5 Best Old Scar Removal Cream | What Old Scars Really Respond To

The clear, odorless gel built to vanish under makeup and sunscreen

A visible old scar — on a jawline, an eyelid, the back of a hand — is where a clear gel beats an oil. RejuvaSil is 97% liquid silicone, a gel that dries into a thin, flexible layer rather than a cream you can feel sitting there. That layer is what holds moisture against the scar so it can soften and flatten over time.

Unlike the Bio-Oil above, which you massage into large areas, this 15ml gel is designed to be worn discreetly. The maker blends liquid silicone with Vitamin C (an antioxidant) and Squalane (a moisturizing oil your skin already makes), and it dries quickly, clear, and odorless. It is water-resistant and thin enough to wear invisibly under makeup or sunscreen without clogging pores. It is also hypoallergenic, fragrance-free, and paraben-free — useful if scented products set your skin off. What people praise most is how comfortably it wears through a full day.

Customers note eyelid-incision scars looking less red and less raised after about a week and a half of twice-daily use. The catch is size: 15ml covers a small mark, not a long one. For a compact, visible old scar you can dress twice daily, this gel does its job — and it hides better than the Xeragel below, which runs shiny.

100% silicone in a compact tube made for exposed scars

Xeragel keeps it to one ingredient: a 100% silicone formula with no added fragrance, made in the USA. It forms a moisture-locking barrier over the scar to support smoother, softer texture over time. The 10g tube is compact and portable, aimed at exposed scars — face, neck, hands, elbows — the spots where silicone sheets are awkward to keep in place.

Two things separate it from the RejuvaSil gel above. First, it’s fragrance-free and hypoallergenic, so it suits sensitive skin and works for adults and children alike. Second, the maker states each 10g tube lasts up to 30 days on a 3 to 4-inch scar. That’s a useful benchmark for a small mark, but watch it: a 15-inch surgical scar will drain that tube much faster, closer to a week.

The honest gripe here is texture. The gel runs sticky and looks shiny on the skin, which is noticeable over a scar under the eye — though you can cover it with makeup. Results vary by scar type, too: one buyer reports a raised nose-piercing scar flattening within days, while a breast surgery scar faded over a month. That uneven record is the real story — it works well on some scars and not others, so a long surgical line is a poor fit here.

The scar cream that fights the sun at the same time

Old scars don’t only raise and thicken — they also darken, because sun exposure pushes pigment into tissue that has already been through trauma. NewGel+ handles both jobs in one daily dot. It pairs 100% Medical Grade Silicone with Zinc Oxide (a mineral sunscreen ingredient) at broad-spectrum SPF 30, so the dot that softens the scar also helps keep it from tanning darker than the skin around it. For arms, hands, and face, that pairing is tough to top — and it is the one pick here with any sun protection at all.

The scar base is the same as the original NewGel+, just with UV protection added. The maker lists silicone as the #1 ingredient recommended by scar experts, and NewGel+ is made by New Medical Technology, Inc. Per the maker, it’s scentless, non-toxic, and free of parabens, fragrances, and preservatives, plus gluten-free and non-comedogenic. Buyers reward the sunscreen angle most on exposed scars — a decided edge when your scar lives where the sun hits daily.

Fresh facial incisions are where it shines: the silicone sunblock goes on smooth rather than tacky, and while the zinc leaves a slight opaqueness, that’s easily concealed. Old scars are trickier. The maker’s own reviewers point out it’s best for new scars and largely untested on older ones. A dog-bite scar on the lip reportedly lightened and flattened over months of daily use with massage. The recurring caveat is the small 0.5 oz tube — it does the job, but you’ll reorder. If your scar sits under clothing, skip this one; you’d pay for SPF you never use.

The growth-factor cream aimed at small surgical scars less than an inch

Skinuva is the outlier on this list: it isn’t silicone-first. It’s built on a patented formula with selective Growth Factors (proteins meant to support collagen production, the scaffolding that keeps skin firm), blended with hyaluronic acid, aloe, centella asiatica, vitamin C, and silicone cream. The 0.5 oz size is explicitly for smaller scars under 1 inch — biopsy, skin cancer, arthroscopic, or laparoscopic incisions.

Its target is what separates it from every silicone gel here. Where RejuvaSil and Xeragel cover a scar in a moisture barrier, Skinuva is designed to work on the tissue itself. It’s fragrance-free and non-greasy, absorbing quickly without residue, so it’s easy to keep up twice a day, morning and night, on clean, dry skin — the routine the maker recommends for at least 3 to 6 months.

The catch is cost-to-size. Value for money comes up often among buyers, because a 0.5 oz tube empties quickly when you apply twice daily for months. It also isn’t built for large areas — match it to a mark under 1 inch or you’ll be reapplying constantly. Shoppers say marks fading and tapering toward a thinner line with consistent use. For a settled, small old scar that has refused to fade, this packs the most into the tube — assuming your scar is the right size for it.
