What you need to know
This is a serum with Ascorbic Acid 23.0%. An antioxidant (usually L-Ascorbic Acid) that neutralizes free radical damage from UV and pollution, brightens skin tone, and supports collagen synthesis.
Who should use this: If your concern is dull skin, hyperpigmentation, sun damage, or uneven tone, this ingredient addresses that directly. 10-20% for L-Ascorbic Acid. Below 8% may not be effective. Above 20% increases irritation without added benefit.
Where this goes wrong
L-Ascorbic Acid is unstable and oxidizes quickly (turns yellow/brown). If your serum has changed color, it has degraded. Can sting on broken or sensitized skin. Store in a cool, dark place.
This is a serum with Squalane. A lightweight, stable oil derived from squalene (naturally found in your skin's sebum). Mimics your skin's natural oils without clogging pores.
Who should use this: If your concern is dry skin, dehydrated skin, sensitive skin, or as an occlusive layer, this ingredient addresses that directly. 100% squalane oils are common. In formulations, any percentage works. It is a moisturizing ingredient, not a treatment active.
Where this goes wrong
Not an active ingredient. Does not treat any skin condition. It moisturizes. Some people with very oily, acne-prone skin may find it too heavy despite the 'non-comedogenic' claim. Patch test first.
This is a serum with Sodium Hyaluronate. A humectant that holds up to 1000x its weight in water. Draws moisture from the environment into your skin. Found naturally in your skin but declines with age.
Who should use this: If your concern is dehydrated skin, dry skin, fine lines from dehydration, or all skin types, this ingredient addresses that directly. 0.1-2%. Low molecular weight penetrates deeper. High molecular weight sits on top and plumps. Most products use a mix.
Where this goes wrong
In very dry climates with low humidity, HA can pull moisture OUT of your skin instead of from the air. Always seal it with a moisturizer. Not a treatment for any skin condition. It hydrates. That is all.
Our verdict
The Ordinary's Vitamin C Suspension 23% + HA Spheres 2% is a no-nonsense, potent L-ascorbic acid treatment. It delivers strong brightening results but comes with significant textural and tolerability challenges. This product is for experienced vitamin C users only.
Key ingredients
To mitigate some of the potential irritation and improve the feel, the formulation includes Squalane, a lightweight emollient that mimics the skin's natural oils. Squalane helps moisturize and provide an occlusive layer, which can be beneficial for dry or dehydrated skin. However, it is not an active ingredient that treats skin conditions; its role is purely moisturizing. The product also contains Sodium Hyaluronate, a form of hyaluronic acid, which helps draw moisture into the skin. While beneficial for hydration, the 'how this goes wrong' with hyaluronic acid is that in very dry environments or without an occlusive layer on top, it can sometimes pull moisture from deeper skin layers rather than the air, potentially leading to dryness for some.
Who should use this
This product is best suited for individuals with resilient skin who have extensive prior experience with vitamin C and are looking for maximum potency to address stubborn hyperpigmentation, dullness, and uneven skin tone. It could also work for those with dry or mature skin who tolerate high concentrations of actives well, given the inclusion of squalane and hyaluronic acid for hydration.
Who should skip this
Anyone new to vitamin C, those with sensitive skin, rosacea, or compromised skin barriers should absolutely skip this product. The high concentration of L-ascorbic acid and the gritty texture are likely to cause significant irritation, stinging, and redness. Pregnant women should consult their doctor before using any vitamin C product, and if they do, should stick to 100% mineral sunscreens for daily protection.
How to use
Apply a small pea-sized amount to clean, dry skin in the evening. Due to its heavy, gritty texture, it does not layer well under other products or makeup, making nighttime application preferable. Always ensure you are using a broad-spectrum sunscreen during the day when using vitamin C, even if applied at night. Remember, only one active per routine.
What users say
Based on existing feedback, users note the 23% L-ascorbic acid is a 'nuclear option' for vitamin C. The common sentiment highlights the high concentration, gritty and unpleasant texture, and potential stinging upon application. However, for those whose skin tolerates it, the brightening results are described as 'real'. The consensus recommends applying it at night due to the heavy texture and advises sensitive skin types or beginners to start with lower concentrations. There are currently 0 reviews available for this specific product.
Price context
At Rs800, this vitamin C serum offers exceptional value, characteristic of The Ordinary's pricing strategy. Similar high-potency L-ascorbic acid serums from other brands often cost significantly more, sometimes several times this price. While the texture and user experience may not be premium, the active ingredient delivery at this price point is unmatched, making it a highly accessible option for those seeking potent vitamin C on a budget.
Pros
- + Extremely high concentration of L-ascorbic acid for maximum potency.
- + Very effective for brightening skin and addressing hyperpigmentation.
- + Remarkably affordable, making high-strength vitamin C accessible.
- + Includes squalane and hyaluronic acid for some hydration.
- + No unnecessary fragrance or dyes.
Cons
- - Unpleasant, gritty texture that does not layer well.
- - High potential for stinging, irritation, and redness, especially for new users.
- - Not suitable for sensitive skin or vitamin C beginners.
- - Best used at night due to texture, limiting daytime antioxidant benefits.
Final take
This is a potent, no-frills vitamin C serum best reserved for seasoned active users with resilient skin. If you prioritize results and affordability over elegant texture and ease of use, and your skin can handle high concentrations, it's a solid choice. For everyone else, starting with a lower percentage vitamin C serum is a much safer and more comfortable introduction.
