General Skincare

How long does it take to see results from a new skincare product?
Most skincare products require consistent use before noticeable improvements appear.

As a general guide:

  • Hydrating products: a few days to two weeks
  • Exfoliating acids: 2–6 weeks
  • Retinoids: 8–12 weeks
  • Pigmentation treatments: often 8–12 weeks or longer

Skin renewal takes time, so try to use a new product consistently for at least four weeks before deciding whether it's suitable for you.

Do I need separate day and night moisturisers?
Not necessarily.

Many people use the same moisturiser morning and evening with excellent results.

If you prefer separate products, choose:

  • A lighter moisturiser for the daytime that sits comfortably under sunscreen.
  • A richer moisturiser at night if your skin needs extra nourishment.

Can I use the same skincare routine all year round?
Yes—but your skin's needs may change throughout the year.

Many people benefit from adjusting their routine during colder weather, hotter temperatures or periods of hormonal change.

See our Winter Skincare and Summer Skincare guides for more information.

Is it bad to change skincare products frequently?
Frequent product changes make it difficult to know what's helping your skin and may increase the risk of irritation.

Introduce one new product at a time and allow your skin two to four weeks to adjust before making further changes.

Ingredients & Active Ingredients

Can I use Vitamin C and Retinoids together?
Yes, but many people find it more comfortable to use:

  • Vitamin C in the morning
  • Retinoids in the evening

This approach helps reduce the chance of irritation while allowing you to benefit from both ingredients.

What's the difference between Retinol and Retinoids?
Retinoid is the collective name for all Vitamin A derivatives.

Retinol is one type of retinoid and is generally milder than prescription-strength options such as tretinoin.

Are natural ingredients better than synthetic ingredients?
Not necessarily.

Both natural and synthetic ingredients can be highly effective—or potentially irritating.

The most important factors are how well an ingredient has been formulated, the available evidence supporting its use and whether it suits your skin.

Why does my skin sting when I use a new product?
A mild tingling sensation can occur when introducing certain active ingredients.

However, ongoing stinging, burning or discomfort usually means your skin is becoming irritated.

Stop using the product and return to a simple, barrier-supporting routine until your skin feels comfortable again.

See our Understanding the Skin Barrier guide for more information.

Skincare Routines

What order should I apply my skincare products?
As a general rule, apply products from the lightest texture to the richest.

A typical routine looks like this:
Cleanser → Toner (optional) → Serum → Active Ingredient → Moisturiser → Facial Oil (optional) → SPF (morning only)

See our Ingredient Guide: Building a Routine & Layering Order for more detail.

Do I need to double cleanse every evening?
Only if you've worn:

  • Sunscreen
  • Makeup
  • Water-resistant skincare products

Otherwise, one gentle cleanse is usually sufficient.

Can I skip moisturiser if my skin is oily?
No.

Even oily skin needs hydration.

Skipping moisturiser may leave the skin dehydrated, which can encourage increased oil production.

Instead, choose a lightweight, oil-free moisturiser.

How many active ingredients should I use at once?
Less is often more.

Most people benefit from using one active ingredient per routine, particularly in the evening.

Introducing too many active ingredients at once increases the likelihood of irritation without necessarily improving results.

SPF & Sun Protection

Do I need sunscreen if I'm indoors all day?
In many situations, yes.

UVA rays can pass through window glass and contribute to premature skin ageing.

If you spend long periods near windows or drive regularly, daily sunscreen remains worthwhile.

What SPF should I choose?
For everyday use, choose a broad-spectrum SPF 30 or higher.

Apply it generously every morning and reapply every two hours if you're spending extended periods outdoors.

Does a higher SPF mean I can apply less?
No.

Higher SPF does not replace correct application.

Regardless of whether you use SPF 30 or SPF 50, apply enough sunscreen and reapply whenever necessary.

Professional Treatments

Are professional treatments better than skincare products?
They serve different purposes.

Daily skincare provides the foundation for healthy skin, while professional treatments may help address specific concerns or enhance results.

The two often work best together rather than replacing one another.

How do I know if a treatment is suitable for me?
Suitability depends on your skin type, medical history, lifestyle and treatment goals.

A consultation with a qualified practitioner should always come before any professional treatment.

Common Skin Concerns

Can pigmentation be removed completely?
Pigmentation often improves with consistent skincare and diligent sun protection.

However, results vary depending on the underlying cause and how deeply the pigment sits within the skin.

Daily sunscreen remains one of the most important parts of managing pigmentation.

Is it normal for acne to return after it has cleared?
Yes.

Breakouts can return during periods of hormonal change, stress or lifestyle changes.

A consistent skincare routine often helps reduce flare-ups, although persistent acne may require medical advice.

Can my skin type change?
Yes.

Although genetics influence your skin type, it can change over time due to:

  • Age
  • Hormonal changes
  • Climate
  • Medication
  • Lifestyle
  • Health conditions

Review your skincare routine periodically to ensure it still meets your skin's needs.

How do I know if my skin barrier is damaged?
Signs of a compromised skin barrier may include:

  • Tightness
  • Dryness
  • Redness
  • Increased sensitivity
  • Stinging when applying skincare
  • Flaking

If these symptoms develop, simplify your routine and focus on gentle cleansing, moisturising and daily sun protection until your skin recovers.

Is more skincare always better?
Not usually.

A simple routine used consistently is often more effective than using many products at once.

Healthy skin is built through good daily habits, not by using the greatest number of products.
