Methylparaben: Is It Actually Safe?

Written by Anjali Sayee

Much is made of methylparaben in skin care products. Most people are wary of this ingredient and try to avoid it. Methylparaben, like other parabens, is used in skin care products as an antimicrobial agent and preservative. But how risky is it to use it, and how much harm can it cause to the skin? Scroll down to find out the truth.

What Is Methylparaben And Why Is It Used In Skin Care?



Parabens are preservative esters added to skin care products in concentrations of 0.8% (a blend of parabens) to 0.4% (individual paraben). Parabens are of different types:

  • Methylparaben
  • Propylparaben
  • Ethylparaben
  • Isopropyl paraben
  • Butylparaben
  • Isobutylparaben
  • Benzylparaben

Out of all, methylparaben is frequently used in cosmetics. It naturally occurs in blueberries and is developed synthetically in labs. It is used in cleansers, lotions, moisturizers, masks, gels, tanning lotions, and baby skin care products (between 0.3% and 0.5%). Methylparaben serves a purpose in skin care products. Let’s take a look at its benefits.

Benefits Of Adding Methylparaben To Skin Care Products

  1. Methylparaben has antimicrobial and antifungal
  2. It has no specific odor or taste, a neutral pH level, and does not discolor or turn murky. This property of methylparaben increases the shelf life of the products.

Methylparaben is not available as a separate ingredient and has no such skin benefits. It is incorporated in products.

How To Use Methylparaben And How Often

Methylparaben is used in different concentrations (not more than 0.5%) in all skin care products. You can use them as per the manufacturer’s instructions.

It can be used on all skin types except eczema-prone, acne-prone, and sensitive skin. Methylparaben is used in small concentrations in products and considered to be safe. However, there are some side effects you need to be aware of.

Side Effects Of Methylparaben

  1. Parabens may increase the risk of breast cancer as they penetrate the skin and remain in the breast tissue. They can also disrupt endocrine function (thyroid and adrenal glands) and cause structural and functional changes in the skin. This may increase the skin’s rate of UV absorption and lead to skin cancer.
  2. One of the main concerns regarding methylparaben is it can mimic estrogen and may disrupt hormonal balance and thyroid function.
  3. A study on mice found that methylparaben could activate TRPA1 channels (sensory neurons) and stimulate pain sensations.
  4. Research on toxicity levels of methylparaben shows that it may irritate the skin when used in high concentrations.
  5. Methylparaben may have a disruptive effect on the reproductive system in women. Research shows that parabens remain in the blood and affect menstruation and cause reproductive issues.
  6. Parabens may cause allergic contact dermatitis and lead to skin inflammation such as blisters, burning sensations, and rashes.

Parabens are used in low concentrations in skin care products. However, if you want to avoid them completely, you can go for safer alternatives.

Are There Safer Alternatives?

There are many paraben-free products available on the market. These are safer options and don’t affect your health and skin as parabens do. Also, you can check for products with plant-based preservatives.

To Conclude

Methylparaben is used in skin care products as a preservative to increase their shelf life. In low concentrations, it may not affect your skin health. However, it can penetrate the skin and reach the bloodstream and may lead to health issues. If you want to avoid it, you can use paraben-free products or look for products with plant-based preservatives.
