Stretch Mark Concentrate, editorial
30ml. Six weeks of focused use. A bottle designed to finish its job.

The formulation

A serum, not a cream.

The collagen damage that creates a stretch mark is concentrated in a band millimetres wide. The formula that addresses it should be too, not a body lotion with a marketing claim.

Four months at our London lab to land 5% niacinamide and 3% centella in a near-anhydrous gel. The actives stay potent on the shelf, absorb in seconds when pressed in.

What's in it, and why.

Four ingredients carry the work. The supporting cast keeps the texture light and the formula stable.

Centella asiatica 3%

Triggers fibroblast activity, the cells that rebuild collagen, in stretch-marked skin. Clinically studied on pregnancy stretch marks since the 1970s. Doesn't cover the damage; it rewrites it.

Niacinamide 5%

Higher-dose Vitamin B3 to fade the hyperpigmentation that gives fresh stretch marks their violet colour. The doctor-grade concentration for post-partum tone correction.

Bakuchiol

A pregnancy-safe retinol analogue extracted from Babchi seeds. Drives cell turnover and supports collagen without the irritation, photosensitivity or pregnancy contra-indication of retinol.

Rosehip CO2

A trans-retinoic acid precursor cold-pressed under CO2 (preserves the actives). The orange colour you see in the bottle is the carotenoid content, over 60 mg/100g.

The ritual

How to use.

3-4 drops, pressed directly into targeted stretch marks twice daily, morning after the shower, evening before bed. Layer the Firming Body Cream on top once fully absorbed (about 60 seconds). Twelve-week protocol for visible fade. Bottle holds about six weeks of targeted application.

Stretch Mark Concentrate, ingredients and composition

Three ingredients, three roles

Centella. Niacinamide. Bakuchiol. Each one carries a specific job in the formula.

The protocol

Twelve weeks. Three milestones.

A targeted serum works on a clock. These are the markers our trial participants reported, week by week.

Week

04

Colour begins to shift.

Violet stretch marks soften towards pink. Niacinamide is doing the pigment work first.

Week

08

Texture starts to flatten.

Centella drives the collagen rebuild. 67% of trial participants report visible softening at this mark.

Week

12

Trial threshold.

41% of participants report measurable fade on silver marks, the category the literature considers near-impossible to shift.

I work in cosmetic R&D and ordered with low expectations because the post-partum category is mostly relabelled body lotions. The INCI here is the real story. 5% niacinamide without the usual fillers, centella at a meaningful dose, bakuchiol instead of retinol (the correct call for this use case). Works on its own science.

I used Augustinus Bader Body for two years and was loyal. A friend made me try this on one hip while she watched. Eight weeks later the TOC side was visibly winning. I am furious. Ordering another bottle.

The formula works, no question. Used twice daily for 10 weeks and the colour and texture have shifted on the worst lines. Only feedback: the dropper cap is fiddly with wet hands, which is most of the time post-partum. Half a star off.

Second pregnancy stretch marks at the start of the third trimester. Nothing worked the first time around so I had low hopes. Used this from week 28 daily and the new lines are already much lighter at 6 weeks post-partum than the older ones from baby 1. Genuine difference.

I review beauty for a living and I'm hard to impress. The dosing here is honest, the bakuchiol choice is clinically smart, and there's no Vaseline-style padding in the INCI. Most post-partum products are scam-adjacent. This isn't.

Effective on fresh marks (mine at 4 months post-partum). Less dramatic on the older marks from my first pregnancy three years ago, but still some softening at the edges. The 12-week timeline is honest. Not a miracle product, but more than a placebo.

I'm a photographer, my partner shoots me in studio twice a year for our anniversary. Last set he asked if I'd had something done because the texture difference on my hips was visible. Just twelve weeks of this serum, nightly. Worth the spend.

Recommended by my GP after she used it herself. The bakuchiol decision is what makes this work during nursing, when retinol is off the table. Used twice daily for ten weeks, real change on fresh marks, modest change on older ones. Honest product.

Worked best on my belly stretch marks. Less effective on the older lines along my hip from my first pregnancy four years ago, but those did soften at the edges. Patience matters. The 12-week protocol isn't a marketing slogan.

The Cut

Asked & answered.

Will it fade silver stretch marks?

Silver marks are mature scar tissue, harder to shift than violet/fresh marks. 41% of trial participants saw meaningful change on silver marks over 12 weeks; 67% saw it on violet marks. Be realistic: this is a softening, not an erasure.

Pregnancy-safe?

Bakuchiol replaces retinol so the formula is technically safe through pregnancy. But concentrated actives at this dose are typically used post-partum, when the body has stopped stretching, speak with your midwife if you want to start during pregnancy.

Can I use it alongside Firming Body Cream?

Yes, concentrate first, twice daily on the targeted lines. Layer the cream all over once the serum has absorbed. The two are designed to work together: serum treats, cream supports.

How long until I see something?

Most users notice a softening in colour around week four, and a flattening in texture around week eight. The 12-week protocol is the threshold for the trial data we publish.

Can I use it on a c-section scar?

Once the scar is fully closed and your obstetrician has cleared topical products (typically 6-8 weeks post-op), yes. Many of our customers use it on c-section scars with good results.
