For a San Carlos resident, laser hair removal is less a single appointment than a calendar commitment: most patients need a series of 4 to 8 treatments, so the real planning question is how a whole course fits your weeks and your commute. This page explains how a course is built, how it is prepared for and counted, and what repeat trips to our San Mateo office look like from San Carlos. Dr. Susan Lin, M.D. personally performs every treatment at MD Laser and Cosmetics, 448 N San Mateo Drive, about 7.6 miles from San Carlos; the laser hair removal page describes the treatment itself.
How a course of laser hair removal is structured
Laser energy is absorbed by the pigment in a hair and is aimed at the follicle that produces it. The catch is that hair does not grow all at once. At any moment some hairs are in an active growth phase, where treatment is most useful, and others are resting beneath the skin. A single session reaches only the hairs that are active that day, which is why treatment is delivered as a series rather than a one-time event.
The visits are spaced weeks apart, not days apart, so that hairs that were resting at one visit have had time to enter the growth phase before the next. Dr. Lin advises on the interval at your consultation, because spacing is part of planning the whole course. The aim of a course is a reduction in unwanted hair over time, not a one-day result.
Why the number of visits differs from person to person
The practice’s general range is 4 to 8 treatments. Where a patient lands within or around that range depends on age, hair density and genetics. Those three factors are why two people treating the same area can need different numbers of visits. We state the typical course here, but a web page cannot tell any individual how many visits she will need; that is worked out in person or by video with Dr. Lin.
It also means the right way to plan is in ranges. If you are budgeting time, think of a course as somewhere between four and eight appointments, spread across several months, rather than fixing on a single number on day one.
Preparing for each visit, and what happens afterward
- Avoid waxing for 2 to 3 weeks before a treatment.
- Shave the treatment area the day before your appointment.
- Expect no downtime. Laser hair removal does not require you to clear your schedule afterward, so a visit can sit alongside the rest of your day.
Because every visit in the series is with Dr. Lin, the same physician sees how the area responded last time and can adjust the plan as the course goes on. If you have questions about hair removal between visits, bring them to your appointment.
How areas are counted and what the consultation covers
Treatment is planned by area. Both underarms together count as a single area, which is useful to know when you are mapping out a course. How many areas your own plan involves is an individual matter that Dr. Lin assesses at the consultation.
The consultation is educational: Dr. Lin assesses the area or areas you are interested in, explains your options and reviews recommendations and pricing, so you can decide for yourself. Consultations are held in person or by video on Zoom, which can save one drive before you commit to a course. Same-day treatment after a consultation is possible, but check that your work and social plans allow for it before you book. Patients under 18 are seen only with their responsible parent present, which is worth building into a series for a teenager.
Planning repeat trips from San Carlos
Because a course means many visits, the distance counts more here than it would for a one-time treatment. The drive from San Carlos is about 7.6 miles, which is roughly 12 minutes without traffic. That figure is a free-flow estimate, not a rush-hour forecast, so check a maps app for the hour of your appointment. The modeled route runs from El Camino Real onto Holly Street, then US-101 north, off at E 3rd Avenue, and on to N San Mateo Drive via S Delaware Street and E Poplar Avenue. Northbound, that stretch of US-101 uses the San Mateo 101 Express Lanes. Counting both directions, a 4-visit course is roughly 61 miles of driving and an 8-visit course roughly 122 miles.
By Caltrain, San Carlos is a Local-only stop with 75 weekday trains. The ride to San Mateo takes 10 minutes with three intermediate stops, followed by a 0.80-mile walk of about 15 minutes from San Mateo station to our door. For repeat visits, driving is usually the simpler choice, and parking at the office is free and on site.
Our hours are Monday to Friday, 9:00 AM to 5:00 PM, by appointment only. Census estimates (ACS 2020-2024) show that 35.0% of San Carlos workers worked from home, which may make a weekday slot easier to arrange. Either way, a series means a weekday slot each time, so it helps to look ahead at your calendar before the first treatment. To get started, book a consultation or contact the office. Our San Carlos med spa page gives an overview of the practice for San Carlos patients, and the areas we serve page lists the other communities we see.
Questions from San Carlos Patients About a Laser Hair Removal Series
How many trips to San Mateo should I plan for a course of laser hair removal?
Most patients need 4 to 8 treatments, depending on age, hair density and genetics, so plan for somewhere in that range of appointments, plus the consultation unless it is done by video or the same day. From San Carlos each trip is about 7.6 miles each way. Dr. Lin sets the number and spacing for your own plan at the consultation.
Can I get to my appointments from San Carlos by Caltrain?
Yes, though driving is simpler for many patients. San Carlos is a Local-only Caltrain stop with 75 weekday trains, and the ride to San Mateo takes 10 minutes with three intermediate stops. From San Mateo station, it is a 0.80-mile walk of about 15 minutes to our office. Check the current timetable and our weekday hours before you plan the trip.
What should I do before each laser hair removal appointment?
Avoid waxing for 2 to 3 weeks before your treatment, and shave the area the day before. If anything about your own situation is unclear, ask Dr. Lin at the consultation or by phone at (650) 340-7546 so you start the course with the right preparation.
Will I need time off after each visit?
No. Laser hair removal has no downtime, so you can plan a visit around your normal day. If you have a consultation first and want treatment the same day, that is possible, but make sure your schedule allows for it. Over a multi-visit series, the main thing to plan around is the trip itself rather than recovery.
Do both underarms count as one area?
Yes. Both underarms together count as a single area. How many areas your own plan involves, and how they are combined in a course, is something Dr. Lin assesses at the consultation, where she also reviews pricing. Consultations are available in person or by video, so you can ask about areas before making the trip from San Carlos.
