Rodan and Fields Lash Boost vs. Mary Kay eyelash serum – How do they compare to one another?

Ingredients

Rodan and Fields nightly-eyelash boost serum is a lash conditioner that features a unique proprietary formula which aids in enhancing lash length and volume in a matter of weeks. The growth serum contains Panthenol to keep your eyelashes moisturized, biotin, and keratin for strengthening the lashes, as well as a peptide complex which nourishes the lash follicles. Unlike Latisse, this serum is not a prescription product, thus easily accessible by women looking for fuller, longer, and healthier lashes.

Mary Kay Lash and Brow serum consists of a safe and non-drug formula, which contains the refreshing Lash Response complex. This key ingredient contains amino acids for lash nourishment and red clover extracts to neutralize free radicals which may react with sensitive skin.

Application

To use the Rodan and Fields lash boost is quite straightforward. Apply the nightly eyelash-conditioning serum on completely dry and clean upper lash lines and wipe off any excess serum from the brush before applying. Wait at least 90 seconds before sleeping or utilizing any other eye products for the serum to dry. You can also use this serum on eyebrows for improved appearance and thicker eyebrows.

Mary Kay Lash and Brow serum is also applied at night, just like you would use your eyeliner. Ensure your face does not have any make-up and is absolutely dry. Pay more attention to sparse or bare areas between your eyelashes. If you use it on eyebrows too, ensure you apply the formula in the direction of hair growth.

Results

R+F recommends using the Lash Boost at night for eight weeks for full results. However, within four weeks of using this serum, I had already begun to see results. The 8-week timeframe also applies to your eyebrows if you apply it to the brow area.

Mary Kay Lash and Brow serum transforms your problem brows and lashes into healthy and thicker ones just within 30 days. By strictly adhering to its daily nightly routine application, you will enjoy voluminous and natural-looking eyelashes and brows in no time.

Rodan and Fields Lash Boost Overview and Key features

Rodan and Fields, also referred to as R+F, is popularly known due to its Proactiv brand. In 2016, the brand released its Lash Boost product to compete with other eyelash enhancement formulas in the market. With a blend of keratin, biotin, and a peptide complex, this product reveals results in merely 4-8 weeks and your eyelashes will no longer require mascara.

Lash Boost also contains the controversial isopropyl cloprostenate ingredient, which is known to induce side effects such as eye irritation, redness or tingling of your eyes and your lashes may darken. To find out if your skin will react with the product, R+F recommends either performing a patch test or by reducing the frequency of application of the Lash Boost.

Frequently Asked Questions

Are Lash serums safe to use?

The eye is quite a delicate organ on the human body. Despite genuine lash serums having FDA approval, you may find your eye, or the skin surrounding them, reacting to some products. To avoid this, perform a patch test or reduce the rate of application of the product.

Does eyelash growth serum work?

Eyelash growth serums are expertly tested and must be FDA approved. Ingredients such as collagen, antioxidants, peptides, and protein are proven to cause eyelash growth, and at times eyebrow hair growth.

What is lash enhancement?

It is a procedure which involves tattooing an ultra-thin black line along the lash line to create a more defining eye with fuller, longer and thicker eyelashes. Also known as invisible eyeliner, this procedure is an excellent solution with sparse lashes or with alopecia.
