Description

Serum N°04 is designed for skin prone to imperfections, excess sebum, and an imbalanced skin barrier.

It helps reduce imperfections, balance sebum, and strengthen the skin barrier.

This formula combines 18.5% carefully selected active ingredients to act on the various mechanisms involved in the appearance of imperfections, without compromising skin comfort.
Azelaic Acid (10%) helps reduce the appearance of imperfections, improve skin tone uniformity, and visibly refine skin texture.
Niacinamide (4%) complements this action by helping to regulate excess sebum while strengthening the barrier function.
Our Moisturizing Complex (3.2%) helps attract water, retain it long-term in the skin, and limit dehydration, which is often associated with blemish-prone skin.
Sage Extract (0.8%) helps balance oily skin thanks to its purifying properties, while Centella Asiatica Extract (0.5%) helps soothe the skin and support the barrier function.

A light, fresh, and quickly absorbed texture that leaves skin comfortable, balanced, and visibly clearer.

Vegan. Made in France. Fragrance-free. Non-comedogenic.

About Serum N°04

Laura F.

24 years old & oily, blemish-prone skin

So far, so good.

I originally bought this serum because azelaic acid creams tend to irritate my skin. This serum is a much gentler alternative I haven't experienced any new breakouts or irritation, so I'm really happy with it so far.

FAQ

We answer all your questions with complete transparency. Is your question not listed here? Write to us via chat or at hello@unbranded-skincare.com, and we will get back to you quickly.

Should the skin be damp or dry before applying Serum No. 04?
For Imperfection Serum No. 04, we recommend applying it to slightly damp skin.
Is Serum No. 04 suitable for all skin types?
Serum No. 04 is suitable for all skin types prone to imperfections, such as blemishes, redness, and more.
Is Serum No. 04 safe to use during pregnancy and breastfeeding?
The formula of Serum No. 04 does not contain any active ingredients known to pose a risk during pregnancy or breastfeeding. We have taken into account the needs of pregnant and breastfeeding women by using sage extract instead of salicylic acid.
Should Serum No. 04 be used in the morning or in the evening?
This imperfection serum can be used in the morning or evening. For the order of application, please refer to Questions 5, 6, and 7.
How should I incorporate Serum No. 04 into my skincare routine?
In the morning, apply this imperfection serum to slightly damp skin (after a spritz of thermal spring water, a facial mist, or following cleansing with a gentle cleanser), then follow with your moisturizer and/or SPF. In the evening, apply this imperfection serum to clean skin. For guidance on layering with Vitamin C or retinoids, please refer to Questions 6 and 7 below.
Can Serum No. 04 be used with Vitamin C?
If you are using pure Vitamin C, we recommend performing a patch test before applying it followed by Serum No. 04, to ensure that your skin tolerates both products well. If you are using a Vitamin C derivative, this imperfection serum can be applied before or after your Vitamin C treatment. The order of application mainly depends on the texture: if your Vitamin C treatment has a thicker texture than Serum No. 04, apply it afterwards. If its texture is similar to that of Serum No. 04, you can apply it either before or after.
Can Serum No. 04 be used with retinol or retinoids?
This combination may be suitable depending on your skin’s tolerance, but it should be approached with caution. We recommend introducing the products gradually, as applying Serum No. 04 after retinoids in the same routine may increase skin sensitivity due to the combined keratolytic action of azelaic acid and retinoids.
How long does Serum No. 04 last?
When used morning and evening, with 2 to 3 drops per application, Serum No. 04 should last approximately 6 to 8 weeks.
Where is Serum No. 04 made?
Serum No. 04 is proudly formulated and made in France. The bottle, manufactured in Spain, is made with 20% recycled glass. The pipette is manufactured in Italy.
Can Serum No. 04 be used by men?
Absolutely. Skincare is first and foremost about caring for and maintaining healthy skin, regardless of gender or sex. :)
