A33 - Serum for Dark Spots and Firmness

The Serum for Dark Spots and Firmness A33 combines high-concentration tranexamic acid with a multi-functional peptide to reduce the appearance of dark spots and firm the skin.

  • A serum suitable for all skin types

    The Serum for Dark Spots and Firmness A33 is suitable for all skin types. It is particularly adapted to skin prone to pigmentation spots and lacking firmness.

  • A fluid and light texture

    The texture of the Serum for Dark Spots and Firmness A33 is a fluid and light emulsion that absorbs quickly and leaves a comfortable finish on the skin.

  • A formula enriched with unifying and firming active ingredients

    5% Tranexamic Acid:
    A synthetic derivative of lysine, an amino acid found in the skin, tranexamic acid acts on skin hyperpigmentation at its source.

    It limits the synthesis of melanin, the natural pigment responsible for skin tanning and induced by UV, by blocking the interaction between skin cells and melanocytes.

    Tranexamic acid thus visibly reduces color irregularities in the skin and improves the uniformity of skin tone.

    Tetrapeptide-2:
    Tetrapeptide-2 is a peptide composed of four amino acids. It stimulates the synthesis of key molecules involved in the support and firmness of the skin: elastin, collagen and fibrillin. It also inhibits certain reactions in the melanogenesis process and thus reduces age spots.

    Tetrapeptide-2 has a strong antioxidant power that protects the skin against free radicals and revives its natural radiance.

    Serum that delivers on its promises.

    35-44 years old 1/8/26

    I have been using this serum morning and night for a month now, and I can see a significant reduction in the appearance of the pigmentation spots on my face. The spots haven't disappeared completely, but there is a noticeable decrease in their appearance. I'm amazed because I've been trying various serums to lighten my spots for almost 2 years, and only Typology has made a difference.

    Effective

    2/19/26

    I had tried quite a few things to treat a melasma issue under my eyes. And this serum is a very nice surprise! I've been using it daily for 3 weeks, and while it hasn't completely resolved the issue, I can see a noticeable difference in the color of my skin.

  • CORINNE D. Verified buyer

    EFFECTIVE

    55-64 years old 11/23/25

    I've been using Typology skincare since May 2025 due to a flare-up of rosacea. I am very satisfied with the effectiveness of the products on my hyper-reactive skin. Since then, I haven't experienced any irritation or tightness. I have truly regained beautiful skin by strictly following my routine and also making some changes to my diet (too much sugar consumption). I had quite a few pigmentation spots on my face due to sun exposure. Since the end of August, I have applied the serum every day, morning and evening, and it has significantly reduced my spots. I've achieved a much more even complexion, and it’s glowing!
