Featured Ingredients
Regu-Stretch – The brand name for the proprietary blend in the Celtrixa formula. Hydroxatone says the blend is designed to prevent new stretch marks from forming while diminishing existing ones. No peer-reviewed clinical studies on the blend specifically have been published.
O.D.A. White – A skin-brightening complex marketed to lighten the appearance of darker stretch marks over a few weeks of use.
Palmitoyl Tripeptide-5 – A synthetic peptide also sold under the trade name Syn-Coll. It works in the same broad family as Matrixyl 3000, activating signaling pathways that prompt skin fibroblasts to produce new collagen.

Side Effects and Directions
People with sensitive skin should conduct a patch test before regular use to reduce the risk of an adverse reaction. Avoid contact with the eyes. If contact occurs, rinse thoroughly with cold water. The formula contains retinyl palmitate, a vitamin A derivative, so anyone pregnant or nursing should consult a doctor before use.
Apply twice daily. Massage a small amount of cream into the skin until the product is thoroughly absorbed.
In-Depth Review
Celtrixa Stretch Mark Lotion is formulated to reduce the appearance of stretch marks on the hips, thighs, stomach, and breasts. The product is manufactured by Hydroxatone, the same parent company behind the Hydroxatone anti-aging line. The marketing positions Celtrixa as both a treatment for existing marks and a preventive product for new ones.
The ingredient list includes several skin-supporting components. Shea butter is one of the most widely used emollients in body care, and works well in tandem with other natural ingredients for stretch marks such as cocoa butter and vitamin E. Sodium hyaluronate, the salt form of hyaluronic acid, provides hydration. Panthenol soothes irritated skin, and antioxidants like green tea extract and grape seed extract address inflammation.
The peptide story is more interesting and more limited at the same time. Palmitoyl Tripeptide-5 is a real, well-characterized cosmetic ingredient that has been shown in manufacturer-funded studies to stimulate collagen production. The relevant trials measured reductions in facial wrinkle appearance, not stretch marks, and independent replication in randomized placebo-controlled trials remains thin. The collagen-stimulating mechanism is plausible for stretch marks, since striae form when the dermis tears under rapid stretching, but plausibility isn’t the same as proven effect.
There’s a bigger issue with one of the brand’s central claims. The Mayo Clinic and the American Academy of Dermatology both state that no topical cream has been proven to prevent stretch marks. A Cochrane review covering multiple randomized controlled trials found no statistically significant difference in stretch mark development between women who used topical preparations with active ingredients and women who used placebo or no treatment. Celtrixa’s “prevents new stretch marks” claim does not have published evidence behind it. The product can hydrate skin and may improve the look of existing marks, but prevention is a stronger claim than the science supports.
It’s also worth knowing that Hydroxatone, the manufacturer, settled a class action lawsuit in 2013 over deceptive risk-free trial and auto-shipment billing practices that Celtrixa was named in. The settlement was about how the product was sold, not whether it worked, but anyone considering an online order should be cautious about subscription enrollments.
Who Celtrixa Is Best For
Celtrixa is most suitable for people with mild to moderate, newer stretch marks who want a hydrating, peptide-containing lotion to apply daily. Fresh red or purple marks generally respond better to topical treatment than older silvery ones, and Celtrixa’s emollient base plus collagen-supporting peptide is reasonable for that window.
People expecting full erasure of older, faded white stretch marks will likely be disappointed. Mature stretch marks are essentially scar tissue, and topical products of any brand have limited effect on them. Anyone with extensive or deeply pigmented marks should consider in-office options like laser treatment or microneedling, which have stronger clinical support.
Pregnant or nursing women should not use Celtrixa without checking with a healthcare provider, since the formula contains retinyl palmitate. Anyone shopping specifically for how to clear pregnancy stretch marks is generally better served by a maternity-formulated product designed without retinoids.
How to Use Celtrixa for Best Results
Twice-daily application is the brand’s standard direction, and consistency matters more than quantity. A pea-sized amount massaged into clean skin twice a day, every day, is the realistic minimum to expect any benefit. Peptides are slow-acting compared to retinoids or exfoliants, and visible changes from this kind of formula tend to show up around the 8 to 12 week mark, not within days.
Pair Celtrixa with broader skin habits to give the formula the best chance of working. Drinking enough water keeps skin pliable, and a diet that includes the right ingredients for fading stretch marks from the inside, such as vitamin C and zinc, supports collagen production. Avoid harsh exfoliants on the same skin area while using Celtrixa, since the lotion isn’t designed for irritated or compromised skin.
Older stretch marks are notoriously harder to shift than newer ones, which is why most methods for getting rid of stretch marks work best when started early.
Is Celtrixa Worth It?
Celtrixa sits in an awkward middle ground. The formula isn’t bad. It includes hydrating ingredients, a credible collagen-stimulating peptide, and antioxidants. But the price point is high relative to drugstore competitors that offer similar ingredient profiles, and the absence of published clinical data specifically on Celtrixa weakens its case.
Bio Oil and TriLastin-SR are two more established options in this category. The Bio Oil review covers an inexpensive oil-based formula with a long track record, while TriLastin-SR is positioned in the same premium tier as Celtrixa but with more visible third-party reviewer support.
For a final shortlist, our roundup of the best stretch mark creams compares Celtrixa against its main alternatives by price, ingredients, and reported outcomes. Celtrixa is worth trying if you want a peptide-based lotion and aren’t expecting miracle results, but cheaper formulas with similar ingredient lists are easy to find.
