In short: Silicone has the stronger body of clinical evidence for the appearance of raised scars and is described as a first-line option in scar-management guidelines, while aloe vera is valued for comfort, hydration and being gentle on sensitive skin. They are not really rivals. Silicone is the evidence-led choice for raised marks, aloe is the kind everyday-care choice, and some people use both. Here is a neutral, honest comparison to help you choose.
Search for scar products and you will quickly meet two camps: silicone gels and sheets on one side, plant-based oils and aloe creams on the other. It is tempting to ask which one wins, but that framing is misleading. The better question is which suits your scar, your skin and your priorities. Let us lay out both fairly.
What the evidence says about silicone
Of all the non-invasive options, silicone is the one with the most supporting research. International scar-management guidelines, including widely cited practical guidelines published in plastic and reconstructive surgery journals, describe silicone gel and sheeting as a first-line option for managing raised hypertrophic and keloid scars, and for reducing the likelihood of such scars forming after surgery. A Cochrane review has examined silicone sheeting in this context too. The benefits in the literature are often described as modest rather than dramatic, but silicone remains the most evidence-backed self-care measure available.
Silicone works by forming a thin, breathable, occlusive layer over the scar. It is generally well tolerated, though some people experience itching or dryness. It typically needs consistent daily use over many weeks to months, which is the part most people underestimate.
Where aloe vera fits
Aloe is a different proposition. As a cosmetic, it does not carry the same scar-specific clinical evidence as silicone, and it is not positioned to. What an aloe-rich cream offers is comfort: it hydrates, soothes and softens the skin around a settled mark, leaving it feeling supple. For people with sensitive, reactive skin who find some products harsh, that gentleness is genuinely valuable. We go deeper into the realistic role of aloe in our piece on aloe vera and scars.
Aloe also pairs naturally with daily massage, which many people find keeps the skin around an older scar feeling soft and flexible. In other words, aloe earns its place through comfort and consistency rather than through clinical claims.
A neutral side-by-side
| Consideration | Silicone gel or sheeting | Aloe vera cream |
|---|---|---|
| Best known for | The appearance of raised hypertrophic and keloid scars | Comfort, hydration and softness on settled marks |
| Evidence base | Strongest of the non-invasive options; first-line in guidelines | Valued cosmetically; no scar-specific clinical claims |
| How it works | Thin occlusive layer over the scar | Water-rich, soothing, hydrating plant gel |
| Feel | Film-like; some find it less pleasant on the face | Light, calming, slip-friendly for massage |
| Suits sensitive skin | Usually, though some get itching or dryness | Often a gentle choice; patch test first |
| Commitment | Daily use over weeks to months | Daily use over months; pairs with massage |
How to choose
A simple way to think about it:
- If your scar is raised, recent or post-surgical, silicone is the evidence-led starting point, ideally after a word with your surgeon, pharmacist or a healthcare professional.
- If your skin is sensitive and your priority is everyday comfort on an older, settled mark, an aloe-rich cream is a kind, gentle choice that is easy to keep up.
- If you like a routine, some people use silicone as the evidence-based step and aloe for comfort and massage at other times. If you combine products, introduce them one at a time.
Our Aloe Renew Scar Cream is our aloe-first option for that comfortable, sensitive-skin-friendly daily care, and you can see how it fits the broader range on our sensitive skin and aloe hub. Whatever you choose, the real secret is consistency over time rather than the product alone.
The honest bottom line
This is not a contest with a single winner. Silicone is the evidence-led choice for the appearance of raised scars; aloe is the gentle, comforting choice for everyday care of settled marks and for sensitive skin. Match the option to your scar, your skin and how likely you are to keep using it, and ask a healthcare professional about anything raised, painful or changing.
