How to Use for Optimal Results For optimal results, apply a thin layer along the upper lash line and through the brows using the precision applicator. This must be done twice daily on clean, completely dry skin. Allow two minutes for the serum to dry before applying any other products. Visible improvements are typically seen within 4 to 6 weeks of consistent use. For the full transformation, daily application over at least 8 weeks is recommended. Safety Information & Storage A patch test is advised prior to first use, and contact with eyes should be avoided. Store your 5ml serum in a cool, dry place with the cap tightly closed to maintain formula stability. Frequently Asked Questions About Multi-Peptide Lash & Brow Serum How long does one tube/bottle typically last with twice-daily use? With proper twice-daily application of a thin layer, the 5ml bottle is designed to last approximately 3 months. This duration aligns perfectly with the recommended 8+ week usage period needed to see the full transformation of your lashes and brows. Can I use this serum if I have eyelash extensions or get lash lifts/tints? You should always consult your lash technician first. While it is generally safe for the brow area, for lash extensions, applying only to the skin of the lash line (avoiding the extensions themselves) may be acceptable, as the formula could affect adhesive. We recommend avoiding direct contact with lifted or tinted lashes. I've been using it for 3 weeks and don't see results yet. Is this normal? Yes, this is completely normal. Visible results typically appear within 4-6 weeks of consistent, twice-daily use, as the hair growth cycle takes time. For a full transformation, we recommend continuing daily use for at least 8 weeks without interruption. Is this product safe to use on the lower lash line as well? Yes, you can apply it along both the upper and lower lash lines. Use extreme care with the precision applicator to avoid direct contact with the eye. If any irritation occurs, discontinue use on the lower lash line. Do I need to stop using it after a certain period, or can I use it indefinitely? You can use it indefinitely to maintain your results. Once you achieve your desired lash and brow appearance, you may reduce application to once daily for maintenance. There is no recommended "cycling off" period for this peptide-powered serum. Can I apply my regular eye cream or makeup over this serum? Yes, you can apply other products over it, but you must allow the serum to dry completely first. Wait at least 2 minutes after application, then gently apply your eye cream, concealer, or makeup once the serum is fully absorbed. What is the difference between this and more expensive luxury lash serums? Our serum is powered by a multi-peptide complex to strengthen and support natural growth, and it is rigorously fragrance-free. It avoids prostaglandin analogs, which are common in many luxury or prescription serums and can have side effects, offering an effective, transparent formula at an accessible price. What does "patch test" mean and how do I do it for this product? A patch test involves applying a small amount to clean, dry skin on your neck or behind your ear for 3-5 days. For this eye-area product, also apply a tiny amount along a small section of your brow or temple to monitor for redness, itching, or swelling before full application.
