FAQs
Q1. What is Ascorbyl Glucoside in ISIS Pharma Neotone Radiance SPF 50+ and why is this form of Vitamin C used in a sunscreen?
A1. Ascorbyl Glucoside is a Vitamin C derivative in which glucose is bonded to ascorbic acid — a molecular structure that dramatically improves stability. Pure ascorbic acid (L-ascorbic acid) oxidises rapidly in water-based formulas exposed to light, turning orange/brown and losing efficacy within weeks. Ascorbyl Glucoside is water-stable, colourless, and does not degrade under UV exposure — making it the preferred Vitamin C form for SPF products. In the skin, skin enzymes (glucosidase) cleave the glucose molecule to release active ascorbic acid gradually, providing sustained antioxidant and brightening activity throughout the day alongside the sun protection.
Q2. Does ISIS Pharma Neotone Radiance SPF 50+ replace both a brightening serum and a sunscreen?
A2. For daily urban use, yes — Neotone Radiance combines SPF 50+ broad-spectrum sun protection, a Niacinamide + Licorice depigmenting complex, Ascorbyl Glucoside antioxidant and brightening action, and a tinted finish in a single product. This makes it a highly practical daily product for Indian skin with hyperpigmentation concerns — one step delivers UV protection (preventing new pigmentation), active brightening (reducing existing pigmentation), antioxidant defence (protecting against pollution-induced free radicals), and a degree of colour correction. For intensive brightening, a dedicated night-time depigmenting serum can supplement it.
Q3. What shade is the tinted finish of Neotone Radiance SPF 50+, and will it suit darker Indian skin tones?
A3. Neotone Radiance has a universal adapting light tint designed to blend across a range of skin tones. It is not a deep shade-matched foundation tint — it provides a general evening effect on lighter to medium Indian complexions. For darker skin tones (Fitzpatrick V–VI), the tint may leave a slightly ashy or grey tone that requires blending. Testing on the jawline before committing to full-face use helps establish whether the tint complements your specific tone. The depigmenting and UV protection benefits apply equally regardless of the tint outcome.
Q4. Is ISIS Pharma Neotone Radiance SPF 50+ suitable for melasma-prone skin?
A4. Yes — it is one of the more comprehensively appropriate SPF products for melasma management. UV protection is mandatory for melasma (UV is the primary trigger for melanin overproduction in affected skin). Niacinamide and Licorice Extract address melanin transfer inhibition. Ascorbyl Glucoside adds antioxidant neutralisation of free-radical-mediated melanin stimulation. This multi-pathway approach to pigmentation prevention makes Neotone Radiance particularly suitable as the daily morning product in a melasma treatment protocol. Use alongside a dermatologist-prescribed depigmenting treatment at night for best results.
Q5. Can ISIS Pharma Neotone Radiance SPF 50+ be combined with Neotone Lightening Eye Contour for a complete routine?
A5. Yes — these two products are designed to work together as a complementary brightening and protective routine. Apply Neotone Radiance SPF 50+ over the face and neck as the morning step. Apply Neotone Lightening Eye Contour Care specifically to the periorbital (under-eye and orbital) area before or after the facial application. The Eye Contour's Caffeine, Hyaluronic Acid, and brightening actives address the specific under-eye concerns (dark circles, puffiness, fine lines) that Neotone Radiance is not specifically formulated to target.
