FAQs

Can I use this while pregnant or nursing?
The brand does not provide explicit guidance for use during pregnancy or nursing; since this product includes active smoothing technologies and peptide complexes, consult your physician before use.

Can I use this with retinol/retinal/acid exfoliants?
Yes—but because this formula includes active smoothing and plumping actives, layering multiple strong treatments at once may increase sensitivity. Use as directed and monitor how your lips respond.

Is it suitable for sensitive skin?
The formula is designed for normal, dry, combination and oily skin types. If your lips or surrounding area are highly sensitive or reactive, apply a thin amount initially and patch test before full use.

How long until I see results?
Some users notice smoother lips after the first application thanks to LineFill™ technology; fuller-looking lips and reduced lines become more visible with consistent use over days to weeks. 

Can I use it around the eyes?
No—this product is designed specifically for use on lips and lip lines. Avoid applying to the eye area or mucous membranes unless otherwise advised by your physician.

Storage and shelf life?
The brand does not publish a specific shelf-life timeframe; store the product in a cool, dry place away from direct sunlight and use within the period-after-opening (PAO) timeframe printed on packaging.
