How to Prep Your Butt for Swimsuit Season: A 4-Week Countdown

Updated September 2026

To prep your butt for swimsuit season in four weeks, exfoliate gently two or three times a week, moisturize every day, handle hair removal a few days before the big day, and don't try anything new in the final week. Four weeks is enough for skin to feel noticeably softer and look smoother. It isn't enough to fade old dark marks, and nothing topical removes cellulite.

What can you realistically change in 4 weeks?

With four weeks of consistency, most people can:

• Make skin feel softer and smoother
• Cut down on rough, flaky patches
• Get skin looking more polished and moisturized
• See fewer new bumps from friction and shaving, thanks to better habits

You can't, in 4 weeks:

• Fade old dark marks. The AAD says lighter spots usually take 6 to 12 months.
• Get rid of cellulite. It's structural, and Cleveland Clinic notes 80% to 90% of women who've gone through puberty have cellulite.
• Make stretch marks disappear.

If your starting point feels rough, you'll likely notice a real difference by week 4. That's a good outcome.

What's the 4-week butt prep plan?

Week 1: Build the routine

Goal: Set the routine and let skin adjust.

• Daily: Gentle body wash. If you're breakout-prone, use a benzoyl peroxide or 2% salicylic acid wash and leave it on for a couple of minutes before rinsing.
• Twice this week: A small scoop of Becky Booty Scrub in the shower. Damp skin, light circles for 30–60 seconds, rinse.
• Daily after showering: Moisturizer on damp skin.
• Habits: Breathable underwear. Change out of sweaty workout clothes quickly. No picking.

Week 1 result: Skin starts feeling softer. No dramatic visual change yet, and that's normal.

Week 2: Add a daily lotion with a job

Goal: Smoother texture and a more even look.

• Keep the week 1 rhythm going
• Add daily: a niacinamide lotion or a lactic acid lotion. Pick one. Niacinamide if your skin is sensitive or prone to dark marks; lactic acid if you have rough, bumpy texture.
• If you shave or wax, exfoliate a day or two before, then wait 24–48 hours after before exfoliating again. More in razor bumps on the butt.

Week 2 result: Texture feels smoother.

Week 3: Stay consistent

Goal: Smooth, comfortable skin.

• Exfoliate up to 3 times this week, if your skin is handling it well. Back off if it's red or stinging; the AAD's at-home exfoliation guide warns that over-exfoliating causes redness and irritation.
• Keep up the daily lotion
• Optional: a light body oil (jojoba or squalane) over lotion at night if your skin is dry.

Week 3 result: Softer, smoother-looking skin.

Week 4: Maintain and polish

Goal: Keep what you've built. Show up comfortable.

• Two or three exfoliating sessions. Nothing new this week.
• Daily lotion and moisturizer
• 3 days before: Final exfoliating session. Moisturize generously.
• 2 days before: Shave or wax, if you do. Soften hair with warm water first and shave in the direction it grows, per the AAD's razor bump prevention tips.
• Day before: No exfoliating. Just moisturizer, or a body oil on damp skin after showering.
• Day of: Light moisturizer and water-resistant, broad-spectrum sunscreen on anything the suit doesn't cover.

Week 4 result: Soft, smooth, swimsuit-ready skin.

What else can you do? (optional)

Self-tanner

Self-tanner goes on more evenly over smooth skin. The AAD's self-tanner guide says to exfoliate first, make sure skin is completely dry, apply in sections, and wash your hands after each section. Do it after your final exfoliation and hair removal, a day or two before the event, so you have time to fix streaks. A self-tan doesn't protect you from the sun, so you still need sunscreen.

Glute work

Hip thrusts and glute bridges a few times a week build strength. Four weeks is a start, not a transformation, and it isn't skincare, but it feels good.

Lighting and posture

Soft light and a relaxed stance flatter everybody in photos. Don't overthink it.

What should you avoid in the final week?

• Don't try a new product. If it causes a reaction, skin won't have time to calm down.
• Don't get a chemical peel right before the event. Peeling skin can flake.
• Don't wax the day before. Give skin a couple of days to settle.
• Don't use a tanning bed. UV damage, burns and dark marks, none of which you want.
• Don't skip moisturizer. Dry skin looks dull.

What should you pack?

• Your usual moisturizer, travel-sized
• Broad-spectrum, water-resistant SPF 30+
• Breathable underwear for the flight or drive
• A change of clothes so you're not sitting in a wet swimsuit
• An attitude that says "the work is done; now I just enjoy it"

FAQ

I have 2 weeks, not 4. Is it still worth it?

Yes. Gentle exfoliation two or three times a week plus daily moisturizer for 14 days will make skin feel softer and smoother. It won't change tone much.

What if it's a wedding, not a beach trip?

Same routine. If dark marks are on your mind, start much earlier, since fading takes months.

Can I exfoliate the day of the event?

Skip it. Give skin at least a day after exfoliating so it isn't red or sensitive when you want it to look its best.

Will this work for my partner?

Yes. The routine works for every body. Butt skincare is gender-neutral.

I have one stubborn dark spot that won't fade in 4 weeks. What now?

Don't sweat one spot. Most people have something. Dark marks take months, so keep going after the trip. See why is my butt darker? for the longer game.

The bottom line

Four weeks of gentle exfoliation, daily moisturizer, smart hair-removal timing and nothing new at the end gets most butts to soft, smooth and swimsuit-ready. For the everyday version, see the butt skincare routine or how to make your butt soft. Set a reminder, do the work, show up.
