Choose the category based on how you want to treat or brighten your skin. For daily brightness and light hydration, select the EQQUAL BERRY Vitamin Illuminating Serum in the serums range; for targeted care and barrier support, consider the Deep Cera Vitamin Illuminating Serum in the treatments-masks family; for longer-lasting moisture and barrier care, look at the variants listed under creams-moisturizers.

The most complex attributes are Niacinamide and ceramides found across the line, and they work together to brighten the complexion while supporting the skin barrier. Niacinamide helps with even skin tone and reduces irritation, while ceramides rebuild the barrier and lock in moisture. The Deep Cera variants combine these ingredients for enhanced protective and hydrating effects, which is especially helpful if you have dry or sensitive skin.

There are options suitable for both beginners and more advanced users. For a simple, daily brightness routine, start with the standard EQQUAL BERRY Vitamin Illuminating Serum in the serums category. If you need extra barrier support or have sensitive to very dry skin, opt for the Deep Cera Vitamin Illuminating Serum (with ceramides) or Niacinamide-enriched variants.

Patch test before first use and follow proper layering. Apply the serum to clean, dry skin after washing, allow it to absorb, then seal with your moisturizer; in daytime, finish with sunscreen. Avoid mixing with potent actives unless advised by a dermatologist and keep your routine gentle if you’re adding multiple brightening products.

Variants differ in formulation focus: the standard EQQUAL BERRY Vitamin Illuminating Serum targets brightening in a lightweight serum; the Deep Cera Vitamin Illuminating Serum adds ceramides for stronger skin barrier repair; some versions include Niacinamide for added brightening and barrier support. The brand presentation spans both generic and eqqual-berry lines across serums, treatments-masks, and other categories, so choose based on your skin’s needs and routine.

Yes, you can apply makeup after the serum has absorbed, and it generally layers well with moisturizers and sunscreen. In the daytime, finish with sunscreen, and keep a light-handed approach if you use additional active treatments to avoid irritation. Always allow the serum to fully absorb before applying other products.
