Farm Stay Baking Powder Hyaluronic Acid Pore Scrub single-use sachets
Strong choice for Blackheads
What makes this different

It's the hyaluronic-acid take on Farm Stay's single-use baking-soda pore scrub — the same 40% baking soda, physical grit, and AHA/BHA exfoliating base as the collagen version, but with sodium hyaluronate swapped in as the hydration buffer, for those who prefer a humectant over a conditioning collagen finish.

Farm Stay Baking Powder Hyaluronic Acid Pore Scrub Review

Single-Use Pore Scrub Exfoliants powder k beauty Paraben free Not cruelty free

The hyaluronic-acid sibling of Farm Stay's single-use baking-soda pore scrub: the same fizzy, effective, genuinely abrasive 40% baking soda base, with sodium hyaluronate swapped in to ease the stripped feel. It polishes oily skin satisfyingly and cheaply, but the high-pH formula, grit, and menthol mean it's still an occasional-use-only treatment for resilient skin.

How well it fits each concern

Sold widely across global K-beauty retailers with a steady review presence, these scrubs are assessed here on the disclosed formula — high baking soda plus physical and chemical exfoliants with added hyaluronic acid — and the well-understood concerns of high-pH scrubs rather than a deep clinical record. Pricing and counts vary by retailer, so confirm current specifics where you buy.

Review

The full review

When a brand sells two nearly identical products, the useful review question is narrow: what actually differs, and does it matter? Farm Stay's Baking Powder Pore Scrub comes in a Collagen version and this Hyaluronic Acid version, and a side-by-side of the ingredient lists makes the answer plain. The exfoliating base is identical down to the percentages — 40% sodium bicarbonate, the same silica-and-cellulose grit, the same lactic/lactobionic/salicylic acid blend, the same centella, tea tree, and menthol. The single meaningful swap is the conditioning agent: sodium hyaluronate here, hydrolyzed collagen there. Everything else this scrub does, and every caution it carries, is shared with its sibling.

So let's deal with the difference first, briefly, because it's the only thing that distinguishes them. Hyaluronic acid is a humectant — it binds water — whereas the collagen in the other version acts as a film-forming conditioning agent. In practice, both are present at the same modest 1,000ppm and both serve the same purpose: to leave skin feeling a little less stripped after an inherently stripping scrub. The hyaluronic version may feel marginally more 'hydrated' and the collagen version marginally more 'cushioned,' but honestly, the difference is subtle and largely a matter of preference. Neither meaningfully changes how abrasive the underlying scrub is. If you're choosing between them, pick whichever conditioning agent you prefer in principle; you won't notice a dramatic gap.

Now the shared substance, which is what really matters. As an exfoliant, this works and works satisfyingly: mixed with water it forms a fizzy, gritty paste, and between the baking soda's alkaline action and the physical silica-and-cellulose particles, it lifts surface oil and dead skin effectively, leaving skin smooth, polished, and de-greased with a cooling mint tingle. The small AHA/BHA blend adds light pore-clarifying support, and centella and tea tree bring a touch of soothing and blemish-fighting. For oily, congested skin, the instant payoff is genuinely gratifying.

And the shared caution is equally important: this is not a gentle product, and the hyaluronic acid doesn't make it one. That's the myth to retire — the presence of HA on the label implies hydration and gentleness, but 40% baking soda at roughly pH 9, well above skin's acidic norm, plus physical grit and menthol, adds up to an abrasive, barrier-challenging scrub. The hyaluronic acid softens the aftermath; it does not make frequent use safe. Used too often or on the wrong skin, this can strip the acid mantle, compromise the barrier, and trigger the rebound oiliness and irritation that over-exfoliation causes. The squeaky-clean feeling it leaves is partly your barrier being stripped.

The usage rules are therefore the same as for the collagen version and non-negotiable: once or twice a week at most, gentle pressure, always followed by hydrating and soothing steps, and never on broken, irritated, dry, sensitive, or rosacea-prone skin. The single-use sachet format helps by dosing each use and making over-use slightly inconvenient — mix one with water, massage lightly over the oily T-zone and nose, rinse, done. A 25-sachet box lasts a few months at a sensible cadence.

Value is good in raw terms — 25 single-use treatments cheaply — but, as with its sibling, conditional on fit. It's only a bargain if your skin tolerates an abrasive high-pH scrub and you respect the frequency limit. For dry or sensitive skin, it's no deal at any price. And as a general matter, a low-pH leave-on chemical exfoliant is a gentler, more controllable way to clarify pores than a baking-soda scrub; this is the fun, tactile, occasional option rather than the optimal one.

Where it lands is exactly where the collagen version does: an effective, enjoyable, genuinely abrasive occasional scrub for resilient oily skin, with the hyaluronic acid a minor, preference-driven tweak. Buy whichever conditioning version appeals, use it sparingly and correctly, and don't mistake 'hyaluronic acid' on the front for gentleness.

Who should buy it? Oily, combination, resilient skin that enjoys an occasional deep-polishing scrub and prefers a hyaluronic-acid finish over collagen — and will keep to once or twice a week. Who should skip it? Dry, sensitive, rosacea-prone, or barrier-compromised skin, chronic over-exfoliators, and anyone who'd be better served by a gentler leave-on acid. As a single-use budget pore scrub, it's a fine, fun pick within firm guardrails. The honest bottom line matches its collagen twin: a fun, effective, genuinely abrasive scrub that rewards discipline and punishes overuse. The hyaluronic acid is a welcome comfort buffer, but it's the supporting detail, not a transformation of the formula's character. Keep it to once or twice a week on oily, resilient skin, always follow with hydrating and soothing steps, and skip it entirely if your skin runs dry, sensitive, or reactive. Within those guardrails it's a cheap, satisfying occasional deep-polish; outside them it's a barrier hazard. As with so much of this brand's lineup, the value is real — but only if the product actually matches your skin and you use it the way it's meant to be used.

The science

Functionally this is the same exfoliant as the collagen version, with hyaluronic acid substituted for collagen as the humectant. Sodium bicarbonate at 400,000ppm (40%) drives alkaline, mildly abrasive cleansing, but its pH of roughly 9 sits far above skin's acidic surface pH (~4.7–5.5), so repeated use risks disrupting the acid mantle and barrier — the central concern with any high-baking-soda product. Physical particles (silica, microcrystalline cellulose) add manual exfoliation with micro-abrasion potential under aggressive use. The AHA/PHA/BHA blend (lactic, lactobionic, salicylic acids) offers limited pore-clarifying benefit given brief rinse-off contact and the alkaline environment that is suboptimal for acid activity. Sodium hyaluronate (1,000ppm) is a humectant that binds water to reduce the post-wash tight feeling, but at that level and contact time it cannot offset the formula's fundamental abrasiveness — it eases the aftermath rather than changing the mechanism. Centella provides light soothing, and menthol adds a cooling but mildly irritating sensation. The honest scientific read is an effective but genuinely abrasive, high-pH exfoliant whose hyaluronic acid is a comfort buffer, not a gentleness conversion; occasional use on resilient oily skin only.

The clinical view

As with the collagen version, dermatology commentary is cautious about baking-soda scrubs, since sodium bicarbonate's high alkalinity conflicts with skin's acidic pH and can impair the barrier with repeated use, and physical scrubs risk micro-abrasion and over-exfoliation. The added hyaluronic acid is a reasonable humectant buffer but does not alter these fundamentals. For oily, resilient skin used sparingly, an occasional scrub can provide a satisfying deep-clean, but low-pH leave-on chemical exfoliants are generally preferred as gentler, more controllable alternatives. Menthol and fragrance add irritation potential. Dry, sensitive, rosacea-prone, or compromised skin should avoid this category, and all users are advised to limit frequency and rehydrate diligently afterward.

Formula

Key ingredients

  1. Sodium Bicarbonate (Baking Soda, 400,000ppm) 40%

    The 'baking powder' centerpiece at a high 40% — sodium bicarbonate provides the fizzy, alkaline, mildly abrasive cleansing that physically lifts surface oil and debris from pores, the same exfoliating engine as the collagen version.

    Not yet assessed
  2. Physical Exfoliant Beads (Silica & Cellulose)

    Silica and cellulose particles add gentle manual exfoliation, sweeping away dead skin alongside the baking soda for the immediate smooth, polished finish.

    Not yet assessed
  3. AHA/BHA Acid Blend (Lactic, Lactobionic, Salicylic)

    A small chemical-exfoliant blend of lactic and lactobionic AHAs plus salicylic BHA adds light pore-clarifying and smoothing action, though its effect is mild in a brief rinse-off scrub.

  4. Sodium Hyaluronate (1,000ppm)

    The version's defining swap — hyaluronic acid replaces the collagen of the sibling scrub as a humectant meant to bind water and leave skin feeling less stripped after the abrasive, alkaline exfoliation.

Layering

Treat it as an occasional exfoliating wash, not a daily one — empty a sachet, mix with water into a paste, massage gently over damp skin focusing on the T-zone and nose, then rinse. Follow with hydrating toner and moisturizer. Limit to 1-2 times a week to avoid over-exfoliation; avoid on broken or irritated skin.

When to expect results

Immediate: smoother, polished, less congested skin with a fresh, tingly feel. Ongoing: clearer-looking pores with occasional use as part of a balanced routine.

How to use it, and who it's for

How to use

Reach for it only once or twice a week, never daily. Empty a sachet, mix with a little water into a paste, and massage gently over damp skin, focusing on the oily T-zone and nose, then rinse thoroughly. Always follow with a hydrating toner and soothing moisturizer, and apply sunscreen the next morning. Avoid broken, irritated, dry, or sensitive skin, and don't combine it with leave-on acids or retinoids the same day.

Is it worth the price?

At around $12 for 25 single-use sachets — about fifty cents a treatment — the raw value matches the collagen version and is good for occasional use, with the convenience of consistent, portable dosing. But the value is conditional on fit: it's only worth it for resilient, oily skin used once or twice weekly, and for dry or sensitive skin no price offsets the barrier risk. The hyaluronic-acid finish is a minor preference tweak, not a value differentiator versus the collagen edition. Against a gentler low-pH leave-on acid — more controllable and often similarly priced per use — this is the more fun but riskier choice. Buy it for occasional oily-skin polishing, not as your main exfoliant.

Who should buy it

Consider it if you have oily, combination, or resilient skin, enjoy an occasional deep-polishing scrub, and prefer a hyaluronic-acid finish over the collagen version — provided you keep to once or twice weekly. The single-use sachets suit anyone wanting convenient, portable, consistently dosed exfoliation.

Who should skip it

Those with dry, sensitive, rosacea-prone, or barrier-compromised skin should avoid it, as should chronic over-exfoliators. Anyone who prefers gentler, more controllable exfoliation will do better with a low-pH leave-on AHA or BHA than a high-pH baking soda scrub.

What the first two weeks feel like

Mixed with water it forms a fizzy, gritty paste with a cooling mint tingle; skin feels notably smooth and de-greased afterward, with the hyaluronic acid leaving it a touch less tight than a plain baking-soda scrub. The mint scent is prominent.

The story behind it

Why it exists

Farm Stay offers its trendy single-sachet Baking Powder pore scrub in two near-identical versions, letting users pick their preferred conditioning agent; this hyaluronic-acid edition pairs the abrasive, fizzy base with a water-binding humectant instead of collagen.

About Farm Stay Established Brand (5–20 years)

Farm Stay is a high-volume budget Korean brand. This is the hyaluronic-acid version of its single-use Baking Powder Pore Scrub — the same baking-soda-and-acid exfoliating base as the collagen version, with sodium hyaluronate swapped in as the conditioning humectant, in convenient individual sachets.

Brand founded 2009

Myth vs. reality

What people get wrong about it

MythThe hyaluronic acid makes this baking-soda scrub gentle and hydrating.

RealityThe hyaluronic acid helps offset the stripped feel, but it doesn't change the fundamentals — 40% baking soda at pH ~9 plus physical grit and menthol is still an abrasive, barrier-challenging scrub. The HA softens the aftermath; it doesn't make frequent use safe.

FAQ

Questions people ask

How is this different from the Collagen Baking Powder scrub?

The exfoliating base is identical — 40% baking soda, silica and cellulose grit, and an AHA/BHA blend. The only meaningful difference is the conditioning agent: this version uses sodium hyaluronate (a humectant) where the other uses hydrolyzed collagen. Choose based on which finish you prefer.

Does the hyaluronic acid make it gentle?

It helps the skin feel less stripped afterward, but it doesn't change the core formula — 40% alkaline baking soda plus physical grit and menthol is still abrasive. Use it sparingly, once or twice a week, not as a gentle daily cleanser.

Who is this scrub best for?

Oily, combination, resilient skin with congested pores that enjoys an occasional deep-polish. Dry, sensitive, rosacea-prone, or barrier-compromised skin should avoid it due to the high-pH baking soda and physical exfoliation.

What's the ideal frequency for using the Baking Powder Hyaluronic Acid Pore Scrub?

Once or twice a week at most. The high baking soda content and physical particles make over-exfoliation easy, so keep frequency low and always follow with hydrating, soothing steps.

Why single-use sachets?

The powder-based formula is mixed fresh with water each time, so single sachets keep it convenient, portable, and consistently dosed — and the packet format naturally discourages over-frequent use.
