Melasma is the hyperpigmentation condition I see most often in my Irvine CA practice, and it is also the one where I have the most difficult conversations about expectations. Clients come in having tried everything, sometimes for years, and they want to know why nothing has cleared it permanently. The honest answer is that no current treatment permanently eliminates melasma. But significant, lasting improvement is absolutely achievable with the right approach.
Melasma is a chronic form of hyperpigmentation characterized by symmetrical patches of increased pigmentation on the face, most commonly across the cheeks, upper lip, nose bridge, chin, and forehead. It affects women far more than men, with women accounting for roughly 90 percent of cases. The patches vary in color from light brown to dark brown to grayish-brown depending on how deep in the skin the pigmentation sits.
What makes melasma uniquely stubborn compared to other hyperpigmentation types is the combination of two independent triggers that reinforce each other. Hormones sensitize melanocytes, the pigment-producing cells in the skin, to UV light. UV light then activates those sensitized melanocytes, triggering overproduction of melanin at a level that far exceeds the normal UV response. The result is persistent, deep pigmentation that returns whenever either trigger is present.
This dual-trigger mechanism explains why melasma treatment always requires addressing both the UV exposure and the hormonal component simultaneously. Treatments that target only one factor produce partial results at best. I have seen many clients in my Orange County practice who diligently applied topical treatments for months with minimal improvement because they were applying those treatments without adequate sun protection. The UV trigger was overriding every intervention they made.
Melasma pigmentation can sit in three different skin depths, which is another reason it is challenging. Epidermal melasma, in the upper skin layers, appears more brown and responds best to topical treatment. Dermal melasma, which has migrated into deeper skin layers, appears more gray or blue-brown and does not respond significantly to topicals. Mixed melasma has components at both depths. Determining which type a client has requires professional assessment, because the distinction changes the entire treatment strategy.
To understand melasma treatment, you need to understand exactly how estrogen and UV radiation interact at the cellular level. Estrogen receptors are present on melanocytes. When estrogen levels are elevated, whether from pregnancy, oral contraceptives, or hormone replacement therapy, those receptors increase melanocyte sensitivity to all stimulation, including UV light. A melanocyte that would normally produce a modest amount of melanin in response to sun exposure produces dramatically more when it is in a hormonally sensitized state.
UV radiation is the second necessary ingredient. Most people with melasma notice that their patches darken significantly in summer and may fade somewhat in winter. This seasonal pattern is direct evidence of the UV component at work. In Southern California, where I practice in Irvine, the UV index rarely drops below 3 even in winter, and regularly reaches 10 to 11 in summer months. This means year-round UV management is essential for my clients in ways that may be less critical in less sunny climates.
Research published in the past decade has established that visible light, not just UVA and UVB, also triggers melasma. Specifically, high-energy visible light (HVEV) in the blue-violet spectrum has been shown to stimulate melanin production in darker skin tones with the same intensity as UV radiation. This is an important and underappreciated factor because standard sunscreens do not block visible light. Only tinted sunscreens with iron oxide pigments provide meaningful visible light protection.
For my melasma clients in Orange County, I specifically recommend tinted mineral sunscreens with iron oxide rather than clear sunscreens, precisely because of this visible light component. The added protection layer makes a measurable difference in results, particularly for clients with Fitzpatrick skin types IV through VI who are most sensitive to visible light-triggered pigmentation.
Heat independently stimulates melanocytes through a mechanism separate from UV. Hot environments, hot showers, vigorous exercise that generates significant body heat, and thermal treatments including steam facials and hot stone massage can all trigger melasma flares. This is relevant both for avoiding flare triggers and for choosing appropriate professional treatments, because any treatment that introduces significant heat into melasma-affected skin can worsen rather than improve the condition.
I want to address something directly because it comes up often in consultations. Melasma is classified as a cosmetic condition, but the psychological burden it carries is substantial. Studies consistently show that melasma significantly affects quality of life, self-confidence, and social function. Clients who come to my Irvine studio with melasma are frequently dealing with significant distress about their appearance, and they often feel dismissed when the condition is described as "just cosmetic" by providers who underestimate its impact.
Understanding the full scope of the problem, including its psychological dimension, informs how I approach treatment planning. Goals need to be realistic, communication about timelines needs to be honest, and the management strategy needs to be sustainable enough to maintain over the long term. A treatment plan that requires heroic effort every day is unlikely to be followed consistently, and consistency is everything with melasma.
I also take time in consultations to discuss what "success" looks like with melasma, because it differs from other pigmentation conditions. Success with sun spots might mean near-complete clearing. Success with melasma more realistically means significant lightening, stable maintenance, and the ability to manage the condition without it dominating daily life. Framing treatment around management rather than cure produces more sustainable outcomes and more realistic satisfaction with results.
If I had to choose one intervention for a melasma client and nothing else, it would be strict daily broad-spectrum SPF 50 applied correctly every morning and reapplied every two hours during sun exposure. Not because other treatments are ineffective, but because no other treatment works in the presence of uncontrolled UV exposure. Sun protection is the foundation without which the entire structure of melasma treatment is unstable.
For melasma specifically, the sunscreen requirements are more demanding than for general skin protection:
The professional treatment approach to melasma is different from the approach to other hyperpigmentation types. The key distinction: aggressive treatments that work well on sun spots and PIH often make melasma worse. The inflammation, heat, and trauma produced by aggressive peels or laser can trigger post-inflammatory hyperpigmentation on top of existing melasma, deepening and complicating the picture.
A series of low-dose chemical peels with gentle acids is the most consistently effective professional treatment for melasma in my practice. I specifically use lactic acid and mandelic acid peels for melasma clients rather than glycolic acid, because their larger molecular sizes produce slower, more even exfoliation with significantly less irritation risk.
Lactic acid at 30 to 40 percent is my starting point for most melasma clients. It is the most hydrating of the alpha-hydroxy acids, which helps counteract the dryness that can accompany treatment. It exfoliates slowly enough that the inflammatory response is minimal, reducing the risk of PIH that can complicate melasma treatment in darker skin tones.
Mandelic acid is particularly well-suited for Fitzpatrick skin types IV through VI, where the risk of procedure-triggered PIH is highest. It has the largest molecular size of common AHAs, penetrates very slowly and evenly, and carries antibacterial properties that help maintain clear skin as a secondary benefit. A series of 6 mandelic acid peels spaced 3 to 4 weeks apart produces visible melasma improvement without the irritation risk of more aggressive approaches. Visit the chemical peels page for information on what to expect during a professional peel appointment.
Professional vitamin C infusions at 20 to 30 percent L-ascorbic acid concentration, delivered with iontophoresis or ultrasound to drive penetration into the active skin layers, are a powerful complement to the peel series. Vitamin C inhibits tyrosinase, the enzyme that produces melanin, and provides antioxidant protection that intercepts the UV-to-melanin signaling chain. In my Irvine studio, I often pair a vitamin C infusion treatment with gentle lactic acid peels in the same session for melasma clients, because the brightening effects of both modalities are additive.
Prescription topical treatments prescribed by a dermatologist, including hydroquinone at 4 percent, azelaic acid at 15 to 20 percent, and kojic acid, directly inhibit tyrosinase activity and are highly effective when used as part of a comprehensive protocol. These prescriptions are outside the scope of my esthetic practice but I frequently coordinate with my clients' dermatologists to ensure topical prescriptions and professional peel timing are aligned rather than working against each other.

This section matters as much as the treatment recommendations, because the wrong interventions can set melasma treatment back by months. I have seen clients come into my Irvine practice with significantly worsened melasma after aggressive treatments that were entirely inappropriate for their condition.
Melasma that develops during pregnancy, commonly called the "mask of pregnancy," is driven by the dramatic hormonal shifts of the second and third trimesters. It follows the same pattern as hormonal melasma: symmetrical patches across the cheeks, upper lip, and forehead that are often more pronounced than non-pregnancy melasma because estrogen and progesterone levels during pregnancy are significantly higher than during contraceptive use.
Treatment during pregnancy is significantly restricted. The following interventions are generally considered safe during pregnancy for melasma:
What should be avoided during pregnancy:
Many clients find that pregnancy melasma improves significantly in the months after delivery when hormone levels normalize. Some resolves completely without active treatment. Those who retain significant pigmentation post-partum can then begin a full treatment protocol without the restrictions pregnancy imposes.

The single most important reframe for melasma clients is this: melasma management is more like managing a chronic skin condition than completing a course of treatment. The underlying tendency toward melanocyte hyperactivity does not go away with successful treatment. It is present and can be reactivated at any point by the right combination of hormonal exposure and UV light.
This does not mean melasma is unmanageable. It means managing it requires an ongoing commitment to certain habits rather than a finite treatment course with a definite endpoint. The clients in my Orange County practice who maintain the best long-term results share a few consistent characteristics:
Results with this approach are genuinely good. Many clients with well-managed melasma maintain skin that looks uniformly clear without visible patches for months or years at a time. The condition has not been eliminated, it is being actively managed. That distinction, once accepted, shifts the relationship with melasma from frustrated and reactive to informed and proactive. That shift alone tends to improve outcomes because clients stop abandoning protocols the moment they see some improvement and instead maintain the habits that produced the improvement.
If you have melasma and have not yet had a clinical assessment of your specific type, depth, and severity, I would encourage you to start there. The appropriate professional treatment approach differs significantly depending on whether you have epidermal, dermal, or mixed melasma, and on your Fitzpatrick skin type. A facial consultation at Real Skin Beauty includes this assessment and gives you a realistic protocol tailored to your actual skin rather than a generic plan.
