BEWARE!
The active ingredient Avobenzone is photounstable in the presence of Octinoxate alone. This means the sunscreen molecules that protect your skin are damaged by sunlight themselves. As a result, the sunscreen becomes less protective. A stabilizing agent can help significantly slow down this process. But the Jack Black Intense Therapy Lip Balm SPF 25 does not employ such a stabilizer.
Honestly, if Jack Black lacks this basic knowledge about sunscreens, I feel I can't trust any of their products.

My lips have been super-distressed all winter, generally just feeling dry and tight on the outside and occasionally developing hard patches that I just cannot help but pick at. Consequently, I've been buying a lot of lip products to fix it! I'm trying to stay away from petroleum-based products and I was hoping to find a balm with some SPF. I bought this Jack Black lip balm based on all of the good reviews here. It was a bit pricey for a lip balm, but I figured that anything that could fix my lips would be worth it.
The packaging is cute, although small for the price. It is small enough to put in my pocket, but I don't advise that; since the balm is a bit liquid, your body heat is enough to make it gush out, and then you waste a bunch of expensive product. Luckily, a little does go a long way. I'm not a huge fan of the applicator tip; it is too small to apply directly to my lips and distribute product evenly, so I usually just put it on my finger.
I love the lemon and chamomile scent. The product feels nice on my lips, although once the slick feeling goes away, I'm not sure that I can say my lips feel more moisturized. Instead, I am just applying this stuff constantly. I'm pretty balm-addicted, but I can usually get through most of a year with one stick; I have only had this since late December, and it is almost gone, so that's not even three months of use. Once you get to the end, it is hard to get product out of the tube. I think I just like stick balms better!
My biggest disappointment is just that this did not noticeably improve my lips. When the balm wears off, they still feel dry and tight. This might be good to use when my lips are back to normal (which is why I said I would repurchase), but it is not a magic healing product. I think I am going to give up on the natural approach for now and hit 'em with neosporin.

I really really like this balm but can't really get over the smell of this one. It smells like a lemon Skittle, very sweet and a bit much. Texture however, is perfection.

This is my favourite lip balm ever. It makes my lips so soft, even during the harsh winter. The smell is amazing, to me it's lemon meringue pie. I also like the packaging because I can convince my boyfriend to use it, it doesn't look girly at all. However, the best part is the ingredient list, it's natural and full of good stuff. Would repurchase.

The absolute best lip balm out there. I know it's a mens brand, technically, but I could care less!! Always keeps my lips as moist and unchapped as if they were brand new! I swear they look photoshopped using this balm. It doesn't have a taste, but the smell is lovely. I always think it's like lemon poppyseed muffins. It's not glossy like the C.O. Bigelows, and I don't find it to be sticky either. Like if you're out in the wind and your hair blows into your lips, you aren't going to have sticky strands of lipgloss hair now. It is balmy, so more texture than you'd find opposed to Chapstick, but not to glossy territory (if that makes sense...) It's great year round and is really, honestly, the most perfect lip balm I've ever used. I like the grapefruit flavor as well. I don't care for the blackberry/black tea or the lavender/vanilla formulas, the smell/flavor of those is more pungent. I can't place the BB one, but it's a familiar flavor. I definitely taste that one more than the lemon one. Or maybe the scent is so strong I think I taste it. The LV one reminds me of Carmex. Not always a bad thing, but I'd rather have lemon poppyseed muffins than Carmex. :) This balm is worth every penny and more and lasts a good long time too! Even with multiple daily use!!

This is the lip product I put on first in the day. My morning commute is the longest amount of time that I'm outside on an average day so I like to wear this when I make the walk, for the sun protection. I love the smell and the not too glossy look of this lip balm. However, as a moisturizing lip balm I don't think it's essentially any different than Aquaphor. The texture is very similar. So if you care about sun protection and can spend 8 bucks for lip balm this is great, if not I would recommend Aquaphor!

The dry Alberta winter has unfortunately come back again and has brought with it the dry cold winds that dry my lips out without a doubt. Bought this balm on a whim this weekend a Sephora. It was a little steep ($7.99 CAD) for such a small tube but it has made a difference within minutes of applying it. I will buy it again, I just wish that the tube was a little bigger for the price.

This is the most expensive little tube of lip balm i've ever had but the ingredients list is magically healing and so... ugh just love it ! THIS particular balm has an spf of 25, a MUST for the health of your lips, yet it tastes NOTHING like sunscreen, it smells exactly like a lemon bar. DELICIOUS. i love it love it love it. the ingredients list is minimal, narrowed down to a few healthy ingredients to really condition those lips. It has a gorgeous slip to it which makes your lips feel silky and makes them look hydrated and healthy. not overly done or glossy, in case any of you --guys are wondering about this. If you do want a bit more glossy look,-- ladies just add more it definitely adds a shine to the lips. Wears wonderfully over OR under a lip color, too! it comes in a blue squeeze tube with a convenient applicator shaped opening to contour the lips. The sunscreens in this are broad-spectrum which is a plus, better than Fresh's sugar with Oxybenzone (studies have shown that this active actually breaks down in sunlight and causes more DNA damage than it helps protect! scary...) the Octinoxate is a so-so stabilizer for avobenzone. i would've liked to see Zinc Oxide in here as the active, as it is more stable than avobenzone... but oh well ! i digress. this is a lovely lip balm, a bit pricey at nearly 8 bucks a pop but they do last a long time ! just LOOK at that ingredients list ! Only 8 ingredients in this, two of which are the sunscreens, chemicals.. the other 6 are the replenishing oils and butters! you can't ask for a more perfect formulation! well,... the sunscreen maybe but anyway... i DO plan to repurchase and even experiment with new flavors, i already have tried this in mint (didnt care for), black tea (purple label--loved!!!) and grapefruit(pink label-smells exactly like grapefruit).
Active Ingredients: Octinoxate: 7.50%, Avobenzone: 3%.
Other Ingredients: Butyrospermum Parkii (Shea Butter) Fruit, Persea Gratissima (Avocado) Oil, Camellia Sinesis (Green Tea) Leaf Extract, Tocopheryl Acetate (vitamin E), Citrus Medica Limonum (Lemon) Peel Oil, Anthemis Nobilis (Chamomile) Flower Oil

EDIT: HUGE food for thought. !! This isn't as protective as I thought . ANY citrus oil - grapefruit lemon orange etc- has been shone to be PHOTOTOXIC when exposed to uv radiation , this means your lips are being bombarded with free radicals :( that's a huge minus for this flavor
For the lip balms overall the combination of avobenzone and octinoxate is a HORRIBLE combination for sun protection. Just google 'avobenzone octinoxate unstable' and you'll come across NUMerous pages of research showing that avobenzone -unstable on its own- has shone even faster degradation when combined with octinoxate . So in other words these two sunscreen agents are bad enough alone -not broad spectrum- but they're worse together ... I want to keep my lips healthy and youthful thank you!!!
I will continue to search for a better sunscreen-ed balm.
Lowered my rating from 5 to 2 . I hate to have to do this. I really do ...

I have very dry lips and get cold sores every now and then. I've been using the Original Carmex Jar for years now and am happy with it. However, when a friend raved about Jack Black and told me it's better than Carmex, I had to buy a tube to try.
Considering how it's about 8.5 times the price of Carmex, I kinda expected it to knock me off my feet.
Unfortunately:
1) I find the smell of Lemon & Camomile too sweet in an artificial way.
2) Don't see how it's much more effective than Carmex
3) Don't think it'll work if I'm having a cold sore
How Jack Black is better than Original Carmex Jar:
1) Packaging. It's more hygenic than the Original Carmex Jar. (The formula in the Original Carmex Tube doesn't work the way it does in the Jar)
2) It's got SPF25
Won't be repurchasing Jack Black cos I think Carmex is better and way cheaper! continued >>

I love this stuff! It immediately repairs dry lips, smells great, and lasts longer than any lip gloss. The only caveat is that it is rather small for 8$ but honestly for how it moisturizers (and how my fiancée loves it because it smells like lemon tart)

I love all the Jack Black lip balms.. they are very moisturizing and once they wear off you don't feel dry. Recc the mint, lemon and the lavendar all super nice.

Now this is what i would call a great lip treatment! Its just my kind of thing - natural ingredients, decent SPF and a unique lemon-y flavor. The spf25 is decent enough for our hot Florida climate and it smells and tastes refreshing! This works better than other lip balms/treatments that are double and triple the price. Oh and did i mention it actually works?! Very minor gripe is the tube it comes in (always gotta cut in half to get the last of it out) but thats so minor you can forget i just mentioned it! HG.

Just adding to the positive reviews here. This lip balm is amazing. It makes your lips feel soft, but you don't feel like you're "addicted" to it like you do with other lip balms. At first I was a bit afraid to try it since another lip balm with SPF made my lips crack horribly, luckily I've had no such problem with this balm.

I wasn't expecting it to smell so yummy, since all the fragrance is natural, but they really hit the right mix. I agree it smells like lemon meringue. I'm sensitive to mint so I'm happy all the different scents have their own essential oil blend. I did get the mint for my male housemate though and he likes it.

I usually have perpetually flaky lips which leads to excessive exfoliation and then more flakes, but this is really healing my lips and making wearing lip colors so much easier. I don't think I'll ever go back to wax based lip products again.

Oh my dear Lord...Let me put it this way. I have the habit of collecting makeup, and I have more makeup than I can ever use up in this life. But amongst all these insane obsession with cosmetics, my most psychotic problem is my lip balm obsession. I have so many I can open a lip balm store with a considerable amount of display. And among ALL these lipbalms, this particular one, this Jack Black Lemon Chamomile is the ONLY one I actually used up. The other one close to being used up is Softlips French Vanilla, but that one has only like 2g of product. This Jack Black lip balm contains 7g product for $7.50 in Canada, recently Sephora bumped up the price again to $8.50, but I'll buy this again and again until I die. It is the most moisturizing, most long-lasting, best texture and bext flavour of all lip balms in this world. (I can safely make this conclusion with no objections considering the amount of lip balms I possess.) It is the ONLY thing, that when your lips are dry, it actually heals them, instead of temporarily moisturize them. It also has SPF 25, and a flawless ingredients list. Glorious under lipgloss or over lipsticks. Overall, definitely most DEFINITELY HG lip balm. Ugly tube, gorgeous balm. =)

It's taken me many years and many wasted dollars to find this lip balm. My lips are very troublesome. On the one hand, they're very pigmented and full for my taste, so I like to play them down with nude lipstick. On the other hand, they're sensitive and prone to dryness and peeling, and we all know how nude lipsticks highlight flaky lips.
Even the most basic balms wreak havoc on my lips, leaving them dry and cracked or broken out in tiny little bumps. This is a five star product because it doesn't do either to me. You'd be surprised at how rare that is.
Yes it is expensive, but I do think it's worth it. The flavor is incredible, and the finish is lovely on its own but plays well with my lipsticks and glosses. I do use a different balm at night to cut down on waste, however.

This is an adequate lip balm. Has quite a matte finish, and smells nice and lemony. It feels quite thick on the lips, and moisturises quite well, but not as well as many other lip balms I've tried.
I find it rather expensive for a lip balm - perhaps this is because of the spf? Overall, I much prefer Carmex - it is much more effective on me, and is much cheaper. I will probably use this up on holidays. I won't repurchase.

Perfection in a tube.

This stuff is a bit pricey for a balm, but it's really wonderful stuff. It smells amazing and moisturizes really well. I absolutely LOVE the package too, it's so cute. The reason that I can't give this five lippies is because this product actually belongs to my husband. I use it from time to time, so I know full well how it performs. However, as this product is geared toward men I find it to be a bit on the shiny side. (So does DH. He feels self-conscious wearing out out in public.) Overall it's still a great product and we will both continue using it, but I wish it were less glossy.

So bought this lip balm at Sephora for about 8 to 9 dollars and I must say I absolutely love this lip balm. I believe I have found my Holy Grail lip balm! This lip balm glides on smoothly and effortlessly, and after futile attempts at replenishing and curing my dry, cracked lips, I tried to give this a shot. It contains lots of healthy oils like shea, avocado and almond, and it smells heavenly. Its a nice, sweet smell but not overpowering. This even trumps the olive oil on lips trick because I did that once and I actually woke up to cracked lips. The mini one is about 7 grams. The ackaging is really nice, and because its in a tube its more hygenic than a pot. Iactually spotted this on Sephoras top picks list for the lips and though its made for men it seems like women are buying it more. Also, this lip balm was trumped by Laura Mercier's Flawless Skin Lip Silk, but I disagree. This lip balm has done so much more for me, and at a fraction of the cost, as Laura Merciers lip silk was 26 dollars, and this one was just 8, which is amazing because this lip balm cured my dry and cracked lips ( which were made worse after the laura mercier stuff). Overall, I loved it. Its a reasonable price, has great flavours, and does wonders for your lips!

This lip balm is fantastic! Super moisturizing without being sticky and it leaves my lips with a nice subtle gloss. A little bit goes a long way and I've seen better results with this stuff in two days than I have with other products in a week! I was hesitant to believe this product's hype but I'll be the first to admit I was wrong. A tad pricey but good quality stuff never comes cheap, this is money well spent. The scent is amazing, it smells just like lemon meringue pie filling. My only complaint is that we don't have the SPF formula in Canada, I plan on trying to find it while in the US this summer.
