Learn how to use the Lash & Lip Duo from Indeed Laboratories to enhance lashes, brows, and lips with a simple daily routine.
Quick answer
Use the Lash & Lip Duo twice daily—apply the lash serum to your lash line and brows, and the lip treatment to your lips—for visibly fuller lashes, brows, and lips over time.
Why consistency matters
The Lash & Lip Duo is designed to enhance your natural beauty with results that continue to improve over time. This means you won’t see a dramatic change overnight—instead, you’ll notice gradual improvements in lash length, thickness, and density, as well as a fuller-looking pout, with regular use.
Because the formula is prostaglandin-free, it works differently from some other lash serums. It focuses on strengthening hair follicles and repairing damage, which supports healthier growth over time. This makes it a gentler option, but it also means you need to be patient and consistent to see the best results.
Who should use the Lash & Lip Duo
The Lash & Lip Duo is a great choice if you want to enhance your natural lashes, brows, and lips without relying on makeup or invasive treatments. It’s especially useful if you’ve noticed sparse or brittle lashes, or if you want to add a subtle boost to your lip volume.
Since it’s prostaglandin-free, it may be suitable for people who are sensitive to traditional lash growth serums. However, it’s always a good idea to do a patch test before applying any new product near your eyes or on your lips.
How to use the Lash & Lip Duo
- Cleanse your face: Start with a clean, dry face. Remove all makeup, especially around your eyes and lips, so the products can absorb properly. Applying on a clean base helps prevent clogged follicles and improves absorption.
- Apply the lash and brow serum: Using the applicator, draw a thin line along your upper lash line, just like you would with eyeliner. Then brush the remaining serum through your brows. Avoid getting it in your eyes. Don’t over-apply—a thin layer is enough. Excess product can cause irritation.
- Apply the lip treatment: Squeeze a small amount of the lip treatment onto your finger or the applicator and spread it evenly over your lips. Let it absorb for a minute before eating or drinking. Reapply throughout the day as needed, but use it consistently for best results.
- Use twice daily: For optimal results, use the duo in the morning and at night. Consistency is key—make it part of your daily skincare routine. Set a reminder or pair it with another daily habit to avoid missing applications.
- Be patient: Results improve over time. Stick with the routine for at least a few weeks before expecting noticeable changes. Take progress photos every two weeks to track subtle improvements.
Product facts
- Lash & Lip Duo: The Lash & Lip Duo includes Peptalash™ II, a prostaglandin-free lash and brow serum that helps strengthen hair follicles to visibly increase length, thickness, and density. This means the serum works by supporting your natural hair growth cycle, so you can expect gradual, lasting improvements rather than a quick fix.
Lash & Lip Duo - Lash & Lip Duo: The formula contains plant stem cells, peptides, and panthenol to repair damage and prevent future breakage. These ingredients help keep lashes and brows healthy and resilient, reducing the risk of breakage as they grow longer.
