    Love It

    This is a new favourite for me - it’s comforting on the lips it’s not flavoured or heavy and can be used anytime. Brilliant and it works without sting or strong flavours. A must have for me. My new favourite lip product! And I think I must have tried almost everything!

    Ruined my lips

    I used this product before, but recently, with two applications this product made my lips burn, dry, cracked, and now peeling on day two after using it again. It seems I have developed an allergy to it over time. I am slathering my lips in unpetroleum every two hours to stop the now itchiness and burning and to hopefully heal them quickly. This product is already in the trash!

    Hi Stef, we are so sorry to read this - burning, cracking, peeling and itching lips sounds awful and we completely understand how distressing this must be. We're really sorry you're going through this.
    It is possible to develop a sensitivity to an ingredient over time even if you've used a product before without any issues, and we take this extremely seriously.
    If the irritation and peeling persist, we'd strongly encourage you to seek advice from a pharmacist or medical professional to make sure your lips heal properly.
    Please also reach out to our Customer Experience Team directly at help@theinkeylist.com — we want to look into this properly and make sure you are fully taken care of. This is absolutely not the experience we ever want anyone to have. 💙
