Which form of vitamin C does the serum contain?
The Vitamin C serum features 2% Ascorbyl Glucoside, a stable Vitamin C derivative selected for its brightening properties. It also contains Ascorbyl Palmitate, another Vitamin C derivative, to complement the formula's antioxidant-focused skincare benefits.*
Is 2% Ascorbyl Glucoside the same as 2% pure vitamin C?
No. Ascorbyl Glucoside and pure L-Ascorbic Acid are different ingredients. Their percentages should not be treated as directly interchangeable measures of performance.
Can I use it in the morning and evening?
Yes. It is designed for daily use, morning and/or evening. Apply it to clean skin, follow with your favorite moisturizer, and finish with sunscreen during the day.
Does it replace sunscreen?
No. It is an antioxidant-focused skincare serum, not a sunscreen. Use a separate sunscreen for daytime UV protection.
Does Vitamin C Serum help with visible signs of aging?
Our serum contains Vitamin C derivatives, Ferulic Acid, Vitamin E, and hydrating ingredients that support a smoother, more radiant, youthful-looking complexion.*
Does it contain Hyaluronic Acid?
Yes. Our formula contains Hydrolyzed Hyaluronic Acid and Sodium Hyaluronate, which help maintain moisture and leave skin feeling hydrated, soft, and supple.*
Does Vitamin C Serum contain fragrance?
Yes. Our serum has a sweet, juicy mandarin aroma with delicate floral and citrus notes for a refreshing skincare experience.
Does it contain nut-derived ingredients?
Yes. The Serum contains Sweet Almond Oil, a nourishing ingredient that helps soften and condition the skin. If you have a nut allergy, we recommend consulting a healthcare professional before use.
What should I do if it irritates my skin?
Stop using it if redness, stinging, itching, or discomfort occurs. Try a small amount on a limited area before regular use, and seek professional advice if a reaction persists.
