It works as a gentle exfoliant to remove dead skin cells, helping to visibly refine pores and brighten skin tone. Unlike stronger acids, it also has humectant properties, meaning it attracts and retains moisture in the skin — making it ideal for even sensitive skin types.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the TRSTAY Pore-Refining Essence suitable for all skin types?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This essence is formulated for unisex use and is suitable for all skin types, including combination, oily, dry, and normal skin. Its gentle PHA formula makes it a good choice for those who want effective exfoliation without harsh irritation.\u003c\/p\u003e\n\u003ch4\u003eQ: How long does it take to see results from this brightening serum?\u003c\/h4\u003e\n\u003cp\u003eA: Most users begin to notice a more even skin tone and smoother texture within 2–4 weeks of consistent daily use. For best results, apply both morning and evening as part of your regular skincare routine and always follow with SPF during daytime use.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this serum with other skincare products?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. This essence layers well under moisturizers, SPF, and other serums. If you are introducing any new acid into your routine, we recommend starting slowly — every other day — and monitoring how your skin responds before using it daily.\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 the skin?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Lactobionic acid is a polyhydroxy acid (PHA) derived from lactose.
