24-hour Moisture Boost Polyglutamic Conditioning Lip Serum

The Science

Working to be 10 times more hydrating than Hyaluronic Acid and far more elastic than Collagen, Polyglutamic Acid aims to lock in moisture, aiming to give you softer, more supple skin whilst diminishing the appearance of fine lines and wrinkles.

Hyaluronic Acid aims to penetrate deep into the skin to hydrate and instantly help improve the appearance of fine lines and wrinkles.

- Works to gently exfoliate dry skin on the lips

- Aims to foster softened and supple lips

- Works to intensely hydrate

- Helps reduce the appearance of fine lines and wrinkles around the mouth area

A True Beauty Ritual

Getting the most from your 24-hour Moisture Boost Polyglutamic Conditioning Lip Serum:

1. Apply a generous amount of the serum onto the back of your clean hand using the doe-foot applicator.

2. With clean hands, gently smooth onto the lips using your ring finger, starting at the centre of the lips and working outwards.

3. Glide your fingertip across the lips to allow any remaining serum to be absorbed.

#AvantTips: Always start with a lip scrub to remove dry skin. This prevents your lipstick from looking patchy or flaky.

Always carry out a 24-hour patch test before the first use. Store in a cool and dry place.
