Differin (Adapalene)

What Is Differin Gel

Differin is a popular topical medicine used to treat acne, pimples and papulopustular acne. Its active ingredient is adapalene at a concentration of 0.1%. It works by targeting the main processes involved in acne.

Adapalene is the active ingredient in Differin. It is a synthetic analogue of retinoic acid and belongs to a group of skin medicines called dermatotropic agents. Chemically, adapalene is a derivative of naphthoic acid. It selectively binds to retinoic acid receptors in the nuclei of epithelial cells and stimulates keratinocyte differentiation. At the same time, it does not bind to cytosolic proteins that are sensitive to retinoic acid. This helps explain why it is less likely to cause marked irritation.

Adapalene speeds up the final stage of keratinocyte transformation into keratinised scales and weakens the bonds between cells in the epidermis. This helps skin cells shed more quickly, thins the epidermis and reduces the formation of comedones. The medicine also helps clear hair follicle openings of built-up dead skin cells.

Where do pimples, blackheads and acne come from? The processes behind them are described in detail in medical literature. The main causes include:

• hormonal changes in the body;
• increased sebum production;
• enlarged skin pores;
• harmful microorganisms getting into the pores;
• the effects of previous illnesses, skin injuries or allergic reactions.

The product actively and quickly reduces sebum production. Another important effect is that it helps normalise keratinisation in hair follicles. Dermatologists' reviews of Differin gel and cream are generally very positive. Many say this medicine is one of the most effective options available for pimples, rashes and blackheads. The same is often said of Differin-related products made on its basis. Topical retinoids such as Adaklin and Klenzit are also widely used in acne treatment.

However, one point needs to be clarified. Differin on its own, without other medicines, may be used to help get rid of pimples, but not to treat more established acne. In those cases, it should be combined with products containing benzoyl peroxide or an antibiotic.

Product Description

According to the official instructions, the Swiss manufacturer's adapalene cream and gel should be used in the following cases:

• if you have comedones, severe acne or pimples
• if pustules or papules have appeared

It is worth paying attention to the terminology. The term "acne" implies the presence of closed or open comedones on the skin. Pimples can be classified as papules, which do not contain pus, and pustules, which do contain pus.

The instructions say these indications apply to pimples and to mild or moderate acne. The severity of the condition is assessed individually by a specialist during a consultation. This takes into account the extent and total number of inflammatory and non-inflammatory lesions on the face.

There are three forms of acne:

• A mild form of acne. At this stage, acne appears as blackheads and pimples (comedones). With this form of the condition, treatment may include tablets, topical retinoids, tretinoin, azelaic acid and external antibacterial agents. Tretinoin is currently considered one of the most effective treatments for mild acne;
• The average form of acne. Oily seborrhoea. In this case, treatment needs to be combined. This means tablets are used together with external medicines. For example, Differin may be combined with systemic or topical antibiotics. To achieve a therapeutic effect, the course of treatment should be prescribed by a doctor;
• A complex form of acne. The first step in treating this type of rash is to see an Australian dermatologist, beautician, endocrinologist and, for women, a gynaecologist. Only a combined assessment can help develop the right treatment plan. Treatment requires a systematic approach, with oral medicines used alongside external products such as creams, gels and ointments. In severe cases, treatment may include antibiotics, hormones and retinoids (products based on salicylic and azelaic acids).

What Differin (Adapalene) Gel Is Used For

The active ingredient in Differin, adapalene, has a soothing, drying, antiseptic, comedolytic, exfoliating and anti-inflammatory effect, while reducing activity in the sebaceous glands. It helps prevent acne, reduces oily shine and clears pores.

Benefits:

1. Breaks down the plug inside the sebaceous gland and stimulates changes in the shape of epithelial tissue cells.
2. Keratolytic action, which means exfoliation of the upper layers of the skin and a drying effect. This helps pimples dry out and clear more quickly.
3. Anti-inflammatory effect. It significantly slows the growth of bacteria that play a major role in acne.
4. Sebum-regulating action, which helps reduce skin oiliness. This makes the skin less favourable for bacteria.
5. Helps dissolve comedones. Inflamed pimples often develop because of comedones, or clogged pores. Clearing comedones is one of the most important steps towards clearer, healthier-looking skin.
6. Helps improve post-acne marks, especially spots left after acne. Suitable for sensitive skin.

Differin Acne Treatment

Differin gel for acne targets the causes of skin blemishes. The product offers a wide range of effects:

• exfoliation of dead skin cells from the upper layers of the dermis;
• support for skin renewal, which may make expression lines and age-related wrinkles less noticeable;
• improving skin firmness and smoothing skin texture;
• the active substances in the acne gel penetrate the upper layers of the epidermis and stimulate the natural production of elastin and collagen, while also helping to deeply cleanse and disinfect the skin.

The substance works through keratinisation. This is a complex process that takes place in the upper layers of the epidermis and involves the deposition of keratin. Keratin acts as a natural shield against various harmful influences and microorganisms.

Because Differin acne treatment reduces the conditions that allow bacteria to multiply, the healing process can be quicker and more effective. Its anti-inflammatory and bactericidal components also help reduce redness and improve the appearance of the skin. This can have a positive effect on confidence and self-esteem.

Before Taking This Medication

Like any targeted treatment, Differin ointment has some contraindications and restrictions. These include:

• an allergic reaction to any of the ingredients
• breastfeeding or pregnancy
• age under 12 years
• eczema, dermatitis or seborrhoea, although these contraindications are relative.

How To Use Differin Gel

How to use Differin gel: Differin Gel is for external use only and is best applied before bed, when the skin is actively renewing itself. Before applying it, wash your face thoroughly with soap or a cleanser and dry it with a paper towel. Using light massaging movements, apply the gel or cream locally, only to the areas affected by pimples and acne. It is important not to use adapalene gel on mucous membranes, wounds, damaged skin or the border of the lips. Avoid getting it in your eyes.

Dosage For Differin

Apply Differin adapalene gel evenly to the affected areas of skin once a day before bed, without rubbing it in. The product should be applied to clean, dry skin. A therapeutic effect usually develops after 4 to 8 weeks of treatment, with sustained improvement after 3 months. Repeat courses may be recommended by a doctor. Différin is indicated for the treatment of mild to moderate acne as monotherapy, and for moderate acne in combination with other topical medicines such as antibiotics or benzoyl peroxide, and systemic medicines such as antibiotics or oral antiandrogens.

How Long To Use It

If you have oily, porous and shiny skin, you may notice the first results within a few days. Your skin may look less shiny and less greasy, although it still takes time to see the full effect. This improvement may last all day, and in some cases until the next day. As for the number of pimples and acne spots, monotherapy with Differin can help. You may see the first visible changes after about a month of use. Pimples may clear completely in around 2.5 months, especially in more stubborn cases.

You can expect visible results only after a full course of treatment, which is at least 3 months. This timeframe applies when monotherapy is prescribed to help get rid of pimples. If it is used as part of combination therapy, Differin should be combined with antimicrobial medicines. For example, treatment may include medicines containing antibiotics and benzoyl peroxide. Most importantly, effective combination therapy usually works faster than using a single medicine on its own.

Areas Differin Gel Should Not Be Used On

Avoid applying the gel or cream to the eyes, lips and mucous membranes. If the medicine accidentally gets into the eyes, mouth or nose, rinse thoroughly with warm water. Avoid direct sunlight, as it may cause mild skin irritation. Treatment can be continued if sun exposure is minimised, for example by wearing sunglasses and a hat.

Using cosmetics that have a drying or irritating effect on the skin, such as perfumes or alcohol-containing products, is not recommended at the same time. Differin Gel applied in the evening may be combined with acne products applied in the morning.

Differin Gel Side Effects

Differin gel side effects may include itchy skin, redness and burning. If these symptoms appear, you should stop using the cream, then restart it after some time. During the first 14 days, the product should not be used every day, but only several times a week. Allergies sometimes occur in people with dry, sensitive skin.

Common Side Effects

If any of the side effects listed in the instructions get worse, or if you notice any other side effects not listed there, tell your Australian doctor straight away.

Common Side Effects:

• dry skin,
• skin irritation,
• a burning sensation of the skin,
• erythema.

Uncommon Side Effects

Uncommon Side Effects:

• allergic dermatitis (allergic contact dermatitis),
• skin soreness,
• swollen skin,
• eyelid irritation,
• erythema of the eyelids,
• itchy eyelids,
• swollen eyelids.

Drugs, Substances, Or Supplements Interactions

Because the medicine does not interact with oxygen and is not broken down by light, it may be used with other topical or systemic acne medicines such as clindamycin phosphate or benzoyl peroxide.

Differin During Pregnancy And Breastfeeding

Clinical experience with the external use of adapalene during pregnancy is limited, but available data from patients treated in early pregnancy do not show harmful effects on pregnancy or fetal health. Because the available data are limited, and because a small amount of adapalene may pass through the skin, Differin should not be used during pregnancy.

No studies have looked at whether the medicine passes into breast milk in animals or humans after skin application. Because overall exposure to Differin in breastfeeding women is very low, no effects on breastfed children are expected. Differin can be used while breastfeeding. To avoid the infant coming into contact with the medicine, do not apply it to the breast area while breastfeeding.

After Using The Medication

Exposure to sunlight and artificial ultraviolet light, including sunlamps, should be minimised during the use of adapalene to help prevent skin irritation. If exposure cannot be avoided, sunscreen and protective clothing are recommended for treated areas of skin.

When using Differin gel for wrinkles, you can use cosmetics that are not comedogenic or astringent. Differin cream contains methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216), which may cause allergic reactions during or after treatment.

Storage

Store at a temperature not exceeding 25°C (77°F). Do not freeze. Keep out of reach of children.

Disposal

Shelf life is two years. Do not freeze the cream to extend its shelf life. After the expiry date, dispose of it in line with local requirements.

Alternative Medications

If severe acne has been diagnosed, retinoids such as Differin are generally not prescribed, as they are unlikely to be enough on their own. In this case, effective options may include systemic retinoids based on isotretinoin, which are taken by mouth. These include Acnekutan and Roaccutane.
