The Dot & Key 10% Niacinamide + Super Cica Face Serum addresses dark spots, acne scars, excess oil, and skin inflammation within a single formula.

Five actives define this formula. Niacinamide at 10% forms the core, supporting oil regulation, skin brightening, and reduction of dark spots and pore appearance. Cica brings anti-inflammatory action that calms redness and soothes acne-prone skin. Tranexamic Acid and Alpha Arbutin work together to fade hyperpigmentation and lighten post-acne marks. Oatmeal contributes soothing and barrier-supporting properties. The serum carries a fragrance-free, non-comedogenic formulation and holds a cruelty-free certification.
Oily, combination, and acne-prone skin types benefit most from this serum. Consistent users with these skin types report improved oil control, fewer active breakouts, and visible fading of post-acne marks within a few weeks of regular use. Sensitive skin users also report calming and barrier improvement. However, some reviewers experienced irritation or new breakouts after starting, so a patch test before full application is advisable, particularly for reactive skin. A small number of users noted the formula foams slightly on application, and some reported no significant change in dark spots despite consistent use. Individual results vary.

Apply 3-4 drops on clean skin and massage gently until it fully absorbs. You can use it twice daily, morning and night, as Dot & Key formulated it for day and night use. In the morning, follow with a moisturiser and sunscreen to complete your routine.
This serum contains 10% niacinamide, the concentration listed in the product specifications. At this level, niacinamide supports oil control, skin brightening, and reduction of dark spots and uneven skin tone. Reviewers report visible improvements in texture and glow with consistent use over several weeks.
Dot & Key formulated this serum for both day and night use. Niacinamide does not increase photosensitivity, so morning application suits daily use as long as you follow with sunscreen. Using it both morning and night allows for more consistent exposure to the actives across the day.
The serum lists sensitive skin as a compatible skin type in its specifications, and some sensitive skin users report positive results, particularly around calming redness and improving barrier function. However, some reviewers with reactive skin experienced irritation or new breakouts after starting. A patch test before full application is strongly advisable for sensitive skin types.
Results vary between users. Some reviewers report improvements in dark spots and acne marks within a week of starting. Others describe more gradual progress over several weeks of consistent use. For a realistic benchmark, give the serum at least four weeks of regular application before assessing its impact on pigmentation and oil control.
Purging refers to accelerated cell turnover that surfaces existing congestion faster than usual. This serum contains niacinamide, which does not typically trigger purging. If new breakouts appear after starting, they are more likely a sign of irritation or sensitivity to one of the actives. A patch test and a gradual introduction can help you identify your skin's response before committing to full-face use.
The 10% niacinamide in the formula helps regulate sebum production, which is one of niacinamide's well-documented functions in topical skincare. Reviewers with oily skin report a reduction in shine and excess oil throughout the day with consistent use. The watery, non-comedogenic base also avoids adding any heaviness or greasiness to the skin.
Reviewers describe the texture as watery and lightweight, with a fast-absorbing consistency that leaves no stickiness or heaviness. It delivers a matte finish, which suits oily and combination skin types well. Some users note that the serum foams slightly on application, which is worth knowing before first use.
Flash AI lists this serum from ₹383 across 13 sellers. Comparing prices on platforms like Amazon India, Flipkart, and Nykaa before purchasing gives you the best chance of securing it at the lower end of the ₹383 to ₹611 price range. Prices can shift by seller and pack size, so checking multiple listings is worthwhile.
The serum contains niacinamide, Cica, Tranexamic Acid, Alpha Arbutin, and Oatmeal, all of which suit daily topical use in this formulation. The formula is fragrance-free and cruelty-certified, reducing common irritant risk. Individual skin reactions can still vary, so performing a patch test before applying to your full face remains a sensible first step.
