What is acne?

Acne is a common inflammatory skin condition. It mainly appears in the form of pimples (papules, pustules), comedones (blackheads, whiteheads), and sometimes cysts or nodules. Hair follicles play a central role in the development of acne. When they become clogged due to an excess of sebum (the natural oil produced by the sebaceous glands) and the accumulation of dead cells, this creates an environment conducive to the proliferation of bacteria, particularly Propionibacterium acnes, the main bacterium responsible for acne. As these microorganisms multiply, they trigger an inflammatory reaction that leads to inflammation and the appearance of skin lesions. Acne mainly affects the face, neck, back, chest, and shoulders.

Note: Acne ranges from mild to severe, with potential impacts on self-esteem and quality of life. Acne management may involve topical treatments, oral medications, and lifestyle changes.

What causes acne?

Acne is a multifactorial skin condition, meaning it can result from several interacting factors. Although it is often associated with adolescence due to hormonal fluctuations, it can also affect adults. Poor lifestyle choices and certain external aggressors, such as pollution, can aggravate symptoms. Below, we detail the main factors that can contribute to the onset of acne:

Excess sebum

The sebaceous glands in the skin produce sebum, a natural oil that lubricates and protects the skin. When these glands produce too much sebum, it can clog pores, creating an environment conducive to the appearance of pimples.

Accumulation of dead cells

The skin is constantly renewing itself, but when this process is disrupted, dead cells can accumulate on the skin's surface. These cells clog pores, which, combined with excess sebum, can lead to the formation of comedones (blackheads and whiteheads).

Hormonal fluctuations

Hormonal changes, particularly an increase in androgen hormones, can stimulate the sebaceous glands to produce more sebum. This is why acne is common during adolescence, the menstrual cycle, pregnancy, or in cases of hormonal disorders such as polycystic ovary syndrome (PCOS).

Stress

Stress does not directly cause acne, but it can aggravate symptoms. It stimulates the production of hormones, such as cortisol, causing hormonal imbalances that increase sebum production and inflammation.

Unsuitable diet

Although the links between diet and acne are still debated, some studies suggest that foods with a high glycemic index, dairy products, and foods high in fat can aggravate acne in some people.

Comedogenic cosmetic products

The use of certain cosmetic products that contain comedogenic ingredients (i.e., ingredients that clog pores) can contribute to the appearance of acne. Adopting a suitable skincare routine and using non-comedogenic products can help limit these effects.

How can you recognize acne?

Recognizing acne involves observing several symptoms that appear mainly on the face, back, chest, and shoulders. Find out below how to identify the main signs of acne:

Blackheads (open comedones): small black or dark bumps on the surface of the skin. The black color is due to the oxidation of sebum in the open air, not dirt. They are mainly located on the nose, forehead, and chin (T-zone).
Whiteheads (closed comedones): small white or flesh-colored bumps that form when the hair follicle is blocked by sebum and dead skin cells. Unlike blackheads, they are not exposed to the air. They are often found on the face, back, and chest.
Papules: small red, inflamed bumps with no visible white head. They are often sensitive to touch and are found on the face, shoulders, neck, back, and chest
Pustules: red spots with a white or yellowish head in the center, filled with pus. These are the "classic spots" of acne. They appear in the same areas as papules, often in combination with them
Oily skin: Oily skin is shiny, especially in the T-zone (forehead, nose, chin) where there are a large number of sebaceous glands. Oily skin is a skin type caused by excessive sebum production. The pores may appear enlarged.
Redness and irritation : Red and inflamed areas on your face, especially around acne lesions, are also signs of acne-prone skin.

Presence of skin lesions

Blackheads (open comedones): small black or dark bumps on the surface of the skin. The black color is due to the oxidation of sebum in the open air, not dirt. They are mainly located on the nose, forehead, and chin (T-zone).
Whiteheads (closed comedones): small white or flesh-colored bumps that form when the hair follicle is blocked by sebum and dead skin cells. Unlike blackheads, they are not exposed to the air. They are often found on the face, back, and décolleté.
Papules: small red, inflamed bumps with no visible white head. They are often sensitive to touch and are found on the face, shoulders, neck, back, and chest.
Pustules: red pimples with a white or yellowish head in the center, filled with pus. These are the "classic pimples" of acne. They appear in the same areas as papules, often in combination with them.

Oily skin

Oily skin is shiny, especially in the T-zone (forehead, nose, chin) where there are a large number of sebaceous glands. Oily skin is a skin type caused by excessive sebum production. The pores may appear enlarged.

Redness and irritation

Red and inflamed areas of your face, especially around acne lesions, are also signs of acne-prone skin.

What is a natural active ingredient?

Natural active ingredients used in skin care products offer a multitude of benefits. These ingredients, extracted from plants, minerals, or other natural sources, are often preferred for their gentle effectiveness and their respect for the integrity of the skin and the environment. Some natural active ingredients have antibacterial and anti-inflammatory properties, which can help limit acne-related blemishes and soothe irritation.

How to use natural active ingredients to combat acne?

Applying natural active ingredients to treat acne requires a few simple and appropriate steps to reap the full benefits. When chosen and used correctly, these active ingredients can help purify the skin, maintain its balance, and limit the appearance of blemishes. Below are the key steps for incorporating them effectively:

Gently cleanse: start with Organic Cucumber & Hyaluronic Acid Micellar Water. Apply it to a washable cotton pad and gently wipe your face, eyes, and lips to remove makeup, sebum, and impurities. Gentle movements are enough, no need to rub. Use it morning and evening to keep your skin clean and ready for the next steps in your skincare routine.
Rebalance with a concentrated lotion: then apply Niacinamide 5%, Zinc & Hyaluronic Acid Toner to clean skin, using a cotton pad or directly with your hands. Pat gently to promote optimal absorption of the active ingredients. Water-based textures should always be applied before serums or thicker creams. If you make your own skincare products, niacinamide and zinc can be incorporated into water-based formulas (lotions, gels, serums) and added cold at the end of preparation, following the recommended dosages.
Moisturize and target imperfections: follow with Organic Purifying & Hydrating Fluid. Apply a small amount to the face and neck, then massage in with smoothing movements, focusing on areas prone to imperfections. Its light texture moisturizes without leaving a greasy residue, while helping to mattify the skin. Introduce exfoliating active ingredients gradually and avoid using too many in a single application to keep your skin comfortable.
Protect the skin: In the morning, finish with Mineral Sunscreen Lotion SPF 20 on all exposed areas. Apply a sufficient amount before exposure and reapply as needed. Sun protection is particularly important when using a product containing salicylic acid or other exfoliating active ingredients, in order to limit marks and maintain the skin's balance.

How can you prevent acne?

Adopting good daily habits can help limit the appearance of acne and maintain more balanced skin. Below, we share a few simple tips to incorporate into your daily routine:

Cleanse your skin : morning and evening, with a gentle product suited to your skin type, to remove excess sebum and impurities.
Apply a non-comedogenic sunscreen: even on cloudy days, to protect your skin while preventing clogged pores.
Moisturize your skin: choose a light texture if you have combination or oily skin to maintain its balance and promote the healing of blemishes.
Eat a balanced diet: focus on fruits, vegetables, and foods rich in omega-3, while limiting foods with a high glycemic index, dairy products, and processed foods.
Drink enough water: about 1.5 liters per day to help regulate sebum and support overall skin health.
Avoid touching or popping pimples: this limits irritation, infection, and the risk of scarring.
Limit the use of comedogenic products: makeup, creams, or oils that are too rich can clog pores and promote the appearance of pimples.
Choose soft, breathable fabrics: cotton clothing and pillowcases help reduce friction and moisture, which can irritate the skin.

Precautions

Some natural active ingredients may cause unwanted skin reactions. Always test the product on the inside of your elbow, for example, to check for any allergies. Please note: some active ingredients need to be diluted before performing an allergy test. Be sure to refer to the recommendations on the product information sheet. Be careful about sun exposure after applying certain active ingredients that may be photosensitizing. Use sunscreen daily to avoid any discomfort.

Expert advice

Your skin's microbiome deserves as much attention as your beauty routine. An imbalance in skin bacteria can promote blemishes and make skin more sensitive. To support its natural balance, choose gentle skincare products that are suited to your skin type and enriched with prebiotic or soothing active ingredients, while limiting the use of harsh cleansers. Soothed and balanced skin is better able to regain its radiance.

There is no miracle product that can eliminate acne overnight. Effectiveness depends on the nature of the acne, its severity, and skin type. For mild to moderate acne, skincare products concentrated in natural active ingredients, such as salicylic acid or niacinamide, can help reduce blemishes and improve the appearance of the skin. In cases of more severe acne, dermatological follow-up is recommended, as more powerful treatments, sometimes based on topical antibiotics, may be necessary to achieve lasting and safe results.

There are several effective natural solutions for reducing blackheads. A green clay mask, applied once or twice a week to the T-zone, purifies the skin and regulates sebum, while pink clay is a gentle alternative for sensitive skin. Salicylic acid gently exfoliates and prevents the accumulation of dead cells, thus limiting the appearance of blackheads. Finally, a facial sauna, or steam bath, helps to open the pores and liquefy sebum, preparing the skin for the action of purifying treatments and enhancing their effectiveness.

Acne spots do not disappear instantly; it is strongly advised not to touch or squeeze them. Over time, by taking care of your skin with gentle actions suited to acne-prone skin, inflammation will decrease, excess sebum production will be regulated, and blemishes will be less likely to reappear.
