Skin care products can improve or harm the skin

Key categories include:

1. Cleansers:

Harsh cleansers with sulfates can damage the skin barrier, increasing dryness and sensitivity. pH-balanced, gentle cleansers are recommended.

Reference: Draelos, 2014 – J Dermatol Sci.

2. Moisturizers:

Contain humectants (e.g., hyaluronic acid), emollients, and occlusives. Regular use restores hydration and strengthens the skin barrier.

Reference: Lodén, 2008 – Dermatol Ther.

3. Sunscreens:

Daily broad-spectrum sunscreen protects against UV damage, reducing aging and skin cancer risk.

Reference: Wang et al., 2016 – JAMA Dermatol.

4. Exfoliants:

AHAs and BHAs promote cell renewal and treat acne. Overuse can irritate the skin.

Reference: Bissett et al., 2013 – Int J Cosmet Sci.

5. Serums:

Actives like vitamin C, niacinamide, and retinoids improve tone, texture, and reduce wrinkles—but may irritate if misused.

Reference: Zasada et al., 2017 – Clin Cosmet Investig Dermatol.

Conclusion:

Effective skin care depends on choosing suitable ingredients and applying them correctly. Scientific evidence supports consistent, gentle routines tailored to individual needs.

Hair care products can benefit or harm the hair depending on their composition and how they are used. Choosing products based on hair type, minimizing harsh chemicals, and protecting hair from heat are essential practices for maintaining healthy hair.
