Ladies Get In Here! The Dangers of Using Milk Of Magnesia As A Face Primer Before Makeup


Makeup primers are used to provide an even “canvas” for the application of make up, they smooth over minor surface imperfections like fine lines, wrinkles and pores. There are different types of makeup primers, for example:

  1. Prime only: This is the most basic type of primer; it just gives your face a smooth surface that makeup will adhere better to. Most of these are a combination of a volatile silicone (e.g. Cyclopentasiloxane) with a heavier silicone (e.g. Dimethicone) as their main ingredients. Some are based on silicone and water. These may or may not contain mattifying ingredients, powders that help reduce shine (e.g. Silica, Magnesium Aluminium Silicate, Tapioca Starch, Aluminum Starch Octenylsuccinate,t.c). An example of “primer only” primer is Smashbox Photo Finish Primer.

  3. Prime plus colour correct
  4. Prime plus anti aging

Milk Of Magnesia (MOM) is mainly Magnesium Hydroxide suspended in water and some Sodium Hypochlorite. It is commonly used as an antacid. So when your stomach (pH level between 1.5 – 3.5) is very acidic and painful, MOM (pH level 10.5 – strong alkaline) is used to neutralize your stomach leaving you with water. (A little bit of chemistry here – acid + alkaline = water + salt).

Ammonia has a pH of 11, which is pretty close to the pH of MOM; imagine putting Ammonia on your face for hours. Yes, using MOM will stop the shining short term because Magnesium Hydroxide has very good absorbing qualities and Sodium Hypochlorite commonly known as bleach has degreasing attributes. What looks like the most amazing gift ever in the short term can completely wreak havoc on your skin in the long run.

The protective layer on the skin surface known as the “acid mantle” has a mildly acidic pH (about 5), which helps maintain skin integrity and keeps beneficial flora attached to the skin and bad flora like fungus away. MOM will increase the alkalinity of the skin thereby destroying this acid mantle, leaving your skin unprotected. Your skin becomes dry (loses moisture), prone to irritations; impede your skin’s ability to shed its dead layers and damage overall skin integrity.

This has the potential to be quite dangerous. Below are two primers that can help control oil; according to their ingredients list, I believe they should do a pretty good job. These primers are mattifying primers, if you have dry skin, I really won’t advice you to use them.

This has a pretty basic formula. The main ingredients here are Water and Magnesium Aluminium Silicate. Once applied, water will evaporate leaving Magnesium Aluminium Silicate which is a clay-derived absorbent (good for oil absorption) giving a powdery finish.

Just like the Becca Primer, the main ingredients here are Water and Magnesium Aluminium Silicate. Like I mentioned earlier, water evaporates once applied on the skin leaving Hydrated Silica, which is a good absorbent like Magnesium Aluminium Silicate.
