The Most Effective Skin Serums, According To Reviewers And Dermatologists

SkinCeuticals C E ferulic acid, iS Clinical SuperSerum, Paula's Choice azelaic acid booster and Sunday Riley Good Genes serum

I am absolutely devoted to this powerful vitamin C serum. My esthetician recommended adding iS Clinical’s Super Serum to my lineup, and now I can’t imagine my skin without it. It's an oil-based vitamin C-rich serum that not only has the potential to help reduce typical signs of aging like fine lines, wrinkles and sun damage, but can help to reduce scarring as well. While it costs a pretty penny, I think it’s absolutely worth it. Not only are the quality and the results unbeatable, but a little goes a long way, making it less of a financial burden than one might imagine. It’s definitely worth the splurge.

Promising review: "Love this stuff. It might be a tad expensive, but it has done wonders for my skin to even it out and make it so smooth. Lines seem to have almost vanished (I’m 57). I have sensitive skin and this was not harsh, nor did it break out my skin. VERY happy with this product and would recommend this to anyone with sensitive skin who wants their skin to feel soft and look radiant. I get SO many compliments on my skin. Have been using for 5 months and will continue to do so.” — Kindle Customer

I've been using Sunday Riley's Good Genes for nearly a decade, and despite testing hundreds of other comparable products, I always come back to it. I’m particularly obsessed with the high content of lactic acid, a unique chemical exfoliant that encourages quick cell turnover in the surface layers of the skin, leaving it smoother and helping clear up blemishes. It’s paired with licorice and lemongrass in this formula, which can help brighten up the look of dark spots, sun damage and other discoloration, and prickly pear extract that can help soothe redness and calm sensitive skin. It's the perfect example of a product with a fairly common active ingredient that is perfectly formulated with other complementary ingredients to make it even more effective than many other options. 

Promising review: "Hands down the best skin product I've ever used. Worth the price. I don't write reviews on amazon but if I can help anyone justify the price given the magic it's done to my skin - worth the time! My 35 year old skin looks at least 10 years younger. I will buy this for life. (I could care less about the smell and honestly, don't really smell it? weird?)" — Patricia Izquierdo

Dr. Adeline Kikam, a board-certified dermatologist who shares advice on @brownskinderm, is a huge fan of this particular azelaic acid serum. She told HuffPost that "it is gently formulated with azelaic acid at 10% and allantoin at .3% for extra moisture." It can help soothe and calm irritated skin and help to reduce the appearance of redness. It's also formulated with micro-fine green color particles that can help to mask the look of existing redness as well, acting almost like a color corrector.

Promising review: "Helped my rosacea and PD. I bought this 3 days ago and am actually super surprised and impressed with this product. I’ve used azelaic acid before but found it irritating and heavy silicones in those formulas broke me out. I struggle with perioral dermatitis and rosacea. I was going through a pretty bad flare 3 days ago and as of today it’s 90% gone. I have some tips for how to best use the product: 1. Apply to dry skin only. Applying azelaic acid to wet or damp skin makes it super itchy and can cause irritation. ... I’m super impressed. This really helped clear up my latest flare and I’m excited to have found something that finally works for me. I’ll continue using and buying this as long as these results continue!" — Becca

Promising review: "If I had to choose to reduce my skin care routine to one product and feel confident that my skin will get all the nutrients it needs, it would be the Active Botanical.

Mandelic acid is a game-changer for acne-prone skin like mine, and The Ordinary makes it easy to pick up a high concentration of this anti-bacterial AHA exfoliant without breaking the bank. It's recommended for sensitive skin by two board-certified dermatologists, Dr. Purvisha Patel in Memphis, Tennessee, and Dr. Jennifer MacGregor of UnionDerm in New York City. The addition of hyaluronic acid brings skin extra hydration, making this a great formula for introducing your skin to mandelic acid. It's ideal for acne-prone skin, reducing the look of fine lines and chemical exfoliation.

Promising review: "Skin type: 30s, cystic acne prone, hyperpigmentation, redness, combination skin, CANNOT use salicylic acid, glycolic or lactic acid. I never thought I had sensitive skin until a product with salicylic acid broke me really badly a month before my wedding. Curse you, salicylic acid, you are not for me. But this product is - mandelic acid. I can't remember how I heard about it, but what really got me interested was the fact that's is recommended for Skin of Colour, like mine :D FIRST USE: I applied four drops on my face (forehead, cheeks, nose/chin) after cleansing (oil and foam), then allowed it to sink in before continuing with the rest of my routine (toner, serum, moisturiser). Honestly, it takes a little while to sink in your skin, don't use too much, you'll be waiting a LONG time. The next morning I was washing my face and I was like, omg, my cheeks are baby soft. So soft, my skin was legit renewed, it felt like a miracle was happening. Basically, any sort of decongestion was dissolved and I was left with smooth skin. Yes, it works, if you need an acid that won't irritate your skin, this may be the one for you." — PS

You can buy the mandelic acid 10% + HA from Sephora for around $8. 

HuffPost shopping writer and beauty devotee Tessa Flores swears by Sunday Riley's A+ retinoid serum, and she's not alone. It's a great way to introduce a powerful active ingredient into your routine. And while it's definitely an investment, a little goes a long way. The results also speak for themselves, making it worth every penny. 

Promising review: "Sunday Riley’s A+ retinol serum initially caught my eye because it was advertised as an advanced strength retinoid that was suitable for both individuals with sensitive skin and experienced users of the ingredient that might be in search of a stronger product. The formulation contains a 6.5% retinoid blend, a relatively high percentage compared with other retinol products on the market. After using this product consistently for two months, I’m noticing a significant reduction of my keratosis pilaris in that the texture is smoother, less red and with fewer clogged hair follicles. I’ve also noticed less congestion in my T-zone, fewer sun freckles and an overall increase in skin plumpness — all without those telltale signs of retinol-induced irritation." — Tessa Flores, shopping writer

You can buy the Sunday Riley A+ high dose retinoid serum from Amazon for $85. 

If you're into skin care, you've likely heard people sing the praises of this cult-favorite serum, and with good reason. The SkinCeuticals C E Ferulic serum has been praised by dermatologists for its ability to help lighten fine lines, firm skin, provide environmental protection and brighten a dull complexion. The stabilized formulation means all ingredients are working at the peak of their powers, in tandem with each other. 

Promising reviews: "I have tried many vitamin c serums and keep coming back to this one. It’s been highly effective on my skin, and while it’s pricey the results have been well worth it. One thing I have especially noticed is that it helps fade my acne scars pretty quickly." — GG

"When I first bought this, I was so apprehensive because of the price. But it really is amazing! You have to use it consistently for a few weeks to see the results, but it’s worth it. My skin has never looked better. A little goes a long way, so the price is worth it." — Emma

Promising review: "Gentle yet effective. Great for those with sensitive skin looking to clear out your pores. I have really sensitive skin. I can no longer use Salicylic Acid. This is what i use now.

I happen to be obsessed with using Luna oil in conjunction with Sunday Riley's Good Genes; it's a powerful duo that leaves me swimming in compliments and glowing skin. If you’ve been on the fence about trying an oil or retinoid, then this is the perfect place to start. Soothing botanicals like blue tansy and German chamomile are paired with an advanced retinoid ester that supports skin health and elasticity, evens out redness and fights fine lines and wrinkles. Avocado seed oil plumps up the skin and delivers a healthy dose of antioxidants. It doesn’t clog pores, which is perfect if you are acne-prone like myself.

Promising review: "I’ve been skeptical of Sunday Riley since their review debacle. I use other high-end skincare and wasn’t looking to add anything but this came highly suggested from a friend I trust. Now I can’t go a night without this beauty! The natural scents of chamomile are so relaxing and great part of self care to any nighttime routine to tell your nervous system 'it’s time for sleep.' It’s a very soft texture in the skin that feels nourishing and I love the deep blue tansy color that easily fades into skin as you apply. It’s a gentle retinoid that doesn’t irritate or interact with my other skincare. Overall my skin always looks bright and even in the morning. Love love this product, bought another for my mom for Mother’s Day! Can’t go wrong with adding this to a luxurious nighttime routine!" — shelby k

Promising reviews: "I have noticed a visible reduction in my fine lines since using this product. It also doesn’t leave my face oily or sticky like other serums can and do. I also really love that it has clean ingredients and does not have hardly any fragrance at all for those who are sensitive to fragrances like myself." — Daniii89

"Loved it! Excellent product !!! I've been using it since I bought it and I can see the difference in my skin. Highly recommended." — Kary9103
