Kiehl's Buttermask For Lips Overnight Lip Mask 0.35 fl oz — Intense Hydrating, Fragrance-Free

Kiehl's Buttermask For Lips is an intensely hydrating overnight lip mask formulated with Fairly Traded Coconut Oil and Wild Mango Butter to nourish and visibly restore dry lips by morning.

Designed as a concentrated leave-on treatment, this 0.35 fl oz pot delivers rich, butterscotch-textured hydration without parabens or added fragrance. The formula focuses on replenishing and helping to support the lip moisture barrier while providing a satin, non-sticky finish that can be used both overnight and as a short-term prep treatment before makeup application.

How should I use this lip mask for best overnight results?

Apply a generous, even layer to clean lips before bed and let the formula work while you sleep. It can be reapplied throughout the day for extra hydration, or used as a short treatment under makeup when you need smooth application.

• Night: apply a thick layer and leave on overnight for maximum restoration.
• Day: reapply on dry spots or as needed for instant comfort.
• Makeup prep: leave on for 15 minutes, blot excess, then apply lipstick or gloss.

What are the key ingredients and what do they do?

The formula centers on Fairly Traded Coconut Oil and Wild Mango Butter, chosen for their rich emollient and skin-conditioning properties. These botanicals help soften and smooth the delicate skin of the lips, while the overall formulation is kept free of parabens and fragrance for a gentler experience.

• Fairly Traded Coconut Oil: nourishes and helps retain surface moisture.
• Wild Mango Butter: adds smoothing, rich emollience for supple texture.
• Fragrance-free and paraben-free: reduces potential irritants for sensitive lips.

How quickly will I notice an improvement in my lips?

Many users report softer, more comfortable lips by morning after a single overnight application. With continued use, the lips typically look more supple and feel less dry as the formula helps maintain a healthier moisture balance.

• Immediate: softer feel after the first application.
• Overnight: visible smoothing and more comfortable lips by morning.
• With regular use: improved lip texture and reduced roughness.

Can I use this under lipstick or with other lip products?

Yes — the mask can be used as a short prep treatment before applying color. For best results, apply the mask for about 15 minutes, blot any excess, then layer your chosen lipstick or gloss for a smoother finish.

• Prep: 15-minute treatment, blot, then apply lip color.
• Layering: works well under lip balms and glosses when blotted.
• Non-sticky finish: helps color apply evenly without slippery residue.

Who is this for? Kiehl's Buttermask For Lips suits anyone with dry, rough, or chapped lips who wants a rich, leave-on treatment that’s simple to use. It’s appropriate for those seeking a fragrance-free, paraben-free option and people who prefer botanical-sourced emollients like coconut oil and mango butter. Ideal for nighttime repair, occasional intensive care, or as a prep step for smoother lip makeup application.
