How to Prepare for Laser Hair Removal — Complete Pre & Post Care Guide
Getting the most out of your laser hair removal sessions comes down to preparation. Following the right pre and post care steps protects your skin, improves results, and speeds up recovery. This practical checklist covers everything you need to do before and after each session at Pay & Go Laser MD Spa in Hollywood, FL.
Before Your Session: What to Do
- Shave the treatment area 24 hours before your appointment — the hair stub must be present under the skin but not above it
- Shower and cleanse the area thoroughly on the day of your session
- Arrive with clean, product-free skin — no lotions, deodorant, perfume, or sunscreen on the area
- Wear loose, comfortable clothing that gives easy access to the treatment area
- Stay well hydrated — hydrated skin conducts laser energy more evenly
Before Your Session: What to Avoid
- No waxing, threading, or tweezing for at least 4 weeks before treatment — the follicle root must be intact for the laser to target it
- No sun exposure or tanning (sunbeds, spray tans) for 2 weeks before your session
- Avoid retinol, AHAs, BHAs, and chemical exfoliants on the treatment area for 5–7 days before
- Do not use self-tanner or bronzers for at least 2 weeks prior
- Skip blood-thinning supplements (fish oil, aspirin unless prescribed) 3 days before if possible
- If you have a history of cold sores and are treating the lip area, ask us about antiviral prophylaxis
What to Expect Right After Your Session
Immediately after treatment, the skin in the treated area will feel warm — similar to a mild sunburn. You may see slight redness and minor swelling around the follicles (called perifollicular edema), which is completely normal and means the laser worked. This typically subsides within 24–48 hours. Stubble will appear to "grow" over the next 1–3 weeks — this is the treated hair being pushed out by the body, not new regrowth.
Post-Session Care: What to Do
- Apply aloe vera gel or a gentle fragrance-free moisturizer to soothe the area
- Use SPF 30+ on any treated area that will be exposed to sun
- Keep the area cool — cold compresses help with redness and discomfort in the first few hours
- Gently exfoliate (dry brush or light scrub) at week 2–3 post-session to help shed treated hairs
Post-Session Care: What to Avoid
- No hot showers, hot baths, steam rooms, or saunas for 24–48 hours — heat can irritate treated follicles
- No vigorous exercise for 24 hours (sweat can irritate freshly treated skin)
- Avoid direct sun exposure for 2 weeks after each session and always apply SPF
- Do not wax, tweeze, or thread between sessions — shaving is always fine
- Skip active skincare (retinol, AHAs) on the treated area for 5–7 days after
South Florida Tip: Sun Protection Is Non-Negotiable
In Hollywood, FL, UV exposure is year-round and intense. Treating sun-kissed skin increases the risk of hyperpigmentation, particularly for medium to dark skin tones. We always ask clients to avoid sun on treated areas and strongly recommend SPF 50 for outdoor activities. If you have an upcoming beach trip or vacation, schedule your session at least 2 weeks before or after.
Frequently Asked Questions
Should I shave before laser hair removal?
Yes — shave the treatment area 24 hours before your session. Do not shave on the same day, and never wax or tweeze before laser.
What happens if I don't shave before my laser appointment?
Surface hair can absorb laser energy that should go to the follicle, causing discomfort and reducing effectiveness. We may need to shave you in-office, which can add time to your appointment.
Can I shower after laser hair removal?
Yes, but use lukewarm water — not hot. Avoid hot showers, steam rooms, and saunas for 24–48 hours after treatment.
How long after laser can I go in the sun?
Wait at least 2 weeks after a session before direct sun exposure. Always apply SPF 30+ to treated areas. Tanned skin increases the risk of hyperpigmentation.
