Blemishes can be a source of frustration and often seem to pop up out of nowhere. Whether it's acne scars, dark spots, or redness, dealing with blemishes can take a toll on your confidence. In this guide we'll cover what blemishes are, what causes them, and most importantly, how to bid them farewell for good.
To clear blemishes for good, don't strip or over-treat the skin — that damages the barrier and causes more breakouts. Instead, cleanse gently, calm and repair the barrier with anti-inflammatory ingredients like Red Algae, wear daily SPF, and support your skin from within. Red Algae is clinically shown to target redness, blemishes and pigmentation over 28 days.

What are blemishes?
The term ‘blemish' covers a range of skin imperfections, including acne scars, dark spots, hyperpigmentation, and redness — essentially any mark on the skin. They can be caused by acne breakouts, sun exposure, hormonal changes, and inflammation.
The different types of acne
Knowing which type you're dealing with helps with treatment:
- Blackheads — small dark spots of oil trapped in the pore that turns black when it meets air.
- Whiteheads — small white or skin-coloured blemishes from oil and dead skin blocking pores.
- Papules — small, hard, red bumps where oil, bacteria and dead skin cause inflammation.
- Pustules — raised red spots containing pus from collected oil, bacteria and dead skin.
- Nodules — large blemishes deep in the skin that can cause scarring.
- Acne cysts — large, swollen, painful blemishes that can cause permanent scarring.
What causes blemishes?
- Acne breakouts — clogged pores from excess oil, dirt and dead skin.
- Sun exposure — UV rays stimulate melanin, causing dark spots and hyperpigmentation.
- Hormonal changes — puberty, menstruation, pregnancy or menopause.
- Inflammation — conditions like rosacea and eczema.
- Genetics — some people are simply more prone.

Your simple anti-blemish routine
Step 3 — Protect: wear daily SPF 30+ to prevent further damage and stop existing blemishes worsening. Step 4 — Lifestyle: a balanced diet, hydration, stress management and good sleep all support clearer skin. The biggest mistake people make is over-drying the skin to “fix” blemishes — it damages the skin barrier and causes more breakouts.
