Skin Care Reviews

09.28.18AD DISCLOSURE

When considering Korean skin care, COSRX is one of many brands that may be a viable solution for consumers in the United States. This Korean skin care company was founded on the idea of avoiding harmful ingredients and leveraging a number of botanical extracts to nourish the skin and reverse damage. Though such goals are commendable, it’s important to note that COSRX products may not be the right choice for everyone due to several key reasons. Firstly, some consumers may experience an allergic reaction to some of the botanical extracts. Secondly, with COSRX products being manufactured in Korea, the safety protocols may not meet the same guidelines as in the United States. Lastly, some consumers may have advanced skin concerns that simply won’t respond to over-the-counter treatments.

What are the Best Skin Care Products of 2020?

How COSRX Works

COSRX doesn’t adhere to a central philosophy. Instead, the manufacturer focuses on avoiding harmful ingredients and utilizing plant extracts for antioxidant and moisturizing benefits.

Further, the manufacturer doesn’t focus on any one skin concern. On the one hand, this may not seem very important. However, when a skin care company chooses to manufacture creams, cleansers and toners for many types of skin, it may find itself in a “jack of all trades, master of none” type of situation.

COSRX Ingredients

To avoid potentially serious side effects, it’s important to not simply rely on COSRX reviews, but to speak to a dermatologist and to assess the formulation ingredients. Let’s take a closer look at several select products.

  • Ultra-Moisturizing Lotion with Birch Sap:  The goal of this COSRX moisturizer is to hydrate the skin while exfoliating at the same time. Some of the ingredients include alpha and beta hydroxy acids, for skin exfoliation; lemon peel oil, for its vitamin C content; and tea tree oil, to promote skin healing. The cost of this COSRX moisturizer is roughly $19 for about 3.4 ounces.
  • Ultimate Nourishing Rice Overnight Spa Mask:  This COSRX face mask was formulated to brighten and moisturize the skin, and at about $18 for 1.7 ounces it’s quite affordable. Some of the ingredients include rice extract, to soften and moisturize the skin; sunflower seed oil, to hydrate; butylene glycol, for its skin conditioning properties; niacinamide, for its moisturizing and skin lightening properties; and glycerin, to hydrate and reinforce the moisture barrier.
  • Salicylic Acid Exfoliating Cleanser:  This cleanser from COSRX was developed to exfoliate the skin with one of the most popular beta hydroxy acids; salicylic acid. What makes salicylic acid so popular in skin care is its effectiveness at unclogging pores without causing significant irritation to the skin. These properties have made it especially popular for acne treatments. Other ingredients in this cleanser include tea tree oil, to promote skin healing; glycerin, to moisturize; and wintergreen leaf extract, for its skin conditioning properties. This COSRX cleanser is quite affordable, at around $12 for five ounces.
  • Hyaluronic Acid Hydra Power Essence:  The main ingredient in this COSRX essence is hyaluronic acid. The chemical is quite popular in the skin care industry due to its ability to hydrate. Some studies even suggest that hyaluronic acid can hold as much as 1,000 times its weight in moisture. Some of the other ingredients include glycerin, to moisturize the skin, and butylene glycol, for its conditioning effects.

Where to Buy COSRX Products

Consumers interested in where to buy COSRX products can find the items from a number of third party retailers. At this time, the company does not sell directly to the public in the United States.

Because of potential quality control issues when dealing with third party vendors, it’s vital to read COSRX reviews for the seller, to ensure that the products being sold are of high quality and not expired.

COSRX Side Effects

COSRX products are not believed to be the cause of serious side effects. However, some consumers may experience an allergic reaction to botanical extracts in the company’s products.

Further, exfoliating ingredients like alpha hydroxy acids and salicylic acid may cause temporary skin redness in users. Therefore, if using the products in the morning, it’s important to provide enough time for the redness to subside before leaving the house.

COSRX Reviews

Reviews for COSRX products are somewhat mixed. Although some consumers express great satisfaction, others suggest that the products are not very effective (of course, such feedback varies from one product to another).

However, the thing to remember about COSRX reviews (or other skin care reviews for that matter) is that most consumers fail to accurately describe their issue and current skin condition. For example, someone who is in their late 40’s will have wrinkles that are more severe and deeper than someone in their 20’s. Further, wrinkles and sagging skin in older individuals is also party affected by depletion of fatty tissues in the face.

Therefore, negative COSRX reviews may not be completely fair because there’s a limit to the improvements that can be achieved with any topical product, regardless of the brand.

THE BEST SKIN CARE LINES 2020

1

Formulyst

The philosophy of Formulyst is long-term and effective skincare, rather than covering up any imperfections. The comprehensive line of products tackles everything from wrinkles to dark spots and dry skin. While some brands rely on unnecessary fillers and scents, Formulyst focuses on ingredients that help create results, such as vitamins, minerals and antioxidants. Many of the Formulyst’s products harness the power of plant and citrus extracts as well as gold-standard workhorses such as retinol. Read More

The Advanced Dermatology skin care regimen addresses the most pressing aging concerns. It can be used by men and women in their 20s, 30s, 40s, 50s, 60s and beyond. This award-winning system can help diminish wrinkle appearance, reduce dark spots and hyperpigmentation, fade away redness, even out skin tone and improve the appearance of eye bags and dark circles. Some of the standout products in this line include the Super Youth Serum, Complete Age Defense and Anti-Wrinkle Firming Night Treatment. Read More

Cosrx Hyaluronic Acid Intensive Cream Review

COSRX Hyaluronic Acid Intensive Cream is a brightening face moisturizer that is said to deliver deep hydration all day long. This cream is formulated with key ingredients like Hippophae rhamnoides (sea buckthorn berry) water, panthenol, and sodium hyaluronate. Sea buckthorn berry water is known to improve the skin’s barrier function, as well as provide anti-inflammatory and antioxidant effects. Panthenol is the alcohol form of pantothenic acid, commonly known as vitamin B5, which functions as an effective humectant moisturizer. A humectant is a hygroscopic substance that has a molecular structure with several hydrophilic (water loving) groups. This structure allows panthenol to attract and retain the moisture in the air nearby via absorption, drawing the water vapor into or beneath the surface.

Sodium hyaluronate is the salt form of hyaluronic acid that has been shown to have better skin penetrating capabilities than hyaluronic acid alone. Similar to panthenol, sodium hyaluronate functions as a humectant by drawing moisture into the skin. Lastly, COSRX Hyaluronic Acid Intensive Cream contains emollients like caprylic/capric triglyceride, sunflower seed oil, and macadamia seed oil to help the skin feel soft and smooth.

Cosrx AHA 7 Whitehead Power Liquid Review

The Cosrx AHA 7 Whitehead Power Liquid was originally created to help specifcally target stubborn whiteheads. If you’ve struggled with these small breakouts before, you know how difficult they can be to treat. While there are dozens of products out there that cater to blackheads, very few options exist for targeting whiteheads specifically. This is exactly why CosRx developed this formula. Like all of the products from CosRx, the formula behind this product is minimal and active-ingredient focused. Instead of adding additional bells and whistles, the formulators have opted for a streamlined product that gets the job done, without overwhelming your skin, over exfoliating, or causing irritation. The core active within this formula is 7% glycolic acid. Glycolic acid is a powerful AHA or alpha hydroxy acid which works to exfoliate the surface of the skin, making it uniquely qualified to tackle surface level acne like whiteheads. What makes Glycolic acid unique is its very small molecule size, which allows it to go to work quickly in the skin. Glycolic acid is extremely powerful though, so we do recommend using this product a few times a week to start, so that your skin has a chance to get used to such a potent active.

COSRX Centella Blemish Cream Review

The CosRx Centella Blemish Cream was designed to serve as a hydrating and nourishing product that also served as a spot treatment for stubborn acne or the occasional breakout. Oftentimes, we see spot treatments that focus mainly on harsher ingredients like benzoyl peroxide in order to fight acne. But often, these intense formulations can lead to some discomfort or dryness afterwards, as well as more noticeable dry patches as the breakout begins to heal. This is where the CosRx Centella Blemish Cream differs quite a bit from the norm. Instead of drying out the pimple to speed up the healing process, the Centella Blemish Cream uses centella asiatica as the central active ingredient. Centella asiatica is an incredible skin soother. But how does that apply to acne? Centella asiatica works first and foremost to take down inflammation, which is what makes acne look so apparent, red and angry. From there, centella asiatica helps to rebalance the skin and speed up the healing process without sacrificing the skin’s moisture, which leads to less acne scarring as well as a speedy healing process.

COSRX Advanced Snail 92 All In One Cream Review

One of the most well known snail based products is without a doubt the CosRx Advanced Snail 92 All In One Cream. This product was designed to utilize all of the amazing benefits of snail mucin or snail secretion filtrate, alongside a slightly more occlusive base to form a nourishing, all-year moisturizer. Like most of the products from Cosrx, the emphasis within this formula falls on the active ingredient, while keeping the rest of the formula relatively minimal for ease of use. As the name would suggest, the Advanced Snail 92 All In One Cream contains 92% snail mucin, which can help with everything from fading signs of hyperpigmentation to calming redness and reducing the appearance of fine lines and wrinkles. Snail mucin got its claim to fame because of how effectively it produces results without compromising the health and balance of your skin. Because of this, snail mucin and products that contain snail mucin are extremely well suited to almost any skin type. With that said, because this is more of a cream based formula, we’d recommend this product in particular to those with more dry or dehydrated skin types.

COSRX AHA BHA Clarifying Treatment Toner Review

The CosRx AHA BHA Clarifying Treatment Toner was designed to serve as a seamless, gentle chemical exfoliant in a lightweight, spray on formulation. Like all of the products from CosRx, the formula behind this product highlights a few key active ingredients, but overall, keeps the ingredients list fairly minimal. As the name would suggest, the star of the show within this product is the AHAs and BHAs. Both of these are categorized as chemical exfoliants, but depending on which one you’re using, you can expect different results. For example, AHA’s or alpha hydroxy acids exfoliate the top layer of the skin to smooth out the surface and diminish the appearance of texture and hyperpigmentation. BHA’s or beta hydroxy acids are oil-soluble, which make them a great option for those who are struggling with things below the surface like blackheads, whiteheads and cystic acne. Together, this treatment offers the best of both worlds, making this product a great option for all skin types, especially those who are new to chemical exfoliants.

COSRX Low PH Good Morning Gel Cleanser Review

The Cosrx Low Ph Good Morning Gel Cleanser is easily one of the most iconic products from cult favorite K-beauty brand Cosrx. Cosrx has made a huge global impact and was one of the first brands to use the principles of K-beauty to formulate products for a global market. Because of this, all of their products focus on simplicity, using only what is needed, and catering towards hydration and care rather than stripping the skin with too many actives. The Low pH Good Morning Gel Cleanser is exactly how it sounds: an energizing, purifying cleanser with a gel-like texture that has been formulated at a pH of 5. Although this isn’t mentioned as frequently, the pH of your skincare products is actually crucial in terms of formulation, as well as the amount of benefit it leaves on the skin. For example, a cleanser with a higher pH can often feel more stripping and drying on the skin, which can result in irritation in the long run. With a lower pH however, this product is able to remove dry, grime and oil from your skin without stripping it of its natural moisture.

Cosrx BHA Blackhead Power Liquid Review

Cosrx BHA Blackhead Power Liquid is an anti-acne serum that is said to help reduce blackheads and excess sebum (oil). The beta hydroxy acid (BHA) effects provided by this serum come from Salix Alba (willow) bark water, which contains a compound called salicin. Salicylic acid, a common BHA used in skin care products, is derived from salicin. Salicin provides exceptional anti-inflammatory properties and has been shown to reduce the appearance of pores and wrinkles, as well as even out skin tone while increasing skin firmness.

Another key ingredient in the Cosrx BHA Blackhead Power Liquid is betaine salicylate, a combination of the moisturizing ingredient betaine and salicylic acid. Betaine salicylate functions as a mild exfoliant that works by softening and dissolving keratin, a protein found in the skin that acts as a “glue” to keep cells together. It also penetrates deep into pores to loosen clogs and allow oil to flow out more freely. Thus, betaine salicylate helps break down blackheads and whiteheads, while also moisturizing the skin. There are several other beneficial ingredients in the Cosrx BHA Blackhead Power Liquid, such as niacinamide, panthenol, and sodium hyaluronate.

Cosrx Advanced Snail 96 Mucin Power Essence Review

Have you ever thought about putting snail mucus on your face? While it may sound a little weird, this ingredient can actually be hugely beneficial to the skin. The Cosrx Advanced Snail 96 Mucin Power Essence is probably one of the most well known snail secretion products on the market, and for good reason. This product contains a whipping 96% snail secretion filtrate, making this one of the most concentrated formulas available. This heavy dosage of snail mucin helps to repair and hydrate the skin in a very gentle way, which is why it’s become so popular, especially in K-beauty. Snail mucin as an ingredient is most well known for its repairative properties, and because of this, has been used to treat just about any skin condition you can imagine. This includes dryness, skin sensitivity, acne, hyperpigmentation and even signs of aging. While this ingredient isn’t nearly as fast acting as actives like retinol or exfoliating acids, if you’re looking for a reparative, staple product to add to your routine, this is an excellent option.
