On May 28, a landmark event unfolded in Seoul: the Trendier AI Boot Camp, Korea’s first hands-on program applying GPT tools directly to the beauty industry.
Over 300 professionals from across the K-beauty sector, including teams from Amorepacific, LG Household & Health Care, COSMAX, Korea Kolmar, and fast-growing brands like COSRX, Anua, and TIRTIR. The strong turnout reflected the industry’s increasing interest in AI-powered work automation.
Many professionals adopting AI tools like ChatGPT report unclear or unhelpful results. At a recent boot camp hosted by Trendier AI, participants explored why — and found the problem often lies in how prompts are written and data is provided.
The event, Korea’s first hands-on program applying GPT-based tools to beauty business operations, focused on real-world applications over theory. Among the highlights, Trendier AI managers Jisun Shin and Songyeon Sim presented strategies for using GPT in product planning, marketing, and global sales. They also shared real-life prompt examples built on data from 25 key global beauty markets.
The program underscored how AI is beginning to reshape day-to-day functions across the K-beauty value chain.
To give you an idea of what the GPT hands-on camp was like, here’s a sample prompt they gave – “What markets are we missing right now?”
Participants used category reports and asked GPT questions like:
“Based on this 3-month report, which product categories are best to enter, considering growth, competition, and pricing flexibility?”
GPT gave detailed answers, such as:
- Essence-Serum: Fast-growing category
- Mist-Fixer: Small but has room to grow
- Lotion-Emulsion: Good fit for premium products
GPT also explained the reasons behind each suggestion and pointed out possible risks.
Detailed example: Understanding Competitor Thumbnails with GPT
Younsoo Choi, CEO of Future Planning Lab and a Trendier AI superuser, brought a real-world case to the table. With 20+ years in marketing roles at brands like Amorepacific, Banila Co., and Olive Young, she had one pressing question:
“How are our competitors’ thumbnails evolving? What direction are their brands heading?” Her team used GPT to dig in.
Step 1: Data Collection
Using Trendier AI’s dashboard, they extracted thumbnail images for foundation products at Olive Young over several months.
Step 2: Prompt Design
They told GPT:
“Analyze these thumbnails. What changed over time? Look at:
- Model use and timing
- Backgrounds, colors, and text
- Key message changes
- Brand strategy direction”
By combining data with ChatGPT analysis, you can improve your product planning and fine-tune your marketing message based on what real users say.
GPT didn’t just describe the visuals. It spotted patterns across time—when models were introduced, how tones and slogans evolved, and when brands subtly shifted positioning.
For the first time, strategy became measurable and trackable—not just intuition.
