Prime Big Deal Days is here, offering discounts on beauty during the 48-hour sale, exclusive to Prime members. You can also find deals on sneakers, tech, pets and more.

I frequently cover shopping events like Prime Day, Black Friday and Cyber Monday as a writer for NBC Select, so I know how to find deals that are actually worth buying. I spent weeks combing through thousands of discounts to find the best October Prime Day beauty deals — each one I recommend below is highly rated, at least 20% off and at its lowest price in at least three months. I’ll frequently update this list throughout Prime Big Deal Days.

Cosrx Advanced Snail 96 Mucin Power Essence

4.6-star average rating from 71,461 reviews on Amazon

This expert-recommended lightweight essence works for all skin types. It uses snail mucin to add moisture to the skin and address fine lines without being sticky or heavy. “This is one of my hands-down holy grail skin care products,” says NBC Select associate SEO reporter Ashley Morris. “It helps to smooth out the texture on my face, makes my skin feel softer and more hydrated after using, and soothes and prevents irritation.” (Ed’s note: This product dropped to its Prime Day price for one day in late July, but because it’s 60% off and one of our favorite products, we think it’s a worthwhile deal.)

Laneige Lip Sleeping Mask

4.6-star average rating from 45,682 reviews on Amazon

Laneige makes some of our favorite lip products, including its lip balm and this lip mask. The expert-recommended lip mask uses oils, butters and antioxidants to moisturize, protect and nourish your lips overnight. “This leaves my lips feeling soft and smooth overnight,” says NBC Select updated editor Mili Godio. “It’s great for the wintertime since my lips get extremely chapped in the cold weather — this mask soothes any dry patches and irritation by morning.”

Crest 3D Whitestrips Professional Effects

4.6-star average rating from 89,017 reviews on Amazon

This at-home teeth whitening kit, which has the American Dental Association’s Seal of Acceptance, gently removes new and old stains using hydrogen peroxide, an enamel-safe ingredient. The strips can reduce stains in just two weeks, according to the brand. The pack comes with 18 treatments. (Ed’s note: This product cost $.91 less for one day in late August, but because it’s 50% off and one of our favorite products, we think it’s a worthwhile deal.)

Dyson Supersonic Hair Dryer

4.3-star average rating from 675 reviews on Amazon

Lowest price ever

Our experts recommend Dyson’s Supersonic hair dryer because it’s suitable for all hair types and helps prevent heat damage. The dryer has a self-regulating sensor that protects your hair while simultaneously reducing frizz and adding shine, according to the brand. It comes with five attachments: a diffuser, styling concentrator, flyaway attachment, gentle air attachment and a wide-tooth comb.

Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant

4.5-star average rating from 2,152 reviews on Amazon

Suitable for all skin types, this liquid exfoliant uses salicylic acid to unclog pores and reduce the appearance of fine lines, according to experts in our guide to the best exfoliating products. It has soothing green tea to support your skin barrier, according to the brand.

Embryolisse Lait-Crème Concentré

4.2-star average rating from 1,478 reviews on Amazon

This moisturizer is an NBC Select staff favorite for dry skin because it’s thick and creamy without feeling heavy or greasy. I love using it when I wear makeup because it doubles as a primer and has a smoothing effect that minimizes fine lines.

Waterpik Cordless Advanced 2.0 Water Flosser

4.3-star average rating from 62,750 reviews on Amazon

This ADA-accepted water flosser uses water pressure and pulsations to remove plaque while also maintaining and improving gum health, according to the brand. The portable device comes with four tips, three pressure settings and travel equipment so you can take your flosser on the go. The brand also recently released a water flosser and electric toothbrush combination, which is on sale now.

La Roche-Posay Toleraine Skin Care Set

4.6-star average rating from 34,547 reviews on Amazon

This cleanser and moisturizer duo hydrates your skin and removes any grime and oil from the day. NBC Select associate updates editor Zoe Malin uses the cream every morning because she loves how it’s lightweight, moisturizing, absorbs quickly and combats her skin care concerns, including dry, flakey skin. Both the cleanser and moisturizer are free of common irritants and are noncomedogenic, so that they won’t clog your pores.

Living Proof Perfect Hair Day (PhD) Dry Shampoo 

4.3-star average rating from 13,102 reviews on Amazon

Living Proof’s talc-free dry shampoo cleans hair and absorbs oil, sweat and odor using a blend of powders, including starch and odor neutralizers, according to the brand. “This dry shampoo absorbs any greasiness on my scalp and hair and gives me second-day hair even when it’s really the third or fourth day,” says Godio.

As a beauty writer for NBC Select, I try hundreds of products throughout the year and have written about the best body serums, shower oils and lotions for mature skin. All of my recommendations above are based on NBC Select’s previous coverage and reporting. I also included products the NBC Select staff tested, including Wellness Award winners. I ran each deal through price trackers like CamelCamelCamel to ensure products are at their lowest price in at least three months. All the products I recommend are highly rated with at least a 4.0-star average rating from hundreds of reviews.

I’m an associate reporter for NBC Select who has covered deals and sales for over a year. To round up the best discounts on beauty items during Prime Big Deal Days, I found highly rated products at their lowest price in at least three months.
