Gentle Vitamin C Serum

Yes, this serum is considered safe for use during pregnancy and breastfeeding. It does not contain any ingredients of concern such as retinoids, salicylic acid, hydroquinone, or chemical sunscreens. The vitamin C derivative (3-O-Ethyl Ascorbic Acid) and niacinamide are both pregnancy-safe brightening ingredients. However, always consult your healthcare provider before adding new products to your routine during pregnancy.

Use with caution. While the formula is largely safe, it contains Bifida Ferment Filtrate (a fermented ingredient) and Castor Oil/IPDI Copolymer. Bifida is bacteria-based (not yeast like Galactomyces), so it's generally considered safer for fungal acne. However, some individuals with severe malassezia sensitivity may want to patch test first. The majority of the formula is fungal acne safe, being oil-free and free from common triggers like fatty acids and polysorbates.

Yes, but with precautions. This gentle vitamin C can generally be layered with other actives due to its stable, non-irritating formulation. For retinol: use vitamin C in the morning and retinol at night for best results. For AHA/BHA acids: allow the serum to fully absorb before applying acids, or alternate days if you have sensitive skin. The niacinamide in this formula actually pairs well with most actives and can help buffer potential irritation.

This serum is especially well-suited for sensitive skin and vitamin C beginners. The gentle 3-O-Ethyl Ascorbic Acid derivative is much less irritating than pure L-Ascorbic Acid. It works excellently for oily and combination skin due to its lightweight, non-sticky texture and niacinamide content. Dry skin types can use it too but may need a richer moisturizer on top. Those with acne-prone skin will appreciate the low comedogenic rating (1/5).

Results timeline varies by concern. Immediate hydration and glow can be noticed within 1-2 weeks. Reduced redness typically appears around weeks 3-4. Visible brightening and dark spot fading usually begins at weeks 6-8. Significant improvement in hyperpigmentation and overall skin tone requires 12+ weeks of consistent daily use. Remember to always use sunscreen during the day for optimal results, as vitamin C works synergistically with sun protection.

Apply this serum after cleansing and toning, but before heavier products like moisturizer and sunscreen. The ideal routine order is: (1) Cleanser, (2) Toner, (3) This Vitamin C Serum, (4) Any other serums (if using), (5) Moisturizer, (6) Sunscreen (AM only). You can use it both morning and evening. If using other active serums, apply them from thinnest to thickest consistency.

This serum has a low comedogenic rating of 1/5, meaning it has minimal pore-clogging potential. The water-based, oil-free formula is specifically designed to absorb quickly without leaving residue. It's free from silicones and heavy oils that typically cause congestion. Most users with acne-prone skin report no issues, though individual reactions can vary. The niacinamide content may actually help minimize pore appearance over time.

The serum has a PAO (Period After Opening) of 12 months. Thanks to the stable 3-O-Ethyl Ascorbic Acid derivative, this product won't oxidize and turn brown as quickly as pure L-Ascorbic Acid serums. Store in a cool, dark place with the cap tightly closed. If the serum changes color significantly or develops an off smell, discontinue use. The 30ml bottle typically lasts 1-2 months with daily use (2-3 drops per application).
