Quick answer: The best ingredients for blemish-prone skin are salicylic acid (BHA) to clear pores, niacinamide to balance oil and calm redness, bakuchiol to smooth texture and marks, centella asiatica to calm inflammation, and aloe vera to soothe and hydrate. Together they treat breakouts without stripping skin, which matters because dry, irritated skin tends to break out more.
1. Salicylic acid (BHA)
Salicylic acid is oil-soluble, so it gets inside pores and dissolves the oil and dead skin that turn into blackheads and breakouts. It also calms inflammation. Willow bark and wintergreen are natural sources. Start low and slow, because too much dries skin out. Here's how BHA compares to AHA.
2. Niacinamide
Niacinamide (vitamin B3) helps regulate oil, refine the look of pores and calm redness. It also supports the skin barrier, which helps if you're using other acne treatments that tend to dry. More on niacinamide.
3. Bakuchiol
Bakuchiol is a plant-based retinol alternative. It helps smooth texture, fade the look of post-breakout marks and keep pores clear, with much less irritation than retinol. Bakuchiol vs retinol, explained.
4. Centella asiatica
Also called cica, centella asiatica is known for calming redness and supporting skin repair. It helps soothe active breakouts and can help with the look of marks left behind. More on centella asiatica.
5. Aloe vera
Aloe hydrates, cools and soothes. It won't clear a pore on its own, but it keeps skin comfortable while other ingredients do the heavy lifting, and it has antibacterial properties. More on aloe vera.

How to build a routine for blemish-prone skin
- Cleanse gently twice a day. Harsh scrubs make things worse.
- Use a BHA toner a few times a week, such as Soft Focus Daily Refining Toner.
- Apply a treatment serum. Clear Slate Pore Clearing Serum combines bakuchiol, niacinamide, centella asiatica and aloe in one step.
- Moisturize, even if you're oily.
- Wear SPF in the morning.
Give any new routine six to eight weeks before judging it. If you have deep, painful or cystic acne, see a dermatologist.
Frequently asked questions
Can you use niacinamide and salicylic acid together?

Is bakuchiol good for acne?
It can help with texture, clogged pores and post-breakout marks, and it's gentler than retinol.
Should oily, acne-prone skin use moisturizer?
Yes. Skipping moisturizer can make skin produce more oil. Choose a lightweight, non-comedogenic formula.
How long until breakouts improve?
