Water Solutions
The Ordinary products typically are either water-based or oil-based, and it's important you apply your water-based products first. For your morning routine these include:
If you are using a retinol such as The Ordinary Retinol 1% in Squalane or The Ordinary Granactive Retinoid Emulsion 2%, these should be used only at night time as retinol can make your skin more sensitive to UV rays and they work best overnight.


After Water Solutions
The Ordinary Magnesium Ascorbyl Phosphate 10% has an emulsion formulation, meaning it should be applied after water solutions and before oil-based products and can be used in both the morning and the evening.
The Ordinary Vitamin C Suspension 23% + HA Spheres 2% should also be applied after water solutions and before oil-based products but should only be used in the evening, and not in the same session as The Ordinary Niacinamide 10% + Zinc 1% as the two ingredients can react and weaken each other.


Oil-based Products and Creams
Once you have applied you water-based solutions and suspensions, it's time to use your heavier oil-based products and creams. These can all be used in both the morning and the evening. It's recommended you start with only using one of these especially if you have an oily complexion.
The Final Step
The Ordinary do offer a more traditional moisturiser, The Ordinary Natural Moisturizing Factors + HA which can be used in the morning and evening to rehydrate skin. It should be the final step of your skincare routine to lock in moisture.
