Questions? We’ve got you.

Who is the Vitamin A + C Serum Duo Kit best for?
If your skin feels dull, uneven, or as though it has lost its natural rhythm, this duo is your perfect reset. It was created for anyone noticing early signs of fatigue, fine lines, or uneven tone, and wanting to bring back clarity and vitality. The system helps your skin rediscover its glow while staying calm and balanced. It is suitable for most skin types, including combination or slightly sensitive skin.
What’s included in the Vitamin A + C Serum Duo Kit?
Inside you will find Antioxidant Day Serum Vitamin C 20% and Age Defence Cream Vitamin A 1%.
The Vitamin C Serum brightens and protects your skin during the day, while the Vitamin A Cream renews and strengthens overnight. Together they form a simple, complete 24-hour system that keeps your skin radiant and resilient without overcomplicating your routine.
How does this duo work differently from single serums?
This duo was designed to follow your skin’s natural rhythm.
During the day, Vitamin C protects against free radicals, pollution, and UV stress while energizing and supporting collagen. At night, Vitamin A gently stimulates cell renewal, refining texture and helping your skin rebuild as you sleep. They work like two phases of the same conversation, each enhancing the other’s effect for balanced, visible results.
Will the Duo irritate or dry out my skin?
That is a very common concern, and it is exactly what we designed this system to prevent.
Both formulas are balanced with Niacinamide, Panthenol, and multi-weight hydrators to strengthen your barrier and keep your skin calm. A light tingle in the first few uses simply means your skin is responding to active renewal. Within days, that sensation fades, leaving your skin smoother, clearer, and comfortably hydrated.
Can I use both serums at the same time?
Use Vitamin C in the morning and Vitamin A at night.
This timing allows each formula to do what it does best. Daytime is for brightness and protection, while nighttime is for renewal and repair. Keeping them separate ensures your skin receives consistent, balanced care without irritation.
How soon will I see results?
You will notice your skin starting to change within two to three weeks.
Tone appears brighter, pores look more refined, and your complexion feels smoother. After six to eight weeks, firmness improves, fine lines soften, and your skin begins to hold its glow all day long. It is not an overnight fix, but a gradual transformation that feels natural and lasting.
I have sensitive skin. Can I still use the Duo?
Yes. Both formulas are designed to be gentle yet effective.
Start by applying the Age Defence Cream Vitamin A 1% every other night for the first week, then increase to nightly use once your skin feels ready. Keep Vitamin C 20% in your morning routine daily, followed by moisturiser and SPF. If your skin feels tight or warm, take a rest night and focus on hydration. Your skin will adjust beautifully.
Do I still need sunscreen while using this kit?
Yes, always.
Sunscreen is what keeps all your progress intact. Vitamin C protects against free radicals, but SPF is what prevents new damage from forming. Apply it every morning, even when the sky is cloudy, and your results will last longer and look more even.
Can men use the Vitamin A + C Serum Duo Kit?
Absolutely.
The textures are clean, fast-absorbing, and non-greasy, which makes them ideal for oilier or shaving-prone skin. They sink in quickly and leave the skin soft, smooth, and fresh. It is an effortless routine with visible results that fit easily into any schedule.
What if I notice flaking or tightness when I start using Vitamin A?
That means your skin is adjusting to its new renewal rhythm.
Retinyl Palmitate works gently, but during the first week you may see mild dryness or micro-flaking as old cells shed. Apply the Vitamin A Cream every other night at first and follow with a light moisturiser to keep your skin comfortable. Within a short time, it will settle into balance and begin to feel firmer and smoother.
Is the Duo safe during pregnancy or breastfeeding?
We recommend pausing Age Defence Cream Vitamin A 1% during pregnancy and breastfeeding.
You can safely continue using the Antioxidant Day Serum Vitamin C 20%, which will help maintain brightness and protection. When you are ready to return to Vitamin A, reintroduce it slowly and let your skin ease back in comfortably.
Can I combine the Duo with my existing routine?
Yes, and your skin will appreciate a simple, clear routine.
The Duo already delivers protection, brightness, and renewal, so you do not need to add other exfoliants or retinoids. Use a gentle cleanser, a light hydrating serum or moisturiser, and daily SPF. When your skin receives fewer, more purposeful signals, the results become stronger and more stable.
Can I use the Duo with professional treatments or facials?
Yes, and it is a favorite among professionals for post-treatment maintenance.
The Vitamin C Serum supports collagen and clarity, while Vitamin A strengthens the barrier and speeds up recovery. Share your routine with your aesthetician so they can tailor treatment strength if needed. Used together, your in-clinic results will last longer and your skin will stay balanced.
How long will each product last?
Each bottle typically lasts eight to ten weeks with consistent daily use.
You only need a few drops of Vitamin C Serum each morning and one to two pumps of Vitamin A Cream at night. These are concentrated formulations, so less is more. What matters most is the daily rhythm — not the quantity you apply.
How does this Duo support long-term skin health?
Over time, Vitamin C and Vitamin A retrain your skin to behave as it did when it was younger.
Vitamin C keeps collagen active and tone luminous, while Vitamin A encourages renewal and firmness overnight. Niacinamide, Panthenol, and the DNA-repairing Cassia Alata Leaf Extract (DN-Age®) keep your barrier strong and resilient. The result is skin that looks brighter, feels smoother, and functions better each day you use it.
