When sebum erupts in summer, blackhead management becomes even more important.
Hello, this is Yonsei Bombit Dermatology.
As temperatures and humidity rise in summer,
pores open more easily and sebum production increases sharply.
As a result, blackheads begin to stand out around the nose, forehead, and chin.
�
Blackheads are not simply sebum,
but oxidized “oxidized sebum masses” that have reacted with oxygen in the air.
Trying to squeeze them out recklessly or relying only on patches
can instead enlarge pores and even cause inflammation.

Today, during the summer period when sebum surges,
we’ll tell you about scientific and effective blackhead care methods.

Causes and Care of Blackheads
1️⃣ Why do blackheads get worse in summer?
✔ Increased sebaceous gland activity
Sebum production increases every time the temperature rises by 1 degree.
In summer, sebaceous glands are generally more active.
✔ Pores become clogged as sweat and sebum mix together
Salts and waste left behind as sweat evaporates
combine with sebum to clog pores and cause blackheads.
✔ Thickening of dead skin cells due to UV rays
When the skin thickens its dead skin cells to protect itself,
sebum has a harder time escaping, making blackheads worse.
2️⃣ How should blackheads be managed?
📌 The most important key is: 'Do not squeeze them forcefully'
Forcibly squeezing them damages the tissue around the pores and can cause inflammatory acne or enlarged pores.
✔ Change your cleansing habits
-
Avoid excessive cleansing (twice a day is enough)
-
Use lukewarm water + a gentle cleanser
-
For areas where blackheads are concentrated, leave the foam on for a longer time.
✔ Exfoliate only '1–2 times a week'
-
Use exfoliants containing AHA, BHA, or PHA
-
Avoid physical scrubs as much as possible
✔ Combine soothing and pore-tightening care
-
After cleansing, use a toner with soothing ingredients (allantoin, panthenol)
-
Do not rub; gently pat to help it absorb.
3️⃣ How are blackheads managed at a dermatology clinic?
At Yonsei Bombit Dermatology, blackheads are not simply removed
but approached with a step-by-step program tailored to the skin condition.
✔ Jessner peel
: Uses AHA to remove old dead skin cells around the pore opening,
and BHA, which has high penetration power, to remove deep sebum inside the pores,
improving the pore environment so sebum does not build up.
✔ Soothing care after extraction
: After safe extraction at the dermatology clinic,
inflammation and irritation are minimized with anti-inflammatory and soothing laser treatment.
✔ Alex Toning
: If pigmentation or redness around the pores is present,
it can also improve the skin tone around blackheads.
✔ Aquapeel
: A popular summer procedure that cleans pores while removing sebum with a strong stream of water,
aiding in reducing blackhead recurrence.
✨ In closing
Blackheads are not a sign of “dirt,”
but rather the result of an imbalance in the skin environment.
Rather than squeezing them yourself or using irritating methods,
scientifically controlling sebum production and dead skin cell turnover,
and combining that with professional soothing care,
is the way to protect both pores and overall skin health.
At Yonsei Bombit Dermatology, safe and precise blackhead care
helps keep even your pores clean.
