GlowLab, a Seoul-based DIY skincare brand popular for customizable serums and moisturizers, faced a critical challenge in 2024: inconsistent batch quality. Catering to eco-conscious consumers who mix their own skincare (choosing bases like hyaluronic acid or squalane with add-ons like vitamin C or niacinamide), the brand relied on manual mixing tools for its pre-blended base batches. This approach led to frustrating inconsistencies—some base batches were too thin, others had clumpy additive residues, and 16% of batches were rejected for failing to meet the brand’s “smooth, blendable” standard. Worse, customer complaints about uneven texture rose by 25% in Q1 2024, threatening its loyal customer base.
Seeking a solution that fit its small workshop (12㎡) and focus on “DIY-friendly” production, GlowLab invested in a 50L mini emulsifier with a 6,000rpm titanium shear head and adjustable speed settings. Unlike bulky industrial machines, this compact device could be stored under workbenches and operated by a single staff member. Its gentle yet powerful shear force broke down additive particles to ≤7μm, ensuring even dispersion in the base, while the adjustable speed prevented over-mixing (a common issue with manual tools that damaged delicate ingredients like hyaluronic acid).
The impact was immediate. Within six weeks, batch rejection rates plummeted to 2%, saving the brand 3.2 million KRW monthly in wasted materials. Customer complaints about texture dropped by 80%, and repeat purchase rates rose from 45% to 68%—many customers noted the “consistently smooth” bases made their DIY mixing easier. Production efficiency also improved: the mini emulsifier cut base-mixing time by 40%, allowing GlowLab to expand its base range from 3 to 5 variants (adding a sensitive-skin oat base and a firming peptide base).
“We didn’t need a big machine—this mini emulsifier understood our DIY brand’s needs,” said Park Ji-yeon, GlowLab’s founder. By mid-2024, the brand had partnered with three Korean wellness cafes to sell its customizable kits, with the emulsifier’s consistent output enabling it to meet the new demand without compromising quality. For GlowLab, the mini emulsifier wasn’t just equipment—it was a way to protect its brand promise of “accessible, high-quality DIY skincare.”
