In briefChecked October 2026
Total Curve pairs a daily herbal capsule containing phytoestrogens with a topical gel made with Volufiline, a cosmetic ingredient, and is sold as a breast enhancement system. Total Curve itself hasn't been trialed. Its 'up to 8.4%' claim traces back to an unpublished supplier study of the gel ingredient alone, and the hormone-active herbs in the capsule aren't right for everyone. A money-back guarantee runs 67 days from delivery, with strict conditions.
Total Curve suits women who are curious about a non-surgical breast enhancement product, accept that the evidence is thin and plan to use the refund policy if needed. The 'up to 8.4%' claim rests on an unpublished study of the gel ingredient, not of Total Curve, and the hormone-active herbs in the capsules aren't suitable for everyone.
This review looks at the contents of Total Curve, what the evidence really shows, the side effects and the guarantee terms. We'd suggest reading all of it before you make up your mind.
Total Curve Summary Table
Ingredients
A phytoestrogen herb capsule and a gel containing Volufiline. The page gives no amounts, serving size or concentration.
Evidence
The product hasn't been trialed. The Volufiline figure is from an unpublished supplier study.
Transparency
The maker and refund terms are clear, and there's no autoship. But there are no doses, directions or study sponsor, and the page makes an unsupported claim of being free of side effects.
Safety
Several herbs act on hormones. Black cohosh carries a rare risk of liver injury and dong quai a risk of bleeding. The page lists no warnings.
Value
Around $69 (October 2026), for a product without reliable evidence behind its main claim.
Each product is judged on ingredients and doses, published evidence, openness about the formula, guarantee terms, safety and value. Our review process
What Is Total Curve?
Leading Edge Health sells Total Curve as a 'Daily Breast Enhancement Therapy'. One half is a daily herbal supplement made from buckwheat, fennel, dong quai, damiana, blessed thistle, hops, watercress, black cohosh and wild yam. The other is a lifting and firming gel with Volufiline, which appears in the gel only. The page doesn't state amounts, a serving size, how much Volufiline is used or how to take it.
*The capsules are a dietary supplement and the gel is a topical cosmetic. Not intended to diagnose, treat, cure or prevent any disease. Statements not evaluated by the FDA.
Active Ingredients, One by One
Below, each listed ingredient is explained along with what human studies have examined. When the maker doesn't disclose doses, we can't tell whether they match the studies:
Volufiline (gel only)Cosmetic Ingredient
A plant-derived cosmetic ingredient, present only in the gel and at an undisclosed level. The claim about fat cells comes from a lab cell test. In people, the only data is an unpublished supplier study of 32 women, with no control group described.
Buckwheat Leaf and FlowerSupplement Herb
Nothing shows buckwheat affects hormones or the breasts.
The daily supplement also holds fennel seed, dong quai root, damiana leaf, blessed thistle, hops, watercress, black cohosh and wild yam. Some are sold for estrogen-like activity, yet no human evidence shows these herbs make breasts larger. Black cohosh has been linked to rare cases of liver injury, and dong quai may raise bleeding risk when combined with blood thinners.
Where we have reservations
For balance, these are the weaknesses of Total Curve that buyers should know about:
→No trial of this product sets a timeline, so the guarantee window (67 days from delivery) is the practical limit for deciding
→Responses differ a lot from person to person, and not everyone gets the same benefit
→Nothing in the guarantee terms says purchases from other sellers are covered
When Results Might Show Up
No study of Total Curve has tracked results across time. Here is what we do and don't know, and results differ from person to person:
1
Months 1–2: Nothing to Go On
Since no study has measured results for Total Curve, we have no dependable timing information. The sales page mentions a Volufiline study lasting 56 days, but it tested only the gel ingredient and has not been published.
2
Day 67: Last Day for Returns
Nothing suggests that using the two parts together works. To qualify for a refund, returns have to arrive within 67 days of delivery.
⚠️ Please note: Responses vary. This section covers what has and hasn't been measured, and it isn't a promise. The 67-day money-back guarantee lets you try the product, but conditions apply (see below). To keep the refund option open, decide by about day 55 so returns arrive within 67 days of delivery.
What the research says
Trial of the product itself: None has been published.
Ingredients: The sales page describes a Volufiline study of 32 women aged 18–35 who put it on one breast twice a day for 56 days, reporting breast tissue up 'by up to 8.4%'. It leaves out who ran the study, how tissue was measured, whether a control group existed and whether the results were significant. We found no peer-reviewed publication, and it looks like ingredient-supplier data. The '492% more fat' figure comes from a cell culture test. No human evidence shows that the oral phytoestrogen herbs increase breast size.
Label doses: The page gives no amounts, serving size, Volufiline concentration or directions.
Guarantee: 67 days from delivery. Try the product for 60 days, then send back the containers (empty ones, or unopened ones along with the first two opened) so they arrive within 67 days of delivery. Shipping isn't refunded, you pay the return postage, and each customer gets one refund.
✓ A 67-day (from delivery) money-back guarantee, with no autoship
✓A non-invasive option for anyone wanting to try something before looking at medical routes
Considerations
✗Total Curve hasn't been trialed, and the Volufiline data is unpublished supplier data
✗'Up to 8.4%' is a best-case number from 32 women, with no control group described
✗The hormone-active herbs, including black cohosh and dong quai, come with genuine cautions
✗Doses, serving size and directions are missing from the product page
Who Should Avoid Total Curve
✗Anyone younger than 18
✗Women who are pregnant or breastfeeding
✗Women with a hormone-sensitive cancer, endometriosis or fibroids, or who use hormone therapy or birth control (hops, fennel, dong quai, black cohosh and wild yam are sold for estrogen-like activity)
✗People with liver disease (black cohosh)
✗People taking blood thinners such as warfarin (dong quai)
This list is not exhaustive. Ask a doctor or pharmacist before you take any supplement.
Is Total Curve Safe to Use?
The finished product has no published safety study. Meanwhile, the sales page says it is free of side effects and lists no warnings. The daily supplement includes several hormone-active herbs, plus black cohosh (tied to rare but serious liver injury) and dong quai (which may raise bleeding risk).
What Is Known
Dark urine, yellowing skin or pain in the upper right of the abdomen can signal liver injury. If you notice any of them, stop taking it and see a doctor. Patch-test the gel first.
Talk to your doctor first if:
● You use blood thinners such as warfarin
● You use hormone therapy or hormonal birth control
● You have endometriosis, fibroids or another hormone-sensitive condition
● You have liver disease
● You are pregnant or breastfeeding

Our Final Verdict on Total Curve
Women who are curious about a non-surgical breast enhancement product, accept the thin evidence and will use the refund policy are the audience here. The 'up to 8.4%' claim comes from an unpublished study of the gel ingredient rather than of Total Curve, and the hormone-active herbs in the capsules don't suit everyone.
A fit for: women who are curious about a non-surgical breast enhancement product, accept that the evidence is thin and are prepared to use the refund policy.
Not a fit for: anyone with a hormone-sensitive condition or liver disease, anyone on blood thinners, hormone therapy or birth control, and anyone who expects a measurable size change.
*Results may differ between people. These statements have not been evaluated by the FDA. Not intended to diagnose, treat, cure or prevent any disease. Read the full disclaimer
The maker sells the two as a pair. However, nobody has studied Total Curve or the two parts used together, and neither part has published evidence for increasing breast size. The capsule's hormone-active herbs bring cautions that the gel doesn't.
No safety study of Total Curve has been published, and the sales page lists no warnings. The daily supplement has black cohosh (rare reports of liver injury), dong quai (may add to bleeding with blood thinners) and several herbs sold for estrogen-like activity. Speak with your doctor first, particularly if you use prescription medication or birth control.
Buy from the official website, where the 67-day guarantee clearly applies. Returns must arrive within 67 days of delivery. Shipping isn't refunded, you pay the return postage, and each customer gets one refund.
Without a doctor's OK, it isn't for people under 18, those who are pregnant or breastfeeding, anyone with a hormone-sensitive cancer, endometriosis or fibroids, anyone on hormone therapy or birth control, anyone with liver disease, or anyone taking blood thinners such as warfarin.
