We at Red Lotus Lash Extensions in Portland, Oregon highly recommend Jan Marini: Marini Lash. The reason we recommend this is because of the results you can see from the product. By using this, your natural eyelashes will grow and thicken providing a better base for your extensions and more healthy lashes to attach extensions to. The product contains peptides and lash conditioning ingredients to help promote healthier lashes. Marini Lash has been tested by ophthalmologists and dermatologists for safety. The differences between Marini Lash and Latisse are that Marini lash uses peptides instead prostaglandin analog which can be irritating and cause side effects. Marini Lash is also very inexpensive compared to other brands promising better eyelashes.
