Skincare should be gentle, supportive, and tailored to your skin’s needs — but not all products are equally beneficial. Certain ingredients, when used regularly or in higher concentrations, may not suit every skin type and could contribute to dryness, sensitivity, or other concerns.
Whether you’re trying a new moisturizer or reviewing your current routine, being aware of ingredients to limit can help maintain your skin’s comfort and overall condition.
Here’s what many skincare professionals suggest keeping an eye on.
1. Parabens (Methylparaben, Propylparaben)
Why experts suggest limiting them:
Parabens are preservatives that help extend a product’s shelf life, but some studies have explored their potential to interfere with hormonal balance. While research is ongoing, many people choose paraben-free options as a precaution.
Commonly found in: Lotions, creams, and shampoos.
Tip: Look for “paraben-free” labels, especially in products you use daily.
2. Fragrance (Synthetic Parfum)
Why experts suggest caution:
Fragrance can make products smell appealing, but synthetic blends sometimes contain multiple undisclosed compounds that may trigger sensitivity in some individuals.
Commonly found in: Face creams, cleansers, body lotions, and hair care.
Tip: Choose “fragrance-free” rather than “unscented” for a lower chance of irritation.
3. Sodium Lauryl Sulfate (SLS) & Sodium Laureth Sulfate (SLES)
Why it may be worth avoiding:
These foaming agents help cleansers lather but can sometimes strip away too much natural oil, leaving skin feeling tight or dry.
Commonly found in: Cleansers, body washes and toothpaste.
Tip: If you have sensitive or dry skin, try a sulfate-free alternative.
4. Formaldehyde-Releasing Preservatives
Why some experts recommend avoiding them:
These preservatives help prevent microbial growth but may cause sensitivity or irritation in certain individuals.
Commonly found in: hair treatments, and some lotions.
Look for names like: DMDM hydantoin, Quaternium-15, or Diazolidinyl urea.
5. Phthalates (Sometimes Listed Under “Fragrance”)
Why experts suggest minimizing use:
Phthalates are used to make products more flexible and improve ingredient blending, but ongoing research is assessing their potential impact on hormone regulation.
Commonly found in: Fragranced skincare, and some creams.
Tip: Look for brands that disclose full fragrance ingredient lists.
6. Certain Drying Alcohols (Denatured Alcohol, Ethanol, Isopropyl Alcohol)
Why they may not suit all skin types:
While some alcohols help products feel lightweight and absorb quickly, others can cause dryness if used frequently.
Commonly found in: Toners, astringents, and acne-targeting products.
Tip: Opt for hydrating alcohols like cetyl or stearyl alcohol when possible.
7. Mineral Oil & Petroleum-Derived Ingredients
Why some skin types avoid them:
These create a protective barrier, but in certain skin types they may feel heavy or contribute to clogged pores.
Commonly found in: Moisturizers, balms, and some makeup removers.
Tip: Look for lightweight plant-based oils if you prefer a breathable texture.
8. Oxybenzone (in Sunscreens)
Why some experts prefer alternatives:
Oxybenzone is a chemical sunscreen filter that may cause skin sensitivity in some individuals and has raised environmental concerns.
Commonly found in: Sunscreens and daily moisturizers with SPF.
Tip: Try mineral-based sunscreens with zinc oxide or titanium dioxide.
9. Hydroquinone (Skin Brightening Agent)
Why its use is often regulated:
Hydroquinone can be highly effective for discoloration but may cause irritation or increased sun sensitivity. It is restricted in some countries for over-the-counter sale.
Commonly found in: Certain spot treatments and brightening creams.
Tip: Alternatives like niacinamide, azelaic acid, or vitamin C can also help improve skin tone.
10. Triclosan
Why it’s less common now:
Once used in antibacterial products, triclosan has been phased out in many regions due to concerns about resistance and environmental impact.
Commonly found in: Older antibacterial cleansers.
Tip: Choose gentle cleansers that support a healthy skin microbiome.
What This Means for Your Skincare Routine
Reading labels and learning which ingredients your skin responds well to is one of the most effective ways to build a safe, comfortable routine. Choosing simpler, well-formulated products can reduce the risk of irritation while still delivering results.
