16 popular skin-care products on sale now - and what skin concerns they're good for

Some Vitamin C serums go for $150 and up, but this one has garnered a loyal following for much less (you should also check out Maelove's $28 Glow Maker). It lightens dark spots, reduces fine lines, and improves clarity with a blend of nutrients designed to aid collagen production. It uses a blend of vitamin C, Botanical Hyaluronic Acid, Vitamin E and Aloe Vera, MSM, Witch Hazel, and organic Jojoba oil to nourish skin.

The Foreo Luna 2 is the facial cleansing brush multiple Insider Picks reporters recommend as the best option out there — and worth the added expense. The mini Luna version is a bit more economical but has the same technology that makes using the device so effective.

It's made from a gentle, antibacterial silicone that deep-cleans without creating micro-scratches on the skin's surface or allowing bacteria to breed on the device itself. T-Sonic pulsations help the silicone touch-points remove dead skin cells, unclog pores, and remove the day's residue. In independent clinical trials, it removed 99.5% of dirt and 98.5% of makeup residue.

Retinol is one of the old-school "classics" in skin care simply because if it works for you, it really works. This popular, relatively affordable moisturizer includes 2.5% active Retinol to combat breakouts, Hyaluronic Acid to restore hydration levels, and a protective blend of vitamin E and green tea. Altogether, it should reduce the appearance of wrinkles with a bump in collagen production, clear up acne, even out skin tone, and reduce hyperpigmentation.

Bio-Oil is a popular solution for stretch marks, dryness, hyperpigmentation, and uneven texture in the skin. It's non-greasy, hypoallergenic, and, according to Bio-Oil, the number one-selling scar and stretch mark product in 18 countries and the winner of 220+ skin-care awards. All I can say is that, from experience, it's a great tool to have in your arsenal — and one I find myself frequently buying while traveling to deal with any unexpected dryness and hyperpigmentation quickly and reliably.

Peter Thomas Roth is one of the skin-care brands Insider Picks reporters own multiple products from — because it's a reliably good line that's worth the splurge.

The brand's popular overnight resurfacing pads work like an intensive peeling facial treatment. They exfoliate the skin and help cells turn over and renew for more even tone and texture and to decrease fine lines. These pads are an acid-free retinol treatment that (instead of acid) rely on Glucosamine and a high performing form of vitamin C to even and brighten the skin.

We also recommend checking out Dr. Dennis Gross' Alpha Beta Peel Pads ($79); Insider Picks editor Sally Kaplan credits them with being the only thing that helped prevent and clear up cystic acne and uneven skin.

Charcoal bars are a great, no-fuss way to draw sebum from blackheads and grime from your pores. This gentle Black Soap bar was a 2017 Soko Glam Best of K-beauty award winner and works to deep-clean your pores without drying out your complexion (thanks in part to shea butter and licorice root extract).

The Ordinary has become a bit of a phenomenon in the cheap-but-really-good skin care subset. Its shorthand is "clinical formulations with integrity" — meaning clinical tech matched with a transparent pricing model.

This Vitamin C Suspension has 23% pure L-Ascorbic Acid (which remains stable thanks to the lack of water in the formula) for the evening out of your skin tone as well as dehydrated spheres of Hyaluronic Acid for visible surface smoothing. In the end, the skin should appear tighter and noticeably brighter. It's also vegan and free of oil, alcohol, silicone, gluten, and fragrance.

It's not technically on sale at Sephora, but it's $6 while the same size (marked as on sale) is going for $12.72 on Amazon.

Neutrogena's Hydro Boost Hydrating Hyaluronic Acid Serum gives skin a boost of hydration thanks to Hyaluronic Acid, which, if you haven't heard of it yet, is the compound used so often in moisturizing toners because it can absorb up to 1,000 times its own weight in water. With it, Neutrogena's toner works to create glowy, supple, smooth skin with a product that sinks in quickly and is both oil-free and non-comedogenic.

Squalane is one ingredient dermatologists will likely see in a product and nod to say, "yep, that's going to be hydrating" (Like one did when I asked her to critique my skin-care routine). The Ordinary's Squalane serum is built to be a standout hydrator and prevent any ongoing loss of hydration that makes skin lose its suppleness.

Murad is another well-loved line, likely because it was developed by a dermatologist. Its Age Reform Refreshing Cleanser is formulated as a non-drying, foaming cleanser that uses softening ingredients like cucumber extract, white ginger, and algae to soothe the skin and remove makeup and impurities. It's also free of phthalates.

The Bio-RTx cream is a silky, gel-like moisturizer that's good for dry skin without feeling thick or greasy. The patented formula works to mimic the skin's naturally-occurring lipids to balance moisture levels, and includes 5% Bio RTx, which is a specially designed complex that repairs skin damage and fortifies the skin barrier.

Murad's Ultimate Moisture is said to lock optimal moisture levels in the skin for up to eight hours. It's a light, rich moisturizer that uses a combination of avocado, sunflower and olive fruit oils, and shea butter to bump hydration and smoothness and Retinyl palmitate to even tone and texture. It's formulated without parabens, sulfates, or phthalates.

This deep-cleansing glacial clay will gently pull excess oils and impurities from the skin. Use it on your T-zone or all over if your skin is especially congested.

This clay detox mask is designed to suck up impurities from deep within the skin. Magnesium-rich amethyst clay should absorb the dirt and residue while respecting natural oils. The clay will detoxify and resurface the skin for smoothness, and ingredients like a stabilized vitamin C, Kakadu plum, and Tasmanian pepper berry should facilitate softer, brighter, more even skin post-use.

If you or someone you know is a Murad fan, this gift set covers the basics and is 20% off right now. You'll find the AHA/BHA Exfoliating Cleanser (one ounce.), Invisiblur Perfecting Shield Broad Spectrum SPF 30, Retinol Youth Renewal Serum, Hydro-Dynamic Ultimate Moisture, and Multi-Vitamin Infusion Oil.
