IPL Hair Removal Aftercare: Do's and Don'ts for Best Results

Why aftercare is half the results equation

It's easy to focus entirely on the IPL device itself and treat aftercare as an afterthought, but how you treat your skin in the hours and days after a session has a real effect on both your comfort and how well your results hold up over time. IPL works by heating the melanin in hair follicles, and that process leaves skin temporarily warm, slightly sensitised, and more vulnerable to irritation — so the goal of aftercare is simply to protect skin while it settles back to normal and let the treated follicles do their work undisturbed.

Right after your session: what to do

Apply a fragrance-free, soothing moisturiser or aloe vera gel to calm any warmth or mild redness, which is a completely normal short-term reaction for many people. A cool (not ice-cold) compress can help if an area feels particularly warm. Keep the treated area clean and let it breathe in loose, breathable clothing for the rest of the day, especially if you've treated underarms, legs, or the bikini line where fabric tends to rub.

Right after your session: what to avoid

Skip hot showers, saunas, steam rooms, and strenuous exercise for at least 24 hours, since heat and sweating can aggravate already-warmed skin. Avoid direct sun exposure on the treated area and always apply a high-SPF sunscreen if you can't avoid being outside — sun-exposed, treated skin is more prone to pigmentation changes. It's also best to hold off on active skincare ingredients like retinoids, AHAs/BHAs, and fragranced products on the treated area for a couple of days, and don't wax, pluck, or use depilatory creams between sessions, since IPL specifically needs the hair root intact to target it.

The first 24 to 48 hours

Mild redness or a sensation similar to mild sunburn is common and typically settles within a few hours to a day. Continue moisturising twice daily and keep sun protection consistent even after the initial redness fades, since skin can remain slightly more photosensitive for a few days. Shaving is generally fine and is actually the recommended way to remove hair between sessions once any initial sensitivity has settled, as it doesn't disturb the follicle the way waxing does.

Getting the most out of the weeks between sessions

Hair doesn't fall out immediately — treated hairs typically shed gradually over one to three weeks as the follicle's growth cycle is disrupted, so don't be discouraged if you still see hair a few days after treatment. Most routines call for a session roughly every two to four weeks initially, tapering off as regrowth slows, so spacing sessions consistently with a device like the DermaSilk IPL Hair Remover and following the aftercare steps above each time gives the treatment its best chance to work cumulatively rather than starting from scratch every time.

When to stop and seek advice

Occasional mild redness or warmth is expected, but you should stop using the device and speak to a dermatologist or doctor if you notice blistering, persistent pain, unusual pigment changes (either darker or lighter patches that don't fade), or any signs of infection such as swelling, pus, or increasing warmth in the area. People with very dark skin tones, very light or grey hair, active tans, or certain skin conditions or medications that increase photosensitivity should check with a professional before starting IPL at all, and always do a patch test on a small area first. This guide is general buyer information, not medical advice — if in doubt, get professional guidance before continuing any hair removal treatment.

The bottom line on IPL aftercare

Good aftercare isn't complicated — moisturise, protect from sun and heat, leave active ingredients alone for a couple of days, and let hairs shed naturally rather than plucking or waxing between sessions. It takes a few extra minutes per session, but it's the difference between skin that tolerates a full treatment course comfortably and skin that ends up irritated before you've even seen the results IPL is capable of.
