To use the bt-sculpt GEN2, cleanse your skin, apply a generous layer of conductive medium such as Restyfluid, then glide the probes slowly along each area of the face in the directions shown in the manual, keeping both probes in contact. Finish with a hydrating toner or serum. Short, regular sessions are what help the look of toned, refreshed skin build over time.
Key takeaways
- Start with clean, oil-free skin: a water-based gel cleanser works best before microcurrent.
- Use plenty of conductive medium and reapply it as soon as it starts to feel tacky.
- Work one area at a time, moving slowly and keeping both probes flat against the skin.
- The GEN2 gives you audio feedback linked to skin contact, which helps you keep your technique consistent.
- Short sessions most days at first, then a few times a week, is the pattern most people follow.
What is the bt-sculpt GEN2?
The bt-sculpt GEN2 Microcurrent Facial Sculpting System is a handheld, rechargeable microcurrent device from Bio-Therapeutic, a brand with more than 50 years of microcurrent expertise. It is designed to temporarily tone and tighten the look of skin.
Compared with the original, it is more compact and has a recalibrated probe angle. Its patented, self-tensioning K4iTEK probe system works across four independently controlled energy pathways, and it uses Suzuki Sequencing from the same technology family as Bio-Therapeutic’s professional devices. It was named Best Microcurrent Device in the NewBeauty Awards 2026.

What do you need before your first session?
- A fully charged device. Charge it as described in the instructions before first use.
- A water-based cleanser. Gel Cleanse removes oil and residue without leaving a film.
- A conductive medium. Restyfluid, with low molecular weight sodium hyaluronate and peptides, works as a conductive medium as well as a toner.
- A finishing mist or serum. Aquafuse Hyaluronic Repair is a hydrating toner mist with ceramides and hyaluronic acid that pairs well with microcurrent.
- A mirror and good light, so you can see where the probes are.
Before you start, read the safety section of the manual and our checklist below. The question of why the gel matters is covered fully in why microcurrent needs a conductive gel.
How do you use the bt-sculpt GEN2, step by step?
The routine below is a general framework. Your device’s manual is the final word on settings, timings and movements.
Step 1: Cleanse and dry
Wash with a gentle, water-based cleanser and pat dry. If you wear makeup or SPF, make sure it is fully removed: residue can stop the current flowing evenly. Using a cleansing brush first is fine; our sonic cleansing brush guide explains how to fit one in.
Step 2: Apply conductive medium to one area
Smooth a generous layer onto one section, for example the left side of the jaw. It should sit on the surface rather than sink in completely. Working section by section stops it drying before you get there.
Step 3: Switch on and position the probes
Turn the device on and select your setting as shown in the instructions. Place both probes flat on the skin. The GEN2 gives an audible signal linked to skin contact, so listen for it and adjust your angle or add more gel if contact is lost.
Step 4: Glide and hold
Move slowly along the area, usually upwards and outwards, pausing where the manual tells you to. Do not drag or press hard: gentle, steady contact matters more than pressure.
Step 5: Work around the face
Repeat on each section, reapplying conductive medium as you go.
- Jawline, from chin towards the ear
- Cheeks, from the mouth towards the temple
- Around the mouth and nose-to-mouth area
- Forehead, upwards from the brows
- Brows, along and slightly upwards towards the temple
- Then repeat on the other side
Step 6: Finish and hydrate
Wipe away any leftover gel or press it in if it is a serum-type medium, then mist with a hydrating toner and follow with your usual serum and moisturiser. In the morning, finish with SPF.
How often should you use the bt-sculpt GEN2?
A common approach is a short session most days for the first four to six weeks, then two or three times a week to maintain the look. Some people like a quick session in the morning before a busy day; others prefer it in the evening as part of a wind-down. Follow the frequency in your manual.
| Goal | How often | Tip |
|---|---|---|
| Building a routine | Most days, short sessions | Same time each day makes it a habit |
| Maintaining the look | Two to three times a week | Keep the sequence the same each time |
| Before an event | The day before and on the day | Pair with a cooling gel masque |

What are the most common mistakes with the bt-sculpt GEN2?
- Too little gel. This is the most common cause of a prickly feeling and patchy results.
- Moving too fast. Slow, deliberate passes work better than quick strokes.
- Pressing too hard. Pressure does not increase the effect; contact does.
- Using over oily products. Facial oils and rich balms can interfere with conductivity, so save them for afterwards.
- Inconsistency. Occasional use rarely gives the look people are hoping for.
Who should check before using it?
Speak to your GP or doctor before using any microcurrent device if you are pregnant, have a pacemaker or other implanted electronic device, have epilepsy, have or are being treated for cancer, or have recently had facial surgery, fillers or injectables. Avoid broken, inflamed or sunburnt skin. Our microcurrent safety checklist explains each of these in more detail.

Frequently asked questions
Why does the bt-sculpt GEN2 tingle or prickle?
A faint tingle can be normal, but a sharp prickle usually means the conductive medium has dried or the probes have lost full contact with the skin. Stop, add a fresh layer of gel to the area and place both probes flat before continuing. Moving more slowly and avoiding pressure also helps keep the sensation comfortable throughout the session.
Can I use the bt-sculpt GEN2 around my eyes?
Follow the movements shown in your manual and keep the probes on the brow bone and the outer eye area rather than on the eyelids or directly under the lower lashes. Skin around the eyes is thin and delicate, so use a generous layer of conductive medium and a light touch, and stop if anything feels uncomfortable.
Should I use the bt-sculpt GEN2 in the morning or at night?
Either works. Many people like the morning because skin looks fresher for the day ahead, and it fits neatly before moisturiser and SPF. Others prefer the evening for a calmer, unhurried routine. The best time is the one you will stick to, because regular use is what helps the look of toned skin build.
Can I use aloe vera gel instead of a conductive gel?
Some people do, but plain aloe gels can dry quickly and vary in how well they conduct, which can make sessions less comfortable. A water-based formula designed to work with microcurrent, such as Restyfluid, keeps the skin slippery for longer and adds hydration. Avoid oils, balms and silicone-heavy products as your conductive layer.
