Dr. Melaxin Peel Shot on the Body: Feet, Underarms, Knees

Yes, you can use Dr. Melaxin Peel Shot on the body, and the brand even makes a body-specific version: the Peel Shot Exfoliating TX-Spray, a rinse-off gel spray listed for the back, chest, shoulders, elbows, knees, underarms and buttocks. The face ampoules (White Rice and Black Rice) can also be used on small rough patches such as elbows, knees and heels, as long as you treat body skin with the same care you give your face.
This guide focuses only on body use: which format to pick for each zone, how often to apply it, and the three things that cause most body-peel problems in Canada and the USA (shaving, deodorant and sun). If you are new to the line itself, start with our complete Dr. Melaxin Peel Shot guide, then come back here.
Quick answer: For large or hard-to-reach areas (back, chest, underarms, buttocks, bumpy arms), use the TX-Spray once or twice a week on dry skin, massage gently and rinse in the shower. For small rough spots (elbows, knees, heels), a few pumps of the Black Rice or White Rice ampoule work well. Never apply on freshly shaved, waxed, broken or sunburned skin, moisturize afterwards and protect exposed areas from the sun.
Face ampoules vs the TX-Spray: which one for your body?
All Peel Shot products work on the gommage principle: you apply a gel to dry skin, massage it, and soft flakes roll up as the formula loosens dull surface cells before you rinse it away. The difference is in the packaging, the size and the extra actives.
| Product | Format and size | Body areas it suits | Notable ingredients |
|---|---|---|---|
| Peel Shot Exfoliating TX-Spray | Rinse-off gel spray, 200 ml (6.76 fl oz) | Back, chest, shoulders, underarms, buttocks, arms, elbows, knees | Tranexamic acid, niacinamide, glycolic acid, gluconolactone, capryloyl salicylic acid, vitamin C derivative, hyaluronic acid |
| Peel Shot Black Rice Ampoule | Rinse-off gel, 80 ml (2.7 oz) | Elbows, knees, heels, small rough patches | Rice bran water, charcoal powder, gluconolactone, small amount of salicylic acid |
| Peel Shot White Rice Ampoule | Rinse-off gel, 80 ml (2.7 oz) | Dry, dull patches on arms, knees, tops of feet | Fermented rice complex, niacinamide, ceramides, AHA and PHA |
| Peel Shot Kojic Acid Turmeric | Rinse-off gel, 80 ml (2.7 oz) | Mainly the face; small marked areas only | Kojic acid, turmeric, glycolic acid, gluconolactone |
Simple rule of thumb: an 80 ml face ampoule goes quickly if you spread it over your whole back or legs, so keep the ampoules for spot work and use the 200 ml spray for big surfaces. The spray also means you can reach the middle of your back without a brush. If you are deciding between the two face ampoules, our White Rice vs Black Rice comparison covers that choice in detail.
Step-by-step body routine in the shower
- Start dry. Gommage gels are meant for dry skin. Apply before you step under the water, or towel off a zone completely first.
- Apply a thin layer. Spray the TX-Spray from a short distance onto the area, or dispense one or two pumps of an ampoule for an elbow or knee.
- Massage softly for 20 to 40 seconds. Use your palm in small circles. The flakes appear on their own; scrubbing harder does not make the product work better and can irritate.
- Rinse well with lukewarm water. Hot showers dry out freshly exfoliated skin, which matters in a Canadian or northern US winter.
- Moisturize within a few minutes. A fragrance-free body lotion or cream helps the skin feel comfortable and keeps the smooth result longer.
Do not leave the gel on like a mask, and do not apply a second round on the same day if you did not see many flakes. The amount of flakes depends on the gel texture and is not a measure of how much dead skin was removed.
How to use Peel Shot zone by zone
Feet and heels
Use the Black Rice or White Rice ampoule on the tops of the feet, the sides and the heels, on dry skin before a shower or footbath. Massage, rinse, dry carefully between the toes and follow with a thick foot cream. A gommage gel softens the surface; it will not remove deep calluses or cracked heels on its own, so pair it with a rich cream every night. Avoid cracked, bleeding or infected skin. If you have diabetes, poor circulation or numbness in your feet, do not self-treat rough skin: ask your doctor, a pharmacist or a foot-care professional first.
Elbows and knees
These are the easiest areas to start with because the skin is thicker. One pump of an ampoule or a short spray of TX-Spray per elbow or knee is enough. Many people see smoother, less ashy-looking skin after a few sessions when they also moisturize daily.
Underarms
The TX-Spray lists underarms among its target areas, mainly for rough texture and the look of uneven tone. Underarm skin is thin, folded and often irritated by shaving and deodorant, so go slowly: once a week to start, on skin that has not been shaved or waxed recently, and only if the skin has no razor bumps, cuts or rash. Darkening under the arms can come from friction, shaving, hormones or certain medical conditions, so if it appears quickly, spreads, or comes with velvety thickening, see a doctor rather than relying on exfoliation.
Back, chest and shoulders
The spray format makes this zone practical. Spray, reach what you can with your hands, and rinse thoroughly so no gel stays in the folds of the skin. Body exfoliation can help the back feel smoother and help marks from old breakouts look less obvious over time. Painful, deep or cystic breakouts on the back or chest are a medical issue and deserve a visit to a family doctor or dermatologist.
Bumpy arms and thighs
Small rough bumps on the back of the upper arms or on the thighs (often keratosis pilaris) can look and feel smoother with regular gentle exfoliation plus daily moisturizing. They are a chronic, often genetic pattern, so expect improvement in feel and look, not a permanent fix. If the bumps are red, itchy or widespread, a dermatologist can suggest targeted options.
How often: a body frequency guide
| Area | Best format | Start with | Maximum if well tolerated |
|---|---|---|---|
| Elbows, knees | Ampoule or TX-Spray | 1 to 2 times a week | 3 times a week |
| Feet and heels | Black Rice or White Rice ampoule | 1 time a week | 2 to 3 times a week |
| Back, chest, shoulders | TX-Spray | 1 time a week | 2 times a week |
| Bumpy arms, thighs | TX-Spray | 1 time a week | 2 times a week |
| Underarms | TX-Spray | 1 time a week | 2 times a week, never after shaving |
These are conservative starting points based on the brand guidance (start once or twice a week and increase only if your skin stays comfortable). Space sessions at least two days apart, and skip a session whenever an area feels tight, stings or looks pink.
Shaving, waxing and laser: timing matters
Shaving and waxing already remove a layer of surface cells, so adding acids right away is the most common cause of stinging. The brand advises against using the TX-Spray and ampoules on freshly shaved or waxed skin.
- Exfoliate first, shave later: a Peel Shot session the day before shaving can help the razor glide and may reduce the look of ingrown hairs.
- After shaving, wait at least 24 hours, longer after waxing or if you see redness or bumps.
- After laser hair removal or any in-clinic treatment, follow your provider instructions and pause exfoliants until they say it is fine.
- Never use any Peel Shot on nicks, scratches or skin that is sunburned or peeling.
Deodorant, fragrance and other products
Freshly exfoliated underarm skin can sting under alcohol-based deodorants, scented sprays or antiperspirants. The easiest fix is to exfoliate in the evening shower and apply deodorant the next morning. If you must use deodorant after a session, pick a fragrance-free formula and apply it on fully dry skin.
On the rest of the body, avoid stacking other exfoliating products on the same day: AHA or urea body lotions, retinoid creams, scrubs or exfoliating gloves. Note that the TX-Spray contains fragrance, so if your skin reacts to perfume, patch test on the inner forearm for 24 to 48 hours before trying it on a larger area.
Sun protection for exfoliated body skin
The TX-Spray and the ampoules contain alpha hydroxy acids such as glycolic acid, and AHA products can make skin more sensitive to the sun. That matters most for shoulders, chest, arms and the tops of the feet in summer, from beach weekends to sandals season. Use a broad-spectrum sunscreen on any exposed area you exfoliate, reapply after swimming or sweating, and cover up during peak hours.
In the USA, sunscreens are regulated as over-the-counter drugs by the FDA; in Canada, Health Canada regulates them, so check for a DIN or NPN on Canadian labels. Readers in the UK and Australia have their own sunscreen rules, but the same daily-protection habit applies. For more on choosing a formula, see our Korean sunscreen guide.
Who should skip body peeling
- Anyone with eczema, psoriasis or active rashes on the area.
- People who are pregnant or breastfeeding, or using prescription topicals, until they have checked with a health professional.
- Anyone with broken, infected, sunburned or freshly treated skin.
- Children: keep the products out of reach.
In winter, when indoor heating dries body skin, many people do better with fewer sessions and richer creams; our Korean winter skincare routine has ideas for cold, dry months.
Frequently asked questions
Can I use the face Peel Shot ampoule on my body?
Yes, on small areas such as elbows, knees and heels. For large areas like the back or legs, the 200 ml TX-Spray is more practical and was designed for the body.
Is Dr. Melaxin Peel Shot good for underarms?
The TX-Spray lists underarms as a target area. Use it once a week on unshaved, unirritated skin and wait until the next day for deodorant.
Can I use the TX-Spray on my face?
No. The brand says not to spray toward the face. Use a face ampoule from the Peel Shot line instead.
Will Peel Shot remove calluses on my feet?
It can soften the surface, but thick calluses and deep cracks need regular rich foot cream and, if painful, a foot-care professional.
Why does my skin sting after a body session?
Usually because the skin was recently shaved, the product was rubbed too hard or used too often. Rinse, moisturize, pause for a week and restart less often. If stinging or redness persists, stop and ask a pharmacist.
Used on dry skin, with a gentle hand and enough time between sessions, the Peel Shot line can make rough body areas look and feel smoother. Choose the TX-Spray for big surfaces, an ampoule for small rough spots, and treat sun protection and shaving timing as part of the routine, not an afterthought.
