Let’s keep this in mind before we start the milk carton.

Everyone must have washed their face with expired milk in the refrigerator at least once. Too familiar milk is drawing attention again online recently. Unlike in the past, when used as a finishing cleansing product, pack with milk and remove dead skin cells and sebum. Many beauty YouTubers introduced whitening and moisturizing care methods using milk, and there were a number of comments saying that they actually had the effect of clearing their skin. Milk care, which is full of compliments, is it okay to follow it blindly regardless of skin type? For safer and more reliable care, I checked with a dermatologist.

Q1. Milk, why is it good for your skin?
Milk contains lactic acid, one of the AHAs known as chemical exfoliating ingredients. Lactic acid is extracted from milk or dairy products, and in addition to exfoliating, it is also used as a moisturizing and pH regulator. In addition, it has various peptides that help skin elasticity and vitamin E, an antioxidant.

Q2. Milk rich in beneficial ingredients,
Can you see the effects of using it on your skin?
Since these ingredients actually exist, they can be effective if the skin fits well with milk. However, caution is needed depending on the skin type. Milk is not a refined cosmetic for the skin, so if you have sensitive skin, test it on your body skin and use it.
Q3. Can I use expired milk?
Since lactic acid, which is effective in exfoliating skin, is obtained by fermentation of lactose and glucose, it can be considered that expired milk is effective for the skin. However, expired milk deteriorates from its existing properties and bacteria can reproduce, and if it is used on the skin as it is, troubles can occur. Using expired milk is more damaging than benefiting the skin.
Q4. Is there any special precautions?
Even if there is no chemical ingredient, washing your face after milk care is essential. It is also recommended to wipe clean with lukewarm water or use a light gel cleanser. Milk itself does not irritate the skin, but avoid using it only for milk allergies or purulent acne.

1. Skin care for your heels.
Method: Soak the entire foot in milk, wait for about 20 minutes, and rinse with lukewarm water.
The dead skin cells cannot be removed just by dipping their feet in EDITOR COMMENT’S milk, but the changes on their heels have been moistened. The savory scent unique to milk was not bad either. Since the heels and elbows, which are prone to keratinization due to their thick skin layers, are not sensitive areas, no irritation or abnormalities are felt even if expired milk is used. Let’s now yield expired milk to feet instead of faces.

2 cotton pads.
After washing your face, soak the cotton pad with milk and place it on your cheeks, chin, and lips. Before the milk dries completely (about 15 minutes), remove the cotton pad and rinse it clean with lukewarm water.
EDITOR COMMENT’S original skin layer is thick, so I bravely challenged the milk mask. Contrary to worries, there was no problem with the skin. I temporarily experienced the skin becoming moist and soft. It has a similar effect to a toner pack, but the milk soaked in cotton does not dry faster than the toner and lasts longer. The lips have also become noticeably softer. The hard but soft dead skin on my lips. It would be a good idea to try a lip mask by mixing honey.

3. Remove sebum.
Method: Wet the heated milk with cotton pads and cotton swabs. Place the cotton pad on the butterfly zone for 15 minutes, remove it, and roll it with a cotton swab wetted together.
EDITOR COMMENT’S milk has experienced the effect of removing softened sebum and dead skin cells to some extent. It’s too much to remove blackheads as in online reviews, but it feels like my skin has definitely gotten smoother than before. Usually, nose packs are irritating, so they use oil to remove sebum, which has a similar effect. There is little irritation and the effect is immediate, so I will often use milk to remove sebum in the future!

4. Skin care for your scalp.
Method: Wet a cotton pad with milk and massage it as if wiping off the scalp. Repeat the parting by changing the part and wash it clean with shampoo.
