What Are Fitzpatrick Types IV, V, and VI?

VIDeep brown to blackAlmost never burnsAlways tans

Many East and Southeast Asians — including many Koreans and Japanese — fall within Type IV. South Asian and Latin American populations span IV to V. African and African-descended populations are predominantly V to VI.


The Core Skin Science of Types IV–VI

Melanin is abundant. A higher ratio of eumelanin (brown/black) means:

  • Strong UV protection and lower skin cancer risk
  • Slower photoaging — wrinkles and firmness loss develop more gradually
  • However, significantly higher vulnerability to pigmentation issues

Key Skin Concerns for Types IV–VI

PIH (Post-Inflammatory Hyperpigmentation)
Brown to dark marks left behind after acne, wounds, or irritation. Types IV–VI produce significantly more melanin in response to the same inflammatory trigger as lighter skin. PIH is harder to treat and slower to fade in these types.
Melasma
More prevalent in Types IV–VI, especially women. Pregnancy, oral contraceptives, and UV exposure are major triggers. Melasma recurs rapidly without consistent sun protection even during treatment.
Keloids and Hypertrophic Scars
Types V and VI have higher rates of keloid formation — excessive scar tissue growth. Manual acne extraction and post-procedure skin care require extra care.

Brightening and Pigmentation Ingredients for IV–VI

IngredientKey PropertiesNotes
NiacinamideLow irritation, high safety margin4–10%
Tranexamic acidEffective for melasma and PIH2–5%
Azelaic acidBrightening + anti-inflammatory10–20%
ArbutinGradual brightening1–2%
Kojic acidEffective but irritating at high concentrations0.5–1% in gentle formulas

Retinol note: Effective for PIH improvement, but irritation itself can trigger more PIH. Start at the lowest available concentration and increase very gradually as skin tolerates it.


Sunscreen: The White Cast Problem

For Types V and VI, standard mineral sunscreens (zinc oxide and titanium dioxide) leave an obvious white cast that makes daily use impractical.

Chemical Sunscreens First
Chemical filters — avobenzone, octinoxate, oxybenzone — leave no white cast. Choose broad-spectrum products that cover both UVA and UVB.
Tinted Mineral Sunscreens
Nano-formulated zinc oxide or tinted mineral sunscreens eliminate the white cast. When actively treating melasma or PIH, pairing chemical filters with a tinted mineral provides excellent coverage and UV protection.

Frequently Asked Questions

Is it true that darker skin doesn't need sunscreen?
No. Types IV–VI have lower skin cancer risk than I–II, but not zero. More importantly for daily skin health, UV directly worsens melasma and PIH — if pigmentation is a concern, consistent sunscreen use is essential. SPF 30+ every day is recommended.
Will PIH eventually fade on its own?
In Types IV–VI, PIH can take months to years to fade naturally. Combining brightening actives (niacinamide, tranexamic acid) with daily sun protection significantly accelerates clearance compared to waiting alone.
