Parfum (synthetic fragrance blend) is present in a leave-on retinol product that sits on skin for eight or more hours overnight. Retinol increases skin permeability, which means fragrance compounds are able to penetrate more deeply during overnight contact than they would in a fragrance-free or rinse-off context. Listing only Parfum as a single entry hides the individual fragrance chemicals present, so consumers cannot check for specific allergens they may react to. CI 16035 (Allura Red azo dye) and CI 45380 (a fluorescein derivative dye) are both contact allergens with no therapeutic role in a retinol night treatment. The retinol concentration is not disclosed. At very low concentrations, retinol delivers little practical benefit, which makes any sensitisation risk harder to justify.

Retinol is the most robustly evidenced ingredient for stimulating collagen, reducing fine lines, and accelerating cell renewal. The emollient base with Cetearyl Alcohol, Cetearyl Glucoside, and Dimethicone provides a suitable occlusive texture for overnight use. However, the retinol concentration is not disclosed, so there is no way from public data to assess whether the retinoid is present at a level that can deliver the anti-ageing results the product claims. Fragrance in a retinol product introduces an inflammatory risk that builds over the full overnight contact period, working against the skin renewal retinol is intended to support. The two azo dyes add no formula logic benefit. Parfum without a published allergen breakdown in a leave-on product is also a formula logic concern.

The full ingredient list is published on the product page. Retinol concentration is not disclosed, which is the most critical number in this product. Without it, consumers cannot judge whether the retinoid is present at a meaningful dose. Parfum is listed as a single entry without naming the individual fragrance compounds, preventing consumers from checking for specific allergens. The two azo dyes are present with no explanation. The product does not carry a pregnancy warning despite containing a retinoid. No clinical study data has been published. Multiple claims rely on undisclosed ingredient doses.

The brand publishes the ingredient list but discloses no retinol concentration, no fragrance allergen breakdown, and no explanation for the two cosmetic dyes. No lab test report, clinical anti-ageing study, preservative efficacy test, or safety assessment is publicly accessible. For a leave-on overnight retinol product with fragrance, a full safety assessment and preservative efficacy test result would be the minimum expected public evidence. The absence of a pregnancy safety warning for a retinoid-containing product is also a transparency gap.

Basic application instructions are present. However, a pregnancy warning is absent despite containing a retinoid. The retinol concentration is not disclosed, so consumers cannot make an informed comparison with other retinol products. The sensitisation risk from combining fragrance and two azo dyes in an overnight leave-on is not communicated. Layering guidance is absent.
