The "Johnsons White Cosmetics Developer Vol 20 200ML" is a facial and hair product used for bleaching and skin polishing. The brand "Johnson White Cosmetics" is a well-known name in the beauty industry, especially in the Pakistani market, for its skin care and hair care products.

Here's a detailed breakdown of the product and its uses:

Product Type: This is a developer, or "Facial Blonde Activator" as it's sometimes called by the brand. It is an oxidizing agent that, when mixed with a bleach powder, activates the bleaching process.

Volume 20 (20 Vol): This indicates the strength of the developer. A 20-volume developer is a standard, medium-strength developer. It's strong enough to lighten hair by 1 to 2 levels and is also a common choice for covering grey hair. It is generally considered safe for use on the skin when mixed with a facial bleach powder.

Size: The product comes in a 200ML bottle, which is a good size for personal and repeated use.
