Benefits
  • Visibly plumps on application Sodium hyaluronate draws water into the lip surface, so lips look fuller from the first use rather than only after weeks of consistency.
  • Supports lip structure over time Palmitoyl Tripeptide-1 supports collagen-related signalling in the lip. Structure and definition depend on that, which is what separates a treatment from a gloss.
  • Smooths the look of fine lip lines The vertical lines around the mouth are among the first to show, because the area moves constantly and has very little natural oil to protect it.
  • Delivers lasting hydration and softness A conditioning blend of jojoba, grape seed, olive, macadamia and castor oils, with squalane, slows the moisture loss that lips are especially prone to.
  • A cooling tip built for the ritual The Zamac metal applicator stays cool against the lip, making application feel refreshing and precise in a way a wand or a fingertip does not.
  • Supports defined lips between filler appointments Filler adds volume, but it does not condition the skin of the lip. This treats the lip surface itself, so the two are complementary rather than interchangeable.
Ingredients
  • Palmitoyl Tripeptide-1 A peptide that supports collagen-related signalling in the lip. Visible structure and definition depend on that support, which is what makes this a treatment rather than a gloss.
  • Sodium Hyaluronate A hyaluronic acid salt small enough to draw water into the lip surface, which is what gives lips a visibly plumper, softer look.
  • Squalane A lightweight emollient that slows moisture loss. Lips have no oil glands of their own, so they depend entirely on what you apply to them.
  • Pomegranate Flower Extract An antioxidant botanical that supports the lip barrier against the environmental stress lips absorb daily, from sun and wind to dry indoor air.
  • Menthone Cooling Complex Menthone Glycerin Acetal, which delivers the fresh cooling sensation you feel as you apply.

Frequently Asked Questions

Do I need lip filler to use the Lip Serum?

No. The Lip Serum is for anyone who wants lips to look smoother, more hydrated, more defined, and better cared for over time. It is especially helpful if you get lip filler, but it is designed to support lips with or without in-office treatments.

How does the Lip Serum support lips between filler appointments?

It helps keep lips looking hydrated, smooth, and more structured between appointments. While filler can restore or enhance volume, daily lip care helps maintain the look of healthier, more conditioned lips.

How soon after lip filler can I use the Lip Serum?

Follow your provider's aftercare instructions first. In many cases you can resume lip care once your provider has cleared topical products and the injection sites have healed. The formula is designed to be gentle, hydrating, and supportive for lips that need extra care after an in-office lip treatment.

Does the Lip Serum replace lip filler?

No. Lip filler and lip care do different things. Filler can add volume and shape, while the Lip Serum helps improve the look of hydration, smoothness, softness, and visible definition.

Can a lip serum make lips look fuller?

Yes. The Lip Serum helps lips look more hydrated, smoother, and more plump-looking over time, while supporting the look of lip structure and definition. In a four-week clinical study, 87% showed improvement in visible lip volume. Results build with consistent use. This is a skincare effect on the look of the lips, not a substitute for an in-office lip treatment.

Does the Lip Serum help with fine lines around the lips?

Yes. The formula helps smooth the look of fine lines on and around the lips by supporting hydration, softness, and the appearance of improved texture. In a four-week clinical study, 97% showed improvement in the look of lip fine lines.

Is the Lip Serum sticky?

No. It was designed to feel comfortable and wearable, with a cushiony treatment feel rather than a heavy or sticky finish.

How often should I use the Lip Serum?

Use daily, morning and night, or as needed throughout the day. Consistency is key for maintaining the look of softer, smoother, healthier lips.

Can I wear the Lip Serum with lipstick or lip liner?

Yes. Apply it as a treatment step before makeup, or use it on its own for a hydrated, polished finish.

What is the difference between a lip serum and a lip balm?

A balm mainly helps coat and comfort the lips. The DR. MARNIE Lip Serum is a targeted lip treatment designed to support hydration, smoothness, visible definition, and the look of lip structure over time, which makes it well suited to lips that feel dry, depleted, or in need of more than a traditional balm.

Is the Lip Serum fragrance-free?

No. The Lip Serum contains fragrance, along with listed fragrance allergens including limonene, linalool, benzyl benzoate, citronellol, and citral. The Facial Serum and Wrinkle Pen are fragrance-free; the Lip Serum is the exception.

Can skincare make Botox or filler last longer?

No. DR. MARNIE products help maintain the look of smoother, brighter, healthier skin between appointments. They do not change how your body metabolizes Botox or filler, but they can help support the look of your skin in between.

When can I use skincare again after Botox, filler, or laser?

Once your provider clears you to resume skincare. Their aftercare instructions always come first, and the timing varies by treatment. After that, DR. MARNIE products are designed to support the look of smoother, healthier skin between appointments, while filler addresses volume and contour and Botox addresses muscle movement. For laser and energy-based treatments, ask your provider specifically when to restart active skincare.
