Melasma Treatment Guide: Causes, Remedies & Skincare Tips

Dealing with those annoying dark patches on your skin? Well, you’re not alone. It affects millions, and it can be frustrating, but the good news is that with the right approach, you can significantly improve its appearance. In this guide, we will discuss the causes and solutions of dark patches, highlight effective at-home melasma treatments, and share dermatologist-recommended solutions for melasma, so you can feel confident again.

What Causes Melasma?

Melasma goes deeper than the surface. Here’s what lies beneath the surface:

Hormones: Whether from pregnancy, birth control, or hormone replacement therapy, estrogen can increase, signaling the body to produce pigment.

Sun Exposure: UV exposure triggers melanocytes (the cells that produce pigment), and the sun will exacerbate the patches. Even 10 minutes of sun per day is enough to worsen melasma!

Genetics: According to a global survey, 48% of people with this discoloration report a family history.

Heat & Pollution: There is new evidence to suggest that airborne pollutants may increase facial pigmentation in urban areas.

Thyroid Disease: It has been linked to a four-fold increase in melasma cases, supporting the idea that hormonal and pigmentation changes contribute to the condition

Professional Tips: Wear a wide-brimmed hat and stay in the shade whenever possible—even if it’s cloudy!

Dermatologist-Approved Treatments for Melasma

You don’t always need to apply very intense treatments for melasma. Dermatologists suggest using mild but effective ingredients that have science to support them:

Niacinamide

Niacinamide inhibits melanin production, which makes it an excellent option for uneven skin tone.

Azelaic acid

In a 2023 clinical study, azelaic acid was shown to reduce melanin in affected patients.

Kojic acid

A naturally occurring skin-lightener made from a mushroom byproduct that inhibits melanin production.

Tranexamic acid

A 2024 new study has shown that txa will significantly reduce melasma in patients when applied topically, with a mechanism of decreasing melanin production.

Furthermore, don’t forget to use sunscreen as well. UV rays can activate melasma or, ironically, even make it worse. Daily application of at least SPF 50 each morning is important. A 2020 study reported that applying sunscreen daily contributed to decreased melasma recurrence among patients.

Natural Remedies for Melasma

If you’d like a gentler approach or want to help treat your melasma more naturally, consider trying these at-home DIY treatments:

1. Turmeric Yogurt Mask:

Mix ½ tsp turmeric into 1 tbsp plain yogurt. Apply for 10 minutes two times per week. Turmeric has anti-inflammatory and skin-lightening properties that may help with dark patches.

2. Aloe Vera Gel:

Apply freshly extracted aloe vera to the affected area nightly. Aloe vera is known for its soothing and healing properties, and research agrees.

3. Diluted Apple Cider Vinegar (ACV) Toner:

Combine 1 part ACV with 3 parts water. Dab gently with a cotton pad. ACV is mildly exfoliating and may help lighten skin over time.

Note: Remember to patch test before applying DIY recipes, do not use acids or exfoliants the same day.

Ingredients to Avoid

Several skin-care items can aggravate melasma due to irritation of the skin and/or increase a person’s sensitivity to the sun. These include

1. Hydroquinone (without medical supervision)
2. Physically harsh scrubs
3. Fragranced skin-care products
4. Avoid over-exfoliating
