I Think These 10 Prime Day Beauty Deals Are The Ones You *Need* To See

Promising review: "I just had to write a review because for years I’ve suffered from severe chapped lips no matter the season. I’ve spent hundreds of dollars searching for a product that would help prevent or even soften my lips, without success until now. Immediately after putting this product on, I knew my search was over. And by day two, I knew I would be a customer for life. My lips stay moist from sunup to sundown, and it works perfectly as a base to lipsticks or my preference — long-wear lip color. I highly recommend this product for soft, chap-free lips." —Angela Austin

Price: $16.80 (originally $24; available in six scents)

This new model has an additional heat setting (low, high, cool, and *now* medium!). Plus, the head is detachable on this version for easier storage and transportation!

Promising review: "I wish I had discovered this sooner because it has saved me countless hours on blow drying, straightening, and curling my hair. I have extremely frizzy, wavy hair that has extremely kinky waves at the roots. Typically I let it air dry then spend about 30+ mins straightening and curling. If I must blow dry, it turns into a huge ball of frizz that requires even more time to straighten. I’m not skilled enough to use a round brush and blowdryer together, but that’s essentially what this tool is in one! After showering, spray in product (I love OGX Protecting + Silk Blowout Quick Drying Thermal Spray), let hair air dry 50-75%, then get to work! I use medium speed and it takes me less than 20 minutes, and I have A LOT of thick hair." —Heather R.

When applying, use the tip of the pen to create a thin line. For a bold, thicker line, apply with slightly more pressure.

Promising review: "Sheer perfection. Super easy to apply. I was never good with these type of eyeliners, but after reviewing this product I figured I will give it a try...and OMG...best eyeliner I ever owned. It goes on smooth with a sharp line, no messing up. From the first time I applied it I couldn't believe how well it worked. Cat-eye done in a second or two...No need to re-apply or fixing it later as it stays on nicely all day. I use it with the little black palette from Lorac, which came with primer, and I am not sure if that helps but I put my eye shadow on, then eyeliner and I am good to go. It stays put ALL DAY, just as the name promises. And as other reviewers mentioned, using this product you will be a pro in applying eyeliner in no time. That's how nicely it goes on. I can't say enough good things about it! I purchased one for my daughter and for my mom. They both love it. This will be my one and only eyeliner of choice. Thanks Stila for making a GREAT product...well worth the money! You just gained another loyal customer." —BeataR.

It has new packaging just FYI if it looks different when you order it! This is my all time fave, never-be-without night cream, and I'm wondering WHY did I just stock up for full price?!?!

Promising review: "I’ve been using the same cream for over 7 years. Every other cream would break me out, not moisturize my skin enough, or just make me too oily. I got this because I’ve been breaking out and I’ve been trying to find something to calm my skin down. The first night I used this my skin improved!! Redness/bumps reduced, my skin was soft. I have very sensitive, oily, acne prone skin and this did not irritate my face at all. I wake up and my skin is soooo soft. My skin texture has drastically changed in just a week. My makeup applies so smooth and my pores even look better. My new go-to!" —Melody

Price: $14.48 (originally $21.99)

Caffeine has a number of skincare benefits, including brightening and temporarily reducing the appearance of stretch marks and cellulite, if that's something you're looking to do! You can read more about the skincare benefits of caffeine at the Cleveland Clinic.

Promising review: "OBSESSED. I can't say enough great things about this lotion. Don't hesitate, just buy" —Summer

Promising review: "Where has this been all my life? I have been using this for maybe three days now, and putting it on in the morning and evening are the best parts of my day. The description of the scent as "pistachio, salted caramel, and vanilla" does not even begin to describe the incredibly decadent smell of this cream on my skin. My skin feels like velvet and I saw improvements in the texture after the first application. I will use it for the rest of my life. Do not ever discontinue this! I did not expect to be so amazed my this cream, but it is life-changing. Buy it! You won't regret it." —Michelle Brown

Price $38.40 (originally $48).

And if (when) you do fall in love with the scent, they make tons of other products, including a fragrance!

Promising review: "This is hands-down the best face oil I've ever used. It makes my skin glowy and foundation goes over it like a dream. The fragrance — I love how it smells, but I can see how some people might be put off by it. I tried the Sunday Riley Juno Face Oil because there was a deal on it, but it's not the same. I will always buy this oil. I have to hide it from my boyfriend because he also likes to put it on his beard." —Sarah

Price: $28 (originally $40)
