Cathy Doll Unveils Intensive UV Lip Serum: Your Secret Weapon Against Sun and Dryness
A New Era of Lip Care Arrives with 13 Plant Oils and Powerful UV Protection
The world of beauty is buzzing with the upcoming launch of Cathy Doll’s “Intensive UV Lip Serum,” a revolutionary product designed to shield your lips from both harsh UV rays and dehydrating dryness. Developed by Thai cosmetics brand Cathy Doll, known for its playful “doll” concept, this serum is set to redefine daily lip care. It will first grace digital shelves on Rakuten (Citrus Market official shop) starting January 9, 2026, at 12:00 PM JST, followed by a gradual rollout in Don Quijote stores across Japan from early January 2026.
Lips, often overlooked in daily skincare routines, are in fact one of the most vulnerable areas of the face to sun damage. Their thin, delicate skin makes them prone to issues like dryness, peeling, dullness (due to dryness and uneven texture), and vertical lines. This makes comprehensive UV care for lips as crucial as it is for the rest of your skin.
Triple Threat: UV Protection, Deep Hydration, and Natural Radiance
The “CathyDoll Intensive UV Lip Serum” addresses these concerns head-on. It’s a vegan, multi-functional lip product that combines UV protection, intense hydration, and a natural enhancement of lip color. This innovative formula is also committed to ethical beauty, being cruelty-free and reef-safe, alongside a “7-free” promise, excluding UV absorbers, parabens, mineral oil, alcohol (ethanol), and synthetic dyes.
1. Blocking Harmful UV Rays
This lip serum acts as a shield, preventing UV damage while enhancing the natural beauty of your lips. It effectively blocks both UVB rays, which cause spots and freckles, and UVA rays, which penetrate deep into the skin. By delivering essential moisture, it helps keep lips healthy and prevents the hardening often caused by sun exposure and dryness.
2. Strengthening the Lip Barrier with Ceramides and Plant Oils
Lips have a weaker barrier function compared to other skin areas, making it vital to replenish ceramides, their primary barrier component. Additionally, lips have very few sebaceous glands to produce oil, so an external oil layer is crucial to lock in moisture.
The “CathyDoll Intensive UV Lip Serum” creates a hydrating film with a blend of three ceramides⁴ and thirteen plant oils² to protect lips from dryness and maintain a healthy, smooth texture. The carefully balanced combination of high-adherence and lightweight oils ensures a non-sticky, close-fitting finish.
Further enriching this formula are beauty moisturizing ingredients such as Vitamin C derivatives⁵, Bakuchiol, Sodium Hyaluronate, and Licorice Root Extract, all working to prevent moisture loss and keep lips fully hydrated.
3. Effortless Daily Wear with Natural Tints
Designed for everyday use, the serum offers a sheer, natural tint that blends seamlessly with your natural lip color, making it perfect even for makeup-free days. It adds a healthy flush and a subtle gloss, revitalizing dull-looking lips.
The serum is available in five appealing shades:
-
HEALTHY PEACH
-
HEALTHY PINK
-
HEALTHY ORANGE
-
HEALTHY RED
-
HEALTHY CARAMEL
