What causes melasma and sun damage
Pigment in the skin is produced by melanocytes, cells in the lowest layer of the epidermis that release melanin in response to signals from light, heat, hormones and inflammation. Both melasma and sun damage are the result of melanocytes being over-stimulated, but by different triggers and with different patterns.
- Melasma presents as symmetric, blotchy brown or gray-brown patches on the cheeks, forehead, upper lip, nose and jawline. It is driven by estrogen and progesterone (pregnancy, hormonal contraception and hormone therapy are common triggers), by UV and visible light, and by heat. Genetics and skin tone matter; it is more common in women and in medium to deeper complexions. Pigment can sit in the epidermis, the dermis or both, and dermal melasma is slower to respond.
- Sun spots (solar lentigines) are discrete, well-defined flat spots that accumulate on sun-exposed areas: the face, chest, shoulders and hands. They reflect cumulative UV exposure over decades.
- Photodamage more broadly includes uneven tone, dullness, roughness, fine lines and broken capillaries as UV breaks down collagen and elastin in the dermis.
Scottsdale sits at a high UV index for most of the year, with intense visible light and heat that keep melanocytes active even when you are not “tanning.” Windshield glass, morning walks and patio dinners all count. This is why we treat melasma as a condition to be managed rather than a spot to be removed.
How we assess pigmentation
Jessica Lee, MSN, FNP-C, evaluates the pattern, color and border of your pigment to distinguish melasma from lentigines and post-inflammatory marks, and to estimate how deep it sits. She reviews hormonal history, medications, current skincare and sun habits, and assesses your skin tone and sensitivity to gauge peel tolerance and pigment risk. If a spot has irregular features that warrant medical evaluation, she will refer you to dermatology before any cosmetic treatment.
The plan that follows is deliberately staged. Skin is usually prepared with medical-grade skincare for a few weeks before the first peel, which both improves the peel result and lowers the risk of rebound darkening.
Treatment options for melasma and sun damage
| Treatment | Best for | Sessions | Onset | Downtime |
|---|---|---|---|---|
| VI Peel | Melasma, sun spots, uneven tone, dullness, post-inflammatory marks | Series of 2–4, about 4 weeks apart, then maintenance | About 1 week after each peel | 3–7 days of peeling |
| Medical-grade skincare | Preparing skin, suppressing melanin, preventing recurrence | Daily, ongoing | 8–12 weeks | None; mild dryness possible |
| SkinPen microneedling | Sun-damaged texture, fine lines, dullness; selective use with controlled melasma | 3–6, 4–6 weeks apart | Progressive over the series | 1–3 days of pinkness |
VI Peel is the centerpiece. It is a medium-depth, medical-grade peel formulated to lift pigmented cells, brighten and help regulate melanin production, and it is appropriate for a wide range of skin tones when skin is prepared and protected. Peeling begins around day three and finishes within about a week. Melasma is typically treated as a series, with results building over two to three months. Read how the VI Peel works and what the week after looks like.
Medical-grade skincare is not an add-on; for melasma it is half the treatment. A regimen usually includes a tyrosinase inhibitor to slow melanin production, a retinoid or exfoliant to speed cell turnover, antioxidants, and a daily tinted mineral sunscreen that blocks visible light as well as UV. We recommend specific products at your consultation and adjust as your skin responds.
Microneedling is chosen carefully here. SkinPen microneedling excels at the collagen loss, fine lines and rough texture of sun damage, and it can help brightening products penetrate. Because melasma can flare with inflammation, we typically reserve it until pigment is controlled, and use conservative settings.
What to expect and a realistic timeline
- Consultation. Diagnosis of pigment type and depth, review of triggers, and a written plan with pricing. Any suspicious lesion is referred first.
- Weeks 1–4: preparation. Medical-grade skincare and rigorous sun protection begin. Skin becomes more even and better tolerates the peel.
- Month 2: first peel. VI Peel in the studio, about 30 minutes, followed by a week of peeling at home with a simple aftercare kit.
- Months 3–5. Additional peels roughly monthly as needed. Pigment lightens progressively; sun spots and dullness usually respond first.
- Maintenance. A peel every few months, especially after summer, and a skincare routine you can actually keep up. Microneedling is added for texture when appropriate.
Living with melasma in Scottsdale
We will not tell you melasma is gone for good, because it is not that kind of condition. What we can do is bring it under control, brighten sun-damaged skin considerably, and give you a routine that holds the result through an Arizona summer. Every visit is with the same nurse practitioner, so the plan is adjusted to how your skin actually behaves rather than to a protocol. That is what enhancing, not altering, looks like for pigment.
