• What you do in the 24–48 hours after an IPL session matters almost as much as the session itself — poor aftercare is one of the most common reasons people experience unnecessary irritation or PIH.
  • The immediate priority after any session: cool and soothe the treated area, avoid heat for 24–48 hours, and apply SPF to any area that will see sunlight.
  • The biggest aftercare mistake for Pakistani skin is skipping sunscreen between sessions — sun exposure on recently treated skin is the leading cause of post-inflammatory hyperpigmentation.
  • Don't wax, thread, or use depilatory creams between sessions — shaving is the only hair removal method that's safe to use on IPL-treated skin in the interim.
  • Aftercare is not optional — it's what protects your results and keeps your skin healthy across a multi-month treatment course.

Most people think about IPL in terms of the session itself — the settings, the technique, the device. What happens after is given far less attention, which is a shame because aftercare is where a lot of unnecessary irritation, pigmentation, and disappointing results actually originate. The Lux Skins lays out exactly what to do in the 24–48 hours after every IPL session, what to avoid between sessions, and how to maintain your skin's health across a full treatment course — with specific focus on what Pakistani and brown skin tones need most.

Immediately After Your IPL Session (First 2 Hours)

Cool and Soothe the Treated Area

The skin immediately after IPL is warm, mildly inflamed at the follicle level, and more reactive than usual. Your first priority is to calm that inflammation and restore the skin's comfort.

Apply one of the following to the treated area immediately after your session:

  • Aloe vera gel (pure, fragrance-free) — the most effective and widely available soothing option. Keep it in the fridge between sessions for an extra cooling effect.
  • Fragrance-free moisturiser — a simple, no-frills hydrating lotion without active ingredients, essential oils, or fragrance
  • A cool (not cold) damp cloth — gentle compression on the treated area for a few minutes reduces heat and immediate redness

Avoid anything with active ingredients — retinoids, AHAs, BHAs, vitamin C, or niacinamide — directly on the treated area immediately after a session. These ingredients increase skin reactivity and can worsen irritation on freshly treated skin.

What's Normal to See Right After Treatment

Mild redness, warmth, and slight swelling around individual follicles (similar to tiny goosebumps) are completely normal and usually resolve within 1–2 hours. These are signs the device activated the follicles — not signs of a problem. If redness and warmth fade within a few hours, everything is as expected.

If redness worsens rather than fades, or if you see blistering, these are signs to consult our IPL side effects guide and consider adjusting your intensity settings for the next session.

The First 24–48 Hours After Treatment

This window is when the skin is most vulnerable to additional irritation, so a few specific avoidances matter:

Avoid Heat Sources

Heat adds to the thermal load the skin is already managing from the IPL session. For 24–48 hours after treatment, avoid:

  • Hot showers or baths — use lukewarm water instead
  • Saunas, steam rooms, or hot tubs
  • Intense exercise that raises body temperature significantly and causes heavy sweating on the treated area
  • Heating pads or hot water bottles applied near treated areas

Avoid Tight or Friction-Causing Clothing

On treated areas like the underarms, bikini line, or inner thighs, tight clothing creates friction on skin that's already slightly sensitised. Wear loose, breathable cotton clothing for the first 24 hours after treating these areas.

Avoid Direct Sun Exposure

This is the most important avoidance for Pakistani and brown skin tones specifically. Freshly IPL-treated skin has reduced protection against UV radiation, and sun exposure on treated skin significantly raises the risk of post-inflammatory hyperpigmentation (PIH) — the darkening of the skin that can occur when melanin-rich skin is irritated. Apply SPF 30 or higher to any treated areas that will be exposed to sunlight, and reapply every 2 hours if you're outdoors.

Avoid Active Skincare Ingredients

For 24–48 hours after treatment, keep active skincare ingredients away from treated areas:

  • Retinoids / retinol — increase skin cell turnover and reactivity
  • AHAs and BHAs (glycolic acid, salicylic acid, lactic acid) — exfoliating acids that increase sensitivity
  • Vitamin C serums — can cause irritation on compromised skin
  • Benzoyl peroxide — too drying and reactive for freshly treated skin

Plain moisturiser, aloe vera gel, and SPF are all you need in the immediate post-treatment window. Resume your regular skincare routine after 48 hours.

Avoid Deodorant on Treated Underarms

If you've treated your underarms, avoid applying deodorant or antiperspirant for at least 24 hours after the session. The skin is more permeable and reactive after treatment, and deodorant ingredients can cause irritation or a reaction that wouldn't happen on untreated skin.

Between Sessions: Ongoing Aftercare

The period between sessions matters as much as the immediate post-treatment window. A few habits maintained consistently between sessions protect your results and your skin throughout the treatment course.

Sunscreen — Every Single Day on Treated Areas

This cannot be overstated for Pakistani skin. Sun exposure between sessions is the single leading cause of IPL-related pigmentation issues in medium-to-deep skin tones. Melanin-rich skin responds to UV exposure by producing more melanin — and recently IPL-treated skin, where melanin has been disrupted at the follicle level, is more prone to uneven melanin production in response to sun.

Apply SPF 30+ every morning to any treated areas that will be exposed to the sun — legs, arms, face, décolletage. Reapply every 2 hours during outdoor activities. This isn't just post-treatment advice; it should be a consistent habit throughout your entire IPL treatment course.

Shave for Interim Hair Management

Between sessions, the only hair removal method safe to use on IPL-treated skin is shaving. Waxing, threading, epilating, and depilatory creams all remove or damage the hair root — which is exactly what IPL needs to target in your next session. Using any of these between sessions essentially resets the follicle and reduces the effectiveness of your next treatment.

Shave when needed between sessions, and shave again 12–24 hours before each new session.

Gentle Moisturising Daily

Keep treated areas moisturised between sessions with a plain, fragrance-free moisturiser. IPL causes minor repeated disruption to the skin barrier at the follicle level across sessions, and consistent moisturising keeps that barrier healthy and the skin better able to respond to each treatment without excessive irritation.

Let Hair Shed Naturally

In the 1–3 weeks following each session, you'll notice hairs being expelled from the follicle — this looks like regrowth but is actually the treated follicle shedding the hair. Don't wax or pick at this shedding hair. It will fall out on its own, and interfering with it increases irritation risk. You can gently exfoliate the area with a soft washcloth to help hair shed more cleanly, but don't use a harsh scrub or mechanical exfoliant.

Aftercare for Specific Body Areas

Face (Upper Lip, Chin, Jawline)

Facial skin needs the most careful aftercare because it's the most visible and the most reactive. After treating the face:

  • Use a gentle, fragrance-free micellar water to clean the area rather than a foaming cleanser for the first 24 hours
  • Apply a lightweight, non-comedogenic moisturiser rather than a heavy cream
  • SPF is non-negotiable the morning after facial treatment and every morning during your treatment course
  • Avoid makeup on treated facial areas for at least 24 hours — if you must use makeup, choose mineral-based formulas with minimal irritating ingredients

Underarms

  • Avoid deodorant for 24 hours
  • Wear loose sleeveless tops or avoid tight sleeves on the treated side
  • Don't shave for 48 hours after treatment to let the skin settle before introducing razor friction

Bikini Line

  • Wear loose cotton underwear for 24–48 hours after treatment
  • Avoid swimming pools or the sea for 24 hours — chlorinated or salt water on recently treated sensitive skin can cause irritation
  • Avoid tight exercise clothing on the area for the first day

Legs and Arms

  • Avoid hot baths for 24 hours; use the shower instead
  • If you've treated legs, avoid wearing very tight jeans or leggings for the first day
  • Apply SPF if legs or arms will be exposed to sunlight after treatment — particularly important in Pakistan's sunny climate

Building Your Post-IPL Skincare Routine

If you want a simple routine that works alongside your IPL treatment course, here's what to do:

Morning (day after treatment):

  • Gentle fragrance-free cleanser
  • Lightweight fragrance-free moisturiser
  • SPF 30+ on all treated areas

Evening (day after treatment):

  • Gentle cleanser
  • Plain moisturiser — no actives for 48 hours after treatment

Morning (from day 3 onwards):

  • Resume your normal skincare routine
  • Keep SPF on treated areas every morning throughout the treatment course

Frequently Asked Questions

Can I moisturise after IPL hair removal?

Yes — moisturising after IPL is recommended and beneficial. Use a plain, fragrance-free moisturiser or aloe vera gel on the treated area immediately after and daily between sessions. Avoid active ingredients like retinoids, AHAs, or vitamin C on the treated area for 48 hours after each session.

How long after IPL can I shower?

You can shower shortly after an IPL session, but use lukewarm rather than hot water for the first 24 hours. Hot water adds heat to skin that's already been thermally stimulated, which can extend or worsen post-treatment redness and irritation.

Can I use retinol after IPL?

Wait at least 48 hours after an IPL session before applying retinol or retinoids to the treated area. Retinoids increase skin cell turnover and photosensitivity, which can cause unnecessary irritation on recently treated skin. Resume retinol as normal after the 48-hour window.

Conclusion: Aftercare Protects Everything You Worked For

Every IPL session is an investment in your long-term results — and aftercare is what protects that investment. For Pakistani and brown skin tones especially, consistent SPF use between sessions and avoiding heat and active ingredients in the immediate post-treatment window are the habits that determine whether your results are smooth and even or complicated by unnecessary pigmentation or irritation.
