Total Curve is a breast enhancement system: a daily phytoestrogen herb supplement plus a topical gel with the cosmetic ingredient Volufiline. There's no trial of Total Curve. The 'up to 8.4%' claim comes from an unpublished supplier study of the gel ingredient alone, and the pill's hormone-active herbs aren't suitable for everyone. It comes with a 67-day (from delivery) money-back guarantee with strict conditions.
Total Curve is for women curious about a non-surgical breast enhancement product who accept that the evidence is thin and are ready to use the refund policy. The 'up to 8.4%' claim comes from an unpublished study of the gel ingredient, not of Total Curve, and the pill's hormone-active herbs aren't suitable for everyone.
In this review we go through what's in Total Curve, what the evidence actually shows, the side effects and the guarantee terms. Read the full analysis below before making a decision.

What Is Total Curve?
Total Curve is sold by Leading Edge Health as a 'Daily Breast Enhancement Therapy'. It pairs a daily herbal supplement (buckwheat, fennel, dong quai, damiana, blessed thistle, hops, watercress, black cohosh and wild yam) with a lifting and firming gel containing Volufiline. Volufiline is in the gel only. No amounts, serving size, Volufiline concentration or directions are given.
*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 — Full Scientific Breakdown
What each listed ingredient is and what human studies have looked at. Where the maker doesn't disclose doses, we can't say whether they match the studies:
Volufiline (gel only)Cosmetic Ingredient
Cosmetic plant ingredient used in the gel only, at an undisclosed concentration. Its fat-cell effects come from a lab cell test, and the human data is an unpublished 32-woman supplier study with no described control group.
Buckwheat Leaf and FlowerSupplement Herb
Buckwheat has no evidence for hormonal or breast effects.
Also in the daily supplement: fennel seed, dong quai root, damiana leaf, blessed thistle, hops, watercress, black cohosh and wild yam. Several are marketed for estrogen-like activity, but there's no human evidence that these herbs increase breast size. Black cohosh has rare liver injury reports, and dong quai may increase bleeding risk with blood thinners.
📋 Our Editorial Concerns
In the interest of balance, here are the limitations of Total Curve that we think buyers should know:
→No trial of this product sets a timeline; the guarantee window (67 days from delivery) is the practical limit for deciding
→Individual response varies significantly — not everyone experiences the same benefit
→No doses, serving size, Volufiline concentration or directions on the product page
→The guarantee terms don't say they cover purchases from other sellers
Results Timeline: What to Expect
No study of Total Curve has measured results over time. Here's what is and isn't known. Individual results vary:
1
Months 1–2: No Data
No study of Total Curve has measured results, so there's no reliable data on timing. The Volufiline study described on the sales page ran for 56 days, but it tested the gel ingredient alone and hasn't been published.
2
Day 67: Guarantee Deadline
There's no evidence that using both parts together works. Returns must arrive within 67 days of delivery to qualify for a refund.
⚠️ Important: Response varies. This section describes what has and hasn't been measured, not a promise. The 67-day money-back guarantee lets you try it, but conditions apply (see below). To keep the refund option, decide by about day 55 so returns arrive within 67 days of delivery.
🔬 What the Evidence Actually Shows
Trial of the product itself: None published.
Ingredients: The sales page describes a Volufiline study in 32 women aged 18–35 who applied it to one breast twice daily for 56 days, with breast tissue up 'by up to 8.4%'. It doesn't say who ran it, how tissue was measured, whether there was a control group or whether results were significant, and we found no peer-reviewed publication; it appears to be ingredient-supplier data. The '492% more fat' figure is from a cell culture test. There's no human evidence that the oral phytoestrogen herbs increase breast size.
Doses on the label: No amounts, serving size, Volufiline concentration or directions are given.
Guarantee: 67 days from delivery. Try it for 60 days, then return the containers (empty ones, or unopened ones sent back with the first two opened) so they arrive within 67 days of delivery. Shipping isn't refunded, you pay return postage, and it's one refund per customer.
✓67-day (from delivery) money-back guarantee; no autoship
✓Non-invasive alternative for people who want to experiment before considering anything medical
✗ Considerations
✗No trial of Total Curve; Volufiline data is unpublished supplier data
✗'Up to 8.4%' is a best-case figure from 32 women with no control group described
✗Hormone-active herbs, black cohosh and dong quai carry real cautions
✗No doses, serving size or directions on the product page
⚠️ Who Should NOT Take Total Curve
✗Anyone under 18 years of age
✗Pregnant or breastfeeding women
✗Anyone with a hormone-sensitive cancer, endometriosis or fibroids, or on hormone therapy or birth control (hops, fennel, dong quai, black cohosh and wild yam are marketed for estrogen-like activity)
✗Anyone with liver disease (black cohosh)
✗Anyone on blood thinners such as warfarin (dong quai)
This list isn't complete. Check with a doctor or pharmacist before taking any supplement.
Is Total Curve Safe?
No safety study of Total Curve as a finished product has been published, and the sales page claims it is free of side effects and gives no warnings. The daily supplement contains several hormone-active herbs, black cohosh (linked to rare but serious liver injury) and dong quai (may increase bleeding risk).

🛡️ Final Verdict: Total Curve
Total Curve is for women curious about a non-surgical breast enhancement product who accept that the evidence is thin and are ready to use the refund policy. The 'up to 8.4%' claim comes from an unpublished study of the gel ingredient, not of Total Curve, and the pill's hormone-active herbs aren't suitable for everyone.
Best for: women curious about a non-surgical breast enhancement product who accept that the evidence is thin and are ready to use the refund policy.
Not for: anyone with a hormone-sensitive condition, liver disease, or on blood thinners, hormone therapy or birth control, or expecting a measurable size change.
*These statements have not been evaluated by the FDA. Not intended to diagnose, treat, cure or prevent any disease. Individual results may vary. Full disclaimer →
The maker sells them as a pair, but no study has evaluated Total Curve or the two parts together, and neither part has published evidence of increasing breast size. The pill's hormone-active herbs carry cautions that the gel doesn't.
No safety study of Total Curve has been published, and the sales page gives no warnings. The daily supplement contains black cohosh (rare liver injury reports), dong quai (may increase bleeding with blood thinners) and several herbs marketed for estrogen-like activity. Check with your doctor first, especially if you take 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 return postage, and it's one refund per customer.
Anyone under 18; anyone pregnant or breastfeeding; anyone with a hormone-sensitive cancer, endometriosis or fibroids, or on hormone therapy or birth control; anyone with liver disease; and anyone on blood thinners such as warfarin should not take it without a doctor's OK.
