How to Even Out Skin Tone: Sun Spots, Marks and Melasma
Uneven skin tone usually comes from sun, old breakout marks or melasma. Start with daily tinted SPF, add vitamin C and niacinamide, and give spots months.
Key takeaways
- Uneven skin tone usually comes from sun, marks left after breakouts, melasma or redness, and one face can show several.
- Darker skin tones are more prone to marks after breakouts, and visible light can deepen pigment in them.
- Daily broad-spectrum SPF 30 or higher, tinted with iron oxide, is where the AAD starts for dark spots in medium to dark skin.
- In controlled studies, vitamin C helped limit new pigment from daylight and niacinamide made spots look lighter than a plain moisturizer.
- Per the AAD, spots a few shades darker than your skin usually fade within 6 to 12 months; changing spots need a dermatologist.

Uneven skin tone means patches that look darker, lighter or redder than the skin around them, such as sun spots, breakout marks or melasma. To even it out at home, wear broad-spectrum sunscreen daily, add a vitamin C or niacinamide serum and keep irritation low. Most dark spots take several months to fade.
Our routine pairs Radiant C-F Glow Drops, our vitamin C + ferulic serum, in the morning with Texture Refining Treatment, our 10% niacinamide serum, at night.
What causes uneven skin tone?
Uneven skin tone usually comes from melanin, the skin's brown pigment, building up in some areas more than others. Years of sun, marks left behind after acne or irritation, and hormone-related melasma are the common causes. Redness from flushing or sensitive skin can also make a complexion look patchy, and one face can show more than one cause.
Melasma has its own triggers, including sunlight, pregnancy hormones, birth control pills, some medicines and thyroid disease, and it is much more common in women than in men (AAD, 2022).
Darker skin is more prone to marks after a pimple, bite or rash. A review describes this postinflammatory hyperpigmentation as more frequent and more severe in darker skin (Davis & Callender, 2010).
In 1,412 visits at a New York skin of color center, uneven pigment was among the five most common diagnoses for Black patients and missing from the top 10 for white patients (Alexis et al., 2007).
Rough bumps and visible pores are a texture problem rather than a color one; our guide to skin tone and texture covers those.
Which type of uneven skin tone do you have?
The type of uneven tone decides what helps first. Flat brown spots on sun-exposed skin usually come from years of sun, and flat marks where a breakout healed are post-blemish marks. Tan to gray-brown patches on the cheeks, forehead, chin or upper lip suggest melasma, while redness that flushes or stings points to sensitive skin or rosacea.
| What you see | Likely cause | What to start with |
|---|---|---|
| Small flat brown spots where sun hits | Sun exposure over years | Daily SPF 30+, vitamin C in the morning, niacinamide at night |
| Flat dark marks where pimples healed | Postinflammatory marks | Calm the breakouts first, SPF, gentle actives, hands off |
| Tan, brown or gray-brown patches on cheeks, forehead, chin or upper lip | Possibly melasma (AAD, 2022) | Tinted SPF with iron oxide and a dermatologist visit |
| Redness that flushes, stays or stings | Sensitive skin or rosacea (AAD, 2024) | Fragrance-free basics and a dermatologist visit |
Why is sunscreen the first step for an even tone?
Sunscreen comes first because sunlight keeps making new pigment that a serum alone cannot keep up with. In its guide for medium to dark skin tones, the American Academy of Dermatology says effective treatment for dark spots "begins with sunscreen": SPF 30 or higher, broad-spectrum, tinted with iron oxide and reapplied every two hours (AAD, 2025).
The tint matters for darker skin, because iron oxide blocks visible light. Researchers shone visible light on the backs of 20 people with skin types IV to VI, and the pigment was darker and lasted longer than pigment from long-wave UVA, while skin type II showed none (Mahmoud et al., 2010).
In 68 people with melasma who all used the same prescription cream, the group given an iron oxide sunscreen improved 28% more on color measurements than the UV-only group (Castanedo-Cazares et al., 2014).
Daily SPF may help on its own: in an uncontrolled one-year study of 32 adults, run by Johnson & Johnson researchers, mottled pigmentation was among the most improved signs (Randhawa et al., 2016).
Vitamin C or niacinamide: which fades dark spots?
Vitamin C and niacinamide both have controlled studies behind them, and they do different jobs. Vitamin C reduced the pigment that daylight-like UV added, while niacinamide made existing spots look lighter than a plain moisturizer did. Many routines use vitamin C in the morning and niacinamide at night, and a dermatologist may add azelaic acid or a retinoid.
| Ingredient | Study | What was measured | Caveat |
|---|---|---|---|
| Vitamin C | 31 trials, 741 volunteers (de Dormael et al., 2019) | Less pigment after daylight-simulated UV; dose-dependent, strong effect at 10% | All authors from L'Oréal; tested prevention, not fading old spots |
| Niacinamide 5% | 18 women, paired design (Hakozaki et al., 2002) | Less visible hyperpigmentation than vehicle after 4 weeks | Small; P&G authors; Japanese women |
| Niacinamide 5% | 50 women aged 40 to 60, split-face (Bissett et al., 2004) | Better spots, red blotchiness and sallowness than control at 12 weeks | P&G authors; white women only |
| Azelaic acid, retinoids | Review (Davis & Callender, 2010) | Listed among options for marks after inflammation | Can irritate; ask a dermatologist |
In Hakozaki's trials (Hakozaki et al., 2002), the authors reported that niacinamide "significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use." Our serum uses 10%, a higher dose than the 2% and 5% tested.
What these studies did not test:
- Our finished serums, or vitamin C and niacinamide used together.
- Melasma as a cosmetic routine without a prescription cream.
- Long-term results in deeper skin tones for niacinamide.
What does an even-tone routine look like, step by step?
A routine to even out skin tone takes about ten minutes a day: vitamin C and sunscreen in the morning, niacinamide and moisturizer at night. Introduce one new product at a time, start niacinamide once a day if your skin is sensitive, and give it several months before you judge it.
- Cleanse gently, morning and night. Use a mild cleanser and lukewarm water. Skip scrubs and anything that stings.
- Apply vitamin C in the morning. Press a few drops of Radiant C-F Glow Drops into dry skin on the face and neck.
- Work the serum in with GlowLift™ Infinity. Glide our GlowLift™ Infinity face sculpting device upward and outward: warm mode 2 minutes, cold mode 2 minutes, then EMS along the jaw for 2 minutes, starting on Level 1.
- Repeat the GlowLift™ step 5 to 7 times a week. It works your serum in and leaves a de-puffed, more sculpted-looking finish. It does not fade spots.
- Finish with tinted SPF 30 or higher. Use a broad-spectrum formula with iron oxide and reapply every two hours outdoors.
- Use niacinamide at night. Apply Texture Refining Treatment, then moisturizer.
Do not use an EMS device if you are pregnant or have a pacemaker, implanted defibrillator or other active electronic implant, or on broken, irritated or infected skin. If you have epilepsy or a diagnosed skin condition, check with your doctor first.
GlowLift™ should not be used over a skin cancer or where you have a history of skin cancer, and anyone with a photosensitive condition should ask a doctor first.
How long does it take for dark spots to fade?
A dark spot a few shades darker than your skin usually fades within 6 to 12 months, according to the American Academy of Dermatology's guide for darker skin tones (AAD, 2025). Deeper marks that look slate blue, gray or very dark brown can take years. New sun and new irritation add pigment back.
Irritation slows things down. The review on postinflammatory marks advises caution with every treatment, because irritation can make the marks worse (Davis & Callender, 2010). That is why the routine uses gentle cleansing, one new product at a time and no scrubbing or picking.
The same AAD guide warns that some products imported from other countries may contain undisclosed steroids or mercury, and that liquid bleach should never go on skin (AAD, 2025).
Which dark spots need a doctor rather than a serum?
See a board-certified dermatologist if a spot is changing, itching or bleeding, or if it has an uneven border, several colors or is larger than 6 millimeters (smaller spots can still be a concern). Also book a visit for patches that suggest melasma, redness that persists, or spots that have not improved after a few months of daily care.
These signs follow the AAD's ABCDE guide to melanoma warning signs (AAD). A dermatologist can confirm what a spot is and offer prescription creams, peels or laser if needed.
Our serums are cosmetic and do not treat pigment disorders. For product questions, use our contact form.
The bottom line
Uneven skin tone comes from sun, breakout marks, melasma or redness, and evening it out starts with daily tinted SPF 30 or higher. Add vitamin C in the morning and niacinamide at night; a spot a few shades darker than your skin usually takes 6 to 12 months to fade. Start with sunscreen over Radiant C-F Glow Drops.
Small daily habits like these are what we mean by skin longevity.
