Vaseline: Does it really work for wrinkles and blackheads? A dermatologist reveals the truth

Vaseline, known for its powerful moisturizing effects at an affordable price, has been a beloved product for a long time, with many people owning at least one. However, some sources describe Vaseline as a panacea, claiming it can improve wrinkles, remove blackheads, or even serve as emergency treatment for burns. Many people are curious whether Vaseline truly possesses these effects and if it's safe to apply to the skin. Today, a dermatologist will directly address the myths and truths about Vaseline, which can be beneficial when used correctly but problematic when used improperly.

Korea's Ministry of Food and Drug Safety states that applying Vaseline topically is not problematic. This is because the molecular size of petrolatum, Vaseline's main ingredient, is large, making its absorption into the body when applied to the skin very unlikely. However, it cannot be used with complete confidence on all areas.

Therefore, Vaseline is generally suitable for external use on dry skin areas, and caution is needed when using it on sensitive areas such as the lips or inside the nose.

Many people are curious about Vaseline's effect on wrinkles. As we age, our skin tends to lose oil and become dry, and dry skin can lead to more fine wrinkles. Applying Vaseline to dry skin creates an oily film that prevents moisture from escaping, thereby preventing the skin from drying out. This means it can help prevent wrinkles.

However, it is difficult to improve already deep-set wrinkles with Vaseline. Deep wrinkles that have already formed are often due to sagging skin or damaged tissue, so in such cases, it is better to consider treatments like Botulinum Toxin or laser procedures that are effective for wrinkle improvement, rather than Vaseline.

Blackheads on the nose are very noticeable and many people want to remove them, but they are often difficult to get rid of. The 'Vaseline nose pack' that became popular online claims that applying Vaseline to the nose, covering it with plastic wrap, and then placing a hot towel on top will remove blackheads. While it might seem like the hot towel opens pores and the oil in Vaseline melts blackheads, the actual effects are as follows:

• Whitehead removal: Whiteheads may be somewhat removed as pores open with a hot towel. This can be attributed to the opened pores rather than Vaseline itself.
• Blackhead removal: The effect of removing deeply embedded blackheads is reported to be minimal.
• Skin irritation: Vaseline is an oil-based ingredient and is not easily washed off, requiring prolonged cleansing to remove it without residue. This process can actually irritate the skin.

Therefore, it is advisable to be cautious, as using Vaseline to remove blackheads may result in more harm than good.

It is well-known that wounds heal better when kept moist with a hydrocolloid bandage. The idea that applying Vaseline to a wound can help is based on the same principle. Vaseline not only keeps the wound moist but also forms an oily film that can protect against external contaminants such as viruses and bacteria.

However, Vaseline used at home may carry a risk of infection, so when a wound occurs, it is more appropriate to apply antibiotic ointment rather than Vaseline.

While Vaseline is indeed an excellent moisturizer, it is not suitable for all skin types. Especially for oily or acne-prone skin, the oily film created by Vaseline to prevent moisture loss can actually clog pores and cause acne. This point must be remembered.

Vaseline is an affordable and effective moisturizer, but an accurate understanding of its efficacy and usage is crucial. Please use Vaseline wisely, considering your skin type and condition.
