lash boost vs latisse

We would all like to have long, lush eyelashes and so we apply mascara to give the appearance of more volume to our eyelashes, or we glue false ones on top of our own, or we even have expensive eyelash extensions attached.

The other, more recently available option to achieve longer, lusher eyelashes is to use an eyelash growth enhancer. Today we are looking at two of the most well known and popular brands of eyelash growth enhancers, Rodan + Fields’ Lash Boost and Allergan’s Latisse.

Latisse is an FDA approved clinical product which was accidentally discovered by some doctors during the use of a medication for the treatment of Glaucoma.

They noticed increased eyelash growth in their patients and scientists were able to isolate the compound responsible for the eyelash growth. This compound is called Bimatoprost and it is the active ingredient in Latisse.

Rodan+Fields’ Lash Boost on the other hand is not an FDA approved product and contains a number of active ingredients, including Biotin and Keratin.

Comparing Ingredients – Latisse vs Lashboost

So let us have a closer look at the ingredients of these two products. Latisse contains the active ingredient Bimatoprost ophthalmic solution (o.o3%) along with inactive ingredients:- benzalkonium chloride, sodium chloride, sodium phosphate, dibasic, citric acid and purified water, sodium hydroxide and/or hydrochloric acid to adjust the pH level which is 6.8-7.8 during shelf life.

Rodan+Fields’ Lash Boost on the other hand contains :-

Water/Aqua/Eau, butylene glycol, hydroxyethylcellulose, keratin, hydrolyzed keratin, biotin, sodium hyaluronate, isopropyl cloprostenate, ocatapeptide-2, allantoin, panthenol, copper tripeptide-1, pantethine, polypeptide-23, cucurbita pepo, glycerin, sea water, malus domestica fruit cell culture extract, hydrolyzed glycosaminoglycans, prunus amygdalus dulcis (sweet almond) extract, backhousia citriodora leaf oil, dipotassium glycyrrhizate, rhizobian gum, styrene/acrylates/ammonium methacrylate copolymer, xanthan gum, pvp, lecithin, peg-12 dimethicone, alcohol denat, chlorphenesin, phenoxyethanol, sorbic acid and sodium hydroxide.

As we can see there is quite a difference in the number of different ingredients in each product. Significantly more in the Rodan+Fields’ Lash Boost than are in Latisse.

Latisse has the FDA approved ingredient Bimatoprost which essentially means it has been tested for efficacy in clinical trials and is recognised as a therapeutically valid medication. Lash Boost on the other hand has primarily three active ingredients, Biotin, Keratin and Isopropyl Cloprostenate, which are not recognised by FDA as having medically therapeutic value.

This does not mean that they do not work, just that they have not been sealed with the FDA stamp of approval in clinical trials. Rodan+Fields have done their own research and trials which show that these ingredients do indeed work and lots of happy customers will certainly attest to the fact that they do.

What are the side effects of Lash Boost and Latisse.

All cosmetic products, whether FDA approved or not can have unwanted side-effects and especially when we are dealing with cosmetic treatment for the eyes and surrounding areas.

Eyes are very sensitive as we all know from personal experience and we should always take care when using a new cosmetic product, one that is new to us that is.

Latisse of course is only available on prescription and as such your doctor or medical professional will screen you for suitability in its use. Some of the most common side-effects that occur whilst using Latisse are itchiness and/or redness of the eyes, mild irritations that will stop when discontinuing use.

There are some more significant side-effects that can happen, including a darkening of the eyelids and darkening of the irises, these effects, again in most cases will stop on discontinuation of the product’s use.

You should also be aware that unequal growth can sometimes occur between each eye, for example your right eyelashes might become bushier and longer than your left eyelashes, or there might be a slight darkening of one eye’s lashes in contrast to the other.

Similarly with Lash Boost, itching/tingling and/or redness of the eyes can also occur, as can a darkening of the lashes, lids and surrounding skin of the eyes. Also rarely, a darkening of the irises themselves.

Always thoroughly check the ingredients of any cosmetic product you are using for the first time and with Rodan+Fields’ Lash Boost you will find that it contains almond extract, so nut allergists beware.

With both of these products you also need to be aware that they can cause unwanted hair growth in any area of skin that the product is applied, which certainly seems to suggest that they do indeed work.

Ease of use

Latisse comes in a little bottle along with a good supply of individually wrapped sterile applicators, one for each day’s use. The serum is applied with the applicators to the top of the upper eyelids, along the eyelash line. Lash Boost comes as a compact, mascara-like, all in one tube of serum and applicator.

Again you simply apply to the upper eyelids along the eyelash line. Personally I like Rodan+Fields’ self-contained applicator, it just feels less fiddly than having to unwrap the Latisse applicator and dip it in the separate bottle, although many of you may prefer to have the option of a fresh sterile applicator for each use.

How long do they take to work

Latisse takes typically 4-6 weeks for appreciable growth to appear, whereas with Lash Boost you are likely to start seeing results within 2-4 weeks. With both products it is recommended to continue regular use in order to maintain your eyelashes increased growth and thickness.

With Latisse, generally it would seem to have a longer lasting effect than Lash Boost, that is to say, that if you stop applying Latisse, your lashes are more likely to remain longer and fuller for a longer period of time. When you stop using Lash Boost your eyelashes are likely to return to their former selves quite quickly.

Final Thoughts about lash boost and latisse

If you are finding that mascara is not working for you and you do not want the fiddliness and faff of artificial eyelashes, or the considerable expense of eyelash extensions, then eyelash growth products are an affordable, although by no means cheap alternative.

Lash boost and lash boost products can both be a welcoming product to try if you are losing eyelashes.

For most people they seem to work well enough and will have little by way of significant side effects. They are certainly not an overnight miracle and take some time to work, so patience is required. I have known of people applying mascara whilst waiting for the effects to happen.

This is not recommended and you need to commit to a 2-4 weeks wait or longer. Once your lashes have responded to the growth serums you will need to continue using them to maintain your new long, lush eyelashes.

I would also add that eyelash growth serums will also stimulate hair growth in other areas of the skin, so they will also work on the eyebrows, but also anywhere else you allow the serums to soak into the skin regularly, so careful application is advised.

Latisse(Bimatoprost) is FDA approved and available on prescription only, you are likely to start seeing results in 4-6 weeks and that new growth is likely to last well, although you do need to keep using regularly. Rodan+Fields’ Lash Boost is available over the counter, although limited to Rodan+Fields themselves or licensed distributors.

You should see results sooner with Lash Boost, in as little as 2 weeks, but discontinuing use you are also likely to see your lashes return to their normal condition sooner as well.

I would also add that if you are nut allergic or suffer generally with sensitivity of the eyes and skin, that Lash Boost does contain almond extracts and also has a lot more potentially irritating ingredients than Latisse.
