What is Skin Care Medication?

Clinical skin care preparations refer to the topical and systemic medications used for the prevention, management, or treatment of specific skin diseases.

While conventional cosmetics may only change the physical appearance of the outermost layer of the skin, the clinical skin care drugs comprise the APIs.

How Skin Care Drugs Work

Medication for skin conditions operates on various pathogenic mechanisms present in the skin layers.

There are four main physiological processes involved in their function:

• Catalyzing cellular turnover: In this case, the retinoids attach to the nuclear retinoic acid receptors, which cause differentiation between keratinocytes. This causes the damaged and aged cells to move up to the epidermal layer through the pore lining.
• Inflammation Inhibition: Such creams or ointments work as steroids to inhibit cytokine synthesis, the one that is resulting in symptoms of inflammation, itching, hives, and so on.
• Microbial Treatment: These skincare medicines will work against the bacteria, damaging their DNA replication process. Some others work by destroying the cell wall of the bacteria and making them prone to the harsh outside environment.
• Enzyme inhibition: There is a specific type of skincare medication known as tyrosinase inhibitors, which stop the production of enzymes like melanin, which helps to get rid of dark skin patches.

What Are Skin Care Medications Made Up Of?

A medicinal skin care formulation comprises two main components:

Main Pharmaceutical Substances: As you can understand by the name, the chief medicinal compound, which is present in the medicine, lotion, or ointment, actually helps to recover the symptoms or the actual infection.

A few examples of such substances are-

• Tretinoin for acne
• Benzoyl peroxide and Clindamycin for skin bacterial infections
• Hydrocortisone for reducing skin inflammation

Comparing Different Skin Care Drugs

Dosage Patterns of Skin Care Drugs

Dosing strategies for skin care medications are highly individualized and depend entirely on skin tolerance and structural resilience.

Topical Application (Retinoids/Acne treatments): Mostly initiated using a titration regimen.

Patients may be advised to apply a pea-sized amount once every 2 or 3 days all over their face to avoid any irritation, increasing frequency to a daily basis as tolerance develops.

Topical Steroids: Normally used in a very thin layer on the affected part, one or two times a day. The use is normally highly restricted to a short period (like one to two weeks).

Oral Medication: These need to be taken with water as they come in the form of swallowed tablets.

Remember that most of these are systemic drugs, which means that the doctors have to carefully structure a dose for the patient based on the infection type, age, and weight.

Side Effects of Skin Care Medications

Although skin care medications work effectively, altering cell function may result in some side effects. Localized side effects are the most common.

The Reutilization Phase: While starting retinoid medications, it is not uncommon to experience a period of localized dryness, flaking, redness, and mild burning sensation.

Such issues may be at their maximum by week 2 to 4, after which they will subside.

• Topical steroids: Excess use can cause atrophy or skin dryness and even dermatitis.
• Systemic Isotretinoin: Usually causes problems like chapped lips, dry eyes, high blood lipids, and possible joint pain.

Drug Interactions with Common Drugs

Benzoyl Peroxide and Tretinoin: Using both these skincare medicines may actually make the entire treatment ineffective. In case they are prescribed simultaneously, the doctors will recommend a time gap of at least 12 hours.

Multiple Acid Layering: layering topical retinoids can actually change the skin lipid barrier, which causes skin irritation on touch and even dermatitis.

Oral Retinoids and Tetracyclines: The combination of oral Isotretinoin along with tetracycline antibiotics is absolutely contraindicated since the likelihood of having benign intracranial hypertension (brain pressure increase) rises.

Specific Contraindications

Before starting a skin care medication regimen, review these critical clinical precautions:

• Teratogenicity (Birth Defects): Remember that systemic retinoids tend to cause birth defects. Using such treatments is not recommended at all during the time of pregnancy.
• Photosensitivity: Some retinoids, like alpha hydroxy acids or even antibiotics for skin infections, can cause skin sensitivity to sunlight.

It is important for the patient not to go out under direct sunlight with exposed skin, which can irritate, itching, or burning as a side effect.

Where Can I Get Skin Care Medications in Australia

The distribution of skin care medications in Australia is strictly regulated based on the scheduling of the active ingredient.

Over The Counter (Pharmacy Only/ Schedule 2 & 3): Milder forms of therapeutic remedies for acne, creams that contain mild doses of hydrocortisone, and formulations specifically meant for dandruff can be bought freely without any prescription.

Prescription Only Medicines (POA/Pharmacy Schedule 4): Highly potent retinoids (Tretinoin), antibiotic skin creams in combination with other medications, and oral skin medications must have an official prescription by a registered AHPRA doctor.

This may be available at a physical pharmacy or online pharmacies specializing in prescription skin medications.
