Yes, you can use alpha arbutin with niacinamide and salicylic acid. Alpha arbutin is a skin-brightening ingredient that helps to reduce the appearance of dark spots and hyperpigmentation. Niacinamide is known for its ability to improve skin texture, reduce the appearance of pores, and even out skin tone. Salicylic acid is a beta hydroxy acid that helps to exfoliate the skin, unclog pores, and reduce acne breakouts.

When using these ingredients together, it's important to consider the potential for skin sensitivity or irritation, especially if you have sensitive skin. Start by introducing one product at a time into your skincare routine and observe how your skin reacts. If you experience any redness, dryness, or irritation, you may want to consider using these ingredients on alternate days or adjusting the concentration of each ingredient.

Additionally, it's important to note that the pH of the products can also affect their efficacy. Niacinamide works best at a pH of around 5-7, while salicylic acid is most effective at a lower pH of around 3-4. Make sure to check the pH of the products you are using and ensure they are compatible with each other.

Overall, it is possible to use alpha arbutin with niacinamide and salicylic acid, but it's important to listen to your skin and adjust your routine accordingly. If you have any concerns or questions, it's always a good idea to consult with a dermatologist or skincare professional.
