Rodan and Fields Lash Boost vs. SeneGence Lash Extend: Which is more effective?

Every woman looks forward to always having thick and full eyelashes as they are associated with beauty, youthfulness, and femininity. By using Rodan and Fields Lash Boost or SeneGence Lash Extend, you can quickly achieve this.

While growing up until my late 20s, I always had long and thick lashes that were the envy of all my peers. However, when I turned dirty 30 and gave birth to my firstborn, all this changed. My lashes became sparse, and they easily broke off as I applied my mascara. As such, I began wearing false lashes, which did more damage to my natural lashes. After a long and tedious search online, I found two eyelash serums, Rodan and Fields Lash Boost, and SeneGence Lash Extend, which promised to restore my beautiful lashes.

The following comparison review provides comprehensive details on what these two eyelash serums have to offer.

What are the differences between Rodan and Fields Lash Boost and SeneGence Lash Extend?

Rodan and Fields Lash Boost vs. SeneGence Lash Extend – How do they compare to one another?


Rodan and Fields Lash Boost serum features a unique proprietary formula ideal for quick lash growth. Its breakthrough formula consists of Panthenol and unique peptide technology, which nourishes your eyelashes, as well as keratin and biotin for strengthening them, thus increasing their length and thickness. In a matter of weeks, your lashes will be lush and 100% natural. For a full list of ingredients, visit the brand’s website.

Lash Extend from SeneGence consists of natural and patented ingredients such as Senepeptides which have anti-aging hair growth properties. These ingredients are combined with glycerin and water to stimulate gene expression, causing increased keratin production, which is good for the growth of hair follicles. The ingredients are also non-allergenic and non-irritating. This product is free of prostaglandins which are associated with adverse side effects.


According to the skin care line, apply Lash Boost along the upper lash line at night. Your face should be completely dry and make-up free before use. Be careful to wipe off any excess serum on the brush before applying it to your lashes, to prevent spreading it to the rest of your face. You can also use Lash Boost on eyebrows for increased hair growth.

Apply Lash Extend to the base of your eyelashes to facilitate the spread of the serum into and between them. Lash Extend Clear is for night use while Lash Extend Black and Brown serum is for morning application. Lash Extend Black and Brown is applied directly on the eyelid’s skin at the base of the eyelashes. Once you achieve your desired result, it is advisable to use the serum twice a day two or three times a week to maintain their long and thick nature.


Rodan and Fields Lash Boost provides long and luscious lashes in as little as four weeks if applied as directed. For maximum results, use the product for at least eight weeks to maintain lash volume and steady growth. The same timeframe applies when used on eyebrows for enhancing hair growth.

SeneGence Lash Extend guarantees at least 25% lash growth in as little as two weeks of use. If used according to the instructions and without combining it with any other eye serum, you will enjoy longer and fuller lashes as well as long-term results.
