Beauty Soap 100gm

• Free kojic acid sits first on the list: Not the dipalmitate ester. It reaches the skin unchanged rather than needing to be broken down first.
• Arbutin backs it up: A second tyrosinase inhibitor at a gentler pace, so the bar is not relying on one ingredient alone.
• Vitamin B3 and pro-vitamin B5 stay behind after rinsing: Both are water-soluble and deposit lightly, which is unusual in a bar this active.
• Glycerin and mineral oil soften the wash: Sodium palmate and sodium oleate clean hard; those two stop it stripping the skin bare.
• A moisturizing soap that still lathers properly: Sodium lactate keeps the bar firm so it does not turn to paste in a humid bathroom.

• Kojic acid: The raw form, not an ester. It acts directly on the pigment enzyme but oxidises in air, which is why kojic bars brown.
• Arbutin: Slower and steadier than kojic acid, and far less likely to irritate. In a rinse-off bar it is the ingredient doing quiet, cumulative work.
• Sodium palmate and sodium oleate: The soap itself — saponified palm and olive oils. Palmate makes the bar hard, oleate makes the lather creamy.
• Pro-vitamin B5. Panthenol, included to offset the SLS: It is the reason this bar feels less tight afterwards than most kojic original acid soap bars.
• SLS. A strong cleanser and a known irritant for some: If bar soap has ever left your face stinging, this is usually why.
• Mineral oil Superfatting: A small amount left unsaponified so the bar deposits a trace of oil instead of stripping everything off.

A browning bar is normal here and not a fault, but it does mean the kojic acid is oxidising. Keep it dry between washes and use it within a few months. How kojic acid behaves goes into why.

Full ingredient list (INCI) — verbatim from the catalogue

Kojic Acid, Arbutin, Vitamin B3, Pro Vitamin B5, Titanium Dioxide, SLS, Glycerin, Sodim Lactate, Sodium Palmate, Sodium Oleate, Mineral Oil & Fragrance.

1. Lather in your hands first, then apply the lather. Do not rub the bar directly on your face.
2. Thirty to sixty seconds on the skin, then rinse with lukewarm water.
3. Once a day to begin with, in the evening. Twice only if your skin shows no tightness after two weeks.
4. Follow with a moisturiser every time. A bar with free kojic acid and SLS in it is not a standalone routine.
5. Stand it on a draining dish. A bar left in water softens, and the kojic acid degrades faster when wet.

Beauty bar vs soap — is there a real difference?

Yes. A true soap is made by saponifying oils with alkali, which is what this is: sodium palmate and sodium oleate are the giveaway. A beauty bar is usually a synthetic detergent bar built around milder surfactants at a lower pH. Soap cleans harder; a syndet bar is gentler on a compromised barrier.

Why has my bar turned brown?

Free kojic acid oxidises when exposed to air, light and water, and the colour shift is the visible sign of it. The bar is still safe to use, but it is losing potency. Buy one at a time rather than stocking up, and keep it out of a sunlit bathroom.

Should I buy this or the Fairness Soap?

This bar if your skin is robust and you want the more direct form of kojic acid. The Fairness Soap if you are sensitive, because its dipalmitate ester is gentler and more stable. They are not two grades of the same thing — they are two different trade-offs.

Can I use it on my body?

Yes, and a 100gm bar goes a long way on arms, underarms and knees. Body skin is thicker and generally tolerates it better than the face. Avoid broken skin and freshly shaved areas, where free kojic acid will sting noticeably.

How long does one bar last?

About six to eight weeks with once-daily facial use, less if you use it on the body too. Kept dry it holds up well; left sitting in water it will soften and disappear in half that time. Storage makes more difference than frequency here.

Will it dry my skin out?

It can. SLS plus a true soap base puts this at the stronger end of cleansing, and the glycerin, panthenol and mineral oil only partly offset that. Tightness within a minute of rinsing means drop to alternate days. Tightness that persists means switch products.

Is it safe to use around the eyes?

Keep it away from the eye area entirely. The skin there is thin, kojic acid stings on contact, and SLS in the eye is genuinely unpleasant. Wash the rest of the face with the lather and use something plain around the eyes, or simply rinse that area with water alone.

Can I use it alongside a brightening cream?

Yes, and that is the sensible pairing. The bar handles cleansing and leaves a little active behind; the cream does the sustained work. Do not add a third kojic acid product on top — the point of diminishing returns arrives well before the point of irritation.
