Geek & Gorgeous 101 C-Glow Serum - 15% Vitamin C

This serum is for adults seeking to improve skin brightness, even out skin tone, and protect against environmental stressors. It is suitable for all skin types.

The main benefit is the potent antioxidant protection and skin brightening provided by 15% pure Vitamin C, supported by Ferulic Acid and Vitamin E, which also boosts collagen production.

Yes, but introduce it gradually. It pairs well with antioxidants and hydrating ingredients. If using with other strong actives like retinoids or AHAs/BHAs, consider alternating application times (e.g., Vitamin C in the morning, retinoid at night) or consulting a skincare professional.

Store the serum in a cool, dark place, away from direct sunlight and heat. Keep the cap tightly sealed after use to minimize exposure to air and light.

Visible results typically appear after several weeks (4-12 weeks) of consistent, daily use, as skin cell turnover and collagen production take time.

It is formulated for all skin types, but due to the 15% Vitamin C concentration, individuals with very sensitive skin should perform a patch test and introduce the product gradually, potentially starting with every other day.

It means the serum has a very thin, fluid consistency that is easily spread and quickly absorbed into the skin, feeling lightweight and non-greasy.

This can indicate oxidation. While still potentially usable, its potency may be reduced. Store in a dark, cool place and use within the recommended timeframe after opening. Consider purchasing a new bottle if the discoloration is significant.

This is common with high-concentration Vitamin C. Start by using the serum every other day or a smaller amount. Gradually increase frequency as your skin builds tolerance. Ensure you are using a good moisturizer and daily SPF.

Ensure your skin is clean and completely dry before application. Apply only a few drops (3-4) and gently pat it into the skin. Allow it to absorb for 30-60 seconds before applying other products.
