Understanding Acne: Types, Causes, and Treatments

What Causes Acne?

Acne develops when hair follicles become clogged with oil (sebum), dead skin cells, and bacteria (Cutibacterium acnes). This leads to inflammation and the formation of various types of blemishes.

Types of Acne

Non-Inflammatory Acne

• Blackheads (Open Comedones): Pores clogged with oil and dead cells, oxidized and appearing black
• Whiteheads (Closed Comedones): Similar to blackheads but covered by skin, appearing as small white bumps

Inflammatory Acne

• Papules: Small, red, tender bumps without visible center
• Pustules: Similar to papules but with white or yellow pus-filled center
• Nodules: Large, painful, solid lumps beneath skin surface
• Cysts: Deep, pus-filled, painful lesions that can cause scarring

Root Causes of Acne

• Hormonal fluctuations: Androgens increase during puberty, menstruation, pregnancy, or PCOS
• Excess sebum production: Overactive oil glands
• Dead skin cell buildup: Improper skin cell turnover
• Bacteria proliferation: C. acnes thrives in clogged pores
• Inflammation: Immune response to bacteria
• Diet: High-glycemic foods, dairy products may worsen acne
• Stress: Increases cortisol, triggering oil production
• Skincare products: Comedogenic ingredients clog pores

Effective Acne Treatments

Topical Treatments

• Salicylic Acid (BHA): Oil-soluble, penetrates pores to dissolve clogs (0.5-2%)
• Benzoyl Peroxide: Kills acne bacteria, reduces inflammation (2.5-10%)
• Retinoids: Increase cell turnover, prevent clogged pores (retinol, adapalene)
• Niacinamide: Regulates oil, reduces inflammation (5-10%)
• Azelaic Acid: Antimicrobial, anti-inflammatory, fades marks (10-20%)
• Sulfur: Absorbs oil, mild antibacterial properties

Acne-Fighting Routine

1. Morning: Gentle cleanser → Niacinamide serum → Moisturizer → SPF 30+
2. Evening: Cleanser → Salicylic acid or retinoid → Moisturizer
3. Spot Treatment: Benzoyl peroxide on active breakouts

Professional Treatments

• Prescription retinoids: Tretinoin, tazarotene (stronger than OTC)
• Oral antibiotics: For moderate to severe inflammatory acne
• Hormonal therapy: Birth control pills, spironolactone for hormonal acne
• Isotretinoin (Accutane): For severe, resistant acne
• Chemical peels: Professional-strength AHAs/BHAs
• Laser therapy: Reduces bacteria, inflammation

Hyperpigmentation: Dark Spots and Uneven Tone

What Is Hyperpigmentation?

Excess melanin production causing dark patches or spots on skin. Common types include post-inflammatory hyperpigmentation (PIH), melasma, and age spots.

Causes of Hyperpigmentation

• Post-inflammatory: Dark marks left after acne, injuries, or inflammation
• Sun exposure: UV rays trigger melanin production
• Hormonal changes: Pregnancy, birth control (melasma)
• Age: Cumulative sun damage over time
• Skin injuries: Burns, cuts, insect bites
• Certain medications: Some antibiotics, chemotherapy drugs

Brightening Treatments

Topical Lighteners

• Vitamin C: Inhibits melanin, brightens (10-20% L-ascorbic acid)
• Niacinamide: Reduces melanin transfer to skin cells (5-10%)
• Alpha Arbutin: Tyrosinase inhibitor, lightens spots (2%)
• Kojic Acid: Inhibits melanin production (1-4%)
• Azelaic Acid: Inhibits tyrosinase, exfoliates (10-20%)
• Retinoids: Accelerate cell turnover, fade dark spots
• Tranexamic Acid: Reduces melanin synthesis (2-5%)

Exfoliating Acids

• Glycolic Acid: Removes surface dark cells (5-10%)
• Lactic Acid: Gentler exfoliation, brightening (5-10%)
• Mandelic Acid: Gentle for sensitive skin (5-10%)

Hyperpigmentation Routine

1. Morning: Cleanser → Vitamin C serum → Moisturizer → SPF 50+ (CRITICAL!)
2. Evening: Cleanser → AHA/retinoid → Niacinamide → Moisturizer
3. Weekly: Exfoliating mask (2-3x)

Professional Treatments

• Chemical peels: Higher concentrations of AHAs, TCA
• Laser therapy: Targets melanin deposits
• Microneedling: Stimulates collagen, fades marks
• IPL (Intense Pulsed Light): Breaks up pigmentation

Timeline: Expect 8-12 weeks minimum to see visible improvement. Severe hyperpigmentation may take 6-12 months.

Enlarged Pores and Oily Skin

What Causes Enlarged Pores?

• Genetics: Pore size is largely inherited
• Excess oil production: Stretches pores
• Age: Loss of elasticity makes pores appear larger
• Sun damage: Breaks down collagen supporting pores
• Clogged pores: Buildup stretches opening
• Improper extraction: Can permanently enlarge pores

Pore-Refining Treatments

• Salicylic Acid: Penetrates and clears pores (2%)
• Niacinamide: Reduces pore appearance, regulates oil (5-10%)
• Retinoids: Increase cell turnover, prevent clogs
• Clay Masks: Absorb oil, temporarily tighten (1-2x weekly)
• AHAs: Exfoliate surface, improve texture
• Pore-minimizing primers: Blur appearance temporarily

Managing Oily Skin

• Gentle cleansing: Twice daily, avoid over-washing
• Oil-free moisturizers: Gel-based, lightweight formulas
• Blotting papers: Remove excess oil throughout day
• Mattifying products: Control shine
• Don't skip moisturizer: Dehydration triggers MORE oil production

Fine Lines, Wrinkles, and Aging

Understanding Skin Aging

Aging involves both intrinsic (natural) and extrinsic (environmental) factors:

Intrinsic Aging

• Decreased collagen and elastin production (1% less per year after 20)
• Slower cell turnover
• Reduced oil and moisture production
• Thinner skin

Extrinsic Aging (Photoaging)

• Sun exposure: Causes 80-90% of visible aging
• Smoking: Reduces blood flow, damages collagen
• Pollution: Free radical damage
• Poor diet: Lack of antioxidants
• Repetitive expressions: Create expression lines

Anti-Aging Treatments

Essential Anti-Aging Ingredients

• Retinoids: #1 anti-aging ingredient, boosts collagen (start 0.25-0.5%)
• Vitamin C: Antioxidant, stimulates collagen (10-20%)
• Peptides: Signal skin to produce collagen (Matrixyl, Argireline)
• Hyaluronic Acid: Plumps skin, holds 1000x its weight in water
• Niacinamide: Improves elasticity, reduces fine lines
• AHAs: Exfoliate, improve texture and tone
• Antioxidants: Vitamin E, ferulic acid, green tea, resveratrol

Anti-Aging Routine

1. Morning: Cleanser → Vitamin C + ferulic acid → Hyaluronic acid → Eye cream → Moisturizer → SPF 50+
2. Evening: Cleanser → Retinoid → Peptide serum → Eye cream → Rich moisturizer
3. Weekly: AHA treatment (2-3x)

Professional Anti-Aging Treatments

• Botox: Relaxes muscles, smooths expression lines
• Dermal fillers: Plumps deep wrinkles, restores volume
• Laser resurfacing: Stimulates collagen, improves texture
• Microneedling: Creates micro-injuries, triggers collagen
• Chemical peels: Improve texture, tone
• Ultherapy: Ultrasound lifts and tightens

Building Your Perfect Routine

Basic Framework for All Skin Types

1. Cleanse: Remove dirt, oil, makeup (2x daily)
2. Treat: Address specific concerns with actives
3. Moisturize: Hydrate and protect barrier
4. Protect: SPF 30-50+ every morning (even indoors!)

Layering Multiple Actives

When addressing multiple concerns:

• Thinnest to thickest: Apply products in order of consistency
• Wait time: 30-60 seconds between layers
• Alternate actives: If using multiple strong ingredients
• Start slow: Introduce one new active every 2 weeks
• Listen to skin: Reduce frequency if irritation occurs

Product Compatibility

Good combinations:

• Vitamin C + vitamin E + ferulic acid
• Retinoids + hyaluronic acid
• Niacinamide + most other ingredients
• AHAs + hyaluronic acid

Use cautiously together:

• Retinoids + AHAs (can over-exfoliate)
• Vitamin C + AHAs (pH conflicts)
• Multiple strong actives (start slowly)
