Cold sores can be painful, frustrating, and unpredictable. Whether they’re triggered by stress, weather changes, illness or hormones, flare-ups often come at the worst time  and how you treat them matters.

Many over-the-counter products for cold sores contain harsh ingredients that can sting, dry out the lips, or cause further irritation. That’s why a gentle, skin-focused routine is essential one that not only supports healing but helps you feel more comfortable and confident in your skin.

In this blog, we’ll break down what not to do during a cold sore, and why AfterMED Lips Cold Sore Support is your go-to for calm, clean aftercare that actually feels good.

What to Avoid During a Cold Sore Flare-Up

Let’s start with the basics. Cold sores caused by the herpes simplex virus (HSV-1) — can be made worse by certain habits, ingredients, or even your go-to lip balm.

Here’s what to avoid:

1. Picking or Touching
   It’s tempting to touch a cold sore  especially when it’s itchy or scabbing, but doing so can introduce bacteria, delay healing, and increase the risk of spreading the virus to other areas (or other people).
   
   

2. Alcohol-Based Balms
   Many traditional cold sore products include camphor or alcohol, which can feel cooling at first but often lead to dryness, stinging, and irritation especially on broken or inflamed skin.
   
   

3.  Fragrances & Flavourings
   Perfumes, essential oils, or synthetic flavourings may smell lovely, but they’re also common irritants, particularly when applied to cracked, vulnerable skin during a flare-up.

4. Heavy Lip Products or Makeup
   Covering a cold sore with lipstick, liner, or gloss may hide it temporarily, but makeup can trap bacteria and worsen discomfort. Not to mention, removing it later can be rough on delicate lips.
   
   

5. Sharing Lip Products or Utensils
   HSV-1 is highly contagious. Sharing lip balms, drinks or utensils can pass the virus to others  even when sores aren’t visible.
