Hey, I’m Liah! I create videos to make taking care of yourself more approachable by offering skincare, self-care, and lifestyle tips. This channel invites you to take care and #PressReset: I want to help you break down and decode the flood of information out there on all the rules, routines, and ingredients that surround us. I used to work in the beauty industry professionally, and now I’m pursuing my dream as an entrepreneur and content creator. My skincare brand KraveBeauty was born after talking to you for so many years and realizing that there was a real need for a more transparent approach to the skincare industry. I launched the KraveBeauty line based on simple but effective products, designed around what your skin intuitively craves, and committed to the utmost honesty with your well-being in mind first and foremost. I hope you find this space safe enough to open up candid conversation and share your personal journey with the rest of the #PalmPalmFam too. As always, take care.

This video is an interview-style roundup of skincare experts sharing their picks for the most overrated and underrated ingredients. It covers controversial ingredients like niacinamide, rosemary oil, vitamin C, zinc oxide, and also highlights overlooked ingredients such as azelaic acid derivatives, caprylic/capric triglyceride, silica, fragrance, sulfur, and emulsifiers. The overall takeaway is that marketing claims matter less than evidence, gentleness, and how a formula actually feels and performs.
- Overrated picks include niacinamide, rosemary oil, vitamin C, and zinc oxide
- Underrated picks include azelaic acid derivatives, caprylic/capric triglyceride, silica, fragrance, sulfur, and emulsifiers
- Several speakers criticize weak evidence, irritation, or exaggerated claims

Beauty Packaging HOT TAKES

Liah Yoo shares her hot takes on packaging trends she wants gone in 2026. She criticizes overpackaging, questions the real value of bio-based plastics, and is skeptical about refillable systems that may still create a lot of waste. Her overall message is that packaging should solve a problem, not add to one.
- Overpackaging makes products look more valuable, but it often just creates more plastic waste
- Bio-based plastics like sugarcane plastic are still questionable in curbside recycling and biodegradability
- Refillable packaging sounds good in theory, but inserts can still be heavily packaged
- A system that only reduces waste after many repurchases is not practical for most consumers
Beauty Supply Chain 101

This video explains how skincare products are made through three supply chain models. It walks through ingredient sourcing, formulation, and large-scale manufacturing, then compares outsourced, vertically integrated, and ODM setups. The main takeaway is that vertical integration offers control and traceability, while ODM offers speed but much less visibility.
- Skincare production starts with ingredients, then formulation and manufacturing.
- Outsourced supply chains give brands flexibility and low infrastructure.
- Vertical integration provides full control and traceability, but is capital intensive.
- ODM can launch products quickly, but ingredient traceability is limited.
