Why Do Results Vary from Person to Person?

Lifestyle habits directly influence the rate of collagen production and breakdown, so they have a considerable impact on treatment outcomes and maintenance. Even if a procedure "promotes" collagen regeneration, if daily factors rapidly break down collagen, the improvement effect may be offset.

UV exposure is a major factor that accelerates aging. When exposed to UV rays, enzymes (MMPs) that break down collagen are activated, reducing dermal collagen. Smoking has also been identified as a factor that lowers collagen synthesis and increases breakdown enzymes, accelerating skin aging. In studies of identical twins, the twin who smoked was observed to show more advanced skin aging. Lack of sleep is associated with inflammatory responses, while deep sleep is reported to promote skin recovery and collagen production.

Post-treatment care is one of the key factors that determine outcomes. Heat- and ultrasound-based lifting procedures do not produce results immediately after the session; instead, collagen regenerates over the following 2–3 months, with effects appearing gradually. The quality of care during this regeneration period influences the final result.

In particular, UV protection is a basic measure to protect regenerating collagen. If newly formed collagen is repeatedly exposed to UV rays, its breakdown is accelerated, potentially reducing the degree of improvement. Basic lifestyle management, such as moisturizing, smoking cessation, and adequate sleep, also helps create a favorable environment for regeneration.

Conversely, if care is neglected, even with the same procedure, the duration of results may be shorter or the improvement may feel less noticeable. In other words, the procedure is the starting point, and subsequent care contributes to the completeness and longevity of the outcome.

The gap between expectations and actual results usually arises when the "mechanism of action" of the procedure and the "expected change" do not align. Non-surgical lifting aims for gradual improvement in elasticity through collagen regeneration, which differs in principle from surgical excision, which produces immediate and dramatic changes.

Treatments such as Thermage® FLX and Ultherapy PRIME® are known to produce results not immediately after the procedure but gradually over 2–3 months as collagen regenerates. If one expects the skin to become tight the day after the procedure without knowing about this time lag, the actual progress may feel significantly different from expectations.

Additionally, due to individual differences in skin condition and lifestyle habits as explained earlier, applying someone else's degree of change directly to oneself can easily inflate expectations beyond reality. Understanding the mechanism of the procedure and one's own starting point is the first step in reducing this gap.

The most accurate way to set realistic expectations is to consider "your skin condition + the procedure's mechanism + your care plan" together during a consultation. Average online progress or others' cases are only reference materials and are difficult to use as a basis for predicting your own results.

First, it is advisable to determine the direction of expected improvement by considering your own skin thickness, elasticity, degree of sagging, and age range. Then, taking into account the timing of when the treatment effect appears (typically gradual changes over several months), the duration of results, and the number of sessions needed, you can adjust your expectations to be realistic. Combining a care plan that includes UV protection, smoking cessation, and adequate sleep can help with improvement and maintenance.

In clinical practice, it is not uncommon for satisfaction to vary due to expectations that are either too high or too low. Above all, individual variation is natural, and what matters is establishing a plan suited to your own skin. Accurate diagnosis and realistic goal setting are possible only after examining your skin condition directly, so we recommend consulting a specialist to determine the direction.
