Updated:

Lip wrinkles present unique formulation challenges due to the distinctive properties of labial tissue, which is 3-5 times thinner than facial skin and contains fewer oil glands. Clinical measurements show accelerated moisture loss in this region, with transepidermal water loss (TEWL) rates up to 30% higher than surrounding facial areas, while mechanical stress from daily activities creates repetitive strain patterns.

The fundamental challenge lies in developing formulations that can maintain stable active ingredient delivery while addressing both surface texture and deeper structural changes in this highly mobile, moisture-sensitive tissue.

This page brings together solutions from recent research—including ceramide-based barrier repair systems, hyaluronic acid hydrogel nanoparticles for sustained hydration, oligopeptide complexes for elasticity enhancement, and silicone polymer matrices for wrinkle filling. These and other approaches focus on creating practical formulations that maintain efficacy while accommodating the unique characteristics of lip tissue.

1. Cosmetic Composition with Rosehip Oil and Centella Asiatica in Specific Ratio for Skin Moisturization and Elasticity

Lee Hong-koo, Ttlekkot Co., Ltd., LEE HONG KU, 2024

Cosmetic composition for improving neck wrinkles and lip wrinkles that provides both skin moisturization and skin elasticity. The composition combines purified water, natural vegetable oil, a moisturizer, a skin conditioning agent, and a skin elasticity improving agent, with a specific ratio of 100:1:5:5:0.1. The composition contains rosehip oil, a skin regeneration agent, and Centella asiatica, a skin elasticity enhancer, in addition to the purified water, natural vegetable oil, and moisturizer. The composition is formulated to deliver both hydration and skin elasticity benefits while minimizing skin irritation, making it suitable for improving skin texture and appearance on the neck and lips.

2. Silicone Emulsion with Hyaluronic Acid-Stimulating Actives for Enhanced Lip Wrinkle Filling and Hydration

NATURA COSMÉTICOS SA, 2023

A silicone emulsion for anti-aging cosmetic treatments that effectively fills deep wrinkles on the lips by stimulating hyaluronic acid production and providing enhanced hydration. The composition combines hyaluronic acid-stimulating active ingredients with a silicone emulsion that encourages natural skin cell activity and fills wrinkles through increased water uptake. This dual-action approach provides optimal performance in treating deep lip wrinkles while also delivering enhanced hydration and skin elasticity.

3. Cosmetic Composition with Ceramide, Jojoba Esters, Fatty Acids, Triglycerides, and Beta-Hydroxy Acid for Lip Skin Protection

COREANA COSMETICS CO LTD, 2021

Cosmetic composition for protecting lip skin that combines moisturizing, exfoliating, and wrinkle-improving effects. The composition contains ceramide, jojoba esters, fatty acids, triglycerides, and beta-hydroxy acid as active ingredients, along with an exfoliating agent like beta-hydroxy acid and an anti-wrinkle agent like adenosine. The composition maintains its shape during storage and maintains its moisture barrier properties, while delivering enhanced lip protection and wrinkle reduction through these key active ingredients.

4. Lip Care Composition with Centella Asiatica, Palmitoyl Oligopeptides, Ceramides, and Natural Waxes

GUANGZHOU NABIANG BIO TECH CO LTD, 2020

A lip care product that effectively reduces lip lines through a synergistic blend of natural ingredients. The formulation combines Centella asiatica extract, palmitoyl oligopeptides, ceramides, natural waxes, polyols, and liquid oils to create a stable and gentle lip care product. The active ingredients work together to improve skin elasticity, reduce water loss, and protect against environmental stressors. The product is formulated without preservatives, antioxidants, or UV radiation, making it a safe and effective solution for lip care.

5. Lip Cosmetic Composition with Natural Ceramide and Rosehip Oil

GENPEAU CORP, 2018

Lip cosmetic composition containing natural ceramide and rosehip oil as active ingredients, providing enhanced lip moisturization and wrinkle repair. The composition combines ceramide, a skin barrier component, with rosehip oil, a potent antioxidant and skin rejuvenator, to deliver superior lip protection and skin health benefits. The ceramide enhances skin barrier function, while rosehip oil addresses skin aging and inflammation. The combination provides comprehensive lip care through both moisturization and wrinkle repair, making it particularly effective for lip protection and skin rejuvenation.

6. Cosmetic Composition with Hyaluronic Acid Hydrogel Nanoparticles and Cross-Linked Olereahnolsan

Amorepacific, AMOREPACIFIC CORP, 2014

A lip-plumping and wrinkle-reducing cosmetic composition that simultaneously addresses lip volume and skin elasticity concerns. The composition comprises hyaluronic acid hydrogel nanoparticles and olereahnolsan, which are chemically cross-linked to form a stable swelling agent. The hyaluronic acid hydrogel nanoparticles are dispersed in a blend of ester-based oil and thickener, while the olereahnolsan is added in a controlled concentration. This composition provides sustained lip volume without irritation, while simultaneously addressing lip wrinkles through the anti-wrinkle effect of olereahnolsan.

7. Lipstick Composition with Oligo Peptides and Variable Amplitude for Moisture Retention and Lip Enhancement

SONGCHUL GYU, 2008

Lipstick composition containing oligo peptides that provides a moisturizing effect while enhancing lip appearance and circulation. The formulation combines a blend of natural and synthetic ingredients, including lip peptides, vitamin E, and plant extracts, to deliver a balanced moisture and lip care experience. The peptides promote blood circulation, reduce lip wrinkles, and enhance lip volume, while maintaining a natural gloss finish. The formulation is designed to provide a smooth, non-glossy appearance with excellent moisturizing properties, making it suitable for everyday wear.

8. Topical Composition with Sustained Release Formulation of Lip Volume-Enhancing Compounds

MCCARTHY KATHRYN J, 2005

Topical compositions and methods for enhancing lip appearance through sustained release of lip volume-enhancing compounds. The compositions contain sustained release formulations of lip volume-enhancing ingredients, such as vitamin C, proline, and lysine, combined with delivery systems that maintain consistent concentrations of these ingredients over extended periods. This sustained release enables consistent and prolonged effects of lip volume enhancement, overcoming the limitations of traditional topical treatments that often require repeated applications or have short durations of action. The formulations are designed to provide sustained release of lip volume-enhancing compounds to the lip tissues, compensating for the thin skin of the lips and their limited capacity for storage.

9. Cosmetic Composition with Silicone Polymers and Skin-Smoothing Agents for Lip and Perioral Application

DORF PAULA, 2002

A cosmetic composition for application to the lips and surrounding skin area to fill in superficial cracks, crevices, and wrinkles, enhancing lip appearance and preventing lipstick smudging. The composition contains a blend of silicone-based polymers, antioxidants, and skin-smoothing agents to create a smooth, seamless finish. It is particularly effective for the lip area, where fine lines and wrinkles commonly form, and provides long-lasting, colorless coverage that prevents lipstick from seeping into surrounding skin crevices.
