+ Lux Unfiltered N°15 Cold Plunge Soothing Lip Serum – Hydrating Lip Treatment with Ceramic Cooling Applicator, Hyaluronic + Squal

Lux Unfiltered N°15 Cold Plunge Soothing Lip Serum is a cooling, skincare-grade lip treatment that hydrates deeply, soothes chapped lips, and doubles as a gloss, primer, and overnight mask.

Designed like a facial serum for the lips, this petroleum-free, fragrance-free formula combines hyaluronic acid, squalane and liquid shea butter with botanical extracts for multi-layer hydration. The ceramic cooling applicator delivers a refreshing first touch while the lightweight serum penetrates past surface waxes to support more supple, smoother lips. Packaged for everyday use, it slips easily into a makeup bag, pocket, or bedside drawer.

How does the cold ceramic applicator change a lip balm experience?

The ceramic tip gives immediate cooling on contact, which calms sensitivity and creates a smooth, even glide. Unlike typical waxy sticks that sit on the surface, the applicator helps deposit a thin, concentrated layer of serum where it’s needed most. The sensation is refreshing and helps the product feel weightless while improving spreadability.

• Ceramic tip provides instant cooling and a soothing first touch
• Even product distribution with a single sweep
• Non-greasy finish that layers under makeup

What key ingredients are in N°15 and why do they matter?

N°15 blends hyaluronic acid to attract moisture, squalane for lipid support, and liquid shea butter to soften and condition. Botanical extracts like prickly pear and watermelon add antioxidant-rich, skin-friendly hydration. The formula avoids petroleum, fragrance, parabens and sulfates for a cleaner, gentler treatment.

• Hyaluronic acid draws and holds moisture within lip tissues
• Squalane restores a natural-feeling lipid layer without heaviness
• Liquid shea butter and extracts provide smoothing and soothing benefits

How can I use this product throughout my day and night routine?

N°15 is designed to adapt: use a light swipe over bare lips during the day, layer it over lipstick as a glossy topper, apply before color to smooth lines, or coat generously at night as an intensive repair mask. Because it’s lightweight and non-sticky, it functions well in all those roles without disrupting makeup or leaving residue on fabrics.

• Daily: one swipe for instant hydration and subtle shine
• Pre-makeup: acts as a smoothing primer for even application
• Overnight: thicker layer to lock in moisture and support repair
• On-the-go: quick cooling relief for chapped or irritated lips

Is this safe for sensitive lips and compatible with makeup?

The fragrance-free, petroleum-free, vegan formula minimizes irritants and helps lips recover without dependence on occlusive waxes. Lightweight oils and humectants make it compatible with most lip tints and lipsticks, including pairing well with Lux Unfiltered N°11 Lip Tints for hydrated color that lasts.

• Fragrance-free and free of parabens and sulfates
• Vegan, cruelty-free, and petroleum-free for cleaner care
• Works under or over lip color without pilling

Who is this for? N°15 is for anyone seeking more than a standard balm: shoppers who want a skincare-first lip treatment that calms sensitivity, delivers measurable moisture, and doubles as a beauty tool. It’s suited to people with chronically dry or chapped lips, makeup users who need a smoothing primer or glossy topper, and those who prefer clean, vegan formulas without fragrance. If you want a non-greasy, restorative lip serum that fits into morning makeup, midday touch-ups, and overnight routines, this product was formulated with you in mind.
