40 Percent Off Shark, $12 Medicube, My Favorite Retinal for $11, and More Prime Day Beauty Sales

This Strategist reader — and staff — favorite made our list of top-saved products of the year (so far). The pads exfoliate skin and deep-clean pores with lactic and salicylic acids.

Another most-saved product this year. I traded in my prescription tretinoin for this cream with over-the-counter retinal, the strongest of the OTC retinoids, and maintained my results (smooth, more even-toned skin) without irritation and excessive flaking.

Speaking of K-beauty and retinal, you can get two of these eye serums for less than the price of one. Retinal liposomes and ginseng smooth and brighten delicate under-eye skin.

Medicube is also offering big savings on its Booster Pro X2 device. It offers seven modes in one for glow, pore care, definition, and more. Makeup artist Sir John told The Cut that uses it daily to help with skin-care absorption.

I tested the higher-strength version of this product in a story about spicules, a buzzy K-beauty ingredient that creates microscopic punctures in the skin, allowing active ingredients to get deeper into the skin. This is the intro-level dose and a good place to start with spicule skin care.

I file this one under “sunscreen I want to wear.” The SPF stick feels so nice on my skin, controls oil, and layers well under my makeup.

Get glass skin overnight with this K-beauty hydrogel mask. It plumps, tightens pores, and brightens skin while you sleep.

This a stock-up moment. Aquaphor Healing Ointment is a regular in our “Beauty Aisle” features because it is works for dry skin, lips, cuticles, and more.

This Best in Class face cleanser is beloved by experts, staffers, and readers alike for its ability to cleanse without leaving skin feeling stripped.

Save over $100 on this red-light mask. It has four wavelengths, takes just three minutes, and is designed to fit around the contours of your face without missing a spot.

Internet personality Blakely Thornton can’t live without this retinol cream because it’s effective and already affordable — now even more so.

A Strategist staff-favorite cleanser. At least seven of us are using this glycerin-infused cleanser that cleans and moisturizes at the same time.

In an article on snail mucin, nearly every dermatologist our writer spoke with recommended CosRx because of its skin-brightening and moisturizing benefits.

This vitamin C, E, and ferulic acid serum is a best seller with Strategist readers, so it is our duty to tell you when it’s on sale.

Writer Dominique Pariso was impressed by the at-home Hydrafacial-like tool when it first launched and was impressed. “With the average cost of a Hydrafacial running somewhere in the $150 to $300 range these days, the FacialPro Glow would absolutely save money in the long run.”

Pariso, who tests a lot of styling tools, says this is her favorite leave-in heat-protecting spray.

After researching infrared technology for hair tools, I’m a convert. The tech helps dry the hair strand more evenly — inside and out — instead of overheating the outside layer, leading to dryness and damage. This dryer over $70 cheaper right now.

I also learned this year that blow-dryer technologies are not one-size-fits-all. If you have puffy, coarse, frizz-prone hair, ionic dryers can greatly reduce frizz and leave hair smoother.

I borrowed this tool from my tween and was really impressed with the curls it created — and how easy it is to use.

Shampoo and conditioner (with a yummy vanilla scent) for $15.

This is the lowest price we’ve seen this year for the pro-quality ceramic flat iron.

This is one of the early Prime Day deals we wrote about but, but a savings of $100 is worth repeating.

Fun fact: I wore this foundation on my wedding day 19 years ago (Laura Geller herself applied it), and it’s still a favorite today.

My tweens and teens always have these balms on their wish lists because they’re shiny, hydrating, and come in sheer pretty colors.

Bobbi Brown complexion products always get the job done well. This easy-to-apply stick is hydrating, creaseproof, buildable, and very blendable.

Makeup artist Tim Quinn recently told us he stocks up on these lip liners from NYX, especially in these nude shades.

I’ve complimented a few friends on their lashes over the years, thinking they got lash extensions or were using a lash serum for growth. They revealed they were wearing this tubing mascara.
