The combination of retinol 2.5%, Vitamin C, and Vitamin A works together with a collagen-supporting formula to promote skin firmness and radiance with regular use.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this serum suitable for sensitive skin?\u003c\/h4\u003e\n\u003cp\u003eA: This serum is formulated for unisex, whole-face use and is designed for a wide range of skin types. However, as retinol can be potent, we recommend starting with a patch test and introducing it gradually into your routine — especially if you have sensitive skin. Always follow up with a broad-spectrum SPF during daytime use.\u003c\/p\u003e\n\u003ch4\u003eQ: How long before I see visible results from using this facial serum?\u003c\/h4\u003e\n\u003cp\u003eA: Visible improvements in skin brightness and tone can vary from person to person. Most users begin to notice a more radiant and even complexion within 4–8 weeks of consistent daily use. For best results, use regularly as part of a complete skincare routine.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this serum with my existing moisturiser or sunscreen?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This lightweight serum is designed to layer seamlessly under your moisturiser. If applying during the day, always finish with a broad-spectrum sunscreen, as Vitamin C and retinol can increase skin sensitivity to UV exposure.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does the Retinol 2.5% Vitamin C Facial Serum do for my skin?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This facial serum is formulated to visibly brighten the complexion, reduce the appearance of dark spots and uneven skin tone, and support a smoother, more youthful-looking surface.
