TOP 5 CLEANSER EXFOLIANTS THAT ACTUALLY WORK

Let us breakdown the few ingredients in a cleanser that can still deliver results even though it is a wash-off product.

1. SALICYLIC ACID

Naturally found in the willow bark tree. If you have acne, oily skin, whiteheads, blackheads, razor-bumps, look out for this ingredient. Salicylic acid is a BHA (beta-hydroxy acid), it is oil-soluble therefore able to penetrate deep into your skin pores to:

• Unclog pores

• Breakdown excess oil

• Reduce inflammation

• Smoothen the skin

Here is the part most people do not realise, even in a cleanser which is used for a few minutes and washed off, salicylic acid mixes with the skin's oils to effectively deliver its effects.

Unfortunately if Salicylic acid is not incorporated well in the formula, it loses it's effectiveness. We’ll break this down in detail in our next article: “Why Most Cleansers Don’t Actually Work"

2. GLYCOLIC ACID

Glycolic acid is known for one thing: Smooth, bright, youthful skin!

It is an AHA (alpha hydroxy acid) naturally found in sugarcane and beets. It works by loosening bonds between dead cells helping the skin shed off dead cells faster. Glycolic acid is able to work fat on the skin even with a short contact time.

Glycolic acid is perfect for:

• Dull skin

• Skin with uneven texture

• Early signs of darkspots

• Early signs of lines and wrinkles

Sadly, most glycolic cleansers are either too harsh or too little in the formula to cause any visible changes.

The main issue is not the ingredient but how it is formulated.

3. LACTIC ACID- GENTLE MULTI-TASKER

Cleopatra's secret of beauty, naturally found in milk. It is reported this Queen of Sheba soaked herself in milk for a glass skin glow.

Lactic acid is an AHA, it is a mild exfoliant yet also hydrates the skin meaning you get exfoliation without the tight and dry skin feel some exfoliants give.

Lactic acid is ideal for:

• Sensitive skin

• Dry skin

It's hidden advantage is that it exfoliates without drying the skin helping maintain the skin barrier. This is what most acne cleansers" ignore.

4. MANDELIC ACID -THE UNDERRATED DARKSPOT SOLUTION FOR DARKSPOTS

This exfoliant does not get enough attention as it should.

It has a large molecular structure, which means it will not penetrate deep into the skin but will work slowly on the skin surface. This is great for:

• Sensitive skin

• Melanin-rich skin

• Acne-prone skin

If you are dealing with:

• Dark-spots

• Acne break-outs on sensitive skin

• Uneven skin tone

This is one of the safest, fast working exfoliants to look for in a cleanser.

Yet most brands overlook it.

5. GLUCOLONOLACTONE-THE BARRIER-FRIENDLY EXFOLIANT

Inspired by most Korean skin care with the allure of "glass skin glow". this gentle exfoliant is the latest innovation in Cleanser formulation.

Gluconolactone is a PHA( poly hydroxy acid) that is:

• Extremely gentle

• Hydrating

• Skin-barrier protective

It does not aggressively remove dead skin cells but gradually improves skin texture whilst hydrating the skin.

It is perfect for:

• Sensitive skin

• Beginners in exfoliation

• Barrier repair routines

This is how an exfoliating cleanser is formulated without damaging the skin.

Well, you maybe thinking, "Okay.....I need a cleanser with all these exfoliant ingredients"

Not quite.

An ingredient alone does not whether a cleanser works. What actually matters is:

• The formulation process

• The pH level

• The surfactant blend

• The contact time

• The skin needs

In fact, 2 cleansers with the same ingredients can give completely different results.

So, why do most cleansers fail?

Because most are designed for:

• Marketing claims

• Abundant foam

• Fragrance experience

Not:

• Skin barrier protection

• Ingredient performance

• Long term skin health

No wonder consumers keep switching products but still do not get real results. Instead of spending years trying different cleansers, always wondering what should you buy?Best to start asking, how does this cleanser work? This is where real control begins.
