Radiant Choice Vitamin C Face Serum
Lotus Herbals' entry into the Vitamin C serum category, part of the Radiant Choice range. The Vitamin C form used is not confirmed on public-facing product pages - key information for assessing formula stability in India's heat. The brightening complex combines Vitamin C with Turmeric Extract (Curcuma Longa), Saffron Extract, and Hyaluronic Acid. Curcumin in Turmeric has published brightening and anti-inflammatory data. Saffron Extract contains safranal and crocin with antioxidant and mild brightening properties. Contains synthetic fragrance. Full INCI is not published - active concentrations are not disclosed.

Turmeric's brightening and anti-inflammatory properties are well-aligned with Indian skin concerns and have strong cultural familiarity. The lack of disclosed Vitamin C form is a material gap - for India's climate, only heat-stable derivatives (EAA, Ascorbyl Glucoside) are appropriate. Users who react to fragrance should be cautious with leave-on serums.
This is a web evidence review, not a Clean Sheet certification. We checked the ingredient list, publicly available test reports, marketing claims, and formula logic using only public information available at the time of review.
At a glance
What was checked
Concern
What was checked
The Vitamin C form is not disclosed. Without knowing whether this is L-ascorbic acid, ascorbyl glucoside, ethyl ascorbic acid, or another derivative, efficacy and stability cannot be assessed. The claim cannot be independently evaluated.
Both ingredients have plausible brightening science at ingredient level, but concentrations are not disclosed and no finished-product efficacy data is published.
The breakdown
Public Evidence Score across 5 pillars. Open any row for the full rationale.
Ingredient SafetyFair
The Vitamin C form is not specified anywhere in public-facing documentation.
The Vitamin C form is not specified anywhere in public-facing documentation. If L-ascorbic acid is used, stability is a concern in India's heat - unstable L-AA degrades to dehydroascorbic acid and erythrulose, which can cause skin yellowing and irritation. If a stable derivative (EAA, Ascorbyl Glucoside) is used, this concern diminishes. Turmeric at rinse-off concentrations is safe; at high leave-on concentrations, photosensitivity has been reported in some individuals. Contains synthetic fragrance in a leave-on serum with no allergen breakdown - elevated sensitisation concern for regular facial use. Full INCI is not published, preventing a complete regulatory screen.
Formula LogicConcern

The Vitamin C form and concentration are not disclosed - this is the defining active in this serum, and without knowing the form (L-ascorbic acid vs stable derivative) formulation efficacy and stability cannot be assessed. Turmeric (Curcumin) and Saffron (Safranal, Crocin) have published brightening evidence but their concentrations are also undisclosed. The formula cannot be meaningfully evaluated as a Vitamin C serum without disclosure of the primary active's chemical identity. This is not a minor gap - for a product whose entire positioning is built on a single named active, not disclosing that active's form is a critical information failure.
Claims EvidenceConcern
The brand's hero active - Vitamin C - is not identified by form or concentration.
The brand's hero active - Vitamin C - is not identified by form or concentration. This is a fundamental transparency failure for a product sold as a 'Vitamin C Serum'. Form (stable vs unstable) and concentration are the two most important pieces of information for a consumer buying a Vitamin C product. Full INCI is not publicly available. No clinical substantiation for brightening claims. No anti-oxidant efficacy test result is published. The supporting botanical actives (Turmeric, Saffron) are listed but their concentrations are also not disclosed.
Test TransparencyGrade FConcern
No Vitamin C stability test, no brightening efficacy study, no clinical trial data, no independent safety assessment, and no preservative efficacy test result is publicly...
No Vitamin C stability test, no brightening efficacy study, no clinical trial data, no independent safety assessment, and no preservative efficacy test result is publicly accessible for this product. The marketing positions this as an active Vitamin C serum, but no test evidence of any kind is publicly provided to support that positioning.
Consumer ClarityConcern
Basic usage instructions are present.
Basic usage instructions are present. However, the Vitamin C form is not named - consumers cannot determine whether they are buying a stable or unstable formulation, which matters enormously for storage and efficacy in India's climate. No guidance on fragrance allergen risk. No clear indication of whether this is an AM or PM product, or whether additional SPF is required when using Vitamin C. No patch test guidance is provided for a leave-on active serum.

What would strengthen this review
Public evidence the brand could provide to close verification gaps
- ○Vitamin C INCI name (chemical form) is not disclosed anywhere on public documentation
- ○Vitamin C concentration is not disclosed
- ○Full INCI not publicly available
- ○No stability test data for the Vitamin C form at India storage temperatures
- ○No finished-product brightening efficacy study
- ○Fragrance allergen breakdown not published
- ○No independent safety assessment or preservative efficacy test publicly available
Selling a product as a 'Vitamin C Serum' without disclosing the Vitamin C form is a critical information gap. The form determines everything: stability, efficacy, appropriate pH, and storage conditions. For India's climate specifically, heat-unstable forms degrade rapidly and deliver no benefit. Until the Vitamin C form is publicly named, this product cannot be responsibly recommended as a Vitamin C serum.
