    2. For Lashes
      For Lashes - Apply only one stroke of ADVANCED. byK Lash Serum at the root of your upper lashes once a day (similar to using an eyeliner). Do not over apply.
      For Brows
      Apply every night directly to the skin at the base of the eyebrows using the accompanying applicator.

       

    3. Let the product completely dry before applying other eye cosmetics.

  • We recommend applying it at night after removing contact lenses.

  • ADVANCED. byK Lash&Brow Growth Serum has not been tested on pregnant or breastfeeding mothers. Please consult with your physician first.

  • You should always consult with your physician or other health care professional. It is recommended that you wait 6 months after your last chemotherapy treatment before using ADVANCED. byK.

  • YES!! You can use ADVANCED. byK, but please allow two days for the adhesive to fully cure after extensions have been applied.

    ADVANCED. byK should be applied to the lash line, not on the lashes. By applying ADVANCED. byK, the active ingredients strengthen and lengthen your own lashes and protect them from the weight of the glue and extensions in order to hold the extensions firm. The active ingredients also help to maintain strong, healthy lashes by moisturising dry lashes after a lash lift, as well as nourishing the follicles.

  • Yes!! ADVANCED. byK is safe to use. However, as with any cosmetic product, some users may be allergic to one or more of the ingredients. If an allergic reaction occurs, discontinue use.

    A patch test is also recommended. Apply a small amount of the serum onto a clean area, such as the inside of the arm, behind the ear, or on the side of the neck (ensure that the skin is free of other products so that you can test this product effectively). After 24 hours, check to see if no adverse reactions occur.

    Although the ingredients in ADVANCED. byK are gentle on the skin, a few people may exhibit mild sensitivity at the start of use. Once the eye area has returned to normal, you can resume use every two days. It may take a little longer to show results, but the effects will continue. If the eye area is still sensitive to the product, we recommend discontinuing use.

  • Yes. Hormone Free, Prostaglandin Free, Vegan, Gluten Free and Cruelty Free.

     

    Our product contains no ingredients that rapidly lengthen hairs as these often have a side effect of thinning or deforming the hairs. All natural ingredients are used, and the concentration of active ingredients has been optimally adjusted.

  • The time it takes to see results depends on the growth cycle of your lashes and eyebrows when you start using the product. It generally takes 8-12 weeks to see good results, so you need to persevere. If you do not see results after 12 weeks of continuous use, you have the right to claim a money-back guarantee (see Money-Back Guarantee for more information). It is very important that you use the product correctly and follow the instructions.

  • Our ADVANCED. byK Lash&Brow Growth Serum size is 3ml. This will last approximately 3 months.

  • Please understand that we cannot accept returns as we are unable to determine if the product has been used or not. As it is the customer's responsibility to check the product description and ingredients, Lash Advance (ADVANCED. byK Lash&Brow Growth Serum) reserves the right to refuse returns for reasons such as a 'change of mind'. However, if you have any questions prior to purchasing, please contact us at info@lashadvance.com.au

     

    We do not offer a refund guarantee in relation to allergic reactions. As with any cosmetic product, users may be sensitive or allergic to one or more of the ingredients. If you have sensitive skin, please consult your dermatologist before purchasing.

  • Money back guarantee: If no results are seen after 12 weeks, we offer a 100% money-back guarantee. We ask for before and after photos, facing upwards and downwards with your natural lashes clearly visible, a dated screenshot from your camera roll for proof, and a video of you applying the product to ensure that we can scrutinise the suitability of its use.

    Email these photos, video and receipt of purchase to: info@lashadvance.com.au

    Our team will process your application afterwards. Please allow approximately 3-5 working days for a reply.

    Please ensure that the photos have a valid date and time stamp (camera roll screenshots only).

    Please also ensure that both before and after images are free of make-up and mascara.

    The money-back guarantee must be applied for within four months of receipt of the product.

    Failure to meet this criterion will result in no refund being authorised. We reserve the right to refuse refund claims if we are not satisfied with the supporting evidence provided.

    The money-back guarantee only applies to the first purchase of one bottle. Wholesale purchases are not eligible for the money-back guarantee.

     

    To see maximum results, please use the serum every night for 12 weeks.
