Hello,
This is Forena Clinic. 😊
"Is this just a whitehead?
Or will it turn into a pustular acne lesion?"
When you develop a skin breakout,
do you squeeze it recklessly with your fingers
or keep applying the same ointment?
The causes and treatment methods
differ depending on the type of acne.
Today, we will briefly explain the essentials:
how to accurately identify your type of acne
and the effective care and treatment methods
suited to each type. ✨
Acne you casually dismissed
that eventually left a scar
At first, it was just one small whitehead,
so you thought, “It’ll go away soon…”
and ignored it.
But have you ever had it become red and swollen
a few days later, even developing pus?
The more you touch it, the worse it gets,
and eventually the acne leaves a scar.
Why do some acne lesions disappear quickly,
while others gradually become worse?
Acne lesions that look the same
are not necessarily the same type.
What is acne?
Acne is a common skin condition
that develops when sebum and dead skin cells clog the pores.
Acne is broadly classified
into three types.

-
Whitehead acne
-
Pustular acne
-
Nodular and cystic acne
Although they may look similar on the surface,
the causes and treatment methods differ for each type of acne.
Accurately identifying your type of acne
is the first step in treatment.
- Whitehead Acne (Comedonal Acne)

Whitehead acne (comedonal acne)
is an early form of acne caused by sebum and dead skin cells
building up inside the pores.
It is often neither red nor painful,
but if left untreated, it may progress
to pustular acne.
☑️ Causes
Excessive sebum production
Dead skin cells that clog the pores Aerobic exercise
Hormonal changes
The effects of cosmetics or lifestyle habits
☑️ Treatment methods
Extraction treatment
Aqua peel · scaling
Sebum and dead skin cell care
Topical medication, if needed
- Pustular Acne

Pustular acne occurs when inflammation develops
because of sebum and bacteria inside the pores,
causing pus to build up.
It is often accompanied by redness, swelling, and pain.
Squeezing it with your hands or leaving it untreated
may lead to hyperpigmentation and scarring.
☑️ Causes
Excessive sebum production
Bacterial growth inside the pores
Inflammatory response
Stress · hormonal changes
☑️ Treatment methods
Anti-inflammatory injections
Professional extraction
Antibiotic treatment (if needed)
Acne treatment suited to the condition of your skin
- Nodular and Cystic Acne

Nodular and cystic acne is a severe form of acne
in which inflammation develops deep within the skin.
The lesions feel firm to the touch and are often very painful,
and they frequently persist for a long time.
If left untreated, they are highly likely to lead to deep scarring.
☑️ Causes
Excessive sebum production
Inflammation deep within the skin
Hormonal changes
Genetic factors
☑️ Treatment methods

Prescription oral medication
