The Deconstruct Face Serum is a water-based Vitamin C treatment formulated to brighten skin, fade dark spots, and support collagen synthesis.

The formula centres on 3-O-Ethyl Ascorbic Acid at 10% concentration, a stable Vitamin C derivative that targets brightening, pigmentation, and collagen synthesis. Paired with 0.5% Ferulic Acid, the formula gains dual benefits: Ferulic Acid stabilises the Vitamin C, extending its potency, and adds direct antioxidant protection against UV-related damage. Hyaluronic Acid completes the active lineup, drawing moisture into the skin for a hydrating finish without heaviness. The serum runs at a pH of 3 to 4, which supports effective Vitamin C absorption. It is water-based, non-sticky, and fragrance-free, and carries vegan and cruelty-free certifications.
This serum suits all skin types, from oily and combination to dry, normal, and sensitive. Reviewers with sensitive and acne-prone skin report using it without irritation or breakouts, and the 10% Vitamin C concentration makes it a reasonable starting point for those new to active ingredients. However, a small number of users have experienced adverse reactions, including cystic acne, inflammation, and redness. These experiences are in the minority but are genuine and worth noting. If you have reactive skin, patch-test before full-face application. Some buyers have also flagged that the bottle size feels limited for the price, so evaluate the 10ml, 20ml, and 30ml options based on your usage needs.
At ₹279 to ₹1198 across 12 sellers, the Deconstruct Face Serum delivers strong value for a stabilised, targeted Vitamin C formulation that works in both morning and evening routines.

A small number of users have reported adverse reactions including cystic acne, so run a patch test before full-face application.
Ferulic Acid is a plant-derived antioxidant included at 0.5% in this formula.

This combination supports a brighter, more even-toned complexion with consistent use.
Reviewers report a noticeable brightening and evening of skin tone within a few weeks of consistent use. Some users describe an immediate luminosity after application. Fading of dark spots and pigmentation requires sustained use over a longer period, and individual results depend on skin type and sun protection habits.

The product highlights describe the 10% Vitamin C concentration as gentler than higher concentrations. However, a small number of users have experienced redness and inflammation, so run a patch test on a small area before full-face use.
Basic Vitamin C products often rely on simpler formulations without stabilising agents. This serum pairs 3-O-Ethyl Ascorbic Acid with 0.5% Ferulic Acid, which stabilises the Vitamin C and enhances its effectiveness, and adds Hyaluronic Acid for hydration. The formulation runs at a pH of 3 to 4, the effective range for Vitamin C absorption.
This serum is available across 12 sellers, with prices starting from ₹279. Check platforms like Amazon India, Flipkart, and Nykaa to compare current prices and available sizes. The 30ml option typically offers better value per millilitre compared to the 10ml size.

The 10% concentration is an accessible level for daily use, particularly for those new to Vitamin C actives. Ferulic Acid in the formula helps stabilise the Vitamin C and supports its effectiveness. If you are new to active ingredients, start with once-daily application and monitor your skin's response before moving to twice daily.
Vitamin C plays a direct role in collagen biosynthesis, which the product highlights as a key benefit of this formula. The active form used here, 3-O-Ethyl Ascorbic Acid, targets this function alongside brightening and antioxidant protection. Consistent daily use over several weeks supports the longer-term effects on skin firmness and radiance.
