When performing 3 sessions at intervals of 2-4 weeks, you can expect an effect of sebum secretion suppression for about 6 months to 1 year.

Since it primarily targets sebaceous glands, acne bacteria, and inflamed areas with minimal impact on normal skin tissue, it can be applied relatively safely to sensitive skin or skin that has become irritated due to repeated troubles.

You may experience slight redness after the procedure, but it will subside within 3 days, so there's no need to worry.

Depending on the current condition of blackheads, whiteheads, and inflammatory acne, extraction can be performed together if necessary. Extraction cleans out sebum and comedones already accumulated inside pores, while Gold PTT aims to manage the sebaceous glands and skin environment prone to acne. Therefore, depending on your skin condition, extraction to clear current lesions and PTT for sebaceous gland management can be planned together.

Both PTT and PDT use light energy, but their mechanisms of action differ. PTT (Photothermal Therapy) uses a photothermal reaction where gold nanoparticles absorb laser energy and generate heat, managing sebaceous glands and the area around hair follicles. PDT (Photodynamic Therapy) involves applying a photosensitizer to the skin and then irradiating it with specific wavelengths of light to trigger a photochemical reaction. Therefore, there are differences in the substances and energy used, the way they act, and the skin reaction and recovery process after the procedure.

Gold PTT is less about eliminating all acne immediately after the procedure, and more about observing a reduction in sebum secretion and the occurrence of new acne over time. Depending on your skin condition, some may notice changes in oiliness or sebum amount after one or two sessions, and with repeated treatments, you can see a change in the frequency and severity of inflammatory acne. The timing and extent of noticeable changes vary from person to person.

Gold PTT is generally considered an acne treatment with relatively low pain burden. During laser irradiation, you might feel a momentary prickling or warm sensation, but it is often performed without separate anesthesia. However, in areas with severe inflammation or on sensitive skin, you might feel heat or prickling more intensely, and the degree of pain varies individually.

The primary goal of Gold PTT is to manage active acne and excessive sebum secretion. While it can help prevent new scars from forming as acne subsides, its main purpose is not to directly improve existing deep acne scars. If indented scars such as ice pick, boxcar, or rolling scars remain, separate treatments tailored to the scar type, such as Potenza or fractional laser, can be considered after stabilizing active acne.

Gold PTT is a treatment method that can be utilized for cases with excessive sebum secretion and recurrent inflammatory acne, such as red papules or pustules. It induces a selective thermal reaction around the sebaceous glands and hair follicles, managing both sebum secretion and inflammatory lesions. If the acne is severe or involves nodular/cystic acne, medication or other treatments may be considered in conjunction with PTT, rather than PTT alone.

Gold PTT utilizes the principle of delivering gold particles to the vicinity of sebaceous glands, then generating thermal energy with a laser to induce selective thermal damage to the sebaceous glands and reduce their activity. Therefore, it can help reduce sebum secretion and improve the skin environment prone to acne. However, it is not a procedure that completely eliminates all sebaceous glands, and the required extent and skin response vary from person to person.

Gold PTT can be utilized with the aim of reducing excessive sebum secretion, one of the main causes of acne. When gold particles are delivered around the sebaceous glands and absorb laser energy, a selective thermal reaction occurs, which can help reduce sebaceous gland activity. It can be particularly considered in cases of high sebum production and recurrent inflammatory acne. However, sebum secretion is influenced by various factors such as hormones, seasons, and lifestyle, so individual responses may vary.
