As I express strongly, it is crucial to know what skin type your client has and what to do during makeup application. Be mindful of the excess oils your clients skin will reproduce despite the amount of layers you may apply. As a HMUA, it is important you have products that include all skin types. For oily skin, I suggest you use a ‘oily skin’ skincare as this specialises in rehydrating the skin, however, removing dirt and excess oil on the skin. Simply cleanse once, then remove this with cotton pads and warm water then dispose. Lightly tone the face using cotton pads in a swiping motion. I would suggest using a light moisturiser as this will replenish the skin, however, not influence additional excess oils. For primer, I would suggest a pore filling and mattifying primer as this will help reduce shine and help the skin appear smoother. For foundation, I would suggest using a medium thickness as this will create a great base/barrier for excess oil as this will be harder for the oil to break down the foundation. Personally, I prefer a matter/natural finish as the foundation will become oilier and shinier throughout the day, blotting and light powder applications will solve this throughout the day. Try to not use lots or creams, as this is oil based and this will make the skin reproduce more oil and become cakey and shiny over a long period of time. Lightly, set the t-zone and under the eyes and proceed makeup applications. Overall, with a few alterations and knowledge, you will achieve your overall desired makeup look despite the clients skin type.
