Most patients focus all their energy on what happens during laser hair removal and very little on what happens before it. That is understandable, but preparation matters. What you do in the weeks and days before your appointment directly affects how safe your treatment is, how comfortable it is, and how effective your results will be.
At Institute for Ageless Living in Longmont, Colorado, we use the Motus AZ+ laser system for hair removal, a platform known for its efficacy across all skin tones including darker complexions. Here is the complete preparation guide for your first appointment and all subsequent sessions.

Why Preparation Matters for Laser Hair Removal
Laser hair removal works by targeting melanin in the hair follicle. The laser energy is absorbed by the pigment in the hair shaft and follicle, heating and disabling the follicle's ability to produce new hair. For this process to be both safe and effective, several conditions need to be in place:
- The hair follicle must contain a hair shaft with melanin for the laser to target
- The surface of the skin must be clear of substances that could absorb laser energy incorrectly or unpredictably
- The skin should not be recently tanned, as excess surface melanin increases the risk of unwanted thermal effects on the skin rather than the follicle
- Certain medications and supplements must be avoided to prevent photosensitivity reactions
Each of the preparation steps below addresses one or more of these conditions. Skipping preparation steps does not just affect comfort; it can compromise results and increase the risk of side effects.
4 to 6 Weeks Before Your Appointment
Stop Waxing, Plucking, and Threading
This is the most critical preparation step. Waxing, plucking, and threading remove the hair shaft and root from the follicle, leaving no melanin target for the laser to heat. Laser hair removal only works when the hair follicle contains an intact hair shaft. You must stop all root-removal hair removal methods at least 4 to 6 weeks before your first laser session, and for the entire duration of your treatment series between sessions.
Shaving is the only acceptable hair removal method during your laser hair removal treatment series. Shaving cuts the hair at the surface without removing the follicle or root, preserving the melanin target.
Stop Using Self-Tanner and Avoid Tanning
Tanned skin, whether from UV exposure or self-tanning products, contains excess melanin in the epidermis. When laser energy is delivered to tanned skin, it competes for absorption between the epidermal melanin and the follicular melanin, which reduces efficacy and increases the risk of burns, blistering, or hyperpigmentation. Stop self-tanning products at least 4 to 6 weeks before your appointment, and avoid deliberate UV tanning throughout your treatment course.
2 Weeks Before Your Appointment
Review Medications and Supplements with Your Provider
Certain medications and supplements increase photosensitivity and can cause unexpected skin reactions to laser energy. Review the following with your provider before your appointment:
- Antibiotics: doxycycline, tetracycline, fluoroquinolones, and other photosensitizing antibiotics should be discussed with your provider. Do not stop prescribed medications without consulting your prescribing physician; inform your laser provider of any antibiotic use
- Retinoids: topical and oral retinoids (tretinoin, Retin-A, isotretinoin/Accutane) increase skin sensitivity. Stop topical retinoids 2 weeks before treatment; oral isotretinoin typically requires a longer pause and must be discussed with your dermatologist and laser provider
- Blood thinners and NSAIDs: aspirin, ibuprofen, and fish oil increase bruising risk; discontinue if your health allows 5 to 7 days before treatment
- Hormonal medications: oral contraceptives and HRT can affect hair growth patterns; inform your provider but do not stop without medical consultation
Avoid Direct Sun Exposure
Begin protecting the treatment area from direct sun exposure 2 weeks before your appointment. Apply broad-spectrum SPF 30 or higher daily to any areas being treated that receive sun exposure. This gives any recent sun exposure time to fade and reduces the risk of treating recently tanned skin.
48 to 24 Hours Before Your Appointment
Shave the Treatment Area
Shave the entire treatment area 24 to 48 hours before your appointment. This is required, not optional. Shaving ensures the hair is present in the follicle for laser targeting while removing surface hair that could cause unwanted smoke or burning at the skin surface during treatment. Do not shave the day of your appointment; allow 24 hours between shaving and treatment to let any minor irritation subside.
Clean the Skin
The treatment area should be thoroughly clean, free of lotions, deodorant, makeup, sunscreen, perfumes, or any topical products. These can interfere with laser energy delivery or cause unexpected reactions when heated. Shower and cleanse the area before your appointment but do not apply any products afterward.
Avoid Alcohol
Avoid alcohol for 24 hours before your appointment. Alcohol can cause vasodilation, which affects skin temperature and may contribute to increased sensitivity during treatment.
Day of Your Appointment
- Arrive with completely clean, product-free skin on the treatment area
- Wear loose, comfortable clothing that provides easy access to the treatment area without rubbing or irritating it afterward
- Avoid applying any products to the treatment area before your appointment
- Do not apply numbing cream unless specifically instructed by your provider; the Motus AZ+ has built-in comfort features and your provider will advise on whether topical numbing is needed for your specific area
- Bring a list of your current medications and supplements
A common question: should you take pain medication before laser hair removal? For the Motus AZ+, most patients find the treatment comfortable enough that pre-medication is not necessary. If you have concerns about discomfort, discuss this with your provider before the appointment; they can advise on appropriate options for your treatment area and individual sensitivity.
What to Tell Your Provider Before Treatment
At your intake before each session, inform your provider of:
- Any new medications started since your last appointment, including antibiotics, hormonal medications, or supplements
- Any recent sun exposure or self-tanning product use on the treatment area
- Any changes in your skin in the treatment area, including rashes, burns, active breakouts, or skin infections
- Any recent procedures in the treatment area
- Any concerns about previous laser sessions, including areas that were more sensitive than expected

Frequently Asked Questions: Laser Hair Removal Preparation
What happens if you don't shave before laser hair removal?
If the surface hair is not shaved, the laser energy will be absorbed by the hair above the skin surface, causing burning and smoke at the surface rather than effective heating of the follicle. This reduces efficacy and can cause discomfort. Your provider may shave the area at the appointment if you forgot, but this adds time and may not be as thorough as preparation done the day before. Shaving is always required.
Can you use numbing cream before laser hair removal?
Numbing cream is sometimes used for sensitive treatment areas such as the bikini line, underarms, or face. At Institute for Ageless Living, the Motus AZ+ laser system is designed to be significantly more comfortable than many other laser platforms, making numbing cream unnecessary for most patients in most treatment areas. If you have significant sensitivity concerns, discuss this with your provider before your appointment and they will advise on whether topical numbing is appropriate for your session.
How long before laser hair removal should you stop waxing?
Stop waxing, plucking, and threading at least 4 to 6 weeks before your first session and throughout the entire treatment series between sessions. This ensures the hair follicle contains an intact hair shaft for the laser to target at each appointment. Shaving is the only acceptable form of hair removal during your laser treatment course.
Can you exercise before laser hair removal?
Avoid intense exercise on the day of your laser hair removal appointment. Exercise significantly elevates body temperature and skin temperature, which can affect how the laser interacts with your skin. Light activity earlier in the day is generally acceptable, but arrive for your appointment in a cooled-down state. After treatment, avoid intense exercise for 24 to 48 hours to reduce the risk of irritation in the treated area.
Does tanning affect laser hair removal results?
Yes, significantly. Tanned skin contains excess melanin in the epidermis that competes with follicular melanin for laser energy absorption. This reduces treatment efficacy and increases the risk of burns or post-inflammatory hyperpigmentation. The Motus AZ+ is designed to be safer for darker skin tones than many laser platforms, but all laser hair removal systems require avoiding recent tanning for optimal safety and results. Daily SPF use throughout your treatment course is strongly recommended.

Yes. Institute for Ageless Living in Longmont, CO offers laser hair removal using the Motus AZ+ laser system, which is effective for all skin tones including darker complexions. We serve patients throughout the greater Boulder County area.
