Flip over almost any skincare product and you'll find preservatives on the ingredient list. They're there for good reason — without them, your moisturizer or serum would grow mold and bacteria within days. But not all preservatives are created equal, and understanding the difference between natural and synthetic options is key to making informed choices about what you put on your skin.Why preservatives are non-negotiableAny product that contains water — which is most skincare — is a breeding ground for microbial growth. Bacteria, yeast, and mold thrive in aqueous environments, and without a preservative system in place, contamination can happen quickly. This isn't just a cosmetic concern: contaminated products can cause serious skin infections, especially around the eyes.So preservatives aren't the enemy. The question is which ones are doing the job — and at what cost to your skin and body.The synthetic preservatives to know aboutSynthetic preservatives have been the industry standard for decades because they're inexpensive, stable, and highly effective. But several have come under increasing scrutiny: Parabens (methylparaben, propylparaben, butylparaben): The most studied and most debated. Parabens are endocrine disruptors — they mimic estrogen in the body. While regulatory agencies consider low concentrations safe, many consumers and dermatologists prefer to avoid them entirely, particularly in leave-on products like lotions and creams. Formaldehyde-releasing preservatives (DMDM hydantoin, imidazolidinyl urea, quaternium-15): These compounds slowly release small amounts of formaldehyde to prevent microbial growth. Formaldehyde is a known carcinogen and a common cause of contact allergies — among the most flagged ingredients in clean beauty. Phenoxyethanol: This one deserves a longer look. Regulators like the EU have determined that phenoxyethanol is conditionally safe — meaning it's permitted in cosmetics at concentrations up to 1%. That conditional approval sounds reassuring until you consider what it actually means in practice. As a consumer, you have no way of knowing exactly how much is in a given product. You have no way of knowing how it interacts with every other ingredient in that formula, or in the other three, five, or ten products you apply alongside it. And "safe for most people at a regulated concentration" is not the same as "safe for all people, in all combinations, every day." For people with sensitive skin, developing immune systems, or conditions that affect barrier function, that uncertainty matters. Our position: conditionally safe isn't good enough when cleaner alternatives exist. Benzalkonium chloride: Common in eye drops and some cleansers, this preservative has been linked to irritation and disruption of the skin barrier with regular use. Natural preservatives: effective, but more nuancedThe rise of clean beauty has driven significant innovation in natural preservation systems. These tend to be gentler, but they require more careful formulation to remain effective: Vitamin E (tocopherol): An antioxidant that helps slow oxidation in oil-based products. Works well as a co-preservative but isn't strong enough on its own for water-containing formulas. Rosemary extract: Effective at extending the shelf life of oils and butters, but not a standalone preservative for water-based formulas. Radish root ferment filtrate: A newer natural preservative derived from the fermentation of radish roots. Effective against bacteria and yeast, and increasingly popular in certified natural and organic skincare. Leuconostoc ferment filtrate: Another fermentation-derived preservative with broad-spectrum antimicrobial activity. Gentle enough for sensitive skin formulas and gaining traction as a clean alternative. What to look for on the labelYou don't need to memorize every preservative to shop smarter. A few practical rules of thumb: Avoid products listing parabens, DMDM hydantoin, imidazolidinyl urea, quaternium-15, or phenoxyethanol — especially in leave-on products. Look for products preserved with vitamin E, ferment filtrates, or other naturally-derived systems. Check third-party certifications: USDA Organic, EWG Verified, and COSMOS Organic all restrict or prohibit synthetic preservatives including phenoxyethanol. Be cautious of "preservative-free" claims on water-containing products — without proper preservation, products carry their own microbial risks. The bottom line"Permitted" and "proven safe for everyone, every day, in every combination" are very different standards. Regulatory approval of an ingredient at a certain concentration tells you something — but it can't account for cumulative exposure across your full routine, individual skin sensitivities, or long-term daily use. That gap is exactly why we apply the precautionary principle when curating what we carry.At Swell Market, we look beyond what's technically allowed and ask what we'd actually want on our own skin.

We talk a lot about vitamins in skincare — vitamin C for brightness, vitamin E for moisture, vitamin A for cell turnover. But there's a quieter category of nutrients that your skin depends on just as much, and most of us aren't getting nearly enough of them: trace minerals. What are trace minerals? Trace minerals are naturally occurring elements that your body needs in very small amounts to function properly. Unlike macro minerals like calcium and magnesium — which your body requires in larger quantities — trace minerals like zinc, selenium, copper, silica, and manganese are needed only in tiny amounts. But don't let the word "trace" fool you: their impact on your health, and your skin, is anything but small. How trace minerals affect your skin Your skin is your body's largest organ, and it relies on a steady supply of trace minerals to stay healthy. Here's what some of the key ones do: Zinc helps regulate oil production, supports wound healing, and has well-documented anti-inflammatory properties — making it a key player for acne-prone skin. Selenium is a powerful antioxidant that protects skin cells from oxidative stress and UV-related damage. Copper plays a role in collagen and elastin synthesis, helping skin stay firm and resilient. Silica supports the structural integrity of connective tissue and contributes to skin elasticity. Manganese activates enzymes involved in collagen production and helps neutralize free radicals. Why most of us are deficient As we've covered before, modern farming practices have dramatically reduced the mineral content of our soil. Crops grown in depleted soil absorb fewer minerals, which means the food on your plate contains fewer minerals than it did a generation ago. Processed and packaged foods compound the problem further — stripping away what little mineral content remains. The result? A widespread, largely invisible deficiency that shows up in ways we often chalk up to other causes — dull skin, slower healing, increased sensitivity, and premature signs of aging. Topical vs. internal — does it matter how you get them? Both routes have value, but they work differently. Topical applications of minerals can deliver targeted benefits directly to the skin. But for lasting, systemic skin health, internal mineral intake matters most. Your skin is fed from the inside out — and a body that's mineral deficient shows it. That's why pairing a mineral-rich diet with high-quality supplementation — and clean topical skincare — gives you the most complete approach. What to look for When shopping for supplements or skincare products that support mineral health, look for: Full-spectrum or broad-spectrum trace mineral supplements derived from natural sources Topical products featuring bio-active minerals Whole food-based formulas with minimal processing to preserve mineral integrity Transparent labeling that lists mineral sources, not just generic "mineral blend" The bottom line Trace minerals are one of the most underrated pillars of skin health. They work quietly in the background — supporting collagen, fighting oxidative stress, regulating oil, and keeping your skin's barrier strong. Getting enough of them, both through your diet and your skincare, is one of the simplest and most overlooked upgrades you can make to your routine. At Swell Market, we seek out products that honor this kind of whole-body approach to skin health. Browse our collection to find trace mineral supplements and clean skincare formulas that work from the inside out.

If you've ever stood in the skincare aisle squinting at labels, you're not alone. "Fragrance-free" and "unscented" sound like they mean the same thing — but they're actually quite different, and understanding the distinction could be a game-changer for anyone with sensitive, reactive, or acne-prone skin. What does "fragrance-free" actually mean? A product labeled fragrance-free contains no added fragrance ingredients — neither synthetic nor natural. That includes obvious culprits like synthetic musk or artificial rose scent, but also essential oils, botanical extracts added purely for scent, and even some naturally-derived aroma compounds. For people with sensitive skin or conditions like eczema, rosacea, or contact dermatitis, fragrance is one of the most common irritants in skincare. Choosing truly fragrance-free products removes one of the biggest triggers from your routine. So what does "unscented" mean? Here's where it gets tricky. "Unscented" means the product has no noticeable smell — but that doesn't mean fragrance-free. In fact, many unscented products contain masking fragrances: synthetic scent compounds added specifically to neutralize the natural odor of other ingredients. In other words, "unscented" can still contain fragrance. It just smells like nothing. Why does this matter for your skin? Fragrance — whether synthetic or natural — is one of the top contact allergens in skincare. The American Academy of Dermatology lists it among the most common causes of allergic contact dermatitis. Even "natural" fragrances like lavender, citrus, and ylang-ylang can trigger reactions in sensitive skin. If your skin stings, flushes, or breaks out after using products labeled "unscented," hidden masking fragrances could be the culprit. How to shop smarter Here's what to look for when scanning an ingredient list: Avoid: Parfum, fragrance, and aroma.  Look for: Products with a short, transparent ingredient list where every ingredient serves a functional purpose. We're not against products having a scent, but we believe consumers should be able to decide for themselves -- and the best way to do that is to fully disclose what's in the product, instead of hiding behind proprietary formulas. For example, linalool, limonene, citronellol, geraniol, eugenol — these are common fragrance compounds and frequent allergens, but not everyone is sensitive to them. Trust verified labels: Certifications from organizations can give you confidence that "fragrance-free" is genuinely fragrance-free. The bottom line When it comes to skincare, "fragrance-free" is the gold standard for sensitive skin — not "unscented." Reading labels carefully and understanding what those terms actually mean puts you in control of what goes on your skin. At Swell Market, we curate products that prioritize transparency and clean formulations — because your skin deserves to know exactly what it's getting.

Understanding the Role of Aluminum in Deodorants Aluminum compounds are the functional backbone of antiperspirants. Their role is straightforward: reduce sweat. They do this by forming temporary gel-like plugs inside the sweat ducts, limiting the amount of moisture that reaches the skin’s surface. In many cases, this can reduce perspiration by up to 20–30%. What’s often overlooked is that aluminum exposure isn’t limited to personal care. It’s present in food, water, and even cookware. That broader exposure context matters when evaluating risk—but it also means deodorant alone isn’t the full picture. There’s been ongoing concern around aluminum and long-term health, particularly in relation to neurotoxicity and chronic disease. While some associations have been explored, the current consensus from organizations like the American Cancer Society and the U.S. Food and Drug Administration is that there is no consistent or conclusive evidence linking aluminum in antiperspirants to breast cancer. That said, “not proven harmful” doesn’t always mean “optimal,” especially when looking at cumulative exposure and biological interactions. How Aluminum Works in Antiperspirants Aluminum salts—most commonly aluminum chlorohydrate—are highly effective at reducing sweat because they physically alter how sweat glands function. When applied, they dissolve in moisture and form a plug within the duct, restricting output. These compounds are typically used at concentrations between 10% and 30%, which is relatively high compared to most cosmetic ingredients. That’s why antiperspirants tend to outperform deodorants in terms of dryness—they’re solving a different problem. Effectiveness can vary from person to person based on factors like sweat rate, skin pH, and microbiome. Application timing also matters. Using antiperspirants at night, when sweat production is lower, can improve efficacy. However, higher concentrations also increase the likelihood of irritation, particularly for those with sensitive skin. Health Considerations: What Actually Matters 1. Kidney Function and Aluminum Clearance One of the more established concerns with aluminum exposure relates to kidney function. Individuals with impaired kidney function may have difficulty eliminating aluminum efficiently, which can lead to accumulation in the body. For this reason, caution around aluminum-containing products is generally advised for those with advanced kidney disease. For otherwise healthy individuals, systemic absorption through the skin is considered low, but not zero. 2. Aluminum and Hormone Disruption A more nuanced area of discussion is aluminum’s potential role as an endocrine-active compound. Some research suggests aluminum can exhibit weak estrogen-like activity, meaning it may interact with estrogen receptors or influence estrogen signaling pathways. These types of compounds are sometimes referred to as metalloestrogens. From a biological standpoint, hormone signaling is tightly regulated. Even small disruptions—especially when chronic—can have downstream effects. Estrogen, in particular, plays a role in: Cell growth and differentiation Reproductive health Metabolic regulation Neurological function Disruption of endocrine signaling doesn’t necessarily mean immediate or obvious harm. The concern is more about long-term modulation of hormonal balance, especially when combined with other environmental exposures that may act similarly. It’s also important to note that the skin—particularly areas like the underarm—can be a site of repeated, long-term exposure. Current research does not definitively establish aluminum in antiperspirants as a clinically significant endocrine disruptor in humans. However, the mechanism is biologically plausible, and it remains an area of active study. Deodorants vs. Antiperspirants: A Clear Distinction This distinction matters. Antiperspirants: Reduce sweat using aluminum compounds Deodorants: Control odor without blocking sweat Odor itself isn’t caused by sweat—it’s the result of bacteria metabolizing sweat components. Deodorants target this process using antimicrobial agents, pH modulation, or odor-absorbing ingredients. For many people, the shift away from aluminum isn’t about eliminating sweat—it’s about working with the body instead of suppressing it. Aluminum-Free Alternatives: What to Expect The aluminum-free category has evolved significantly. Modern formulations use a combination of: Magnesium compounds (odor-neutralizing) Zinc derivatives (bacterial control) Cyclodextrins (odor encapsulation) Botanical extracts and essential oils At Swell Market, the focus is on formulations that prioritize functional performance without unnecessary exposure risks. That means ingredient transparency, thoughtful formulation, and avoiding known irritants where possible. That said, aluminum-free doesn’t automatically mean irritation-free. Ingredients like baking soda can be harsh for some users, so formulation balance is key. What the Science Actually Says The current body of research does not support a direct causal link between aluminum in antiperspirants and diseases like breast cancer or Alzheimer’s. However: Aluminum can accumulate in the body under certain conditions It has demonstrated biological activity, including potential endocrine interactions Total exposure (dietary + environmental + topical) is often overlooked Regulatory bodies continue to monitor aluminum exposure levels, and most agree that typical use in cosmetics falls within established safety thresholds. But safety thresholds are not the same as optimization. Final Takeaway Aluminum in antiperspirants is effective—there’s no debate there. The real question is whether it aligns with your long-term health strategy. If your priority is maximum sweat reduction, antiperspirants deliver. If your priority is minimizing cumulative exposure, supporting natural biological function, and avoiding potential endocrine interactions, aluminum-free deodorants are worth exploring. For us though, we'll remain cautious. “Not proven harmful” isn’t the same as proven safe, and that distinction matters. In a category built on daily, long-term use, we believe ingredients should meet a higher standard of certainty. If the data isn’t clear, we default to caution.
