Organic acids – nature-based active ingredients for skin renewal

Organic acids (e.g., fruit acids) are among the key active ingredient groups in modern skincare. They promote cell renewal, remove dead skin cells, and support the skin's protective acid mantle. The best-known include alpha hydroxy acids (AHAs) such as lactic or glycolic acid, and beta hydroxy acids (BHAs) such as salicylic acid. According to the DERMASENCE blog, these acids have exfoliating properties that improve skin texture and cleanse pores.

How do organic acids work?

These acids locally lower the pH value on the skin's surface, thereby breaking down the bonds between dead skin cells. This can make the skin surface appear smoother and increase the absorption of subsequent active ingredients. According to the AESTHETICO blog, fruit acids debunk myths such as "fruit acids are harmful to the skin" and demonstrate that they can actually strengthen the skin barrier. :contentReference[oaicite:4]{index=4}

Types of organic acids

• AHAs (Alpha Hydroxy Acids): e.g. glycolic acid, lactic acid – water-soluble, primarily act on the skin surface.
• BHAs (Beta Hydroxy Acids): e.g., salicylic acid – fat-soluble, penetrates the pores and is suitable for blemished or oily skin. According to La Roche-Posay, a fruit acid peel helps with acne and acne scars. :contentReference[oaicite:6]{index=6}
• PHAs (Polyhydroxy acids): Larger molecules that show a milder effect – better suited for sensitive skin types.

Benefits for skin structure

The application of organic acids can refine the complexion, reduce age spots, and increase the absorption of subsequent skincare products. The dm website speaks of revitalized skin when fruit acid peels are used regularly. :contentReference[oaicite:8]{index=8}

pH value, skin barrier & safety

The skin has a natural pH value in the range of approximately 4.5–5.5. Organic acids support this slightly acidic pH and thus the skin's barrier function. Increased sensitivity to UV rays after application should be noted – as the information portal NetDoktor explains: photosensitivity increases after a fruit acid peel.

Organic acids in practice with NATURFACTOR®

The Porcelain Skin Serum from NATURFACTOR® contains a select combination of plant-based fruit acid derivatives along with hydrating active ingredients. It gently supports skin renewal and optimally prepares the skin for further care – for a refined complexion and increased radiance.

Application recommendation

The products should ideally be applied in the evening after cleansing. During the day, suitable sun protection (SPF 30 or higher) is necessary, as the skin is more sensitive to light after acid treatment. Skin tolerance should be tested gradually.

Conclusion

Organic acids are effective active ingredients for skin renewal, exfoliation, and structural improvement. In modern skincare formulations, especially in high-quality products like NATURFACTOR®'s Porcelain Skin Serum, they work gently and effectively – for visibly smoother, more even, and more radiant skin.
