Enlarged pores: the best beauty procedures for clear skin and tightened pores

Table of contents

Pores are small openings on the surface of the skin that allow sweat and oil to drain. They are therefore essential for the good balance of the epidermis and to let the skin breathe . But they sometimes become large and very visible, whether due to genetics, exposure to the sun or lack of care. You cannot make enlarged pores disappear , but it is possible to improve their appearance with suitable products. Nooance Paris presents the beauty procedures to adopt to tighten pores and regain healthy, radiant skin .

What are the most common causes of enlarged pores?

Sebum production

This is the most common cause of enlarged pores: the more sebum the skin produces, the larger and more visible the pores become. This is why combination and oily skin generally has larger pores than normal or dry skin.

Indeed, sebum is directly produced by the sebaceous glands, at the base of what is called the pilosebaceous follicle, and rises to the surface of the skin through a channel. The higher the production, the more the opening of the channel will tend to widen: this is what affects the appearance of the pores and therefore also their size.

This sebum production can be linked to several factors:
- Hormones : for example, we observe a peak in sebum production at the time of puberty.
- Sex : men have higher sebum production due to higher testosterone levels.
- The environment : heat, humidity, lifestyle and pollution influence the quality of the skin and can cause skin imperfections. Researchers have notably demonstrated that sebum production increases in spring and summer, when the temperature is highest.

But other factors also influence the appearance of pores.

The influence of age

As we age, pores tend to enlarge because the skin loses elasticity, making pores appear larger. The skin's natural exfoliation process, called cell turnover , is slowing down. Dead cells therefore remain on the surface of the skin longer and can clog them, which can stretch the pores of the skin and make them more visible and larger.

UV exposure

Exposure to ultraviolet rays has consequences on the quality of the skin (spots, wrinkles, thinning of the skin) and therefore also affects the appearance and dilation of pores. Indeed, UV rays stimulate metalloproteinases, which are collagen-destroying enzymes. This results in a reduction in the presence of collagen and therefore the appearance of fine lines and wrinkles, as well as a loss of firmness, which can be the cause of larger pores.

How to reduce the appearance of pores?

You now know the possible causes of your enlarged pores, but how can you make them less visible ? Here are some tips for having beautiful skin every day and choosing the most suitable cosmetic products for your skincare routine.

The ideal beauty routine for less visible pores

Step 1: Effective cleaning

The first thing to do to tighten the pores of the skin is obviously to have good hygiene and to clean your face with a product adapted to your skin type . It is not necessary to exfoliate your face every day to smooth the skin's texture: a gentle daily cleanser is enough to remove impurities and dead skin.

Step 2: Properly moisturize your skin

It is generally believed that skin that produces a lot of sebum should not apply moisturizer, otherwise it will result in shiny skin. But hydration is essential even for oily skin: a good humidity level allows better cell regeneration. Opt for light moisturizers, in the form of serum for example, which will not weigh down oily skin and clog pores.

Step 3: Protect yourself from the sun

In order to avoid premature aging of the skin and therefore a reduction in collagen, it is important to protect yourself by applying a sunscreen product with at least SPF30 . The harmful effects of the sun on skin texture can only be avoided by applying sunscreen every day, summer and winter, as a makeup base before foundation.


The key ingredients to favor in your products

Sebum-regulating active ingredients: vitamin B3, retinol

Enlarged pores are often caused by excessive sebum production. It may therefore be interesting to treat them with targeted natural active ingredients . They will act on oily skin to regulate sebum production without drying it out.

  • Vitamin B3 , also known as niacinamide. In several studies, vitamin B3 applied at a rate of 2% to 5% for 4 to 6 weeks helped reduce sebum production in volunteers.
  • Retinol . It is an ingredient that decreases sebum production by reducing the size and secretion of sebaceous glands. In addition, it activates cell renewal.


It is also possible to use an exfoliating treatment such as glycolic acid or salicylic acid . These two active ingredients eliminate excess sebum on the surface of the skin, as well as dead cells, which helps reduce the size of pores.

Nooance-Paris: innovative treatments to prevent and treat enlarged pores

The multi-active serum with hyaluronic acid

Nooance's multi-active serum enriched with 5% vitamin B3 hydrates and plumps the skin thanks to the presence of 5 hyaluronic acids of different molecular weight, i.e. different molecule sizes. It reduces wrinkles thanks to the presence of antioxidants to preserve skin health as well as several peptides that stimulate the production of collagen and elastin to improve firmness and elasticity.



It helps even out the complexion and reduce brown spots thanks to the presence of arbutin. It soothes and strengthens the skin barrier thanks to the presence of ceramides and centella asiatica, a plant of Asian origin known for reducing irritation and redness, as well as panthenol which is provitamin B5. This super light serum is suitable for all skin types and can be used morning and/or evening on cleansed skin.


Anti-aging night care with retinol

Nooance anti-aging treatments contain retinol at 0.6% and 1%. These two treatments are identical, the only difference being the percentage of retinol. It is combined with other active ingredients to maximize the effectiveness and benefits of the product on the skin. For example, we find 5% vitamin B3, which affects the appearance of enlarged pores, as well as anti-aging peptides, vitamin C and antioxidants from green tea.


Hydration and maintaining the skin barrier are very important to reduce the size of enlarged pores. This is why these creams contain moisturizing and soothing active ingredients such as panthenol (or provitamin B5), centella asiatica, ceramides, which are lipids naturally present in our skin, prebiotics and Allantoin.
