Hyaluronic Acid Intensifier

No. Hyaluronic acid is used for hydration; it is not an AHA or BHA exfoliant. The word “acid” does not make all skincare ingredients work the same way. Hyaluronic Acid Intensifier also lists panthenol, ceramide NP and beta-glucan.

Usually, yes: a hydrating serum and a moisturiser play different roles in a routine. Apply the serum as directed, then follow with a moisturiser if needed for comfort. If your skin stays tight, adding more layers of serum is not necessarily the answer.

A hydrating serum can fit into a retinal routine. Follow each product’s directions and let your skin dry before applying the retinal, then finish with moisturiser. If you are starting retinal, keep the rest of the routine simple rather than introducing several new serums at once.

Yes. Surface oil and skin hydration are different things. You can try a small amount of hydrating serum without adding several rich layers. Choose the whole routine around how your skin feels; this is not an acne treatment or a guarantee that a product will never cause a breakout.

These can have separate places in a routine, but an extra hydrating serum is optional. C E Ferulic already contains panthenol and sodium hyaluronate. If you want to use both, follow their application directions and start with fewer layers if your skin is sensitive.

Try a smaller amount and let it settle before moisturiser. Too much product or several overlapping layers can leave a tacky feel or form small rolls. Change one layer at a time to identify the cause. If your skin feels irritated rather than simply tacky, stop use.
