The best duo of active ingredients for skin spots, redness and acne
If you suffer from pigmentation spotsacneof rashesof blackheads or simply if you have a texture problem, I recommend using a duo of active ingredients.
From niacinamide in the morning because it has a very fluid texture and azelaic acid rather in the evening because the products with theazelaic acid can fluff up your sunscreen or make-up.
The benefits of niacinamide:
Anti-spot properties
Hyperpigmentation, or brown spots, are often persistent and difficult to eliminate with topical products alone. However, niacinamide is a remarkable ingredient for reducing them. Research shows that daily use of niacinamide at a concentration of 2-5 % for 8 weeks can significantly lighten areas of hyperpigmentation.
Repair of the skin barrier and improvement of redness
The cutaneous barrier, the skin's outer layer, is crucial for maintaining hydration and overall skin health. It consists mainly of free fatty acids, cholesterol and ceramides. The quantity and structure of these compounds directly influence the health of the skin barrier. Studies have shown that the application of 2 % niacinamide can increase the synthesis of these essential components, resulting in a stronger, healthier skin barrier.
Caution: niacinamide can sometimes cause flushing.
Anti-acne properties
Although niacinamide is not traditionally considered a primary treatment for acne, it's worth a try for those with skin problems. It has sebum-regulating and anti-inflammatory properties. One study revealed that the use of 4 % niacinamide for 8 weeks led to an improvement in skin condition in 82 % of participants, with results slightly better than those obtained with 1 % clindamycin gel, an antibiotic commonly used to treat acne.
Recommendations for niacinamide serum
Recommended morning serums include SVR's B3 ampoule, which contains hyaluronic acid and 5% niacinamide, and arma-zone's serum, which contains 10% naicinamide, copper and zinc for 6.95.

The benefits of azelaic acid:
Antibacterial properties
Azelaic acid has effective antibacterial properties against Cutibacterium acnes and Staphylococcus aureus, making it particularly useful in the treatment of acne.
Reduction of pigmentation spots
By acting on tyrosinase, the enzyme responsible for melanin production, azelaic acid helps reduce sun spots and even out skin tone. This property makes it an excellent choice for those seeking to reduce pigmentation spots.
Anti-inflammatory properties
Finally, azelaic acid is also a powerful antioxidant with anti-inflammatory properties. People with sensitive skin or those prone to redness can greatly benefit from its use, thanks to its ability to soothe and calm skin irritations.
Azelaic acid serum recommendations
For an azelaic acid serum, Théramid has a very well formulated serum that's pleasant to apply, but if you prefer a parapharmacy product, Isispharma's teenderm serum is a good option.
