If you have sensitive skin, we recommend patch-testing first and starting with less frequent use to allow your skin to adjust to the 20% glycolic acid concentration.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How often should I use a 20% glycolic acid face essence?\u003c\/h4\u003e\n\u003cp\u003eA: For most users, starting 2–3 times per week and gradually increasing frequency as the skin adjusts is a common approach. Always follow with a broad-spectrum SPF during daytime use, as glycolic acid (an AHA) can increase the skin's sensitivity to UV light.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this glycolic acid essence with other active skincare ingredients?\u003c\/h4\u003e\n\u003cp\u003eA: It's generally best to avoid layering multiple high-strength actives (such as retinols or other acids) at the same time. Incorporating the TRSTAY Glycolic Acid Essence into your routine on alternate evenings and following with a good moisturiser is a popular approach. Consult a dermatologist if you have specific skincare concerns.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What skin types is the TRSTAY 20% Glycolic Acid Essence suitable for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This brightening essence is formulated for unisex, whole-face use and is generally suitable for most skin types looking to improve radiance and skin texture.
