Preparing Your Skin Before a Cosmetic Treatment

Why the Days Before Your Appointment Deserve Real Attention

The results you see after a cosmetic treatment are shaped long before you sit in the chair. Whether you are booked in for a facial peel, microneedling, laser, injectables or a skin-boosting treatment, your practitioner is working with the skin you bring them. Calm, well-hydrated, undisturbed skin responds more predictably, heals faster and carries far less risk of irritation, infection or uneven results. Think of the week before as part of the treatment, not simply the wait for it.

The good news is that none of this is complicated. A little restraint with your usual skincare, a bit more moisture and a frank conversation about your health will do more for your outcome than any expensive product.

Press Pause on Retinoids and Strong Acids

This is the single most common piece of advice you will hear, and it is worth following carefully. Active ingredients that speed up cell turnover — retinol, retinal, tretinoin, adapalene and prescription retinoids in particular — leave skin thinner, more sensitive and more reactive. Alpha-hydroxy acids such as glycolic and lactic acid, beta-hydroxy acids like salicylic acid, and stronger exfoliating acids do something similar.

• Stop retinoids and prescription vitamin A products for around five to seven days before treatment, or longer if your practitioner asks.
• Pause glycolic, salicylic, lactic and mandelic acids, plus at-home peel pads, for three to five days.
• Skip physical scrubs, cleansing brushes, dermaplaning and enzyme exfoliants in that final week.
• Avoid waxing, threading and hair removal creams on the treatment area for at least a week.
• Hold off on self-tan, sunbeds and spray tans — many practitioners cannot treat tanned or recently tanned skin safely.

If you are unsure whether a product counts as an active, bring it with you or send a photograph of the ingredients list to the clinic. Nobody minds the question.

Hydration Does More Than You Think

Well-hydrated skin is more pliable, more comfortable and noticeably more tolerant of trauma. In the week before your appointment, drink water consistently rather than in a panicked rush on the morning itself, and keep a simple, fragrance-free moisturiser in daily use. Look for ingredients such as glycerin, hyaluronic acid, ceramides and squalane, which support the skin barrier without causing irritation.

• Cleanse gently with a mild, non-foaming wash and lukewarm water.
• Apply moisturiser morning and evening, and again after any exposure to wind or cold.
• Use a broad-spectrum sunscreen of SPF 30 or higher every day, even in winter or under cloud.
• Turn the heating down a notch and consider a humidifier if your skin feels tight indoors.
• Keep showers short and warm rather than long and hot.

Do not use the week before treatment to try a new serum, acid or mask. New products can trigger reactions, and a rash on treatment day usually means a cancelled appointment.

Tell Your Practitioner Everything Relevant

Honesty here protects you. Your practitioner needs to know about medication, supplements and health conditions because these affect bleeding, bruising, healing and how your skin will respond.

• Blood thinners, including warfarin, rivaroxaban and clopidogrel, plus daily aspirin.
• Painkillers such as ibuprofen and other anti-inflammatories, which can increase bruising.
• Supplements including fish oil, high-dose vitamin E, ginkgo, ginger and St John's wort.
• Isotretinoin, a prescription acne treatment derived from vitamin A, which usually requires a waiting period of several months before many procedures.
• Antibiotics, especially tetracyclines, which can make skin photosensitive.
• Hormonal treatments, immunosuppressants and steroids, whether topical or oral.
• Pregnancy or breastfeeding, which rules out a number of treatments and products.
• Cold sores — a history of them may mean your practitioner recommends an antiviral beforehand.
• Allergies to lidocaine, latex, adhesives or specific skincare ingredients, and any tendency to keloid scarring.
• Previous treatments, including dermal fillers, botulinum toxin, threads or permanent make-up, and when you had them.

Never stop a prescribed medicine on your own. Speak to your GP or pharmacist first, then pass that information on to the clinic.

The Last 24 to 48 Hours

Keep this window calm and simple. Avoid alcohol for at least 24 hours, as it thins the blood and increases the chance of bruising. Cut back on caffeine if you bruise easily, and skip intense workouts, saunas and steam rooms on the day before and the day of treatment.

• Eat something light before you arrive — low blood sugar makes some people feel faint.
• Come with clean, product-free skin if you can, and leave make-up off on the day.
• Wear loose, comfortable clothing that will not rub the treated area.
• Reschedule if you are unwell, feverish or have an active cold sore or skin infection.
• Plan a quiet evening afterwards and avoid booking anything important in the following 48 hours.

Ask your practitioner for written aftercare instructions before you leave, and check which products you can restart and when. A few days of care beforehand, and a clear plan afterwards, will give your skin the best possible chance of a smooth, comfortable recovery and results you are genuinely pleased with.
