Repeat/holy-grail purchase
An unusually high share of reviewers explicitly state this is a repurchase (2nd, 3rd, even 5th+ bottle), calling it their 'holy grail' toner they always return to.
Refill + cotton pad bundle value
Many buyers chose this specific set because it includes a full-size eco refill pouch and cotton pads, seen as much more economical than buying the toner alone.
Gentle formula for sensitive/reactive skin
Consumers with sensitive, allergy-prone, rosacea, or eczema-prone skin purchased it specifically because it's reputed to be low-irritation and fragrance-free.
Word-of-mouth and brand loyalty
Several buyers bought it after trying other Round Lab products (cleanser, sunscreen) or on recommendation from friends, family, or even an AI chatbot.
Gifting
Multiple reviewers bought the set as a gift for a sister, daughter, or partner, citing its gentle, universally-suited formula.
