NULASTIN

The serum should not stop working and there is no evidence clinically that would suggest individuals become immune to the formula. However, because our biology is unique and our systems are constantly going through phases of growth and repair, stress and life, we have noticed that there are seasons when visible changes like less robust growth occurs. Our Founder and CEO, Leah Garcia has been a go-to for understanding the ebb and flow of results. For example, she too experienced a time-period after using the serum for over two years when her lashes were just not responding as magnificently. She stopped using the formula for 30 or so days and then, re-introduced it. Her lashes not only kicked into another natural growth-spurt, they came in luxuriously feathery and symmetrical. We don't have a definitive timeline on how long to rest, and there is nothing scientific about this troubleshooting tip. It's just a bit of real world creativity.

Hello Alex, Thanks for checking in. We do not have a prostaglandin in our formula and the ingredients are completely different than the prescription brand you mentioned. Uniquely we have five DNA proteins that outperform the aforementioned ingredient. Our synergistic formula addresses all four stages of lash/brow growth, which is why our results are natural, beautiful and ongoing. As for allergies, our clinical evaluation revealed no dermal irritation. However, in the marketplace, we have had a few woman who have experienced mild irritation. Our product is made fresh and in small batches, so we recommend a patch test if you are concerned. We have a 100% performance guarantee, less S&H, so know that we'll take care of you if the product does not work to your satisfaction. Best, Leah Garcia, Founder & CEO

The product should not cause discomfort. It is a topical application. However, some individuals have very sensitive eyes. Other's experience allergic reactions to any number of cosmetic ingredients. Oftentimes, it's possible to stop using the product for a week or so until the eyes calm down and then reintroduce the serum once per day using a very very light application. Our recommendation to those with sensitive eyes is to use the serum morning only (and not at night before bed), as the eyes seem to respond better. One quick note on application it is best to use the serum on the base of the upper eyelashes starting from the inner to the outer corner of the eye. Do not apply it to the bottom lashes. To avoid discomfort, it should not touch the eye.

Hi Beth, great question. Our BROW serum is fragrance free, so no need to worry! If you have any additional questions feel free to email us at customercare@nulastin.com.

You should continue using the product as an ongoing part of your daily routine. If you discontinue use, your skin, lashes, brows, and hair will gradually revert back to their original appearance. The good news is that you can decrease usage after you've achieved a desired look. For LASH, BROW, and HAIR products: Once you reach a point of satisfaction, you can apply the serum once per day. Another option is to decrease application to three or four times per week. When you want to increase the results again, go back to using twice per day.

The serum should not stop working and there is no evidence clinically that would suggest individuals become immune to the formula.

We recommend keeping the unused serum in the refrigerator until you are ready to use it again, so the DNA proteins maintain their full potential. Please keep us posted on your progress.
