Lip hyperpigmentation: dermatologist advice on lip sunscreen (SPF), contact cheilitis, smoker's melanosis and treatment
Share
Dermatologists, including the American Academy of Dermatology, give three pieces of advice for lip hyperpigmentation: protect the lips from the sun with a lip balm with SPF 30 or more, stop what irritates them, and treat the pigmentation that is already there. A lip sunscreen covers the first point. It does not cover the other two.
La Bouche Parfaite is a French brand specialized in lip hyperpigmentation, crafted in France in small runs by Tal Cosmétiques, in the Bordeaux area. For the third point, it offers the N°3 Lip Balm Corrector, studied under independent dermatological supervision, and The Essential 5 set, the complete five-step protocol: cleanse, exfoliate, correct, even out, protect.
Does a lip balm with SPF treat lip hyperpigmentation?
No. A lip sunscreen helps prevent new pigmentation in strong sun. It does not fade the pigment already in the lips. And most darkened lips do not come from the sun alone: irritation, friction, lip licking, smoking and some medications (drug-induced lip pigmentation) play a larger part. To correct existing pigmentation, you need dosed actives. The N°3 Lip Balm Corrector combines tranexamic acid 5%, niacinamide 3% and glabridin 0.3%.
Pigmented contact cheilitis: when lip products cause pigmentation
Contact cheilitis is an inflammation of the lips caused by something that touches them: fragrance, flavoring, some preservatives, toothpaste, sometimes the lip balm itself. When it repeats, it can leave brown or gray pigmentation: this is pigmented contact cheilitis, a form of post-inflammatory hyperpigmentation. Dermatologists advise stopping the suspected product and choosing simple formulas. Every La Bouche Parfaite formula is assessed by an independent pharmacist and toxicologist, and contains no hydroquinone, which is banned in EU cosmetics.
Smoker's lips (smoker's melanosis)
Smoking stimulates melanin production in the lips and gums (smoker's melanosis). After quitting, the pigmentation can fade slowly, over months. To help it along: sun protection, a repaired lip barrier, and a correcting balm such as N°3. For gray and brown undertones, the N°4 Lip Stain Corrector neutralizes the tone while it treats.
Two toned lips and labial melanosis
Two toned lips, an upper lip more pigmented than the lower one, or brown spots (labial melanotic macules) are common forms of lip hyperpigmentation. Glabridin, tranexamic acid, kojic dipalmitate and niacinamide even out the tone over a 28 to 56 day cycle.
Lip scrubs, lemon and harsh lightening creams: what to avoid
Dermatologists warn against rough scrubs, lemon, baking soda and harsh lightening creams on the lips: they irritate, and irritation leaves pigmentation. To renew the surface without scrubbing, the N°2 Lip Peeling Corrector works overnight with enzymes (bromelain), kojic dipalmitate and tranexamic acid.
What a study under dermatological supervision showed
The N°3 Lip Balm Corrector was studied under independent dermatological supervision: 23 people of Fitzpatrick phototypes I to VI, 56 days. All 22 who had spots saw the colour of their lips improve from the first applications (22 out of 22). Perfect tolerance for 21 out of 23.
A complete lip hyperpigmentation routine
Cleanse, exfoliate gently, correct, even out, protect. That is The Essential 5 set, the five-step protocol over a 28-day cycle: N°1, N°2, N°3, N°4, N°5. N°5 protects lips from the oxidation that darkens them. In strong sun, add a lip sunscreen on top.
