Curology is a skincare brand that's all about personalization. Consumers fill out a quiz on the brand's website describing their skincare goals and current skincare issues, and Curology suggests custom-formulated products.
But is personalized skincare backed by science, or is this just clever marketing? Do Curology's products contain research-backed ingredients for improving skin quality and appearance? Do they contain any questionable additives? And is Curology better or worse than other popular personalized skincare brands?
In this article we'll answer all of these questions and more, as we review clinical studies to share our thoughts on whether or not personalized skincare is legitimate.
We'll analyze the ingredients in three of Curology's best-selling products (Lip Balm, Moisturizer and Acne Cream) to give our take on whether or not they're likely to be effective, and whether or not they're healthy.
We'll also compare Curology to other popular personalized skincare brands in terms of formulation quality.
Key takeaways:
- We consider "individualized" cosmetics to be marketing rather than good science
- Curology's moisturizer is very effectively formulated
- We do not currently recommend Curology overall
Is Personalized Skincare Legit?
Personalized cosmetics are becoming increasingly popular (with brands like Function of Beauty even selling personalized shampoo), and it's not surprising from a marketing standpoint.
Curology's brand differentiation is centered on this type of personalization for topical serums:

We don't believe that someone seeking an anti-aging effect is likely to benefit from personalized skincare at this point in time, because most of the factors that negatively affect and age skin are consistent across skin types.
No matter what your skin type, UV damage will degrade your skin. No matter what your skin type, biological aging will degrade your skin.
There are well-studied compounds such as hyaluronic acid which are clinically shown to reduce the signs of aging when applied topically, and these are likely to be effective regardless of an individual's skin condition or age.
However, when it comes to treating specific skin disorders, individualized skincare can be useful. A patient diagnosed with rosacea will require a different set of active ingredients than a patient without any skin conditions.
But this type of individualized treatment already exists. If a patient goes to a dermatologist and gets diagnosed with a skin condition, they will receive recommendations for products which help to treat or manage that skin condition.
And we believe it would be a much better option to see a dermatologist and receive truly individualized advice based on testing than to receive personalized products from eCommerce companies based on online tests.
There are some cases where personalized skincare may benefit consumers without diagnosed skin conditions.
A medical review of the benefits and drawbacks of personalized skincare, published in the Clinical, Cosmetic and Investigational Dermatology journal, found that personalized skincare may optimize aging outcomes based on custom sunscreen formulations.
People have different levels of melanin in their skin, and may require different strengths of sun protection based on their melanin levels. Personalized skincare may optimize this process in a way that a standard sunscreen brand couldn't.
Overall, we believe that personalized skincare may provide some minor benefits, but at the current stage of clinical research we do not believe it will provide significant benefits or that it's worth an increased cost.
Moisturizer Ingredient Analysis
The ingredients in Curology Gel Moisturizer are shown below:

Glycerin was shown to hydrate the skin and support skin barrier repair in a medical review published in the British Journal of Dermatology.
Sorbitan olivate and cetearyl olivate may have synergistic effects in naturally hydrating the skin (meaning the combined effect of both is greater than the individual effect of either), according to a 2019 clinical trial.
Sodium hyaluronate is one of the most well-studied anti-aging ingredients, and is clinically shown to reduce the appearance of fine lines and wrinkles, as we documented in our Global Beauty Care review article.
Curology significantly improved the healthiness of this formulation since our initial analysis, removing two inactive ingredients we consider unhealthy.
Overall, we consider Curology The Moisturizer likely effective for skin moisturization and we recommend this product. It contains no ingredients that we consider to be unhealthy.
Curology vs. Popular Personalized Skincare
Here's how Curology compares to other popular personalized skincare brands in terms of formulation quality, in our opinion:
Agency Skincare
Agency Skincare is another personalized skincare brand that offers custom-formulated products based on individual skin assessments.
A 2025 clinical trial found that machine learning-enabled personalized skincare recommendations significantly reduced acne symptoms and improved quality of life, suggesting that AI-driven personalization may have clinical merit.
Agency Skincare's formulations are generally transparent about inactive ingredients, which gives them an advantage over Curology's custom products where the full inactive ingredient list is not easily accessible.
Winner: Agency Skincare
Proven Skincare
Proven Skincare uses an AI-powered approach to formulate personalized skincare regimens, as we documented in our Proven Skincare review article.
Proven's formulations use many of the same research-backed active ingredients as Curology, but the brand provides more transparency around its full ingredient lists for consumers to evaluate.
Winner: Proven Skincare
Function of Beauty
Function of Beauty offers personalized skincare and hair care products based on an online quiz, similar to Curology's approach.
Function of Beauty's skincare formulations are reasonably well-formulated, but share a similar limitation to Curology in that the full ingredient lists of customized products may not be easily accessible to consumers.
Winner: Curology
Lip Balm Ingredient Analysis
The ingredients in the Original flavor of Curology The Lip Balm are shown below:
image source: https://curology.com/
Jojoba seed oil and beeswax are natural emollients which should improve and prevent dry skin.
Hyaluronic acid is clinically shown to both reduce wrinkles and "rejuvenate" skin.
Phenoxyethanol is the only inactive ingredient in this formulation that we consider to be questionable from a health perspective.
As we documented in our VouPre review article, this preservative is clinically shown to be toxic to human cells, at least in a test tube study.
The scented versions of this lip balm contain fragrance and flavoring ingredients like d-limonene and flavor that we consider to be questionable from a health perspective, so for consumers set on purchasing Curology's lip balm, we recommend the Original formulation.
Overall, we consider Curology Original Lip Balm likely to moisturize the lips and somewhat likely to have an anti-aging effect, but we don't currently recommend this product due to the inclusion of phenoxyethanol.
Mind Body Green Lip Balm is our top healthy lip balm pick.
This product has the healthiest formulation of any lip balm we've reviewed. Like Curology's lip balm, it contains hydrating natural ingredients like sunflower seed oil and shea butter, but is free of phenoxyethanol.
Acne Cream Ingredient Analysis
The active ingredients in Curology Acne Cream are shown below:
image source: https://curology.com/
Curology's acne cream is custom-formulated, and the product page on the brand's website states that the formulation "can include niacinamide, azelaic acid, clindamycin."
Niacinamide is a form of vitamin B3 that has anti-inflammatory properties. While it may help manage mild acne and improve skin texture, it is not as potent an acne treatment as the tretinoin it replaced.
Azelaic acid is effective for treating acne, and may have secondary benefits to skin.
This compound is clinically shown to have an anti-aging effect, as we documented in our Agency Skincare review article.
Clindamycin is a topical antibiotic. It's effective against acne for short-term use, because acne is primarily bacterial in nature.
A medical review published in the Expert Opinion on Pharmacotherapy journal found that this ingredient was one of the most effective topical antibiotics, but that it had questionable long-term viability due to increasing bacterial resistance.
Overall, we consider Curology Acne Cream likely to be effective given that the brand uses research-backed active ingredients. Because this product is custom-formulated and we can't review the inactive ingredients, we don't currently recommend it.
Our Clean Skincare Pick
MindBodyGreen Best Skin+ is our top anti-aging skin supplement.
It contains orange extract which is clinically shown to increase skin moisturization, skin elasticity and skin radiance.
This supplement also contains astaxanthin which is clinically shown to cause "wrinkle formation reduction."
This supplement is free of ingredients that we consider to be unhealthy.
Curology Pros and Cons
Pros:
- Formulations contain many research-backed ingredients

Cons:
- Lip balm contains phenoxyethanol
- Inactive ingredients in custom formulations aren't easily accessible
