Spot family: what resembles what?
Solar lentigo (sun spot) are sharp-edged, flat, brown spots; they are the trace of accumulated UV damage over the years. Ephelides (freckles) are genetic and darken with sun exposure. Melasma is usually symmetrical, map-like, concentrated on the cheekbones and forehead; it is hormonal and light-dependent. PIH (post-inflammatory hyperpigmentation) is secondary pigment that develops after acne, pimples, burns, or procedures.
This distinction is important because treatment plans differ. For example, while Q-switched laser is effective for sun spots, the same laser can worsen melasma. Correct diagnosis is as valuable as treatment.
Why is melasma stubborn?
Melasma is not just a superficial pigment problem; it carries pigment and vascular components in the dermis (deep). Therefore, surface-focused treatments alone are often insufficient.
Hormonal fluctuations (pregnancy, oral contraceptives, hormone therapy), UV, and even visible light are triggers. The same patient can reset months of treatment after a short vacation. Therefore, the treatment plan is a lifestyle plan along with photoprotection.
- Mineral + iron oxide containing SPF 50+ is mandatory daily.
- Wide-brimmed hat + UV glasses.
- Topical depigmenting agents: azelaic acid, kojic acid, arbutin, tranexamic acid, niacinamide.
- Hydroquinone-containing combination formulas under medical supervision (when necessary).
- Chemical peeling: lactic, mandelic, glycolic - in controlled doses.
- Laser (low dose, perfectly suitable device, only with an experienced physician).
Clinical note:Melasma requires strategy, not tactics. Aggressive treatments promising quick results typically worsen melasma in the long run. A mature approach requires annual, not monthly, planning.
Is summer season the time for pigment treatment?
There are treatments that can be done in summer and those that should not. Mild chemical peels, low-intensity mesotherapy, certain topical protocols, and microneedling can be safely applied for specific indications.
On the other hand, laser sessions that penetrate from the surface to deeper layers, medium-deep peels, and ablative lasers are generally postponed during summer due to the risk of post-inflammatory pigmentation. The ideal calendar is between late September and early April.
Attention:The feeling of "it's over, my spots are gone" in melasma is deceptive. Stopping care after the initial fading significantly increases the risk of re-darkening. A long-term maintenance plan is essential.
Daily life recommendations
I recommend my patients view melasma like seasonal asthma: a chronic facial condition that flares up with provocation and is kept under control with management. With this framework, treatment is approached more patiently.
We accept that UV exposure cannot be eliminated; however, details such as smart clothing, hats, UV coating on windows, and discipline regarding in-car exposure dramatically reduce the total load.
Post-inflammatory hyperpigmentation (PIH)
A dark spot that forms after acne, eczema, insect bites, burns, or minor trauma is PIH. It is especially common in patients with medium to dark skin tones. Treatment primarily involves resolving the trigger (e.g., calming active acne) and supporting it with low-dose depigmenting agents.
Important principle: PIH usually fades gradually within 6-18 months. Aggressive lasers and peels can accelerate this fading while also increasing the risk of a "rebound." A patient approach is the safest approach.
Daily life recipe for pigment treatment
Morning: antioxidant serum (Vitamin C + ferulic acid) → niacinamide or tranexamic acid serum → moisturizer → mineral SPF 50+ containing iron oxide. Evening: gentle cleansing → depigmenting serum (azelaic acid or kojic acid) → retinoid (3-4 times a week, according to tolerance) → moisturizer.
Patients following this routine show measurable improvement after 3-6 months. An important warning: In patients with Asian-Mediterranean skin, especially unnecessarily strong actives can cause pigment rebound; medical follow-up is essential.
Essence of the section:Spot treatment is an area where patience is professionalized. Not the promise of a quick solution, but long-term follow-up and discipline create the real result.
