Amazon Reviewers Say These $28-and-Under Serums Seriously Improved Their Skin

Rating: 4.3/5 stars, 140,243 reviews on Amazon

Serums that combine vitamins C and E or are loaded with hyaluronic acid represent some of the most in-demand formulations on the market. (Almost every brand carries at least one iteration of each!) Therefore, it's no wonder this antioxidant-rich formulation from TruSkin is one of Amazon's most sought-after and highly-rated options. In fact, 68% of reviewers awarded it a score of five stars.

"The results are unbelievable," explains one satisfied reviewer. "I was a bit skeptical because many of the reviews were from Caucasian women, and I was slightly worried that my skin would not respond as well, but I was quite mistaken. With or without makeup, my skin is bright, smooth, and my spots are disappearing."

Retinol-enriched serums are a dime a dozen at every major beauty retailer, but they're especially plentiful on Amazon. That said, the fact that this $17 option from leading drugstore brand CeraVe speaks volumes to its efficacy despite its excitingly low price point. Expertly developed with dermatologists, this best-selling serum specifically targets discoloration and uneven skin texture, especially marks left behind from acne. It received a five-star rating from 76% of Amazon customers.

"I am in my 60s and have combination/acne-prone/large pores/hyperpigmentation skin," notes one Amazon shopper. "I like this product because I do believe it contributes to pore-refining and brightening. I can see the dark spots are definitely getting lighter, which makes me so happy. This is a well-priced, positive addition to my anti-aging skincare regime. I can really notice the difference on my neck where there is so much discoloration on the sides. I do think overall that it is helping, and I do not have any burning, itching, or redness, which is another plus."

Nope, that isn't a typo. This top-rated serum isn't one serum—it's three for the delightedly affordable price of $24. Designed for all skin types, this handy three-pack features a vitamin C serum to aid brightening, a retinol serum to help diminish lines and wrinkles, and a hyaluronic acid serum to boost hydration. The trio has five stars from 68% of Amazon customers.

Here's one reviewer's satisfied consensus: "At 68 years old, I can testify that I am an experienced skincare shopper, and I have purchased many expensive facial skin brands in addition to lesser-known 'all-natural' unknown brands online and inexpensive drugstore lines. I have never found a skincare brand like Tree of Life.

"Tree of Life serums deliver what they promise. My skin has never looked this beautiful since before I began my menopausal years. My pores are shrinking, and my wrinkles are gently smoothing out. My two daughters, who are young moms, have begun using Tree of Life products, and several of my 'mature' friends have begun using this line as well. I suggest beginning with this three-pack and going from there—you will notice a significant improvement within just a couple of weeks!"

If you're looking for a superstar face serum loaded with natural ingredients that can cover a multitude of skin goals (aging, dullness, and acne), this option from Eva Naturals might be one of your best bets. In addition to vitamin C, this top-rated bottle also houses retinol, hyaluronic acid, salicylic acid, MSM, and niacinamide. A whopping 72% of Amazon reviewers gave it five stars. 

"I purchased this product in April and have waited this long to write a review because I wanted to give it time to work," one honest reviewer explains. "I'm 38 and suffered from constant cystic acne. My pores clog easily, and I'm very oily. I am also bi-racial and scarred very easily. Since April, I think I've had three pimples (all period-related) that went away very quickly. That's a miracle. I put this product on at night after my shower and make sure it dries well. I'm still good on product and probably won't be reordering for another few weeks—I only use a small amount [each] day. I haven't been more pleased with something I bought on here or [from] ANY store since... well, never."

The name of this product isn't kidding—this serum is potent and actively laden with powerful acids to help reduce dark spots and stubborn hyperpigmentation. As many reviews point out, your skin will likely get worse before it gets better, and it's also imperative to moisturize (a lot) and be extra diligent with your SPF application while using this top-rated serum. In addition to salicylic acid, it also contains other extra-strength brighteners like azelaic acid, lactic acid, and vitamin C. After scouring reviews, customers of all skin types and tones seem to have positive results (when they've used the product as directed) and 57% of the 132 reviews dubbed it a five-star winner.

This glowing review says it all: "After learning the correct way to use this product, I will say my skin is looking so much better. My dark spots and even the dark circles around my eyes are tremendously lighter, and I can go outside without makeup without feeling insecure or ashamed of how my skin looks! It even minimizes pores. People keep complimenting my skin, and that has never happened! [I] love this product. I will make sure I keep this stocked, just in case!

As you can see, there's serious demand (and lots of love) for both vitamin C and hyaluronic acid serums on Amazon. This pick serum from CeraVe features both of the aforementioned ingredients, and is one of the best options if you're seeking instant gratification where brightening and hydration perks are concerned, according to savvy shoppers. Plus, 68% dubbed it worthy of five stars.

Here's one testament from a reviewer who says it works: "I have sensitive, dry, pale skin. My skin breaks out all the time, and the red marks never seem to fade. I wanted to try a vitamin C serum to see if it would help with redness. Holy moly, this stuff works! There's no strong fragrance, and the serum absorbs into the skin quickly, leaving no residue. I apply a light moisturizer over it before applying makeup in the morning. I have not even finished the entire tube, and I can already tell my skin is softer, and I have not had any breakouts. Old red spots are also fading. I know this isn't all in my head either... My boyfriend noticed and commented that my skin was looking better—totally unprompted. This dude doesn't even notice when I get a haircut, so I consider this a big deal."

If you're looking for one of the best pure hyaluronic acid serums on the Amazon market, the overwhelming number of positive reviews point to this bottle as a fantastic option for glowy hydration—70% of the thousands of reviews gave it five stars, and it gets bonus points for being natural and organic. (It's also vegan, cruelty-free, and paraben-free.)

"I was skeptical about purchasing this serum since I usually stick to specific brands I'm familiar with after lots of trial and error," shares one satisfied reviewer. "I came across this brand just from searching 'Hyaluronic Acid Serum' and began reading the reviews which spoke highly of this product. I purchased it and have been using it for four days now in conjunction with my micro-needling tool. THIS IS THE REAL DEAL! My face is hydrated, plump, and has a glow. I am very happy with this hyaluronic acid serum, and I highly recommend it to anyone who was in their "should I try this or not" stage. Also, I keep mine in the fridge, and I love the way it wakes up the  face in the morning."

Finding the best regimen for your specific skin concerns can be tricky, and not every serum or product is a great fit for all skin types. However, fortified with vitamin C, ferulic acid, hyaluronic acid, sea buckthorn oil, and plant stem cells, InstaNaturals' top-rated serum is specifically meant to play nicely with every skin type and to address and help treat a wide array of skin concerns. It has a very similar ingredient profile to holy-grail face serums which are five times the price! It has five stars from 71% of reviewers on Amazon.

"I have had deep acne scars for about 10 years and have tried every product out there trying to minimize their appearance," notes one customer. "I have been using this vitamin C serum on my face, and in two months, the scars have disappeared completely. I wish I had taken before pictures to really show what a difference it made, but it has been a miracle in my life, and I no longer need a 30-minute skincare routine (scrubbing, exfoliating, lotions, potions, etc.). I have extremely sensitive skin and eczema and have had no issues with this product. So happy!"

In addition to offering a surge of moisture (crucial during the upcoming summer months), this popular face serum is also oil-free, noncomedogenic, and beautifully gentle on even the most sensitive skin types. It's designed to lock in hydration in order to help you achieve maximum complexion benefits such as major smoothing and brightening perks. And 77% of Amazon reviewers think it's deserving of an impressive five-star rating. Dermatologists love it too. 

Need proof? Check out the following glowing review. "My dermatologist suggested I stop paying premium prices for 'high-end' skincare products and try Neutrogena instead. He was right—this serum has taken care of my dry skin and has balanced out the oily areas. It's not greasy at all. This serum is a great product."

Mad Hippie is one of our all-time favorite natural and organic skincare brands, and we're not surprised the brand's vitamin C serum has created such positive pandemonium among Amazon shoppers. The combination of ingredients is pure, good-skin dynamite and boasts the following all-star lineup: vitamin C (to boost collagen production and diminish wrinkles or discoloration), vitamin E (for antioxidant benefits and to prevent expedited signs of aging), ferulic acid (another antioxidant and skin-protecting powerhouse), and hyaluronic acid (to plump, hydrate, and boost glow). Amazon customers love it, and 77% of reviews scored it with a full five-star grade. In fact, this Amazon reviewer calls it "the best serum ever": 

"I've spent hundreds of dollars on products to lighten the dark spots on my face from acne scarring. This has been the only product that has not only lightened the dark spots but hasn't made me break out more! This is like liquid gold for me. I recommend this to anyone with sensitive skin who is looking to get rid of dark spots. I'm on my second bottle, and I get compliments all the time that my skin looks like it's glowing. Also, for the first time in forever, I leave the house with only a tinted CC cream on my face and feel confident that my skin looks good! I will be a customer for life!"

This shower gel from Bioderma is just as good as its micellar water. It's great for those with sensitive skin, is soap-free, and pairs perfectly with the brand's Hydrating Body Lotion ($21).

For a boost of SPF protection, this option from La Roche-Posay is it. The formula really melts into the skin like the name promises.

The first, and one of the most important, steps in giving yourself an at-home facial is to thoroughly cleanse your skin," beauty director of branded content Caitie Schlisserman explains. "I rotate between cleansers, but this has been my most recent pick. It works so well for acne-prone skin and helps heal and prevent breakouts without stripping your skin of all its moisture. It's made with organic green tea, which helps reduce redness; salicylic acid to suck all the dirt and grime from your pores; and blue-green algae, which acts as a natural retinol."

"I've never used such an affordable face mask that does such a good job of deep-cleaning my pores," Schlisserman shares. "It's unique because it comes in powder form, and you need to mix it with equal parts apple cider vinegar (or water, but I always do the vinegar), stir well, and apply a thin layer to your face. Leave it on for no more than 20 minutes, and wash it off with lukewarm water. I swear you'll notice a huge difference in your skin, especially if you start using it routinely. I do want to mention that you'll feel your skin tighten and tingle when you have it on, and your skin might be red afterward, but it usually goes away after 30 minutes."

As someone who's always trying to keep her blonde hair pristinely, well, blonde, I always have these handy treatments in my Amazon cart. The formula is an excellent dark-horse hair treatment that clarifies strands to nix brassiness and residue. It honestly even rivals Olaplex.

These spa-like clothes are practically currency within the celeb and makeup artist sets and make taking your makeup off less of a chore. I have about 20 packs stored under my sink at all times! 

Quite a few WWW staffers swear by these handy face shavers, and I'm constantly reminded that I need to add them to my next Amazon haul. I've heard they're the best for nixing any unwanted peach fuzz.

"I'm not too proud to admit that single-use hair treatments may feel a little excessive in the packaging department, but they sure do make for excellent portion control," says beauty writer Courtney Higgs. "Especially for those with thick and textured hair types, an individual portion like this is great for ensuring that you don't accidentally use half a jar of a *very* expensive treatment all at once. Keep these on deck for those instances where you want to treat yourself to a luxe deep conditioning."
