It works on the skin's surface to encourage cell renewal, smooth texture, reduce the appearance of pores, and deliver excellent hydration, making it suitable even for sensitive skin types.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the TRSTAY Lactobionic Acid Essence suitable for sensitive skin?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! PHAs like lactobionic acid are known for their gentle, well-tolerated nature, making this essence a great option for those who find stronger exfoliating acids too harsh. However, as with any new skincare product, we recommend a patch test before full application.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this face serum both morning and night?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The essence is suitable for both AM and PM routines. If using in the morning, always follow up with a broad-spectrum SPF to protect your freshly brightened skin.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long before I see results from using this pore-refining essence?\u003c\/h4\u003e\n\u003cp\u003eA: Most users begin to notice improvements in skin texture, hydration, and radiance within 2–4 weeks of consistent daily use. Pore appearance and overall tone tend to improve progressively over time.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is lactobionic acid and how does it benefit my skin?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Lactobionic acid is a polyhydroxy acid (PHA) — a gentler cousin of AHAs like glycolic acid.
