Why Fitzpatrick V-VI need a different approach. The complete safety reference for IPL hair removal across all skin tones.
A 6-minute breakdown of why IPL works differently on different skin tones, the burning risk on Fitzpatrick V-VI, and how to settings-match.
IPL (Intense Pulsed Light) is one of the most popular home hair removal technologies, but it is also the one most likely to cause burns and permanent skin discoloration when used incorrectly on the wrong skin tone. This is the safety guide every IPL buyer should read before their first session.
IPL works by light energy being absorbed by melanin in the hair follicle, generating heat that destroys the follicle. The problem: melanin in your skin also absorbs the light. The more melanin in your skin (darker skin tones), the more light it absorbs – which means more heat in your skin, more risk of burns and PIH.
This is not racism in technology – it is physics. Same physics applies to white people with dark tans (which is why no recent sun exposure rule exists).
If your skin tone is naturally medium-dark to dark (Fitzpatrick IV-VI), most consumer IPL devices either: (a) will not work effectively because they reduce power too much for safety, or (b) will be unsafe if you push energy higher. Better technologies for you: diode laser (810nm) or Nd:YAG (1064nm), which target follicles deeper and bypass surface melanin.
IPL only works on hair that has melanin. White, grey, red, and very blonde hairs do not absorb enough light – IPL will not remove them. Black and dark brown hair: most responsive. Light brown: responsive but slower. Pure white, grey, red, or blonde: not effective with IPL.
Regardless of skin tone, always patch test on a 2x2cm area 48 hours before treatment. Look for: redness lasting over 24h, blistering, pigment darkening, or any persistent change. This 5-minute test prevents thousands of dollars of laser treatment to repair damage.

Patch test on a 2x2cm area of inner thigh or under the arm. Use lowest setting. Wait 48 hours minimum. Look for: any blistering (STOP), prolonged redness over 24h (reduce settings), dark spots forming (STOP – PIH risk). Test results must be clear before full treatment.
Mild pinkness 1-4 hours after treatment
What to doNormal. Apply aloe vera.
Hairs falling out 1-2 weeks after
What to doExpected - this is the result.
Sustained redness over 24 hours
What to doReduce energy by 1 level next session.
Visible burn marks (white or red blisters)
What to doApply cool compress, antibiotic ointment if blistered. Do not pick. See doctor if severe.
Dark spots appearing in treated area (PIH)
What to doStop all IPL. Strict SPF 50. Topical tyrosinase inhibitor. May take 6-12 months to fade.
Light spots (hypopigmentation)
What to doStop immediately. See dermatologist - often permanent.
Legal disclaimer
This is educational information. Consumer IPL devices have inherent risks especially for darker skin tones. If unsure of your skin type or safe settings, consult a professional dermatologist before purchase or use. LazzyBeauty machines are intended for cosmetic use; misuse can cause permanent skin damage.
Depends on your specific skin tone, not ethnicity. Take the Fitzpatrick test – many Asian and Hispanic people fall into III-IV range and can use IPL safely with proper settings. Those in V-VI range need alternative technologies.
