Are Circumference products cruelty-free?

We never test on animals. Our products are tested on humans only, and are obsessively formulated to ensure efficacy, safety, and stability.

We also refuse to use any ingredients that are known to be harmful to our environment, animals or people. Chemicals such as parabens, phtalates, BHAs, and BHTs, for example, are known to cause devastating effects for marine life when they enter our natural water systems. If we learn that something we’re currently using is harmful thanks to new scientific research or testing, we will immediately work to reformulate that product.

Are Circumference products all natural?

All of our products are naturally powered; the purity of nature is always our first stop and our go-to. But since some natural ingredients can degrade very quickly, we use a combination of natural, naturally derived, and non-harmful synthetics for maximum efficacy, safety, and stability.

Lastly, we never use parabens, phtalates, sulfates, BHAs, BHTs, synthetic fragrances, or toxic additives. These chemicals are widely known to be not just harmful to your health and your skin, but to our planet at scale. Your safety is our top concern—so anything that may even potentially hurt you or your (our) environment will never find its way into our products.

How do you source your ingredients?

We’ve gone through a long, rigorous process of vetting partners around the world to sustainably source botanicals that meet our sky-high standards, and this is the process that now informs all of our sourcing.

We work with our partners to ensure that our plants are always traced back to their native origins, as we believe (and science shows) that botanicals and its nutrients are in their purest, most effective state when sourced from their own indigenous regions.

We never use ingredients that are in danger of global shortage. We and our partners keep a close eye on worldwide production, yield, and supply of plants, so as to never exacerbate any global shortages.

We run through a rigorous state-of-the-art composition testing process called LC/MS-MS (liquid chromatography-mass spectrometry) to ensure the purity of each plant we extract. Our quest for sourcing the highest quality sustainable ingredients is never finished, and we can always do better. As we continue to develop new partnerships, we continue to reexamine our ways and evolve our process accordingly.

Where and how are your products made?

All Circumference products are dreamed up, designed, formulated, compounded, and bottled here in the US.

We never white-label our products—which is a common process across the industry, in which brands simply buy their formulations from labs, bottle them up, and slap their logo on them. Different companies selling the same exact product, often at wildly different (and higher) prices.

We begin each Circumference product formulation from scratch with our chemists. As we are highly involved in the development, testing and ingredient-sourcing process, our product-development process takes a minimum of 1 year.

When we develop our formulations, we obsess over the micro-details and go beyond overall ingredient percentages. Meaning: we analyze the individual compositions of each ingredient itself, so that every element works together within the product for optimal efficacy, safety and stability. Our formulations are meticulous and intentional, resulting in the highest-quality product possible.

Will your products fix all my skin problems?

We believe that no two humans are alike, especially in the way their skin reacts to new products. While Circumference products are formulated for all skin types and conditions, your skin may respond better to one over another. We would never make claims that any of our products are a cure-all for all skin issues, as we scientifically know that to be impossible. What we can promise, however, is that we use the absolute highest-quality ingredients, and formulate each and every product intentionally to deliver desired results. We believe that honesty is the best policy. If you’re not satisfied for whatever reason after using a Circumference product, you can review our return and exchange policy here, and don’t hesitate to contact us at

What is the shelf life of your products

Most of our products are tested to ensure safety and stability for up to 12 months. Just check the jar or bottle to view the product’s PAO.

Since we use mostly natural ingredients and don’t use heavy chemicals in our products, over time, you may notice some color change and separation in the product. Don’t be alarmed! Just give the product a shake before use to re-incorporate the ingredients, and you’re good to go.

The only exception to our standard 12-month shelf life is Vital-C Antioxidant Day Serum. While this product is rigorously tested for safety and stability for up to 12 months like the rest, our recommendation is that you use this serum within 6 months for maximum efficacy.
