# Pore Device Use Log: What to Record and When to Take a Break

> There isn't enough research to say what pore devices do, so write down the intensity you used and how long redness lasted each day, and skip the device on days your skin shows warning signs.

A log for weeks you use a pore device: date, intensity level, how long redness takes to fade and when you cleaned the head, plus clear signs to rest the device.

| Item | Detail | Basis |
|---|---|---|
| At-home device studies that measured pores | Our evidence contains no study that directly measured pore size with an at-home device | Editorial evidence review |
| Example of use frequency | An at-home LED study had people use the device twice a day for 2.5 minutes each time for 4 weeks and followed them to 12 weeks (acne lesions were the target) | 2013 PMID 23278295 · A |
| Changes you can't see | In the skin of 25 healthy volunteers washed 3 times a day for 4 days with an automated cleansing device, nothing changed to the eye or on a color meter, but water loss (TEWL) rose with all of the workplace (occupational) skin cleansers tested (not a facial cleanser study) | 2014 PMID 24588368 · B |
| Heat function | 42°C heat for 30 seconds increased ingredient penetration only from a lotion, with no difference from a gel | 2014 PMID 24445121 · A |
| Friction | The Korean Dermatological Association lists friction and mechanical irritation as factors that can trigger or worsen acne | Korean Dermatological Association · Institution |

## What should you record in a week you use a pore device?

Five things are enough: the date, the function and intensity level, how long you used it, how long redness took to fade, and the day you cleaned the head. Since there isn't enough research to judge what these devices do, keeping track of which days were hardest on your own skin gives you something to go on when you set next week's use.

There is a reason to log redness time on its own. In a 2014 trial of repeated washing with workplace (occupational) skin cleansers, the skin of 25 people looked no different to the eye or on a color meter, yet water-loss readings rose with every cleanser tested (this was not a facial cleanser study). That means repeated mechanical stress can add up even when skin looks fine on the surface, so comparing a week of daily use after work with a week of every-other-day use can bring out the difference.

*Comparing your cheek on device days and rest days in the same light shows which days were harder on your skin.*

## Do at-home skincare devices really help products absorb better?

No study has measured absorption directly with an at-home pore device, so you can't say for sure that absorption improves. Even in related human experiments, the results depended on the conditions. In a 2014 trial that applied 42°C heat for 30 seconds, allantoin penetration rose only from a lotion, and a gel with the same ingredient showed no difference.

In a 2008 experiment that exposed 12 healthy men to water-filtered infrared-A, penetration of a water-soluble dye rose, but an oil-soluble dye showed no difference, and water-loss readings and skin surface temperature (32.8°C to 36.4°C) went up as well. That experiment used special medical equipment on the forearm, so it doesn't carry over to at-home face devices. On days you use a heat function, write the names of the products you applied that day in your log, so you can trace back the combination if stinging shows up.

## Do at-home microneedling, LDM or radiofrequency devices work as well as a dermatologist?

Our evidence has no study comparing at-home devices with in-office procedures under the same conditions. There are studies of home LED devices, but all of them looked at acne lesions, not pore measurements.

In a 2013 trial in 35 Korean people with acne, inflammatory lesions in the group using a blue and red LED device decreased by 77% from baseline at week 12, while the sham-device group showed no clear change. In a 2011 split-face comparison of 30 people, lesion size and redness also settled faster on the blue light side. However, a 2023 meta-analysis of 31 studies pointed out that devices, wavelengths and doses varied from study to study, and results from a device with one wavelength can't be extended to other devices. Methods that make tiny punctures in the skin, like microneedling, and radiofrequency are something to discuss with a medical provider.

*Home devices differ in type and settings from study to study, so don't stretch one device's results to another.*

## How should you clean cushion puffs, sponges and brushes, and how often should you replace them?

The American Academy of Dermatology (AAD) advises washing makeup brushes every week and not sharing them with others. Its reason is that bacteria and oil can be passed along, so it's sensible to apply the same rule to puffs, sponges and device heads that touch your skin directly.

No study has set a replacement schedule, so the cleaning-day column in your log becomes your guide. Mark days when you reused something before it had dried completely and days when the head's surface was cracked, then watch whether breakouts cluster afterward. If you share a device with family or a roommate, give each person their own head.

## When should you give the device a day off?

Rest it on any day when redness or stinging from the previous day's use is still there the next morning. Since the Korean Dermatological Association names friction and mechanical irritation as factors that can make acne worse, there's no reason to add mechanical stress on a day your skin is already sensitive.

It also helps to set other no-device days: days you used an exfoliating product or peel, the week you start a new skincare product, days you spent a long time in the sun, and weeks when breakouts tend to flare, such as before your period. That makes causes easier to separate. On rest days, wash gently with just your fingers and write "rest" and the reason in your log.

*On rest days, wash with your fingers only and note in your log why you skipped the device.*

## 7-day pore device log

| Day | Function used or rest | Level and time | Until redness faded | Head or puff cleaning | Anything else that day |
|---|---|---|---|---|---|
| Mon | Vibrating brush | Level 1, 1 min | Within 10 min | Washed and dried after use | None |
| Tue | Rest | — | — | — | No redness from the day before; every-other-day rule |
| Wed | Heat | Level 1, 3 min | 20 min | — | First day of a new lotion → keep them apart next time |
| Thu | Rest | — | — | — | Stinging lasted until morning |
| Fri | Rest | — | — | — | Exfoliated that day |
| Sat | Vibrating brush | Level 1, 1 min | Within 10 min | Weekly cleaning | None |
| Sun | Review | — | Count days over 30 min | Check head condition | Set next week's frequency |

The entries above are an example. If redness lasted more than 30 minutes on two or more days in a week, use the device less often or lower the intensity next week.

## When should you have skin changes from a device checked?

- If blisters or scabs form where you used the device, or redness or swelling lasts several days, stop using it and see a dermatologist.
- If tiny bumps or pus-filled breakouts increased after you started using the device, have a dermatologist check.
- For care that uses energy or needles on the skin, such as microneedling, radiofrequency or lasers, talk to a dermatologist.

## Evidence summary for this guide

- In a 2013 double-blind trial in 35 Korean people with acne (PMID 23278295), inflammatory lesions in the at-home blue and red LED device group decreased by 77% and non-inflammatory lesions by 54% from baseline at week 12 (no significant change in the sham-device group); pores were not measured.
- In a 2014 trial in which the skin of 25 healthy volunteers was washed 3 times a day for 4 days with an automated cleansing device (PMID 24588368), nothing changed to the eye, but water loss rose with all of the workplace (occupational) skin cleansers (not a facial cleanser study).
- In a 2014 human trial that applied 42°C heat for 30 seconds (PMID 24445121), ingredient penetration rose only from a lotion, with no difference from a gel.

## Frequently asked questions

### Do at-home skincare devices really help products absorb better?

The evidence behind this guide includes no study that measured absorption with an at-home pore device. In a related human experiment, applying 42°C heat for 30 seconds increased allantoin penetration only from a lotion, with no difference from a gel. It is hard to say a single device changes absorption, and results depend on the formula and conditions.

### Do at-home microneedling, LDM or radiofrequency devices work as well as a dermatologist?

We found no study in our evidence that compared at-home devices with in-office procedures under the same conditions. For home LED devices, there are only small trials comparing acne lesions against sham devices, and none measured pores. If you are considering methods that make tiny punctures in the skin, like microneedling, or radiofrequency procedures, talk to a dermatologist.

### How should you clean cushion puffs, sponges and brushes, and how often should you replace them?

The American Academy of Dermatology (AAD) advises washing makeup brushes every week and not sharing them, since bacteria and oil can be passed along. Following the same rule, washing puffs, sponges and device heads once a week and letting them dry completely is a reasonable approach. No study has set a replacement schedule, so replace a head when it cracks or keeps a smell.
