Many people can use salicylic acid regularly, but frequency should follow the individual product's directions, especially if your skin is new to the ingredient or prone to dryness.

Salicylic acid is oil-soluble, so it can work into the oil that collects in pores. That is why it is widely used in cleansers for blackheads and congestion-prone skin. The Tea Tree Pore Clarifying Gel Cleanser pairs it with AHA and PHA for pore-focused cleansing. Use it regularly as directed, and follow with a moisturiser and daily sunscreen, since results depend on your skin and how consistently you use it.

You can, but go slowly. Use it a few evenings a week at first, check the full ingredient list, and stop if you notice stinging, redness or tightness. If your skin is sensitive, the Alltimate Panthenol 2% Exfoliating Gel is the option to try first, as it is described as hypoallergenic and dermatologist-tested, with panthenol to keep skin comfortable. If dryness is your main concern, a gentler, hydrating face wash may suit your daily routine better.

It depends on the rest of your routine and the specific products you're using. Introducing several active ingredients at once can increase the risk of irritation, so it's generally better to introduce one new active at a time and see how your skin responds.

A salicylic acid cleanser combines regular cleansing with salicylic acid, which helps exfoliate and address excess oil and build-up.
