Stretch Mark Cream and the Cosmetic Versus Drug Line

Stretch mark cream sits in an odd spot because the condition itself, stretch marks, sounds medical, and a lot of makers assume that means the product automatically needs drug-level approval. It does not have to. What pushes a stretch mark product from cosmetic into drug territory is almost entirely the wording on your label and your marketing, not the ingredients underneath it.

What keeps it a cosmetic

A cosmetic can legitimately claim to improve the appearance of skin. "Helps improve the look of stretch marks," "for smoother, more even-looking skin," "visibly reduces the appearance of stretch marks," these are all appearance claims. They describe a cosmetic effect, something visible on the surface, without asserting that the product changes the underlying tissue or treats a medical condition. This is the same logic that lets a wrinkle cream stay cosmetic when it claims to reduce the look of fine lines, rather than claiming to rebuild collagen structure or heal skin damage.

Common ingredients in this category, cocoa butter, shea butter, various oils, centella asiatica extract, bakuchiol, peptides marketed for elasticity support, can all sit in a cosmetic formula filed as a normal notification. The ingredients are not the deciding factor here. The claim is.

What tips it into drug territory

The line gets crossed when the claim stops being about appearance and starts being about treatment, scarring, or a physiological healing process. Phrases like "treats scar tissue," "heals damaged skin," "repairs torn dermis," or "clinically proven to eliminate stretch marks" all imply the product is doing something beyond a surface-level, appearance-only effect. That reads as a drug claim because it asserts a therapeutic or structural effect on the body, which is the same reasoning that keeps sunscreen, anti-acne, and anti-dandruff products firmly in drug categories rather than cosmetic ones.

Here is a side by side of how similar-sounding claims land differently:

Claim wording	Likely classification
"Improves the appearance of stretch marks"	Cosmetic
"Visibly fades the look of scarring"	Cosmetic
"Helps skin look smoother and more even"	Cosmetic
"Treats and heals stretch mark scar tissue"	Drug-leaning
"Clinically proven to repair damaged collagen"	Drug-leaning
"Eliminates stretch marks by rebuilding skin structure"	Drug-leaning

Why "clinically proven" is its own trap

Even without the word "treat," stacking a strong efficacy claim like "clinically proven" onto a structural or healing claim compounds the problem. "Clinically proven to visibly reduce the look of stretch marks" is still describing an appearance effect and tends to stay cosmetic, assuming you can actually substantiate it. But "clinically proven to heal stretch marks" pairs a strong evidentiary claim with a therapeutic one, which reads as a much stronger drug signal. If you are using clinical study language, keep the underlying effect described as appearance, not tissue repair.

The ingredient list does not save a bad claim

We see makers assume that because their formula only contains cosmetic-grade humectants and plant oils, the label can say whatever sounds compelling. It cannot. Classification runs off the claim being made, not the ingredient deck. A perfectly ordinary body butter formula can still get flagged if the marketing copy promises to "repair torn skin fibers." Conversely, a formula with more active-sounding ingredients like peptides or retinol alternatives can stay cosmetic as long as the claims describe appearance rather than structural change or treatment of a condition.

A practical check before you finalize copy

Read your label and any product page copy and ask, for every claim:

1. Does this describe how the skin looks, or what is happening inside the skin?
2. Would a dermatologist read this as a cosmetic benefit or a treatment outcome?
3. Am I implying the product changes tissue, heals damage, or treats a medical condition?
4. If I swapped "stretch marks" for "wrinkles" in this sentence, would it still sound cosmetic?

If any answer points toward treatment or structural repair, revise the wording before you file. It is much cheaper to adjust copy now than to have a product pulled after Health Canada or a market surveillance review flags it as an unauthorized drug claim.

Since the notification itself only asks about the product and its ingredients rather than pre-approving your marketing claims, the responsibility for staying on the cosmetic side of that line sits with you as the notifier. Cosmetic Comply screens your ingredient list and formula against the Hotlist and gets it filed with a trackable CN number, but it is worth reading your own label copy with fresh eyes before submission, since claim wording is the part no ingredient screen can catch for you.
