Cellology Blue Eraser Serum

What is this product?

Cellology's Blue Eraser Serum is a centella and aloe leaning soothing serum, coloured with ultramarine pigment, sold through both the brand's own storefront and an Olive Young dermocosmetic listing. Its own product page claims NO.1 soothing status and a pharmacy and dermatology retail channel, and neither the ranking nor the channel claim has any supporting evidence in the collected material, though the calming ingredients themselves (madecassoside, asiaticoside, two aloe extracts, menthol) are genuinely present. Four essential oils and menthol mean reactive skin should patch test rather than take the immediate-soothing framing at face value. A functional cosmetic filing has been made for this product, though which statutory function it covers is not stated anywhere available. Concentrations, pH and container form are undisclosed.

What makes it different?

The blue colour is a real formulation choice, ultramarine printed in the statutory list, not a marketing filter, and it pairs with a soothing-leaning botanical stack built around centella and aloe rather than a single headline active. The undisclosed but structurally present mandelic acid is worth flagging for a reader who assumes a calming serum carries no exfoliation at all.
