WHEN IN THE ROUTINE WOULD I USE POLYGLUTAMIC ACID? Polyglutamic Acid can be applied both AM and PM in your ‘Treat’ Step as last serum before moisturizer.

CAN I LAYER POLYGLUTAMIC ACID WITH OTHER INGREDIENTS? Yes! You can safely use it with all other ingredients both AM and PM. What products should I not layer together? >

WHEN LAYERING THIS SERUM WITH OTHER SERUMS, WHICH SHOULD GO FIRST? Other serums should be layered first, and Polyglutamic Acid should be the last step before your moisturizer. Tip: Polyglutamic Acid Serum also can be added to foundation for an extra dewy glow.

DO I NEED TO USE A MOISTURIZER OVER THE TOP OF THE POLYGLUTAMIC ACID? You can follow with a moisturizer on top if you prefer.

IS POLYGLUTAMIC ACID SERUM SUITABLE FOR SENSITIVE SKIN? Yes, this serum is suitable for sensitive skin.

WHAT DOES POLYGLUTAMIC ACID DO? Our Polyglutamic Acid Serum sits on the surface of the skin creating a thin, breathable film. This helps lock in the moisture below, plumping the skin while smoothing away the appearance of fine lines and wrinkles and also helping to brighten the skin.

WHAT'S THE % OF POLYGLUTAMIC ACID? There's 3% Polyglutamic Complex in the formula.

WHAT IS THE PH LEVEL OF THIS PRODUCT? PH LEVEL: 6.0-7.0

DO I STILL NEED TO USE HYALURONIC ACID IF I AM USING POLYGLUTAMIC ACID? Yes! These two products work well together. Hyaluronic Acid Serum is a humectant that works to draw in moisture to the skin. Polyglutamic Acid Serum will help lock in the moisture. 

IS THIS MORE HYDRATING THAT HYALURONIC ACID? SHOULD THESE BE USED TOGETHER? Hyaluronic Acid Serum sits below the surface and Polyglutamic Acid Serum sits on top of the skin. Preventing any moisture loss. These can be used together as Hyaluronic Acid Serum would go straight after cleansing and sinks below the surface and Polyglutamic Acid Serum should be applied before moisturizer, laying on top of the skin, preventing moisture loss

HYDRATING VS MOISTURIZING - WHAT’S THE DIFFERENCE? Hydrators work to increase the water content of the skin and target dehydrated skin. Moisturizers help seal moisture into the skin and target dry skin.

WHAT’S THE DIFFERENCE BETWEEN DEHYDRATED SKIN AND DRY SKIN? Dehydrated skin is caused by lack of water and can leave skin dull. Dry skin is caused by a lack of oil and leaves skin feeling tight and flaky. How to tell if your skin is dehydrated >

HOW LONG WILL IT TAKE TO SEE RESULTS? Products can take up to six weeks to show full results, due to the time it takes for your skin cells to turnover and the results of any products to reach the surface. Consistency is key, so apply regularly even if you’re not seeing the effects straight away. It can be very tempting to increase use of some products to try and see quicker results, don't overdo it though. More is not necessarily more, and overuse can cause irritation and sensitivity.

IS POLYGLUTAMIC ACID SERUM PRODUCT VEGAN? Yes! This product contains no animal derivatives and is now certified by The Vegan Society.

IS POLYGLUTAMIC ACID SERUM SAFE FOR THOSE WHO ARE PREGNANT OR BREASTFEEDING? Yes! You can safely use it when pregnant or breastfeeding. Your guide to pregnancy safe skincare >
