Common questions about Mederma (FAQ)
Q: Is Mederma safe to use on older scars, or only newer ones?
Official product information suggests a specific duration of daily use based on the scar’s age. Use for established, older scars may be suggested for a longer period, such as three to six months, compared to the duration recommended for newly healed scars.
Q: Does Mederma work on acne scars?
Specific Mederma formulations, such as the Scar Cream + SPF 30 product, are regulated for use on scars resulting from acne. This is in addition to the product's intended use for scars caused by surgery, burns, or general injuries.
Q: What is the difference between Mederma and a basic skin moisturizer?
Regulatory labeling classifies Mederma as a combination over-the-counter drug, primarily categorized as a Topical Emollient and Skin Protectant. While it helps retain moisture (like a basic moisturizer), it is also formulated with the botanical extract Cepalin, and its intended purpose is the aesthetic improvement of scars.
Q: Are there different versions of Mederma, like a cream versus a gel?
The Mederma product line is available in different formulations. These include a gel (such as the Advanced Scar Gel), creams (like the PM Intensive Overnight Cream or Cream + SPF), and specialized products for use on children.
Q: How long do I usually need to use Mederma before official sources suggest reviewing results?
Product directions provide guidance on the expected duration of use. For newly healed scars, the suggested continuous daily use is often for at least eight weeks. For older or established scars, daily use may be suggested for three to six months.
Q: Is it okay to use Mederma and then put makeup or sunscreen over it?
Official product information generally indicates that Mederma can be used safely with other cosmetic products, including lotions and makeup. Product information suggests allowing the product to fully absorb and dry before applying other topical products.
Q: Can Mederma be used on any part of the body, including the face?
The product is regulated for topical application to the scar tissue. Official regulatory labeling does not contain specific restrictions on the area of the body where the product can be applied, provided the skin is intact and healed.

Q: Can I use Mederma if I have sensitive skin?
The official warning on product labels advises that if a localized skin reaction, such as irritation, is experienced and it worsens or persists for more than seven days, the regulatory label indicates that use should be stopped and a healthcare professional should be consulted.
Q: Does Mederma interact with any common topical antibiotics?
Official regulatory information does not specify a list of medicines or product classes that are contra-indicated for use with Mederma. There are no known significant pharmacokinetic interactions reported for the topical components, as they are formulated to work locally with minimal systemic absorption.
Q: Why is the active ingredient (onion bulb extract) used in Mederma?
The proprietary botanical component, Cepalin (Allium Cepa Bulb Extract), is included as part of the product’s Triple Action Formula. It is intended to support mechanisms such as enhancing skin hydration, promoting the reorganization of scar tissue, and dampening localized inflammatory responses.
Q: Is Mederma meant to flatten scars or just change their color?
The product’s intended benefit, as described in product information, is to improve the overall aesthetic quality of scars. This includes helping the scar become noticeably softer and smoother, which supports a more regular and flatter dermal surface organization.
Q: What are the inactive ingredients in Mederma?
The list of inactive ingredients varies depending on the specific product formulation (e.g., gel versus cream). These ingredients are explicitly detailed on the official drug facts label for each product and may include purified water, alcohol, xanthan gum, lecithin, and various preservatives.
Q: Does Mederma contain parabens or common preservatives?
Certain Mederma formulations list preservatives in the inactive ingredients section of the official drug facts label. For example, the Advanced Scar Gel formulation lists Methylparaben and Sorbic Acid as ingredients.
Q: Can I use other lotions or creams at the same time as Mederma?
Official product information indicates that Mederma can be safely used with other cosmetic products such as lotions and makeup. Product information generally suggests allowing Mederma to fully dry before applying other creams or lotions.
Q: Does Mederma cause the skin to be more sensitive to the sun?
Official labeling does not list the product as a known photosensitizing agent. However, general warnings for topical skin products advise users to always consider limiting sun exposure or using sun protection when spending time outdoors.
Q: Is it normal to feel a tingling sensation after applying the product?
Officially documented local adverse reactions at the application site include stinging and irritation. While 'tingling' is not specifically listed, it is closely related to these sensations. If any irritation is persistent or worsening, official warnings indicate that use should be stopped and a doctor should be consulted.
Q: Are there different recommended uses for Mederma on surgical scars versus injury scars?
Regulatory guidance and product directions typically differentiate the recommended duration of use based on the age of the scar (newly healed versus established/older). The directions generally do not vary based on the specific origin of the scar, such as whether it resulted from surgery or a general injury.
Q: Is there a limit to how long I can continue using Mederma?
Product directions suggest a defined treatment course designed to align with the natural duration of scar maturation. For established scars, this course is often recommended for three to six months of continuous daily use.
Q: Why do official sources sometimes mention different application times?
Differences in application frequency are based on the product’s active ingredients. Formulations containing sunscreen are mandated to be reapplied frequently while exposed to the sun, whereas the core scar management regimen is typically directed for once-daily use.
Q: Is it required to wash the treated area before each application?
Product information suggests applying the product when the skin is clean. This helps ensure optimal absorption into the scar tissue.
Q: Can Mederma be used for stretch marks?
The Mederma product line includes a specific, distinct formulation called Mederma Stretch Marks Therapy. This is a regulated product that is clinically studied and intended for use on stretch marks, separate from the primary scar management gel or cream.
Q: Is Mederma a product that must be used continuously for effectiveness?
The product directions recommend that Mederma be used daily for the duration of the defined treatment course. This continuous regimen is suggested to align with the process of scar maturation.
