Pore Minimizing 21 Serum 40ml

A high-potency serum that targets enlarged, sagging, and pigmented pores all at once

Pore concerns show up differently for everyone. Horizontal pores widened by excess sebum, vertical pores stretched by loss of elasticity, and melanin pores darkened by pigmentation. TIAM Pore Minimizing 21 Serum is a high-potency formula designed to address all three types of pore concerns at once. With 20% niacinamide and 1% zinc PCA, it regulates excess oil production and helps restore firmness to stretched pores.

Key ingredients and synergistic benefits

The combination of niacinamide and zinc PCA is known to enhance blemish care efficacy. Willow bark extract, a natural BHA, gently dissolves dead skin cells and impurities inside pores to refine skin texture. Allantoin helps brighten pores dulled by pigmentation.

• Niacinamide 20%: Minimizes pore size, controls sebum, evens skin tone
• Zinc PCA 1%: Reduces sebum, soothes skin
• Willow bark extract (natural BHA): Exfoliates, refines texture
• Allantoin: Brightens pores, calms skin

For all skin types concerned with shine

Though the texture feels concentrated and viscous, it absorbs completely and finishes fresh without any residue. After toning, dispense an appropriate amount and smooth gently over skin. Because this formula contains a high concentration of niacinamide, first-time users are encouraged to start with a small amount, monitor skin response, and adjust usage accordingly. If using in the morning, follow with sunscreen.

After toner, before essence or cream

Serums are applied right after toning, once your skin texture is prepped. With 20% niacinamide and 1% zinc PCA in a highly concentrated formula, this is more of a targeted treatment than a hydrating essence. After the serum absorbs, follow with your cream or moisturizer to lock everything in.

Suitable for morning and evening use

If sebum control and pore care are your main concerns, feel free to use this twice daily. When applying in the morning, always follow with sunscreen, as niacinamide can increase sun sensitivity. In the evening, cleanse thoroughly to remove the day's buildup first — this helps the serum absorb more effectively.

Dispense a small amount and spread thinly

This is a concentrated formula with some viscosity, so using too much at once can slow absorption. Dispense 1–2 pumps onto your palm, dot onto both cheeks, forehead, nose, and chin, then gently blend outward from the center of your face. For areas where pores are more visible, like the T-zone, you can apply a second light layer.

Routine pairings by pore concern

• Excess sebum and enlarged pores: Use after a lightweight hydrating toner, then seal with an oil-free moisture gel
• Loss of elasticity and elongated pores: Pair with a collagen or peptide cream for a tightening boost
• Hyperpigmentation and pigmented pores: Alternate with a vitamin C serum at different times of day to amplify brightening results

Precautions when using high-concentration niacinamide

This formula contains 20% niacinamide, which is on the higher end. If you're new to this ingredient, patch-test a small amount on your inner arm first and adjust usage accordingly. Sensitive skin may experience temporary redness, so we recommend starting with every-other-day application and monitoring your skin's response. Store in a cool place away from direct sunlight, and discontinue use if irritation occurs — consult a dermatologist if needed.
