Antioxidant skincare products use ingredients like vitamin C, vitamin E, resveratrol, and green tea to neutralize free radicals — unstable molecules generated by UV exposure, pollution, temperature swings, and stress. Left unchecked, free radicals break down collagen, trigger inflammation, and accelerate visible aging. Antioxidants interrupt that process at the cellular level, supporting your skin's own repair mechanisms rather than overriding them. Every product in the Stark line is formulated around antioxidant-rich botanicals, which is why we consider them foundational to any routine — not a bonus step.

An antioxidant serum delivers a concentrated dose of protective and restorative ingredients directly to your skin. Because serums are formulated with smaller molecules than moisturizers, they penetrate more effectively and get active ingredients where they're needed most. Our CITY Brightening Serum uses a stable form of vitamin C (tetra-hexadecyl ascorbate) that brightens gradually without the irritation or pH conflicts of L-ascorbic acid. PETRICHOR Antioxidant Serum Mist combines vitamins C and E with resveratrol and green tea for layered environmental defense. The right one for you depends on whether your priority is brightening and tone (CITY) or hydration and protection (PETRICHOR).

A cleansing balm starts as a solid or semi-solid and melts into an oil as you massage it into skin, dissolving sunscreen, makeup, and daily buildup without stripping your moisture barrier. A gel or cream facial cleanser uses water-based surfactants to lift impurities and is typically better for oilier skin types or as a second cleanse. At Stark, AURORA is our cleansing balm — it transitions from balm to oil to a milky emulsion and rinses clean. ECLIPSE is our enzyme facial cleanser, using papaya and pineapple enzymes for gentle exfoliation instead of harsh acids. Many people use both: Aurora in the evening to remove the day, Eclipse in the morning or as a deeper second cleanse a few times a week.

A barrier cream (or barrier balm) is a product designed to reinforce your skin's acid mantle — the outermost protective layer that keeps moisture in and irritants out. You'd reach for one when your skin feels tight, reactive, or raw, which often happens during seasonal transitions, after over-exfoliating, or in extreme cold. Our SOLSTICE Ceramide Barrier Balm Serum is formulated with ceramides, mushroom extract, and sea buckthorn specifically for this job. It's concentrated enough to use as an overnight treatment on harsh winter nights — a thin layer over your regular routine acts as intensive barrier repair while you sleep.

Yes. Most vitamin C irritation comes from L-ascorbic acid, which requires a low pH to be effective and can sting, flush, or destabilize alongside other actives. Our CITY Brightening Serum uses tetra-hexadecyl ascorbate instead — an oil-soluble, stable form of vitamin C that doesn't depend on low pH, so it plays well with every other product in your routine. It absorbs quickly, layers under sunscreen without pilling, and delivers gradual brightening with consistent use. If your skin has rejected vitamin C serums before, this is worth trying — the delivery mechanism is fundamentally different from what probably irritated you.

Cold air and indoor heating strip moisture from your skin faster than most routines can replace it. The key is adding hydration and barrier protection without overcomplicating things. In winter, we recommend layering EQUINOX Calm + Smooth Serum (humectants like sodium PCA, glycerin, and sea kelp bioferment for deep hydration) under MIDNIGHT Resiliency Boost Oil Serum (omega-7 fatty acids, ceramides, and rosehip for overnight repair). On particularly harsh nights, add SOLSTICE Barrier Balm over top as an occlusive seal. For cleansing, favor AURORA over ECLIPSE in colder months — balm cleansers preserve your moisture barrier where gel cleansers can feel stripping when the air is dry.

Enzyme cleansers use fruit-derived proteins — typically from papaya, pineapple, or in Eclipse's case bilberry, sugar cane, orange, lemon, and sugar maple — to dissolve the bonds holding dead skin cells together. Unlike physical scrubs that remove cells through friction, or strong acids that work at a very low pH, enzyme exfoliation is biochemical and selective — it breaks down only dead cell proteins, leaving healthy skin cells untouched. The result is smoother, brighter skin without irritation or barrier disruption.

Every Stark product is formulated and hand-poured by our founder, Jess, in the Ottawa Valley of Canada. We've been making skincare this way since 2011 — small batches, botanical ingredients, no outsourced manufacturing. When you buy from Stark, you're not paying for corporate overhead, massive ad budgets, or shareholder returns. You're paying for 15 years of formulation expertise and ingredients that are chosen because they work, not because they're trending. We ship from Canada to both Canadian and US customers with flat-rate $10 shipping (free over $125) and zero customs fees or tariffs.
