FAQ

Dark lips are caused by an overproduction of melanin in the lip tissue. Unlike facial skin (which has around 16 cell layers), the lip mucosa is only 3 to 5 cell layers thick and has none of the natural defenses that regular skin has (no oil glands, no pores, no ability to sweat). This makes it far more vulnerable to damage.

The most common triggers include sun exposure (UV), smoking, hormonal changes, certain medications, and irritating cosmetic products. Be cautious with abrasive methods often recommended online (sugar scrubs, toothbrush exfoliation): they create micro-tears that trigger reactive hyperpigmentation and make the problem worse, not better.

No, and this is one of the most widespread mistakes. Sugar crystals create micro-tears in the lip mucosa, and toothbrush bristles are far too harsh for tissue this thin (3 to 5 cell layers). The result is inflammation that triggers a defense response: melanocytes (pigment-producing cells) generate more melanin to protect the injured area. This is called post-inflammatory hyperpigmentation.

Lips may feel smoother for a few hours, but they gradually darken over the following days. When the method is stopped, the pigmentation rebound can be more pronounced than the original state. To exfoliate lips safely, you need enzymatic exfoliation that dissolves dead cells without mechanical aggression.

Most commercial lip balms contain mineral oils (petroleum derivatives) or waxes that form a sealing film on the lip surface. This film temporarily prevents water from evaporating, creating a sensation of hydration. But it does not penetrate the cell layers and has no effect on melanin.

To correct established pigmentation, you need active ingredients that can reach the pigment-producing cells and inhibit tyrosinase, the enzyme responsible for melanin production. A standard lip balm cannot work at this depth or alter pigment production.

Yes. Lip hyperpigmentation occurs across all six Fitzpatrick skin phototypes, from the lightest to the darkest complexions. Its appearance varies: on lighter skin, it often shows as localized spots, brownish patches, or purplish undertones. On darker skin, it tends to appear as an overall darkening or uneven tone across the lip surface.

Melanin concentration in the lips is a natural biological variable that is not limited to any specific skin tone. Discover how your skin tone influences your lip pigmentation.

In the vast majority of cases, dark spots on the lips are benign. The most common causes are sun exposure, post-inflammatory hyperpigmentation, smoking, or conditions like labial melanotic macule (a localized melanin spot, similar to a freckle).

However, any lesion that changes in size, shape, or color over time should be evaluated by a dermatologist to rule out other conditions.

Smoking-related lip pigmentation, called smoker's melanosis, is caused by nicotine and other chemicals found in smoke that directly stimulate melanocytes in the lip tissue. This type of pigmentation is among the most responsive to corrective care once the source of irritation is reduced or stopped.

A consistent corrective protocol focused on cell renewal and melanin regulation can progressively restore a more even lip tone. You should generally expect at least one 28-day cycle, corresponding to a complete cell renewal of the mucosa, before seeing the first visible results.

Yes. When a lip blush or lip tattoo procedure triggers a tissue reaction, the result can be post-inflammatory hyperpigmentation. This risk is directly linked to the thinness of the lip mucosa (only 3 to 5 cell layers), which makes it highly reactive to needle trauma. The risk is statistically higher on darker skin tones (phototypes IV to VI), where melanocytes are more numerous and more reactive.

The affected area may appear darker or uneven once the tattoo pigment fades. A targeted corrective protocol can support cell renewal to gradually even out the lip tone. Read our full guide on lip blush gone wrong.

Lip preparation for makeup starts with the condition of the mucosa itself. Dehydrated lips, peeling skin, or a compromised protective barrier will produce an uneven result regardless of which lipstick you use. Makeup adheres poorly to a rough surface and bleeds into fine lines.

An effective prep routine includes gentle exfoliation (enzymatic, never abrasive), followed by a hydrating treatment that penetrates the cell layers rather than simply sitting on the surface. It is the health of the lip tissue that determines how well makeup holds and how it looks. Read our guide on lip prep before lipstick.

Yes. The lip mucosa produces almost no protective melanin and lacks the thick protective outer layer that the rest of your face has. This makes lips more vulnerable to UV damage than the surrounding skin. Repeated sun exposure is one of the leading causes of dark spots and premature aging on the lips. Over time, it can also contribute to conditions like actinic cheilitis (a precancerous lip condition caused by sun exposure).

Lip SPF should be part of your daily routine, just like facial sunscreen, especially during summer and at high altitudes.

Coconut oil and shea butter are good emollients: they soften and protect the lip surface. But they have zero effect on melanin. No oil or butter, however natural, can inhibit tyrosinase (the enzyme that produces pigment) or speed up the renewal of pigmented cells.

These ingredients can be part of a maintenance routine, but they are not a corrective treatment. The distinction matters: maintaining healthy lips and correcting established hyperpigmentation are two different things that require different approaches.

Ingredients with documented efficacy on melanin regulation include ingredients that block the enzyme responsible for pigment production (such as alpha-arbutin and kojic acid), certain biomimetic peptides that help cells communicate with each other, and hyaluronic acid for deep hydration of the cell layers. The effectiveness of these ingredients depends on their concentration and their ability to penetrate the layers of the lip mucosa, which requires formulations specifically designed for this area.

An ingredient that works on facial skin is not necessarily effective on lips: the lip mucosa has a different structure, thickness, and permeability.

LIPS-ID is a diagnostic tool that uses your phone or computer camera to analyze your lip pigmentation in real time. The system identifies your skin tone and measures the intensity of your pigmentation on a scale of 0 to 10. Based on this score, it generates a personalized corrective recommendation.

The analysis takes about 2 minutes and requires no download. Your images are not stored: the analysis runs locally on your device.

The complete protocol consists of five products, each designed for a specific step: No. 1 Lip Cleanser Corrector (preparation), No. 2 Lip Peeling Corrector (cell renewal through enzymatic exfoliation), No. 3 Lip Balm Corrector (hydration and pigment regulation), No. 4 Lip Stain Corrector (tone correction), No. 5 Lip Gloss Corrector (protection and luminosity).

All five products work together to treat the different layers of the lip tissue over a complete cycle. Discover The Essential 5 kit.

Improved hydration and texture are generally noticeable from the first applications. For visible pigmentation correction and a more even tone, you should expect one 28-day cycle of regular use, corresponding to a complete cell renewal of the lip mucosa.

The speed of improvement depends on the intensity of your initial pigmentation and your skin tone. This is why LIPS-ID personalizes your journey based on your starting point.

Yes. The protocol is designed to work across all six Fitzpatrick skin phototypes. LIPS-ID identifies your skin tone during the diagnosis and adjusts the recommendation accordingly. Whether your natural lip pigmentation is light, medium, or dark, the protocol targets the melanin regulation process rather than applying a one-size-fits-all approach.

Each product can be used on its own. Corrective results are optimized when all five steps are used together in order: the Cleanser prepares the surface, the Peeling renews cells, the Balm regulates and hydrates, the Stain maintains tone correction, and the Gloss protects the whole process.

If you are not sure which products are right for you, LIPS-ID will recommend the right combination based on your score.

The formulas contain a combination of active ingredients targeted for their efficacy on lip tissue: biomimetic peptides that help cells communicate with each other, plant-based brightening agents to regulate pigment production, hyaluronic acid for hydration, and Volulip™ for lip volume. Each product in the protocol uses a distinct active complex, formulated for its specific corrective step.

Yes. The lip mucosa is one of the most delicate areas of the face, and the formulations are developed with this in mind. The products are tested for tolerance on the lip area and do not contain aggressive irritants. If you have a known allergy to a specific ingredient, please check the full ingredient list on each product page before use.

The formulas use cosmetic-grade ingredients generally considered safe for external use. However, as with any skincare product during pregnancy or breastfeeding, we recommend consulting your healthcare professional before starting a new routine. This is a standard precaution.
