Retinoids, Peels, and Injectables: Stopping Before Your Appointment

You've booked your appointment. You're excited. Maybe it's your first time trying a chemical peel, or you're coming back for your quarterly Botox, or you've finally decided to try Secret RF Microneedling after reading about it for months. Whatever brought you here, there's one thing that can quietly work against your results before you even walk through the door: not knowing what to stop using — and when.

This isn't about overwhelming you with a checklist. It's about understanding the why behind the guidance, so you can make smart decisions and arrive in the best possible condition for whatever you have planned. At Physician Artistry, Dr. Thomas reviews every patient's skincare routine and treatment history before recommending a plan — because what's sitting on your bathroom shelf matters more than most people realize.

Why Your Skincare Routine Affects Your Treatment Outcomes

Your skin is always in some state of activity. Retinoids are speeding up cell turnover. Exfoliating acids are loosening the bonds between surface cells. Active serums are signaling inflammation or renewal pathways. These are all good things — when timed correctly.

But when you layer an in-office treatment on top of already-active skin, the results can be unpredictable. Sensitivity increases. Healing slows. Peeling becomes excessive rather than controlled. Injectables may diffuse differently in inflamed tissue. None of these outcomes are catastrophic, but they can mean discomfort, longer downtime, or results that fall short of what was possible.

The pause before your appointment isn't a punishment for having a good skincare routine. It's a bridge between your at-home work and the clinical level-up you're about to receive.

Retinoids: The Most Important Thing to Stop First

Retinoids — including prescription tretinoin, retinol, retinaldehyde, and adapalene — are among the most effective anti-aging ingredients available. They accelerate skin cell turnover, stimulate collagen production, and progressively improve texture, tone, and fine lines over time. If you're using one, keep using it. Just not right before your appointment.

Here's why this matters: retinoids thin the stratum corneum (the outermost layer of skin) and increase photosensitivity and fragility. When you come in for a Secret RF Microneedling session or a chemical peel while your skin is actively retinoid-primed, you're introducing significant trauma to tissue that's already in a state of accelerated renewal. The result can be excess irritation, prolonged redness, or uneven peeling that wasn't part of the plan.

General guidance:

• Chemical peels and microneedling: Stop retinoids 5–7 days before your appointment. For deeper peels or RF microneedling, your provider may ask for a full 7 days.
• Botox and filler appointments: Retinoids don't directly affect neurotoxin placement, but if you're receiving injectables alongside any skin treatment in the same session, pause as above. For standalone Botox, most patients can continue their retinoid routine up until the day before — just avoid applying it directly after injection.
• Post-treatment: Wait until your provider clears you before reintroducing retinoids — typically 5–7 days after peels or microneedling, less for most injectable-only appointments.

If you're newer to retinoids or curious about how they fit into a larger treatment plan, the piece on skin cycling with med spa treatments goes deeper on how to sequence your at-home and in-office routine for the best long-term results.

Chemical Exfoliants: AHAs, BHAs, and Enzyme Peels

Alpha hydroxy acids (glycolic, lactic, mandelic), beta hydroxy acids (salicylic), and enzyme-based exfoliants are tremendously useful for ongoing skin maintenance. But they operate on the same principle as retinoids when it comes to pre-treatment timing: they're loosening and removing surface skin cells, which makes your skin more reactive going into any procedure.

General guidance:

• Before chemical peels: Stop all at-home exfoliants (AHAs, BHAs, enzyme cleansers or masks) 3–5 days prior. Your in-office peel is a controlled acid application — coming in with skin that's already been exfoliated aggressively can push the result past what was intended.
• Before microneedling or RF microneedling: Stop 3–5 days before. Freshly exfoliated skin has a compromised barrier, and creating micro-channels in compromised skin increases sensitivity without increasing benefit.
• Before injectables: Exfoliants don't typically interfere with Botox or filler injections directly, but they can make skin more reactive. If you notice your skin is irritated or sensitized from recent exfoliation, mention it at your appointment.

Injectables: What to Stop to Reduce Bruising and Swelling

For patients coming in for Botox, dermal fillers, or any other injectable treatment, the focus shifts from skin sensitizers to blood-thinning substances. Bruising after injectables is common and usually minor — but it's also largely avoidable with a little preparation.

The following increase your risk of bruising and should be paused before injectable appointments:

• NSAIDs (ibuprofen, aspirin, naproxen): Stop 5–7 days before, unless prescribed by your physician for a medical reason — in which case, discuss with Dr. Thomas before adjusting anything.
• Alcohol: Avoid for at least 24–48 hours before your appointment. Alcohol is a vasodilator, which means it widens blood vessels and makes bruising more likely.
• Fish oil, vitamin E, flaxseed oil: These have blood-thinning properties. Pause 5–7 days before. You can resume after.
• Certain herbal supplements: Ginkgo biloba, garlic supplements, ginseng, and St. John's Wort are all known to affect clotting. Stop these 5–7 days before injectable appointments.

This is a good moment to revisit our full guide on how to prepare for a Botox or filler appointment — it covers the complete list of do's and don'ts in one place.

One thing that doesn't need to stop: your arnica supplements, if you already take them. Many patients find that starting arnica 2–3 days before their appointment helps reduce the appearance of any bruising that does occur. Ask your provider if this makes sense for your situation.

Vitamin C and Active Serums: Context Matters

Not everything needs to be paused. Vitamin C (L-ascorbic acid) is often fine to continue before injectable appointments and doesn't interfere with neurotoxins or filler placement. However, if you're using a high-concentration vitamin C serum (20% or above) and you're coming in for a peel or microneedling, it can increase irritation on sensitized post-treatment skin if applied immediately after. The simple rule: stop it the day of your appointment for any procedure that affects the skin barrier, and wait for your provider's clearance before reintroducing it.

Similarly, benzoyl peroxide and prescription antibiotic topicals should be mentioned to your provider before any resurfacing treatment — not necessarily stopped, but reviewed in context of what's planned for your appointment.

What to Tell Your Provider (Even If You're Not Sure It Matters)

Here's the thing: you should tell Dr. Thomas or any Physician Artistry provider everything you're using, even if you're not sure it's relevant. That includes:

• All prescription skincare (tretinoin, topical antibiotics, topical steroids)
• Over-the-counter actives you use regularly
• Supplements and herbal treatments
• Any recent procedures done elsewhere, including facials, dermaplaning, or waxing
• Recent sun exposure or sunburn
• New medications — especially blood pressure medications, which can affect bruising, or hormone therapies

This is exactly the kind of comprehensive, thoughtful approach that sets a physician-led practice apart from a walk-in chain. A 30-second conversation before your appointment can be the difference between a result that surprises you (in the best way) and one that leaves you waiting longer than necessary for your skin to calm down.

One Week Out: A Simple Pre-Appointment Checklist

If you're not sure where to start, here's a practical week-by-week framework based on what's most commonly relevant:

7 days before any appointment:

• Stop NSAIDs (if possible and medically appropriate)
• Stop fish oil, vitamin E, and blood-thinning supplements
• Stop retinoids if your appointment involves any skin procedure

5 days before:

• Stop at-home chemical exfoliants (AHAs, BHAs, enzyme treatments)
• Avoid aggressive facial treatments (dermaplaning, at-home microneedling devices)

48 hours before:

• Stop alcohol consumption
• Avoid intense sun exposure — come in with protected, unexposed skin if possible

Day of your appointment:

• Come in with clean, moisturized skin — no heavy makeup, especially for facial treatments
• Skip vitamin C and any active serums on the morning of your procedure
• Stay hydrated — this genuinely matters for both filler results and healing

The Bigger Picture: Timing Is Part of the Treatment

One of the things that distinguishes a physician-led practice is that Dr. Thomas thinks about your treatment plan across time, not just within a single appointment. Knowing when to pause your skincare is part of the same thinking as knowing which treatments work better together, or understanding why the sequence of treatments matters as much as the treatments themselves.

Good preparation doesn't mean doing less. It means doing things at the right time so that what you invest in your skin — at home and in our office — actually delivers what it's capable of delivering.

If you have questions about your specific routine before an upcoming appointment, call us or bring your product list with you. We'd rather spend five minutes reviewing your skincare than have you leave your appointment wondering why your results weren't quite what you expected. That's not how we do things here — and it's not how you deserve to be treated.
