A face serum can be a targeted addition to your daily skincare routine. But it’s best not to rely on claims such as “glow”, “intensive repair” or “anti-ageing” alone. The formula, concentration, packaging and directions for use all have a much bigger impact on whether a serum suits your routine.
A vitamin C serum with 23% ascorbic acid or a formula with 10% azelaic acid may be worth considering for targeted use, but concentrations like these need to be introduced gradually. A potent formula may cause stinging or redness, particularly if you have sensitive skin.
So start with a small amount and try any new product on a small area of skin first. Always check the current ingredients list on the packaging.
A hydrating serum without strong acids may suit many skin types. That doesn’t mean every formula is suitable for skin that reacts easily to fragrance, alcohol, essential oils or retinol.
So check the full ingredients list. For example, a serum for blemish-prone skin may contain niacinamide, salicylic acid or propolis, while a serum for redness often contains centella, panthenol or azelaic acid. The presence of an ingredient doesn’t guarantee a particular result.
Active ingredients such as retinol and pure vitamin C are sensitive to light, heat and air. Some products need to be stored in a cool, dark place. The product information for Vitamin C23 Anti aging serum even recommends keeping it in the fridge and using it within two months of opening.
When buying, check:
Don’t choose a serum just because it’s trending. Match it to one clear goal:
A retinol serum is generally used in the evening. The product information for ANUA Retinol 0.3% + Niacin Renewing Serum recommends starting slowly and using sun protection during the day. Don’t automatically combine retinol with a vitamin C serum, AHA, BHA or other potent active ingredients in the same routine.
If you’re new to serums, a simple routine is easier to follow:
A 20 or 30 ml bottle is handy if you want to try an active product first. A 55 or 100 ml ampoule may offer better value if you use a simple hydrating product every day. Also consider the texture: a watery centella ampoule feels different from an oil-based formula with exfoliating acids.
The product name alone isn’t enough. Always check the net volume and make sure the ingredients on the product match the online information. Ingredients may change.

0.3% retinol, niacinamide and several ceramides in a 30 ml serum.
We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and current European safety regulations.
Apply a few drops after cleansing and, if you use one, after toner. Gently smooth the product over your face and neck, then finish with a moisturiser. Use sun protection during the day, especially when using retinol, vitamin C or exfoliating acids.
It depends on the size and how much you use. A 30 ml bottle will usually last longer with daily use than if you apply it generously. Stick to the recommended amount and check the shelf life after opening. A product with a short period of use after opening may be less cost-effective if you don’t use it regularly.
Sometimes, but don’t automatically combine several formulas with active ingredients. For example, you could use a hydrating serum alongside a gentle niacinamide formula, but take care with retinol, high-concentration vitamin C, AHA and BHA. Introduce one new product at a time so you can better assess how your skin responds.
