Why Preparation Matters as Much as the Treatment Itself
Laser hair removal delivers long-term smoothness, but your results depend on more than the technology. What you do before and after each session directly affects comfort, safety, and how well the laser targets unwanted hair. At 18 Spa in Loveland, our RN-led team walks every client through a clear roadmap—because informed preparation prevents complications and maximizes every pulse of light.
This guide covers the essential best practices: what to do in the weeks leading up to treatment, how to prepare your skin the day of, what happens during the session, and the aftercare steps that protect your investment.
Before Your First Session: Set Your Skin Up for Success
Stop Plucking, Waxing, and Threading (4–6 Weeks Out)
Laser hair removal targets the pigment in the hair follicle. If you’ve yanked the root out with wax or tweezers, there’s nothing for the laser to find. Shaving is fine—it leaves the follicle intact beneath the surface—but any method that removes the entire hair must stop at least four weeks before your appointment.
Avoid Sun Exposure and Tanning Products (2–4 Weeks Out)
Tanned or sunburned skin carries more melanin, which competes with the hair follicle for laser energy. This raises the risk of burns, hyperpigmentation, and poor results. Stay out of direct sun, skip the tanning beds, and pause self-tanners. If you must be outdoors, apply broad-spectrum SPF 30+ daily.
Shave the Treatment Area (24 Hours Before)
You want the hair trimmed to just below the skin surface—not long enough to singe, not so short the laser misses it. Shave the evening before or the morning of your session. Use a clean razor and avoid irritating the skin with aggressive scrubbing.
Skip Certain Skincare Ingredients (3–7 Days Before)
Retinoids, glycolic acid, salicylic acid, and benzoyl peroxide can thin or sensitize your skin. Pause these products on the treatment area for three to seven days before your appointment. Stick to gentle cleansers and fragrance-free moisturizers.
Arrive with Clean, Bare Skin
No lotions, deodorants, makeup, or perfumes on the day of treatment. Residue can interfere with the laser and increase irritation. Shower beforehand and wear loose, comfortable clothing that won’t rub the treated area afterward.
What to Expect During Your Laser Hair Removal Session
You’ll be guided to a private treatment room where your technician will review your medical history, skin type, and hair characteristics. The laser settings are calibrated to your unique profile—this is why medical oversight matters.
The technician will apply a cooling gel or use a device with a built-in cooling tip to protect your skin. You’ll feel a series of quick pulses—most clients describe it as a rubber band snap or warm pinch. Discomfort varies by area: underarms and bikini zones tend to be more sensitive than legs or arms.
Sessions range from 10 minutes for the upper lip to 45 minutes for full legs. You’ll leave the same day with no bandages or downtime, though your skin may look pink or feel warm for a few hours.
Immediate Aftercare: The First 24–48 Hours
Cool and Soothe
Apply a cold compress or aloe vera gel if you notice redness or mild swelling. Avoid hot showers, saunas, steam rooms, and vigorous exercise for 24 hours—heat can aggravate inflammation.
Skip Active Ingredients
Hold off on retinoids, acids, and exfoliants for at least 48 hours. Your skin is temporarily more sensitive, and harsh products can trigger irritation or post-inflammatory pigmentation.
Protect from the Sun
Treated skin is vulnerable to UV damage. Apply SPF 30+ every morning and reapply every two hours if you’re outdoors. Wear a hat or cover the area with clothing when possible.
Don’t Pick or Scratch
You may notice hair “shedding” over the next 7–14 days as the treated follicles release the damaged hair. This is normal. Let it fall out on its own—picking or scrubbing can cause ingrown hairs or scarring.
Ongoing Care Between Sessions
Shave as Needed
Between appointments, shaving is the only hair removal method you should use. Avoid waxing, plucking, threading, or depilatory creams—they disrupt the follicle cycle and reduce the effectiveness of your next laser session.
Moisturize Daily
Keep the skin hydrated with a fragrance-free lotion. Healthy, well-moisturized skin responds better to treatment and heals faster.
Maintain Sun Protection
UV exposure between sessions can cause hyperpigmentation and limit your treatment options. Make daily SPF a non-negotiable habit.
Schedule Sessions on Time
Hair grows in cycles, and the laser only works on follicles in the active growth phase. Most clients need sessions every 4–8 weeks, depending on the area. Sticking to your schedule ensures you catch each cycle and achieve the smoothest results.
Laser Hair Removal Best Practices for Loveland Clients
Northern Colorado’s high altitude and intense sun make sun protection even more critical. UV exposure is stronger here, and even brief outdoor time can compromise your results or increase side effects. Plan your treatment series during fall or winter if possible, and always carry SPF in your bag.
If you’re active outdoors—hiking, biking, or spending time at the lake—schedule sessions when you can avoid direct sun for at least 48 hours post-treatment. Communicate your lifestyle with your provider so they can adjust timing and settings accordingly.
What Not to Do: Common Mistakes That Sabotage Results
- Skipping the consultation. Every skin type and hair color requires different settings. A one-size-fits-all approach increases risk and reduces effectiveness.
- Tanning between sessions. Even one sunburn can delay your next appointment by weeks.
- Using numbing creams without approval. Some topical anesthetics interfere with laser penetration or cause adverse reactions. Always ask first.
- Expecting instant results. Hair sheds gradually over 1–2 weeks, and you’ll need multiple sessions to target all growth cycles.
- Ignoring aftercare instructions. Skipping SPF or using harsh products can lead to burns, scars, or uneven pigmentation.
How to Choose a Provider You Can Trust
Laser hair removal is a medical procedure. Look for a clinic with licensed medical professionals—registered nurses or physicians—who perform or directly supervise treatments. Ask about the type of laser used (different devices work better for different skin tones), how settings are customized, and what happens if you experience a side effect.

Frequently Asked Questions
How many sessions will I need for full results?
Most clients need 6–8 sessions spaced 4–8 weeks apart, depending on the treatment area and hair growth cycle. Hormonal factors, genetics, and hair color all influence the timeline. Maintenance sessions once or twice a year may be needed to address any regrowth.
Can I wear makeup or deodorant after facial or underarm treatment?
Wait at least 24 hours before applying makeup, deodorant, or any scented products to treated skin. These can clog pores or irritate the area while it’s healing. Stick to gentle, fragrance-free products during the first 48 hours.
What should I do if I notice blistering or severe redness?
Mild redness and warmth are normal and typically fade within a few hours. If you develop blisters, intense pain, or prolonged swelling, contact your provider immediately. Applying ice and avoiding sun exposure can help, but medical guidance ensures proper healing and prevents scarring.
