Hi Girls Bye Pores 10% Niacinamide Pore Serum 30 ml

• 10% niacinamide: the amide form of vitamin B3; focuses on the look of pores, sebum and tone.
• 0.5% zinc PCA: supports a more balanced look of sebum.
• Dendriclear™: the formula's patented third key ingredient.
• Supporting ingredients: Lubrajel Marine, panthenol, 8D hyaluronic acid, allantoin.
• 30 ml. The formula was updated in March 2026; it focuses on the look of pores for combination, normal and oily skin.

Combination, normal and oily skin; for those whose priority is visible pores and the look of shine during the day. Dry skin is not listed on its label; if you use it on dry skin, apply it once a day, followed by moisturiser. Sensitive skin: use less often and patch test first; start with once a day.

1. Cleanse your face; if you use a toner, apply it first.
2. Spread 3–4 drops over the whole face, starting with areas where pores are more visible, such as the T-zone and the sides of the nose; do not apply around the eyes.
3. Allow it to absorb, then apply your moisturiser.
4. When using it in the morning, finish with sunscreen; make-up comes last.

Can be used 1–2 times a day. Sensitive skin should start with once a day and add a second application as the skin feels comfortable.

In the same evening routine as Slyc-Alright: toner first, then Hi Girls Bye Pores. As the toner contains no niacinamide, the two products do not duplicate each other's work. For the final hydrating step, the water-based, silicone-free Any Time Of Day; as this cream also contains niacinamide, use the serum less often if redness occurs.

• Pore size is largely structural; the serum does not make pores smaller but helps them look less visible.
• It does not exfoliate and does not stop oiliness completely.
• The high niacinamide concentration can cause temporary redness on sensitive skin; use it less often, and pause use if irritation persists.
• In case of contact with eyes, rinse thoroughly with water. Do not apply to irritated skin.
• If you are pregnant or breastfeeding, or have a skin condition, consult your doctor before use.

Does it make pores smaller? No; pore size is largely structural. Hi Girls Bye Pores helps pores look less visible.

How many times a day is it used? It can be used 1–2 times a day, in the morning and evening serum step. Dry skin is not listed on its label; if it is used on dry skin, apply it once a day, followed by moisturiser. On sensitive skin, start with once a day and add a second application as the skin feels comfortable.

Can it cause redness? On sensitive skin, it can: the 10% niacinamide in the formula may cause temporary redness. If this happens, use it less often and pause use if irritation persists; if you also use Any Time Of Day, which contains niacinamide, in the same routine, use the serum less often.
