    It was actually DIYed by a chemist friend for me. I don’t know how he achieved the Salicyclic acid solubility in water.

    Thank you very much.

    Your response is very helpful.

    Concerning the Salicylic acid 1%, I am thinking of using Glycolic acid 2% instead for some level of exfoliation suitable for daily use. Would that be okay? I know in large amounts, glycolic acid is very irritating.

    It’s noted.

    And can I add extracts like licorice and centella asiatica as your formulation is now?

    That’s very interesting.

    Aren’t a skin penetration enhancer (like Propylene Glycol), a pH adjuster (like lactic acid or TEA) and an antioxidant (like tocopherol) needed though?

    Indeed, I am doubting he is a newbie in cosmetic formulations, hence why I turned to this forum.

    I have asked him about the pH.

    Yes, I believe in a minimalist approach to formulation as well.

    For the aforementioned concerns (targeting melasma in the outer layers of the skin, post-acne hyperpigmentation and dark spots), how would you formulate the above formulation using a minimalist approach?
