MAD Serum

The MAD Serum range brings together targeted formulas designed to slot into a daily or evening skincare routine. From retinol and glycolic acid concentrates to brightening and eye-area formulas, this collection covers the core serum types most people look for when building a routine around the MAD line. Browse the full range below or head to the MAD hub to see how serums pair with cleansers and creams from the same line.

A buying guide to MAD serums

Serums are concentrated, lightweight formulas typically applied after cleansing and before a moisturizer. Within this collection, MAD offers a few distinct directions: retinol-based serums (available in 1% strength and a higher 2% strength), an exfoliating option with the Glycolic 7% Serum, a brightening formula in the C4 Intensiv Brightening Serum, and the multi-tasking Transformation Corrective Serum. There's also a dedicated eye category, with the Eye Transformation Serum and the M.A.D Retinol Eye Serum, both formulated for the thinner skin around the eye area.

If you're building out a fuller routine, it's worth checking the MAD Cleanser range and MAD Cream collection to see complementary steps within the same line, or browse Serum more broadly if you're comparing brands.

Choosing the right serum within this category

Start by identifying what you want the serum to focus on: texture and fine lines point toward the retinol options, uneven tone points toward the brightening formula, and surface texture or dullness is where a glycolic acid serum typically comes in. Retinol strength is worth noting — the 1% and 2% versions are formulated for different tolerance levels, so newer users to retinol may prefer starting with the lower percentage. Eye-area products are formulated separately from face serums because the skin there is thinner, so it's best to keep the two categories distinct rather than substituting one for the other.

Texture and packaging also matter day to day: gel-based serums tend to layer easily under other products, while richer textures sit better for those with drier skin types. Whatever you choose, patch-test new actives and introduce them gradually, and check the full ingredient list on each product page before adding anything to your routine. For a wider view of face-focused actives and formats, the My Face and Face Care Products collections are good next stops, and the Glamour collection covers complementary cosmetic categories.

As with any active ingredient, if you have sensitive skin, are pregnant or breastfeeding, or are using other treatments, it's best to check the product label and speak with a pharmacist or dermatologist before introducing a new serum into your routine.
