rdrd Red Apple Lacto Calming Serum

What is this product?

rdrd's Red Apple Lacto Calming Serum earns its own name: lactobacillus ferment at roughly 4.9 percent and apple water at roughly 3.7 percent both sit in the top five of the ingredient list, with a separate small apple extract addition further down. The 'emergency soothing' marketing around its kit bundling is only partly earned by this specific formula: panthenol, trehalose and a cooling agent are genuinely present, but this variant skips the stronger centella-based actives that a parallel formula in the same kit carries.

What makes it different?

This 30ml serum is one of four parallel formulas (red, pink, green, gold) the brand sells as variants under one kit name, and this record covers only the red one that corresponds to the 30ml main item; a green variant in the same kit carries a heavier centella-and-salicylic-acid-derivative profile that this formula does not share. No fragrance ingredient and no exfoliating acid appear anywhere in its 27-item list.
