Hi! I’m Johanna Sfreddo, founder and CEO of My Vivere Skin. I’m excited to talk about two of my absolute favorite serums – our Brilliance C Vitamin Serum and Youth Juice Serum – and exactly how to use them. Each one is packed with unique powerhouse ingredients and amazing benefits, but they play best when used at different times of day. Let’s dive into what makes each serum special, why you shouldn’t layer them together, and how to slot Brilliance C into your morning routine and Youth Juice into your evening routine.
Brilliance C Vitamin Serum – Your Morning Radiance Elixir
Brilliance C is a vitamin C powerhouse formulated to brighten and protect your skin. It contains pure L-ascorbic acid (15%) and other stable vitamin C derivatives like magnesium ascorbyl phosphate, plus ferulic acid for extra antioxidant punch
Natural botanical extracts (rice, calendula, chamomile, etc.) hydrate and calm skin
Together, these ingredients reduce dark spots, even skin tone, and boost collagen for firmer, glowing skin
Vitamin C is famous for its brightening effect – it combats free radicals from sun and pollution, helping your skin stay youthful
In short, Brilliance C illuminates dull skin, fades hyperpigmentation, and defends against aging.
Key ingredients & benefits: Brilliance C packs multiple forms of vitamin C (L-ascorbic acid, magnesium ascorbyl phosphate, 3-glyceryl ascorbate) and ferulic acid
These fight oxidative stress and stimulate collagen synthesis for plump, firm skin. It also has soothing extracts (chamomile, calendula, etc.) to hydrate and calm. All together, this blend leaves your complexion brighter, more even, and radiant
Vitamin C benefits: As a powerful antioxidant, vitamin C helps fade dark spots and promote a glowing tone
It’s also crucial for collagen production, so using Brilliance C daily can help firm skin and smooth fine lines
Youth Juice Serum – Your Nighttime Youth Elixir
Youth Juice Serum is a soothing, hydrating treatment built around niacinamide (Vitamin B3). It contains 10% niacinamide, which smooths texture, shrinks the appearance of pores, and brightens discoloration
Niacinamide also strengthens the skin’s protective barrier, so skin retains moisture better. This serum includes sodium hyaluronate (a form of hyaluronic acid) that deeply hydrates and plumps fine lines
To calm and repair, it has chamomile (Matricaria) extract and allantoin, which soothe irritation and support healthy skin renewal
Lightweight glycerin and other humectants lock in this moisture.
Key ingredients & benefits: Niacinamide is the star – it evens skin tone and refines pores
Sodium hyaluronate floods skin with moisture, making it bouncy and supple
Chamomile and allantoin quiet redness and irritation, aiding overnight repair
The overall formula is hydrating and gentle, perfect for sensitive or aging skin.
Overnight repair: As you sleep, Youth Juice works its “magic elixir” formula to refresh your complexion. It boosts collagen renewal and helps fade the look of fine lines over time
So you wake up with smoother, more youthful-looking skin.
Why Not Use Them Together?
Both serums are amazing, but don’t layer them at the same time. Because Brilliance C is strongly acidic and Youth Juice is formulated at a higher pH, mixing them can reduce each other’s effectiveness. (Older research found that pure vitamin C and niacinamide can convert into niacin under extreme conditions, causing irritation
To be safe, apply them separately in your routine so each can work at full strength.
Use Brilliance C in the morning: Vitamin C is ideal for daytime. Apply Brilliance C after cleansing (and toning) in the AM, before your moisturizer and sunscreen
This way it can penetrate deeply and give antioxidant protection all day, and it boosts your sun defense when paired with SPF
Your skin will glow under makeup or on its own, thanks to that fresh, evened-out tone from morning C.
Use Youth Juice at night: Reserve Youth Juice for your PM routine. After cleansing, pat this serum on and let it work overnight. Niacinamide is gentle enough for night use (and won’t neutralize your morning C), and its hydrating/repairing properties go to work while you sleep. By morning, you’ll see the payoff of this nightly treatment in smoother, calm, and revitalized skin.
Glow with Confidence
By using these serums at different times, you get the best of both worlds. Brilliance C gives you that bright, protected daytime radiance, and Youth Juice delivers intensive overnight nourishment and renewal. I promise, this combination will keep your skin looking balanced, luminous, and full of life. Trust me – try Brilliance C each morning and Youth Juice each evening this July. You’ll love the results!
