How To Use Peter Thomas Roth Instant FIRMx Glow-Filter Priming Serum

1. Apply to clean, dry skin as the last step in your skincare routine, before makeup. Use daily in the morning and as needed.
2. Smooth an even layer over the face, focusing on areas where you want extra glow and definition such as cheeks, chin and jawline.
3. Wear alone for an instant glow-filtered finish, or follow with foundation and other makeup for a lit-from-within look.

Pro Tip (from estheticians): For the most seamless makeup application, allow the serum to fully absorb for a minute before applying foundation, and press it gently into areas where you want extra blur instead of rubbing.

FAQs

Can I use this while pregnant or nursing?
The brand does not provide specific pregnancy or nursing guidance for this product. Please consult your physician before use if you are pregnant or breastfeeding.

Can I use this with retinol/retinal/acid exfoliants?
There is no explicit restriction listed, but because this is an active priming serum, introduce it slowly when using other potent treatments and monitor your skin for sensitivity.

Is it suitable for sensitive skin?
The formula is designed for most skin types. If your skin is very sensitive, patch-test on a small area and start with less frequent use.

How long until I see results?
The glow-filter and blurring effects are immediate, while clinically measured firmness benefits were observed in as little as 1 week with continued daily use.

Can I use it around the eyes?
The product is intended for the face. Avoid applying too close to the immediate eye area or lash line unless your eye area tolerates it well.

Storage and shelf life?
Store tightly closed in a cool, dry place away from direct sunlight. Refer to the packaging for the PAO (period-after-opening) symbol for best-use timing.
