Serum is a skincare product you can apply to your skin after cleansing but before moisturizing with the intent of delivering powerful ingredients directly into the skin. Serum is particularly suited to this task because it is made up of smaller molecules that can penetrate deeply into the skin and deliver a very high concentration of active ingredients. This makes them a great tool for targeting specific skincare concerns.
The age old question, is serum a moisturizer? Yes and no. Serums can be full of moisturizing ingredients (hyaluronic acid, ceramides) to help skin retain moisture. But, that doesn't make them moisturizers in the traditional sense. Face lotions and creams are richer and create a barrier on top of the skin to keep all that good stuff in.
Now let's find the right serum for your skin type.
Acne-prone skin: Look for vitamin C (increases collagen production, enhances skin’s repair process, and reduces inflammation), retinol (also an antioxidant, reduces inflammation), zinc (soothes irritation, regulates oil production), and salicylic acid (unclogs pores).
Dry skin: Look for vitamin E (an antioxidant, protects cells from oxidative damage), niacin amide (improves skin elasticity, increases ceramide levels in skin), glycolic acid (gently exfoliates and lightens discoloration), and hyaluronic acid (retains moisture).
Feeling dull: Look for antioxidants like green tea extract, resveratrol, ferulic acid (these combat free radicals, increase effectiveness of sunscreen by day, and promote cellular repair and healing by night).
** A word of caution:
Because serums are super potent, more is not always better. Be careful before piling it on. Powerful ingredients can irritate sensitive skin. Always patch-test accordingly
