IPL vs Shaving: Which Saves More Time Long-Term?

March 27, 2026

Shaving takes 5-10 minutes. IPL sessions take 20-30 minutes. So shaving is faster, right?

Not when you do the actual math. Let's calculate the real time investment for both methods over weeks, months, years, and a lifetime.

The Daily Math: Shaving Time Adds Up Fast

Watch: IPL Hair Removal in Action

Most people who shave regularly do it every 1-2 days. Let's be conservative and calculate for every other day.

Shaving time breakdown:

Actual shaving: 5-10 minutes (legs, underarms, bikini area)
Shower prep: Already doing this, so we won't count it
Post-shave care: 2-3 minutes (moisturizing, treating nicks)
Total per session: 7-13 minutes

Frequency:

Every other day = 3.5 times per week
15 times per month
180 times per year

Annual time investment:

Low estimate: 180 sessions × 7 minutes = 1,260 minutes = 21 hours per year
High estimate: 180 sessions × 13 minutes = 2,340 minutes = 39 hours per year

That's roughly one full day to almost two full days every year spent shaving.

The IPL Investment: Initial Time vs Long-Term

IPL requires significant time upfront, then decreases dramatically.

Initial phase (Weeks 1-12):

Treatment frequency: Once weekly
Session length: 20-30 minutes (full body)
Total sessions: 12

Time investment for initial phase:

12 sessions × 25 minutes average = 300 minutes = 5 hours total

Maintenance phase (After month 4):

Treatment frequency: Once every 4-8 weeks
Session length: 10-20 minutes (touch-ups on remaining hair)
Annual sessions: 6-12

Annual maintenance time:

9 sessions × 15 minutes average = 135 minutes = 2.25 hours per year

The Skintekie IPL approach delivers 70-90% hair reduction, meaning you're only maintaining a fraction of what you previously shaved.

The 1-Year Comparison

Year 1 with shaving:

Time spent: 21-39 hours
Hair removal never ends
Same time investment next year

Year 1 with IPL:

Initial treatments: 5 hours
Partial year maintenance: 1-2 hours
Total: 6-7 hours

IPL actually saves time starting in the very first year—and the gap only widens from there.

The 5-Year Comparison

5 years of shaving:

105-195 hours total
That's 4.4 to 8.1 full days
Still shaving just as often in year 5

5 years with IPL:

Initial treatments: 5 hours
4 years maintenance: 9 hours
Total: 14 hours

Over 5 years, you save 91-181 hours by choosing IPL over shaving. That's literally weeks of your life back.

The Lifetime Calculation

Let's assume you start hair removal at age 16 and continue until age 70 (54 years total).

Lifetime shaving:

54 years × 21 hours minimum = 1,134 hours
54 years × 39 hours maximum = 2,106 hours
That's 47 to 88 full days of your life spent shaving

Lifetime with IPL:

Initial treatment: 5 hours
53 years maintenance: 119 hours
Total: 124 hours = 5.2 days

The difference? You save 42 to 83 days of your life by using IPL instead of shaving.

But What About "Quick Touch-Up" Shaving?

Some people argue: "But I'll still need to occasionally shave even with IPL for those few stray hairs."

True. Let's account for that.

With IPL + occasional touch-up shaving:

IPL reduces hair by 70-90%
Touch-up shaving needed every 2-3 weeks instead of every 2 days
Time per touch-up: 2-3 minutes (much less hair)
Annual touch-ups: 17-26 times
Annual shaving time with IPL: 51-78 minutes = 0.85-1.3 hours

Combined annual time with IPL:

IPL maintenance: 2.25 hours
Touch-up shaving: 1 hour
Total: 3.25 hours

Still dramatically less than 21-39 hours of pure shaving.

The Hidden Time Costs of Shaving

We haven't even counted these time sinks:

Shopping for razors and supplies: 30-60 minutes per year

Dealing with razor burn/ingrown hairs: Variable, but treating irritation takes time

Mental load: Planning when to shave, remembering to do it, stress about stubble

Wardrobe restrictions: Choosing clothes based on whether you've shaved

These aren't huge individually, but they compound over time.

The Real IPL Time Investment

Let's be completely honest about what IPL requires:

Initial learning curve: First 2-3 sessions take longer as you learn proper technique

Device setup: Charging, positioning, finding good lighting

Skin preparation: Shaving before IPL (though you're doing this anyway with regular shaving)

Post-treatment care: Applying SPF, avoiding sun exposure

Even accounting for these factors, IPL saves massive time long-term compared to endless shaving.

When Shaving Makes More Time Sense

There are scenarios where shaving remains the faster choice:

Very infrequent hair removal: If you only remove hair a few times per year, shaving is faster

Unsuitable for IPL: Dark skin or light hair that IPL can't effectively treat

Short-term use: If you only need 1-2 months of hair removal

Specific events only: Shaving for occasional special occasions vs year-round hair removal

For most people dealing with regular, ongoing hair removal, IPL wins the time game.

Combining Methods Strategically

Many IPL users adopt a hybrid approach:

Use Skintekie IPL for large areas (legs, arms)
Quick shave for any remaining fine hair or last-minute touch-ups
Best of both worlds: major time savings with flexibility

Understanding how different hair removal methods work helps you choose the right combination.

The Bottom Line: Time Math is Clear

Shaving feels faster because each individual session is quick. But you're locked into that cycle forever, accumulating thousands of hours over a lifetime.

IPL requires more time upfront (5 hours over 3 months), but then drops to minimal maintenance (2-3 hours per year). Over just 5 years, you save 90-180 hours. Over a lifetime, you reclaim 40-80 full days.

The Skintekie IPL device is a time investment that pays dividends for decades—giving you back literally weeks of your life that would otherwise be spent in endless shaving cycles.

If time is valuable to you (and it should be), the math isn't even close. IPL wins.
