The Ultimate Guide to Choosing Your Perfect Face Serum

The Ultimate Guide to Choosing Your Perfect Face Serum

Face serums are pinpoint functional products designed to combat specific skin concerns. Serums often contain a higher concentration of active ingredients compared to toners, creams or lotion and seep through the skin rapidly to intensively replenish essential nutrients, making them the most crucial step of your skincare regime.

To choose a serum that works for your skin, you should first work out your skin type and what your skin needs. In general, dry skin types can go for hydrating serums, while oily and acne-prone skin types suit serums containing acid-type ingredients. Mature skin types can consider anti-aging serums comprising collagen and antioxidants; as for sensitive skin, look for serums with simple, low-irritation formulas consisting of soothing and calming ingredients.

Hydrating Face Serums

Some common ingredients that point to a serum’s hydrating ability include hyaluronic acids, ceramides, glycerin and NMF (natural moisturizing factors). These hydrating factors quickly instill moisture into dehydrated skin and alleviate dryness-induced discomfort, dullness and fine lines.

Brightening Face Serums

Vitamin C, arbutin and niacinamide are some common components you may find on the ingredients list of a brightening serum. They help to reduce hyperpigmentation and fade dark spots and dullness, perfect for those concerned about blemishes and an uneven skin tone. See your complexion growing more and more radiant from regular usage over time!

Soothing Face Serums

Soothing serums mainly calm red, irritated and sensitized skin and usually features natural calming botanicals such as heartleaf and Centella Asiatica (cica).

Pore Minimizing Face Serums

Serums for pore concerns often involve exfoliation by using acid-based chemical exfoliators such as alpha-hydroxy acids (AHAs) and beta-hydroxy acid (BHAs) like salicylic acids to gently melt away dead skin cells on the skin’s surface. Removing impurities and old skin cells helps to regulate the skin’s metabolism and water-oil balance for smoother skin.

Anti-Aging Face Serums

Many anti-aging serums are loaded with antioxidants like vitamin C, vitamin E and Polyphenol to protect the skin against free radicals and slow down skin aging. Collagen and hydrating factors are also common additions to anti-aging formulas, as they can improve skin elasticity and moisture to reduce wrinkles and other signs of aging.
