Can pores be closed permanently?

No. They can be visibly refined — and that holds only with continuous care.

Does a dermaroller help with enlarged pores?

Indirectly. Short needles (0.25 mm) improve absorption of what you apply afterwards but do not refine pores themselves. On congested skin, bio microneedling with dissolving spicules is the safer choice.

How long until pores look finer?

Sebaceous pores look calmer after two to three weeks; slackened pores need eight weeks or more because collagen has to be rebuilt first.

Is GHK-Cu too rich for oily skin?

No. The serum is water-based and oil-free, so it neither sits on the skin nor blocks pores.

Skin concern

Refining enlarged pores

Pores are not doors — they do not close. They look smaller when the skin around them regains tension.

Why pores look large

Lost collagen lets the pore wall slacken, so the channel appears wider. Oxidised sebum widens the opening optically on top of that.

Three pore types — only two respond to skincare

Sebaceous pores on the nose and inner cheek: respond to cleansing and sebum control, usually calmer within two weeks.
Slackened, teardrop-shaped pores on the cheek and jawline: a collagen issue, where GHK-Cu works over weeks.
Scarred pores after acne: these need dermatological procedures; a serum only refines the rim.

Dermaroller for pores: what it can and cannot do

A home dermaroller at 0.25–0.5 mm works in the stratum corneum and mainly improves how well actives absorb afterwards. Deep collagen remodelling only happens at needle lengths that belong in professional hands. On oily, breakout-prone skin, rolling can spread bacteria and make pores look temporarily larger.

Bio microneedling with spicules is the controlled version: the microstructures dissolve in the skin, so there is no reused needle, no disinfection question and no downtime. GHK-Cu then penetrates deeper without the barrier being injured.

An eight-week protocol

Weeks 1–2: two to three drops in the evening on slightly damp skin, konjac sponge once a week.
Weeks 3–4: oiliness and redness recede, the pore rim looks more defined.
Weeks 5–8: the collagen work shows — pores on cheek and jawline appear shallower.
After that: maintenance. Stop, and the starting point returns over months.

The three most common mistakes

Over-cleansing: a damaged barrier produces more sebum, not less.
Daily astringent toners: a short-term effect and long-term irritation.
Switching products every fortnight: collagen remodelling needs the same routine for months.

All of it in one formula

EDNF25070922 combines GHK-Cu, bio microneedling, the 5-peptide complex and 24K gold in a single serum.
