Etude Baking

Sodium bicarbonate (baking soda) has a pH of around 8.3, which is higher than the skin's natural slightly-acid pH of approximately 4.5-5.5. When it contacts oily sebum, which is an acidic substance, the bicarbonate acts as a mild base and helps break down the sebum's structure. This makes it effective at dissolving the oily debris that accumulates in pores without needing harsh synthetic detergents.

The physical form of the baking powder granules also contributes: fine particles provide gentle mechanical exfoliation when massaged across the skin surface. The combination of chemical action (pH-based sebum dissolution) and mild physical action (granule abrasion) is what makes baking soda a practical ingredient in pore-focused cleansers.

The main consideration is that baking soda's alkaline pH temporarily shifts the skin's surface pH away from its natural range. Following up with a slightly acidic toner after cleansing helps restore the skin's pH balance. This is why ETUDE's own Wonder Pore Freshener is a logical follow-up step after using any Baking Powder cleanser.

The Baking Powder Pore Cleansing Foam is the standard daily cleanser in the line. It comes in both 160ml and 300ml sizes, and the formula is the same across both. The 160ml is practical for travel, countertops where space is limited, or first-time buyers who want to try the product before committing to the larger size. The 300ml is more economical for regular daily users.

When dispensed and lathered, the foam has a dense, cushiony texture. The baking powder granules provide a mild gritty sensation when first applied, then the foam takes over. Rinse time is important - baking soda can leave a residue if not thoroughly rinsed, particularly around the hairline and jaw. Lukewarm water is recommended; hot water can strip the skin further after an already alkaline cleanse.

This is primarily a product for oily and combination skin types. Used twice daily (morning and evening), it provides consistent sebum control throughout the week. For other skin types, alternate-day use is a more sustainable approach.

The Crunch Pore Scrub increases the physical exfoliation intensity of the baking powder concept. Where the Cleansing Foam uses fine granules for mild abrasion during washing, the Scrub contains coarser particles designed for a more deliberate buffing action. The name "crunch" refers to the audible and tactile texture when the product is applied.

Use the Scrub once or twice a week, not daily. On scrub days, it replaces the Cleansing Foam - you do not need to use both in the same session. Apply a small amount to damp skin, massage gently in circular motions with light pressure for 30-60 seconds, then rinse. Avoid the eye area entirely. The coarser particles can cause micro-abrasions if pressed too hard, so the guiding principle is light pressure and let the product do the work.

The 200g tube is a full-size home product. A single-serve sachet format (7g × 24) is also available for travel or hygiene-focused users who prefer not to reach into a shared tube. Each sachet covers one full-face application.

The "Bebe" (baby) variant is ETUDE's reformulation of the Baking Powder concept for sensitive or delicate skin. The "Bebe" name is borrowed from the Korean cosmetics convention of using baby-skincare terminology to signal gentleness rather than age-targeting. It is a cleanser for adults with reactive, sensitized, or easily irritated skin who still want the cleansing benefit of the baking powder formula without the same intensity as the standard Pore Cleansing Foam.

The formula is adjusted to be milder - lower concentration of baking soda and a gentler surfactant system. It lathers less densely than the standard foam and rinses off without the slight squeaky-clean tightness that some people experience with the Pore Cleansing Foam.

The 30ml travel size is particularly useful as a trial: it lets you see how your skin responds to the baking powder ingredient without the commitment of a full 160ml bottle. If your skin tolerates it well, the 160ml is the standard ongoing size.

The BB Deep Foam is formulated specifically for removing BB cream (the Korean tinted moisturizer that blends coverage with skincare). BB cream sits at the heavier end of tinted products and often requires a dedicated cleansing step to remove completely, particularly from pores. A standard cleanser can leave a thin film of pigment behind if the formula is not strong enough to break down the BB cream's oil-based components.

The BB Deep Foam adds micellar-type cleansing agents alongside the baking powder to break down the oily pigmented film of BB cream more effectively than the standard foam alone. It is available in both 30ml and 160ml sizes. For people who wear BB cream daily, this variant makes more sense than the standard Pore Cleansing Foam as an evening cleanser.

Note that the BB Deep Foam, despite its targeted formulation, works as a general daily cleanser and is not limited to BB cream removal. It handles regular sunscreen, sebum, and environmental impurities as well. The BB cream focus is the functional enhancement, not a restriction on use cases.

With four distinct products in the line, the choice comes down to your skin type and what you primarily need from a cleanser:

• Daily cleanser for oily or combination skin: Baking Powder Pore Cleansing Foam (160ml or 300ml). This is the workhorse of the line, suited for twice-daily use on oilier skin types.
• Weekly exfoliation step: Baking Powder Crunch Pore Scrub (200g or 7g × 24). Used 1-2 times per week on top of your regular cleansing routine, replacing the foam on scrub days.
• Sensitive or reactive skin: Baking Powder Bebe Deep Cleansing Foam (30ml trial or 160ml). A gentler version of the same concept for skin that tends to react to stronger cleansers.
• Daily BB cream wearer: Baking Powder BB Deep Foam (30ml or 160ml). Formulated with extra cleansing agents to break down BB cream pigment along with sebum.

If you want to use multiple products from the line, a practical combination is the BB Deep Foam as your daily evening cleanser (for makeup removal days) plus the Scrub once or twice a week for texture maintenance.

The Baking Powder line is stocked in several sizes, each suited to different use cases:

• 30ml: Trial or travel size, available in the Bebe and BB Deep Foam variants. A 30ml tube provides approximately 30-45 daily applications for a single user depending on how much product they use per wash.
• 160ml: Standard home size, available across most variants. Suitable for one person using the product once or twice daily, lasting 3-5 months.
• 200g: The Crunch Pore Scrub home size. Larger than the standard cleanser sizes because scrub formulas are denser and used in larger per-session amounts.
• 300ml: Economy size of the Pore Cleansing Foam. Most practical for daily users who want to reduce repurchase frequency or for households where more than one person uses the product.

The Baking Powder cleansers sit at the first step of any skincare routine: they are wash-off products applied before toner, serum, and moisturizer. A standard sequence:

1. Wet your face with lukewarm water.
2. Pump or squeeze a small amount of the cleanser onto your palm. For foam products, about a 2cm diameter dollop is sufficient. For the scrub, a hazelnut-sized amount is enough for one application.
3. Lather between palms, then massage onto the face in circular motions for 30-60 seconds. Be gentle around the nose and chin, which are often the most sebum-prone areas.
4. Rinse thoroughly with lukewarm water. Run your fingers over the hairline and jaw to ensure no product remains.
5. Follow immediately with a toner (such as the ETUDE Wonder Pore Freshener) to help restore skin pH after the alkaline cleanse.

On days you use the Crunch Pore Scrub, skip the Cleansing Foam and use only the scrub as your cleansing step. Do not layer multiple exfoliating products in the same session.
