Boosters are concentrated treatments that target specific skin concerns. Learn how to pick the right one for your needs with our expert guide.
Booster serums are the multitaskers of the skincare world. Unlike a standard moisturiser or cleanser, these concentrated formulas are designed to target specific skin concerns with precision. Whether you're dealing with dullness, breakouts, or sensitivity, there's likely a booster that can help. But with so many options, how do you choose the right one?
In this guide, we'll break down everything you need to know about booster serums, from how they work to how to pick the perfect one for your skin. We'll also highlight some of our favourite Pai boosters to get you started.
What Are Booster Serums and How Do They Work?
Booster serums are highly concentrated treatments that deliver active ingredients deep into the skin. They are typically lighter than moisturisers and are designed to be used underneath your daily moisturiser or mixed in with it. Think of them as a targeted treatment that addresses a specific concern, such as hyperpigmentation, fine lines, or redness.
Unlike a one-size-fits-all moisturiser, boosters allow you to customise your routine. You can choose a booster based on your skin's current needs, whether that's a hydration boost, a brightening effect, or a calming sensation. This makes them incredibly versatile and effective.
- Concentrated formulas for targeted results
- Can be used alone or mixed with moisturiser
- Ideal for addressing specific skin concerns
Identify Your Primary Skin Concern
The first step in choosing a booster serum is to identify your primary skin concern. Are you struggling with dullness and uneven tone? Or is sensitivity and redness your main issue? Perhaps you're noticing fine lines and want to boost firmness. Each concern has a booster designed to address it.
For dullness and hyperpigmentation, look for boosters with brightening ingredients like vitamin C or niacinamide. If your skin is sensitive, opt for soothing ingredients like centella asiatica or tri-mushroom. For firmness, peptides and firming agents are key.
- Dullness: seek brightening boosters with vitamin C or niacinamide
- Sensitivity: choose calming boosters with centella asiatica or mushroom extracts
- Fine lines: look for peptides or firming boosters
Consider Your Skin Type and Texture
Your skin type plays a crucial role in choosing a booster. Oily or acne-prone skin may benefit from lightweight, non-comedogenic formulas. Dry skin might need richer, oil-based boosters. Sensitive skin should avoid harsh actives and opt for gentle, soothing ingredients.
Texture also matters. Some boosters are watery and absorb quickly, while others are oil-based and provide a more emollient feel. Think about what your skin craves and what feels comfortable on your face.
- Oily skin: choose gel-based or water-based boosters
- Dry skin: opt for oil-based boosters or those with hyaluronic acid
- Sensitive skin: look for fragrance-free, alcohol-free formulas

How to Incorporate a Booster into Your Routine
Once you've chosen your booster, it's important to use it correctly. Generally, boosters are applied after cleansing and toning, but before moisturiser. You can apply a few drops directly to your face or mix them with your moisturiser for an extra boost.
Start by using the booster once a day, preferably in the evening, to allow your skin to adjust. If you have sensitive skin, patch test first and introduce it gradually. Always follow with a moisturiser to lock in the benefits, and don't forget SPF during the day, especially if your booster contains exfoliating or brightening ingredients.
- Apply booster after cleansing and before moisturiser
- Start with once daily usage, then adjust as needed
- Always use SPF during the day when using active boosters
Choosing the right booster serum doesn't have to be overwhelming. By identifying your primary concern, considering your skin type, and understanding how to layer it, you can find a booster that truly makes a difference.
