    If your goal
    is to make your face falling off then it will work. Are you making a nuclear
    bomb or what? Your formula isn’t equal 100% and you are trying to make a
    concoction with 3% of hydroquinone and tretinoin (how much?). These are not
    toys. Learn how to make simple o/w lotions first then move to actives. I am not
    even sure you can buy tretinoin and hydroquinone.

    @ngarayeva001 those are the serial numbers, but still agree that not for newbie.

    Sorry it showed as 3.1% on my phone. But I think any amount of hydroquinone is not safe for a beginner. Start from simple products and then move to actives.

    @Jake99 Definitely start with a regular lotion as @ngarayeva001 suggested.
    You are missing an emulsifier to keep the water and petrolatum together. As you are starting out as a newbie try something along the lines of simple formulas from lotioncrafter.com or makingcosmetics.com
    You should also be aware for the future that Clindamycin is not a cosmetic ingredient. It is a drug (antibiotic) which could lead to the development of MRSA strains if misused.
    Tretinoin is likewise a drug compound, OTC in the US. The compound is prone to oxidation and requires a decent amount of experience to formulate a stable and safe product.
    You can read a lot on hydroquinone on the forum, but I would suggest steering clear of it altogether.

    Thank you.I’ll do as you recommended?
    I thought mixing hydroquinone with clindamycin would be like a two in one product.will they react though?just curious..thanks

    @Jake99
    I don’t know the regulations in the country where you live, but I don’t think you can buy clindamycine either (same with tretinoin as mentioned by ngarayeva001), they’re not cosmetics.

    Edit: I see Sibech has answered this in the mean time.

    @Jake99 No Chemically clindamycin is not likely to react with hydroquinone as is.
