E-Acne – Medical Acne Treatment with a Dermatologist

Most acne relapses happen not because the in-clinic protocol is ineffective, but because of the care gap between sessions. A science-based routine is a set of topical actives prescribed individually by the doctor — based on skin condition, age, living environment, occupation and real budget. At Eternal, the routine is not a generic product list but an extension of the protocol, and it often determines 30–50% of the final outcome. No skin can rely on the doctor's hands forever — correct at-home care is what keeps results sustainable.

Extraction is the mechanical step that releases micro-comedones, whiteheads, blackheads and dried cores from the follicle — something topicals alone often take weeks to push out. The common fears are pain, dark marks or spreading the acne. At Eternal, technicians are trained to a medical protocol, instruments are sterile, and the skin is cleansed and disinfected first. Only eligible cores are treated — inflamed, swollen pimples are never squeezed, as that is the main cause of atrophic scars and post-acne hyperpigmentation.

Biological light is one of the non-invasive, US FDA-recognised acne methods. Blue-light wavelengths act selectively on C. acnes bacteria — the main driver of inflammatory acne — while helping regulate sebaceous glands and reduce post-acne redness. No needles, no peeling, no downtime. It is a good choice for inflamed skin that cannot yet take stronger intervention, or for anyone who needs a gentle method interspersed within the protocol.

Peeling is often misunderstood as heavy flaking. In reality, a peel uses actives to dissolve the stratum corneum so comedones rise and gather, while also calming inflammation, regulating sebum and refining pores. Peels come in three depths — superficial, medium and deep — and most acne protocols only need superficial to medium. At Eternal, the doctor selects the agent, concentration, contact time and number of repeats based on how each skin responds. At the right concentration and the right time a peel is safe; getting either wrong is the real risk. See the Acne Peel treatment for oily, acne-prone skin.

CryO at Eternal uses the Cryo D-Cool device, combining three functions: heat, cold and electroporation iontophoresis. Low-intensity electrical pulses create temporary micro-channels on the skin surface, helping anti-inflammatory, sebum-reducing and antibacterial actives penetrate far deeper than ordinary topical application. The sensation is mostly a pleasant cool — no needles, no surface damage — making it suitable for those who want to boost the effect of actives without invasive intervention.

E-Acne is a technique that delivers actives into the dermis through micro-point tips — where the inflammation actually sits. Ordinary topicals struggle to cross the stratum corneum and break down at the surface, so their effect is limited. The E-Acne blend typically includes salicylic acid, retinol, peptides, zinc, hyaluronic acid and a vitamin complex — combined for anti-inflammatory, antibacterial and antioxidant goals. The micro-points are tiny, the feeling is only a light prickle, and there is no long downtime. It is a good option when inflammatory acne is not well controlled by topicals alone.

DPL is a high-intensity light technology US FDA-approved for mild to moderate acne, especially active pustular and inflammatory acne. Its main mechanism: reducing sebaceous gland activity and inflammation alongside stimulating collagen — which helps limit later post-acne scarring. A common worry with light devices is darkening caused by an unsuitable spectrum. Eternal uses the DPL Cellec V system with 9 light filters, emitting only the right pulse for each indication to limit side effects on Vietnamese skin.

The long-pulsed 1064nm laser is a medication-free route for acne — suitable for those who do not want, or cannot use, prolonged oral antibiotics or isotretinoin. The 1064nm wavelength reaches deep into the dermis, heating and shrinking the sebaceous glands, reducing excess oil and killing C. acnes, while stimulating collagen to ease inflammation and limit scarring. Eternal uses the Discovery Pico laser by Quanta System (Italy) — US FDA-certified, with two wavelengths and three pulse modes in one device, letting the doctor tune the parameters to each skin condition.
