Detailed answer

Generally, skin brighteners can be purchased over-the-counter without a prescription. These products typically contain ingredients like hydroquinone, retinol, vitamin C, or niacinamide, which are considered safe for topical use. However, it is important to follow the instructions provided with the product and conduct a patch test before applying it to your entire face or body. If you have any specific concerns or skin conditions, it is advisable to consult with a dermatologist or healthcare professional to ensure the best course of action for your individual needs. They may recommend prescription-strength skin brighteners for more severe cases or for specific skin conditions.
