Packaged in an elegant couture case, the C04 Rainbow shade offers a subtle shimmer and is designed to suit a range of skin tones.

How does the color-changing technology work on my lips?

The Catkin C04 Rainbow uses pH-responsive ingredients that react with the natural acidity of your lips to create a bespoke tint. It applies clear and gradually reveals a pinkish glow and shimmer unique to each wearer, lasting several hours without needing constant reapplication.

• Applies transparent, then develops a custom pink shimmer.
• Lasts up to six hours for visible color change.
• Suitable for natural, buildable everyday looks.

Will this keep my lips moisturized and soft all day?

The formula blends emollients and occlusives to lock in moisture and soothe cracked or dry lips. With ingredients like jojoba and meadowfoam seed oils plus vitamin E, it supports lip hydration and can improve lip texture with regular use.

• Provides immediate softening and smooth texture.
• Claims up to 24 hours of hydration effects per application window.
• Continued use helps reduce flakiness and lighten fine lip lines.

Can I use Catkin C04 before or under lipstick?

Yes — the balm is designed to act as a prepping step that enhances lipstick application and overall lip appearance. Use it under color lipstick to create a smoother base, or wear it alone for a subtle, natural glow.

• Prepares lips for more even lipstick coverage.
• Adds a light shimmer when worn solo.
• Small couture tube fits easily into makeup bags for touch-ups.

How quickly will I notice long-term improvements?

Users may observe softer, clearer lip skin after about two weeks of consistent daily use. The product’s nourishing components help reduce dead skin and improve lip lines over time, though results vary by individual.

• Visible softening and reduced flakiness in roughly two weeks.
• Improved lip texture enhances makeup finish over time.
• Regular use supports lasting moisture retention.

Who is this for? Catkin C04 Rainbow is suited for anyone seeking a low-effort, natural-looking lip product that doubles as both care and tint — ideal for people with dry or chapped lips, those who want a customizable everyday tint, and anyone who prefers compact, travel-friendly packaging. It’s a good fit for users who appreciate plant-derived oils and vitamin E in their lip care routine, and for buyers looking to simplify their makeup while keeping lips nourished and subtly colored.
