Side Effects

Side Effects of Glycolic Acid & Salicylic Acid

Glycolic Acid Side Effects:

• Skin irritation
• Dryness and peeling
• Sun sensitivity
• Purging
• Allergic reactions
• Hyperpigmentation risk

Eye and mucous membrane irritation

• It is generally considered safe when used appropriately, but like any skincare ingredient can have side effects, mainly if used improperly or in high concentrations.

Skin irritation

• Skin irritation is one of the most frequent adverse effects and might appear as redness, burning, itching, or stinging. This is more likely to occur if you have sensitive skin or if you use a product with a high concentration of glycolic acid.

Dryness and peeling

• It can cause dryness and peeling, mainly when using it. This is part of the expression process, but excessive dryness can be uncomfortable.

Sensitivities of sun

• Your skin can become more sun-sensitive as a result. When utilizing glycolic acid products, it’s essential to wear sunscreen every day to protect your skin from UV ray damage.

Purging 

• Because it speeds up skin cell turnover, it occasionally can initially result in a breakout. This is frequently referred to as purging, and it should stop after a few weeks.

Allergic reactions

• Rarely, some people may be allergic to glycolic acid and have hives, swelling, or itching as a result.

Risk of hyperpigmentation

• In individuals with darker skin tones, overuse of glycolic acid might result in post-inflammatory hyperpigmentation (darkening of the skin). This is why it is essential to follow instructions carefully.

Eye and mucous membrane irritation

• Avoid getting glycolic acid near your eyes or on mucus membranes, as it can irritate. ² Side Effects | Researched based study from National Institutes of Health , ³ Side Effects | Researched based study from National Institutes of Health

Selection

Glycolic vs Salicylic Acid: Choosing the Right one

Skin type assessment

When selecting between glycolic acid and salicylic acid, begin by assessing your skin type.

Normal skin

• If your skin is relatively balanced with no significant concerns, glycolic and salicylic acids can work for you. You may choose based on your specific skin goals.

Dry or sensitive skin

• It may be less suitable for very dry or sensitive skin due to its potential for irritation. Salicylic acid in lower concentrations might be a gentler option.

Oily or acne-prone skin

• It is often favored for oily and acne-prone skin because it can unblock pores and control excess oil. However, glycolic acid can still be effective if used cautiously.

Combination skin

• You may apply various acids on various sections of your face if your skin has both oily and dry patches in order to address particular issues. ¹ Choosing the right one | Researched based study from National Institutes of Health ,⁴ Choosing the right one | Researched based study from National Institutes of Health ,⁵ Choosing the right one | Researched based study from National Institutes of Health ,⁶ Choosing the right one | Researched based study from National Institutes of Health

Consideration of skin concerns:

Acne

• Salicylic acid is typically more effective for treating acne and blackheads due to their ability to penetrate pores. However, glycolic acid can help with post-acne hyperpigmentation.

Aging and fine lines

• Due to its ability to stimulate the formation of collagen and enhance skin texture, glycolic acid is frequently chosen for its anti-aging properties.

General exfoliation

• If your primary goal is regular exfoliation and smoother skin texture, either glycolic or salicylic acid, can work depending on your skin type. ⁴ Choosing the right one | Researched based study from National Institutes of Health ,⁵ Choosing the right one | Researched based study from National Institutes of Health ,⁶ Choosing the right one | Researched based study from National Institutes of Health

Personal preferences and tolerance:

Patch test

• Always patch-test a small area of skin before using a new acid product to check for any adverse reactions or allergies.

Start slowly

• If you are new to acid treatment, start with lower concentrations and use them less frequently. Gradually increase use as your skin becomes accustomed.

Listen to your skin

• Pay attention to how your skin responds. If you experience excessive dryness or irritation, adjust your routine accordingly.

Product formulations

• Consider the form of the product you prefer, whether it’s a cleanser, toner, serum, or peel. How you include the acid into your regimen may change as a result.

Consult a professional

• When in doubt or if you have specific skin concerns, consult a dermatologist or skin care professional for personalized guidance.

Remember that everyone’s skin is unique, so there is no one-size-fits-all answer. The suitable acid for your skin depends on a combination of factors, and it is essential to tailor your skincare routine to meet your specific needs and goals. ² Choosing the right one | Researched based study from National Institutes of Health , ³ Choosing the right one | Researched based study from National Institutes of Health
