The Ordinary PHA 5% Exfoliating Lip Serum

The Ordinary PHA 5% Exfoliating Lip Serum offers a lip scrub alternative that uses gluconolactone and gentle AHAs to exfoliate and smooth lips, with an overnight focus. It aims to respect the lip barrier while promoting renewed appearance for a more radiant finish. The formula also includes black carrot extract to provide mild color and antioxidants, while boosting moisture content by about 30% in clinical testing conducted on a small panel. This product suits users seeking a light exfoliation paired with hydration rather than a heavy balm presence.
LANEIGE Glaze Craze Lip Serum

LANEIGE Glaze Craze Lip Serum delivers color-drenched, serum-infused hydration in four donut-inspired shades. It emphasizes a glassy finish and nourishment, with a claim that 95% of the formula is skincare in every swipe. The product is designed to be worn alone or layered with lip liner and other lip products for a buildable shine, making it ideal for those seeking a glossy, plumped look with ongoing moisture throughout the day.
The Ordinary Squalane + Amino Acids Hydrating Lip Balm

This lip balm combines squalane for immediate, lasting hydration with amino acids to help seal in moisture. It is designed to soften and nourish dry or rough lip areas, delivering a rich balm texture that supports the skin’s barrier. The formulation aims to keep lips softer and smoother, making it a reliable everyday hydrator for those with dry or sensitive lips who want a low-effort, daily moisturizer.
Wonderskin Lip Rehab Oil

Wonderskin Lip Rehab Oil is a clear, glossy formula crafted with a blend of nourishing oils and shea butter, designed to deeply moisturize and protect dry lips. It emphasizes a dual-action approach—hydrating to restore moisture and providing a subtle lightening effect over time for a naturally brighter look. The oil is formulated to feel non-sticky while delivering long-lasting comfort, suitable for daily use or as a nighttime treatment.
The Ordinary Hyaluronic Acid 2% + B5

This multi-depth hydration serum targets the lips by delivering immediate moisture, supporting the skin barrier with ceramides, and reducing the appearance of fine lines. While marketed as a facial serum, its hydrating properties and lightweight texture make it suitable for lip care when used in small amounts or layered with a balm. It can help impart a smoother feel and improved elasticity, particularly in drier climates or seasons.
LANEIGE Glaze Craze Donut Delight Lip Serum Duo

LANEIGE’s Donut Delight Duo combines two Glaze Craze lip serums in pink-toned shades with a donut-themed keychain. This set emphasizes glossy, hydrating lip serums with practical color payoff and a playful accessory. The formulas are designed to deliver moisture, shine, and a degree of plumping effect, making it a good option for users who want both performance and a collectible bonus item.
Leovard Lip Luster Hyaluronic Lip Balm

Leovard Lip Luster combines hyaluronic acid with nourishing components to deliver instant softness and long-lasting moisture. It targets dry lips and fine lines, functioning as both a hydrating lip serum and a light daily lip balm. The formula emphasizes daily use and compatibility with a non-toxic skincare routine, aiming to reduce dryness while supporting the lips’ natural fullness.
NYX Lip IV Hydrating Glossy Lip Stain

NYX Lip IV provides a hydrating gloss-stain experience with up to 12 hours of hydration. It delivers a glossy, lipstick-like tint with a refreshing feel. Infused with magnesium, vitamin B12, and coconut water, this product is positioned for those seeking a long-wearing color that also promotes moisture and lip comfort throughout the day.
Buying Guide: Key Considerations And Comparisons
- Hydration mechanism: Look for humectants like hyaluronic acid and glycerin, emollients such as squalane and oils, and barrier-supporting ingredients like ceramides. This combination tends to deliver immediate moisture and longer-lasting comfort.
- Overnight vs. daytime use: Overnight exfoliating formulas (e.g., PHA-based lip serums) can renew texture, while clear oils or balms focus on daylong hydration and protection. Consider mixing an exfoliant with a hydrating balm for a balanced routine.
- Color and finish: If you want a tinted or glossy finish, options from LANÉIGE offer color with shine, while clear oils provide hydration without tint. Consider whether you prefer a subtle tint or a high-gloss shine.
- Skin barrier compatibility: People with sensitive or compromised lips should prioritize gentle exfoliants and barrier-supporting formulas (ceramides, fatty acids) to prevent irritation and redness.
- Texture and feel: Some user experiences favor lightweight serums that layer easily under lipstick, while richer balms provide immediate comfort but may feel heavier. Personal preference matters for daily wear.
- Ingredient transparency: Brands like The Ordinary highlight active ingredients and concentrations, which helps in creating a targeted routine. Consider how much ingredient detail you prefer when selecting a product.
- Longevity and layering: Hydrating serums can be layered under lip balms or toppers. If you wear long-wear lip products, you may want a hydrating base to prevent dryness and cracking.
- Allergen and ethics notes: Some products are vegan or focus on natural oils. If you have sensitivities, check for fragrance-free formulas or specific plant-based ingredients.
Choosing the right lip hydrating serum involves aligning your goals—hydration, texture improvement, color, or plumping—with your daily routine. The options above range from gentle exfoliation to pure moisture, offering different paths to softer, more comfortable lips.
