What are blackheads really?
A blackhead is a clogged pore, but not from dirt. What forms it is a mixture of sebum (the natural oil produced by the skin) and dead cells that accumulate at the opening of the hair follicle. When this mixture is exposed to the air, it oxidises and turns black. Hence its name: open comedone.
Unlike a whitehead, which remains closed under the skin, a blackhead is in contact with the outside. That explains its characteristic colour and also why it is easier to see, but not necessarily easier to remove.
Why do they concentrate in the T-zone?
The forehead, nose and chin (known as the T-zone) have a significantly higher density of sebaceous glands than the rest of the face. More glands means more sebum production, and more sebum means a higher likelihood of pores becoming clogged.
The nose is especially prone because its pores are anatomically larger and are continuously exposed to rubbing, pollution and temperature changes. All of this favours the accumulation of residue and makes blackheads on the nose more visible and persistent than in other areas.
Blackheads on nose: what makes them so difficult to remove
The size of the pore on the nose is not just aesthetic: it is functional. Larger pores accumulate more sebum and more dead cells, and being in an area with a lot of muscle movement and constant exposure, they become clogged more quickly.
In addition, many people make the mistake of trying to remove blackheads forcibly (by squeezing, using adhesive strips or unsterilised tools), which irritates the skin, dilates the pore and ends up producing more sebum as a defensive response. The result is the opposite of what you want.
Factors that contribute to their appearance
Blackheads are not caused by dirt, but there are habits and factors that accelerate their formation:
| Factor | Why it matters |
| Excess sebum | Clogs the pore more quickly |
| Irregular keratinisation | Dead cells are not removed properly and clog the follicle |
| Hormonal changes | Androgens increase sebum production |
| Comedogenic products | They clog the pore from the outside |
| Incomplete make-up removal | Leaves residues that mix with sebum |
| Chronic stress | Raises cortisol, which stimulates the sebaceous glands |
Understanding what causes it in your specific case is what makes the difference between a treatment that works and one that does not.
Daily routine to remove blackheads without damaging the skin
The goal is not to remove all sebum (it is necessary for the skin barrier) but to regulate its production and keep pores clean. An effective routine is structured in three stages:
Morning and night: balancing cleansing
A cleansing foam or gel with a physiological pH (4.5–5.5) removes excess sebum without damaging the skin barrier.
Try the foam for oily skin, purifying mousse.
Cleansing twice a day is enough; doing it more often triggers the rebound effect: the skin produces more oil to compensate for what is taken away.
Twice a week: exfoliation with AHA/BHA
Alpha-hydroxy acids (AHA) renew the surface of the skin. Beta-hydroxy acids (BHA), especially salicylic acid, are lipid-soluble: they penetrate the pore, dissolve accumulated sebum and unclog from the inside. The combination of both twice a week is one of the best-documented strategies for reducing comedone formation on a sustained basis.
blemiderm resurfacing gel works with this combination in the evening routine.
Spot treatment
For emerging blemishes or areas with a higher concentration of blackheads, a spot treatment with drying and sebum-regulating active ingredients acts more directly without affecting the rest of the skin.
blemiderm local control is formulated for this specific use.
Blackhead removal: what is safe and what you should avoid
Manual extraction without prior preparation is the most common cause of inflammation, marks and dilated pores. If you do it, do it properly:
- What works: Gentle steam to open the pore, extraction with a clean, sterilised spatula or extractor, always on clean skin and with gentle lateral pressure, never inwards.
- What to avoid: Squeezing with your nails, using adhesive strips frequently (they dilate the pore in the long term), manipulating inflamed blackheads or those with surrounding redness.
The safest and most effective option continues to be professional extraction within a complete treatment protocol, where the skin is prepared and the process is carried out under controlled conditions.
