Lefton Effects and Treatment Information: A Complete Guide from Principle to Recovery

When skin elasticity doesn't feel like it used to, many people become curious about non-invasive lifting treatments that don't use heat. Lefton is one of the treatments frequently mentioned for this need, described as a non-thermal method that uses low-intensity shockwaves to physically stimulate the environment beneath the skin.

This article covers, in order, how Lefton works, the changes you can expect, the treatment process and downtime, and home care after the procedure.

What Is Lefton? Understanding How It Works

Unlike radiofrequency (RF)-based lifting treatments that primarily use heat as their energy source, Lefton is described as a non-thermal device that delivers low-intensity shockwaves to the skin layers. It is known to work by physically stimulating tissue that has become hardened or fibrotic during the aging process, loosening it, and inducing a collagen response within the dermis.

Drawing on principles common across energy-based skin treatments in general, delivering energy in short pulses is explained as triggering tissue responses through photoacoustic or physical impact effects, and this stimulation is reported to potentially lead to collagen remodeling and production responses within the dermis. However, this is a general explanation applicable to this category of treatments overall, and results can vary depending on individual skin condition and degree of response.

The scope of application and energy intensity can vary depending on the area and purpose, so it is necessary to confirm the actual method of application through consultation.

Changes You Can Expect from Lefton

Lefton aims to help with the following changes. However, it should be noted that the degree of effect and perceived results vary significantly by individual.

In terms of elasticity, it aims to improve skin firmness; in terms of tightening, it targets a sense of skin becoming firmer. For texture refinement, it aims toward smoother skin texture, and for inducing a collagen response, it is described as targeting collagen production and remodeling responses within the dermis.

Some effects may appear right after the treatment, but results usually emerge gradually over about 1 to 3 months, and duration is reported to be roughly 6 to 12 months, which also varies by individual.

The Lefton Treatment Process

The treatment begins with a consultation and skin condition assessment, followed by cleansing and application of a topical anesthetic cream. Energy is then applied to each area according to the device's settings, followed by soothing care and aftercare guidance. It is often described that patients can return to daily activities without a separate recovery period.

Treatment time varies by area but typically takes about 20 to 30 minutes. Pain is known to be mild, though this also varies by individual.

Lefton vs. Thermage vs. Oligio: What's the Difference?

Lefton uses low-intensity shockwaves and is described as involving relatively less thermal damage and pain, while Thermage uses monopolar radiofrequency (RF) and is known for uniformly treating large areas. Oligio, meanwhile, is known to combine monopolar RF with a surface cooling system.

All three treatments share the common feature of stimulating the dermis to induce a collagen response, but their energy delivery methods and primary target depths differ, so the suitable treatment can vary depending on individual skin condition and concerns. Rather than concluding that one treatment is superior, it is advisable to consult with a specialist to choose the method best suited to you.

Downtime and Home Care After Treatment

Lefton uses a topical anesthetic cream and involves almost no separate recovery period, so it is known that returning to daily activities on the same day is often possible. However, temporary redness or sensitivity may remain at the treatment site, so care that minimizes irritation right after the treatment can be helpful.

After energy-based treatments, the skin barrier may become temporarily sensitive, so care focused on soothing and hydration can help support the recovery process. Starting on the day of treatment, using low-irritation soothing care to stabilize the skin, followed by a gradual approach that replenishes deep hydration during the recovery period, is commonly recommended.

Home Care Makes the Difference in Post-Treatment Recovery

Right after treatment, soothing care to calm sensitized skin can help, and in the following days, deep-hydration care to replenish moisture that may have been lost can support the recovery process. ABJU cream is formulated around this two-step recovery concept: STEP1 Ultra Cera-Rich focuses on soothing redness and barrier care immediately after treatment, while STEP2 Hydro Re-Boosting aims to provide deep hydration during the recovery period. However, the cream does not replace or guarantee the treatment's effects, and following the guidance of your treating medical provider should take priority for the treatment's course and management.
