Pore-tightening products have long relied on the tingle. Traditional astringents, alcohol-based witch hazel and menthol-heavy toners give an immediate tight, cool feeling that many people read as proof of effect, while quietly drying the skin. Rejuran's Pore Tightening Gel Mask takes a gentler route. It uses a cold hydrogel sheet, niacinamide high in the list and witch hazel water, the distilled, alcohol-free form, and it adds only mild exfoliants. It is fragrance-free and contains no essential oils. The result is a mask that makes pores look tighter for the day without stripping the skin.
Rejuran, the consumer skincare line of PharmaResearch, maker of the Rejuran PDRN injectables, launched the gel mask in 2025 as part of its Pore Tightening line, which also includes a toner pad, ampoule and cleansing balm. It comes in boxes of five 32g hydrogel masks, marked 'PDRx 3% with c-PDRN'.
The formula is thoughtfully assembled. After water, dipropylene glycol, glycerin and propanediol come cetyl ethylhexanoate, a light emollient, and niacinamide, sixth on the list. Niacinamide is the most important active here, with good evidence for regulating oil, improving barrier function and, with regular use, refining the look of enlarged pores. Witch hazel water follows, adding a light toning effect without alcohol. Aloe leaf juice, oat kernel, calendula, cucumber, apple, chestnut shell and persimmon leaf extracts contribute a soothing and antioxidant layer.
The hydrogel itself is built from carrageenan (Chondrus crispus), carob gum, agar, gellan gum and cellulose gum, which together form a thick, bouncy sheet that holds the essence against the skin and feels cold, particularly if chilled. That coolness is part of the effect: cold temporarily constricts surface blood vessels and makes pores look tighter.
Unusually for Rejuran's masks, the c-PDRN appears relatively high, as hydrolysed DNA thirteenth on the list, straight after soluble collagen. Polynucleotides have strong evidence when injected, but topical evidence is limited, so it is best seen as a supporting element. Gluconolactone and capryloyl salicylic acid, a gentle PHA and a slow-acting salicylic derivative, appear later and add a mild exfoliating touch without stinging. Panthenol, allantoin and adenosine round out the list.
In use, the mask is pleasant, particularly on warm days. The gel is thick and cold, clings well to the nose and cheeks and does not drip. After twenty to thirty minutes, it peels off to reveal skin that looks smoother, fresher and less shiny, with pores that appear slightly tighter. Patting in the residue leaves a soft, natural finish that works well under makeup.
The key caveat is that most of the pore effect is temporary. Cooling, hydration and a smoother surface make pores look smaller for several hours, but pore size is largely genetic and influenced by oil production and age-related loss of firmness. Lasting improvement in the look of pores depends on consistent leave-on actives such as niacinamide, salicylic acid or retinoids, alongside sunscreen. The mask works well as a complement to those, not a replacement.
The formula is gentle enough for most skin. It is fragrance-free and alcohol-free, and its exfoliants are mild and low in the list. Sensitive skin will usually tolerate it, though calendula, a compositae plant, is present for anyone with that allergy. The shea butter and ethylhexyl olivate mean it is not a strict fungal-acne-safe option, even though the formula is largely water-based.
Price is the main drawback. At twenty-nine dollars for five masks on Rejuran's store, each sheet costs close to six dollars, which is high even for hydrogel masks. The formula is better than many, and the cooling hydrogel format is genuinely pleasant, but the pore benefit is short-lived, which makes it more of an occasional treat than a routine staple.
Skin-type fit favours oily and combination skin, which will get the most visible effect on shine and pores. Normal skin will enjoy the cooling hydration. Dry skin can use it but will want a richer moisturiser afterwards, since the essence is light. Sensitive skin can generally use it, with a patch test for the calendula.
It is also worth comparing it within Rejuran's own range. The Skin Protection Mask is lighter and more refreshing but contains alcohol and fragrance, while the Moisture Treatment Mask is more soothing and barrier-focused. The Pore Tightening Gel Mask sits between them: cooling and targeted at oil and pores, yet gentle and fragrance-free.
A practical tip improves the experience considerably. Storing the pouches in the refrigerator for an hour or two before use makes the hydrogel firmer and colder, which enhances the temporary tightening effect and makes the mask easier to handle. It also feels particularly refreshing on puffy morning skin or after exercise.
In a routine, use it once or twice a week, morning or evening, after cleansing and toning. Leave it on for twenty to thirty minutes, remove it, pat the essence in, and follow with a light gel moisturiser. It pairs well with a daily niacinamide serum or leave-on BHA for longer-term pore care, and it makes a good pre-event treatment for smoother-looking skin under makeup.
The overall assessment is positive with a value caveat. The Rejuran Pore Tightening Gel Mask is a well-formulated, cooling, fragrance-free hydrogel that makes oily and combination skin look smoother and pores tighter for the day. Its effects are temporary, and its price is high for what it delivers, but as an occasional treatment it is one of the more thoughtful pore masks available.
