There isn't a single acid that removes hyperpigmentation fast. However, various acids are known to be effective in treating hyperpigmentation, though the speed of results varies depending on the individual and the severity of the condition.
Here are some acids commonly used for hyperpigmentation:
- Kojic acid: Derived from a certain type of fungus, kojic acid is effective for all types of hyperpigmentation, including post-inflammatory, sun-induced hyperpigmentation, and age spots.
- Tranexamic acid: This acid can be used orally or topically and helps reduce excessive pigmentation.
- Glycolic acid: A type of alpha-hydroxy acid (AHA) used in chemical peels to remove the superficial layer of the skin, which can help fade hyperpigmentation.
- Salicylic acid: Another AHA, salicylic acid helps to exfoliate the skin and can be effective in treating acne-related hyperpigmentation.
- Azelaic acid: This acid is known to reduce inflammation, inhibit melanin production, and lighten dark spots.
- Retinoids: These are vitamin A derivatives that can help to increase cell turnover and reduce the appearance of hyperpigmentation.
It's important to note that the effectiveness of any acid treatment can vary based on individual factors and the type of hyperpigmentation. Consulting a dermatologist is always recommended to determine the best treatment plan for you.
