Pore Tightening Ampoule — Reddit Reviews
by Rejuran
Updated September 16, 2026
PDRN and acids combo targets texture and pores; hydration boost but harsh on tretinoin.
What the community says
This ampoule combines PDRN with exfoliating acids for pore refinement and texture smoothing. Reddit users find it hydrating yet caution it may cause irritation, especially on tretinoin nights. Studies found niacinamide, a related ingredient, can help acne and redness but layering acids risks sensitivity.
