alcohol are well-tolerated emollients with no safety concerns.

Retinol is the most robustly evidenced retinoid for stimulating collagen, reducing fine lines, and accelerating cell turnover. The gel-creme base with Cetearyl Alcohol, Cetearyl Glucoside, and Dimethicone provides suitable emollient and occlusive support for overnight use. The undisclosed retinol concentration is a significant gap: without knowing the dose, there is no way to assess whether the retinoid is present at a level that can deliver the anti-ageing results the product claims. Parfum introduces an inflammatory risk that compounds over the full overnight contact period, working against the skin renewal retinol is intended to support. The two azo dyes add no formulation benefit.

The full INCI list is published on the product page. Retinol concentration is not disclosed - this is the most important number in this product, and without it consumers cannot judge whether the retinoid is present at a dose that does anything meaningful. Parfum is listed as a single entry without a breakdown of individual allergen components, which does not meet the EU Regulation 1223/2009 Annex III requirement for named allergen disclosure in leave-on products. The two azo dyes are present with no explanation of their role in product marketing. The product does not carry a pregnancy warning, despite containing a retinoid ingredient - retinoids are universally contraindicated during pregnancy. No clinical study data has been published for this formula.

Pilgrim is PETA-certified cruelty-free. The brand does not sell into markets that require mandatory animal testing. Parfum and two synthetic azo dyes all appear on the COSMOS prohibited ingredients list, meaning this product would not qualify for any natural cosmetics certification. Dimethicone (silicone) is similarly COSMOS-prohibited. The formula has not been verified as vegan due to ingredient complexity.
