Recurring Milia and Pustular Acne: How Gold PTT and Agnes Laser Can Help

Many people struggle with recurring milia (comedonal acne) or pustular acne that flares up with every seasonal change and hormonal shift. Especially during the transition from summer to autumn, changes in sebum secretion, stress, and hormonal imbalance combine to worsen acne for many.

Causes of Milia and Pustular Acne

Milia (comedonal acne) are small raised bumps formed when sebum and dead skin cells accumulate inside pores. Pustular acne is a more severe form where bacterial infection adds inflammation and pus to these blockages. Key causes include hormonal changes (around menstruation, stress), poor skincare habits, excessive sebum secretion, and clogged pores.

What is Gold PTT?

Gold PTT applies nano-gold particles to the skin, then uses a laser (Synergy MPX) to irradiate them. The nano-gold absorbs and converts the light into heat, selectively destroying sebaceous glands. Unlike conventional laser treatments, it suppresses sebaceous gland function without directly damaging the skin surface. It is especially effective for patients with recurring acne, as it regulates sebum production itself to address the root cause of acne.

What is Agnes RF Laser?

Agnes uses ultra-fine insulated microneedles to deliver radiofrequency energy directly to sebaceous glands. Energy is delivered precisely inside the pore to destroy sebaceous glands and treat acne. Notably, Agnes is effective not only for recurring pustular acne but also for sebaceous hyperplasia (enlarged sebaceous glands appearing as small yellow bumps on the nose and cheeks). Because Agnes targets only the precise treatment area with minimal surface damage, it offers a shorter recovery time.

Differences Between Gold PTT and Agnes RF

Gold PTT excels at broadly suppressing sebaceous glands across a larger area, while Agnes RF excels at precisely targeting individual acne lesions or sebaceous hyperplasia. Depending on the patient's acne type and severity, combining both or selecting the most suitable option is key.

Improving Acne Scars and Pigmentation — Synergy Focus Therapy

After acne heals, residual scarring (pitted scars, uneven texture) and pigmentation (redness, brown marks) require separate treatment. Synergy Focus Therapy combines two or more lasers or energy modalities to simultaneously address acne scars and pigmentation. It promotes skin regeneration and corrects pigmentation to help create smoother, more even post-acne skin.

Treating acne isn't just about eliminating existing breakouts — it requires a comprehensive approach that includes sebaceous gland management to prevent recurrence, plus improvement of existing scars and pigmentation. A thorough consultation with a dermatologist is recommended to find the right treatment plan.
