Isoi Pore Tightening Essence
Isoi's Pore Tightening Tonic Essence is a toner-essence hybrid built around one job: refining the look of visibly open pores while it hydrates. The line comes in two formulas, the original and a Bulgarian Rose version, and ships in sizes from a 50ml travel bottle up to a 260ml large-capacity pump for daily use. Pat it on after cleansing as the first hydrating step, before serum and moisturizer.

Buying guide
How to choose an Isoi Pore Tightening Essence
Isoi built this line around a single idea: tighten the look of pores without stripping the skin. It shows up on skinsli in ten variants across two formulas and four sizes, which makes picking the right bottle the main decision, not whether the product itself works for you.
What a pore-tightening tonic essence actually is
It sits between a toner and a light essence: watery enough to pat on with hands or a cotton pad, but formulated to leave a slightly tightened, smoothed finish rather than plain hydration. Use it as the first step after cleansing, before serum and moisturizer.
Original formula vs. Bulgarian Rose
Isoi sells this essence in two formulas. The original Pore Tightening Tonic Essence is the fragrance-light, straightforward version. The Bulgarian Rose Pore Tightening Tonic Essence is the same pore-focused formula built around Bulgarian rose water, with a softer floral scent for anyone who wants that layered into their routine.
Choosing a size
The line runs from a 50ml bottle sized for travel or a first try, through the everyday 130ml bottle, up to 250ml and 260ml large-capacity pumps for anyone using it twice a day long term. If you're new to the formula, start with 130ml before committing to a large-capacity size.
About the "Old" 130ml listing
You'll also see a 130ml listing marked "(Old)." That's a prior packaging run of the same original formula, kept in stock separately from the current 130ml bottle. Either one is the standard (non-rose) formula.
How to use it
Apply after cleansing, either pressed in with clean hands or swept on with a cotton pad. Follow with your serum and moisturizer as usual. It layers fine under sunscreen and makeup once it's absorbed.
Who it suits
Best fit for anyone dealing with visibly enlarged pores or a t-zone that feels loose by midday, especially combination and oily skin types. The Bulgarian Rose version is worth choosing if you also want a routine step that smells like something rather than nothing.
Pairing it in a routine
Because it's a first-step toner-essence, it pairs with almost anything that follows: a vitamin C or niacinamide serum for brightening, or a lightweight gel moisturizer if you're prone to oiliness. Skip layering it with another strong exfoliating toner on the same day.
Storage and shelf life
Keep the bottle capped and out of direct sun; like most watery Korean toners it's happiest at room temperature. Use the large-capacity 250-260ml sizes within about a year of opening so the formula stays fresh through daily use.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What does the Isoi Pore Tightening Essence actually do for pores?
It's a watery toner-essence that leaves skin feeling tighter and smoother right after application, which visually softens the look of enlarged pores. It won't shrink pore size permanently, but used consistently it keeps a t-zone from looking loose by midday.
What's the difference between the original and the Bulgarian Rose Pore Tightening Essence?
Both target pores with the same core formula. The Bulgarian Rose version is built around Bulgarian rose water and carries a soft floral scent; the original is fragrance-light. Pick rose if you want a scented step, original if you don't.
Which size of Isoi Pore Tightening Essence should I buy?
Start with the 130ml bottle for everyday use. The 50ml size suits travel or a first try before committing, and the 250ml/260ml large-capacity pumps make sense once you know you'll use it twice a day long term.
Is the "(Old)" 130ml listing a different formula from the current one?
No. The "(Old)" 130ml listing is a prior packaging run of the same original (non-rose) formula, sold separately from the current 130ml bottle while stock lasts.
When in my skincare routine do I use this essence?
Right after cleansing, as the first hydrating step. Pat or sweep it on with a cotton pad, let it absorb, then follow with your serum and moisturizer.
How should I store the Isoi Pore Tightening Essence once opened?
Keep the cap on tight and store it out of direct sunlight at room temperature. If you buy a 250ml or 260ml large-capacity size, aim to use it up within about a year of opening.
