News Letter

Hello,
Greetings from Sunjin Beauty Science.
Lip balm is one of the most frequently reapplied personal care products used throughout the day. In particular, lip balms with UV protection not only help protect the lips from sun exposure but may also be unintentionally ingested in small amounts. As a result, the safety of their ingredients is considered even more critical than that of many other cosmetic products.
Reflecting this concern, the global market is placing increasing emphasis on heavy metal safety in lip care products. Regulations on heavy metals in cosmetics are becoming more stringent, beginning with Washington State in the United States, while leading global brands are proactively adopting low heavy metal ingredients to stay ahead of evolving market expectations.

At the same time, Gen Z consumers are paying closer attention to ingredient safety, environmental impact, and the overall sensory experience of cosmetic products. Lip balm has evolved beyond a simple moisturizing product—it is now expected to deliver skin-friendly ingredients, effective performance, and a pleasant user experience all at once.
In response to these market trends, Sunjin Beauty Science is proud to introduce the GenZ Mineral Lip Balm SPF15 PA+ formulation, featuring our Ultra-Pure Mineral UV Filter technology and differentiated sensory performance for an elevated application experience.

Point 1. PureZn-AS: “Safe UV Protection, Comfortable Lip Care”

Today's consumers look beyond UV protection, paying close attention to ingredient safety, skin compatibility, and impurity control. For SPF lip balms, which may be unintentionally ingested during daily use, even higher safety standards are expected.
PureZn-AS is Sunjin Beauty Science's ultra-pure Zinc Oxide, engineered with premium purification technology to reduce lead (Pb) content to approximately 0.03 ppm. With enhanced heavy metal control, it is an ideal mineral UV filter for formulating safer, high-performance lip care products.
Beyond broad-spectrum UV protection, PureZn-AS offers excellent skin compatibility and helps protect delicate lips, delivering a comfortable feel even on sensitive skin. Its gentle sensory profile makes it suitable for a wide range of lip care formulations.

Point 2. EZLite-SF: “Redefining the Feel of Plant-Based Oils”

While effective moisturization is essential for lip balms, excessive oiliness can compromise the user experience. Today's consumers increasingly prefer lightweight, comfortable lip balms over greasy or heavy formulations. EZLite-SF is a next-generation lightweight emollient oil developed using enzyme treatment technology to improve the heavy feel typically associated with sunflower oil. It retains the moisturizing benefits of plant-based oils while delivering a light, fresh finish, enhancing the overall sensory experience of lip balm formulations. In stick formulations, EZLite-SF provides smooth glide and even application, ensuring a comfortable, non-dragging feel with every use.

Point 3. SUNSIL-50UH: “Firm Stick, Smooth Application”

In lip balm formulation, stick hardness and application feel often involve a trade-off. A firmer stick can compromise glide, while a softer texture may reduce product stability.
SUNSIL-50UH is a high oil-absorbing silica with an average particle size of 4 μm, designed to overcome these formulation challenges. Its superior oil absorption efficiently controls the oil phase, enhancing stick hardness and structural stability while delivering a smooth payoff.
As a result, formulations maintain their shape during storage and use, while providing a smooth, comfortable glide upon application for an ideal user experience.

Why Sunjin Beauty Science?

Today's consumers evaluate more than UV protection—they also consider ingredient safety, sensory performance, and a brand's commitment to responsible ingredient selection.
As lip products are applied directly to the lips, expectations for heavy metal control are only expected to grow.
The GenZ Pure Dewy Mineral Lip Balm from Sunjin Beauty Science brings these essential elements together. Formulated with PureZn-AS for enhanced safety, EZLite-SF for a lightweight, comfortable feel, and SUNSIL-50UH for excellent structural stability and smooth payoff, it delivers a balanced lip care solution without compromising performance or user experience.

Because lip products may be unintentionally ingested during use, they require particularly high safety standards. With its enhanced heavy metal control, PureZn-AS is an ideal mineral UV filter for lip care formulations.

Q2. How is EZLite-SF different from conventional plant-based oils?
EZLite-SF is a lightweight emollient oil developed using enzyme treatment technology to improve the heavy feel typically associated with sunflower oil. It retains the moisturizing benefits of plant-based oils while reducing greasiness and delivering a lighter, fresher skin feel.

Q3. What benefits does EZLite-SF provide in lip balm formulations?
EZLite-SF delivers smooth glide and even application in lip balm formulations. It also reduces excessive oiliness, creating the lightweight and comfortable sensory experience preferred by today's consumers.

Q4. What role does SUNSIL-50UH play in lip balm formulations?
SUNSIL-50UH is a high oil-absorbing silica with an average particle size of 4 μm. It efficiently controls the oil phase, helping improve stick hardness and structural stability.

Q5. Does SUNSIL-50UH improve hardness at the expense of application?
No. Thanks to its high oil absorption, SUNSIL-50UH enhances stick stability while maintaining excellent payoff. This enables formulators to achieve an optimal balance between stick hardness and smooth application.
