SOUNDS FAMILIAR?

Here is everything you dislike about Vitamin C and what we did about it.

FORMULA

"It turned brown before I was halfway through."

Water is the main reason Vitamin C oxidises and changes colour. Our formula is water-less, so you're not racing to finish the bottle.

Texture

"It feels sticky, and pilled under my sunscreen."

Unlike other serums that feel heavy and form a layer on your skin, our serum is fast absorbing and leaves you with a soft, natural glow. So your sunscreen and makeup go on smoothly right after.

Sensation

"It stung and left my skin tight."

20% pure Vitamin C is potent, so a light tingling sensation upon first application is normal. Ease in by using it every other night, and your skin will have time to adjust.

Scent

"Why does it smell like old coins?"

That metallic smell is usually an indication of Vitamin C breaking down. Our formula is meant to withstand oxidisation and it's unscented. No added fragrance, nothing to cover up..

Results

"I can't see any difference, and I think it's breaking me out."

Old, oxidised Vitamin C does less for your skin and is a common suspect for breakouts. Ours has no water, so it's made to stay fresh, and it's set at 20% strength and pH 3.1–3.5. That's the range where pure vitamin C works best without pushing your skin harder than it needs to.

What makes our VIT-C SERUM DIFFERENT?

Pure Vitamin-C is extremely effective, yet fragile — breaking down easily, especially in water. So we worked with our Korean lab to make a waterless formula that keeps our 20% L-Ascorbic Acid stable while enhancing absorption and deepening penetration into the skin for maximum efficacy.

WATER-FREE

Our water-free formula ensures that Vitamin C is kept stable and effective for extended periods without the use of added preservatives.

OPTIMISED 20% STRENGTH

Most potent concentration and beneficial form where results peak.

Ideal pH 3.1 - 3.5 range

The optimal pH range for high penetration and low irritation.

warming delivery

Proprietary technology that gently warms the skin, helping to soften the surface and enhance absorption of key ingredients for visible results.

What our customers are saying

I'm not new to Vitamin C but the concentration of this is really potent (can feel it on the skin - light tingling). It has lightened up my dark spots a little after about a month, and I'm looking forward to better results with consistent usage. So far, I love it.
— Joys L.

This vitamin C serum has been a game-changer for my skincare routine. It's worked wonders in evening out my skin tone and brightening my complexion. I absolutely love the luxurious feeling on my skin, and I genuinely look forward to incorporating it into my daily routine. Highly recommend!
— Tammie

This vit c serum is very very good. Doesn't oxidise in the bottle too. It's way better than the ones I used to get from dermatologists. Those I bought either smelled very bad or oxidized too fast.
— Agnes

My holy grail Vitamin C product. I love being active under the sun and have some sun spots as a result. This concentrate has helped lighten my sun spots significantly after just a month and a half of use. Also helps with fine lines and gives my skin a natural glow.
— C*** Quek

YOUR QUESTIONS, ANSWERED.

Is retinal the same as retinol?

Retinal (retinaldehyde) is one conversion step closer to retinoic acid, the active form your skin actually benefits from. That means it works faster and at lower concentrations.

Because it’s often better tolerated than retinoid acid, it’s considered the smart option for those who want results without a harsh adjustment period.

Fewer steps, more efficient results.

Why is the retinal serum yellow?

That’s not artificial colouring. Retinal itself is bright yellow in its pure form. The pale golden colour you’ll see in the bottle is the ingredient doing its job.

No added dyes are used. This colour does not stain the skin, indicate oxidation, or reflect product strength.

Is this retinal serum suitable for me?

Following B/SKIN’s philosophy, this product is formulated without harmful chemicals and is designed to be gentle, barrier-friendly, and suitable for long-term use.

It is suitable for normal, combination, oily, and acne-prone skin, as well as both first-time retinal users and existing retinol users seeking improved results.

It is not recommended for pregnant women, very sensitive or compromised skin (including active eczema or open wounds), or those using prescription retinoids without professional supervision.

What’s the difference between retinal and Vitamin C?

Retinal works at night to support skin cell renewal, improve texture, and target acne. Vitamin C is best used in the morning to brighten the skin, provide antioxidant protection, and support collagen production. When used at different times of the day, both actives complement each other effectively — Vitamin C by day and Retinal by night.

How much retinal is in this serum? Is it enough to see results?

This serum delivers approximately 0.11% pure retinal — which sits at the higher end of what's typically found in retinal products on the market (where concentrations commonly range from 0.025% to 0.1%.)

Our retinal is encapsulated for stability. Using cyclodextrin-based encapsulation technology, it's protected from degradation caused by light, heat, and oxygen.

How do I care for my skin while using retinal?

Retinal helps boost skin cell turnover, so it’s best followed with a moisturiser to help lock in hydration. It can also increase skin sensitivity to UV exposure, making daily sunscreen essential to protect your skin and maintain your results.
